Software Testing Basics: A Complete Guide

Master QA fundamentals & best practices with this step-by-step guide on Software Testing basics. Analyse the various testing types, methodologies & challenges involved along with the solutions for Bug-Free Applications:

Software testing is the process of evaluation and verification of a software system or an application against the specified requirements, and ensures the system behaves as expected.

Say, for example, if you would like to order the food online, you launch the app, add the desired items to the cart. During checkout, the app suddenly freezes, and you cannot complete the payment/checkout process.

Simply didn’t go well, and placing your orders via that app has issues; this is a classic example that the software(app/software application) was not tested properly before being released to end users. These kind of issues makes Software testing a very essential and crucial part of SDLC.

Software Testing Basics: All That You Need to Know

What is Software Testing?

Software Testing plays an important role during SDLC (Software Development Life Cycle), where verification and validation of the software application/product/software system takes place to identify any potential bugs in the built software application and make sure the specified requirements are working as expected.

Verification and Validation:

Both Verification and Validation are fundamental activities in the Software Testing Life Cycle (STLC) that the Quality Assurance Testers carry out.

Verification: is checking whether the software built is correct and is as per the requirements, focusing on process, standards, design, and documentation. It does not necessarily involve the execution of the code or software.

Mostly carried out in the early phases of Requirement analysis, Designing, and Test Planning.

Examples of activities during verification are: Requirements Review, Walkthroughs, Inspections, Design review, and Code reviews.

The SRS document is fully and clearly understood, reviewing the test cases before execution and before the development process starts.

Validation is the process of checking whether the right software is built and that it is working as expected, focusing on executing the test cases of an application and making sure the product/ software application fulfills the required specifications/requirements.

Mostly carried out after the build completion and when actual testing of the software takes place.

Examples of activities during validation are: Functional testing, Regression testing, System testing, and also during User Acceptance Testing (UAT). Another example is a typical login feature to verify that users can log in to the system successfully.

Importance of Software Testing

The primary importance of robust software testing helps prevent bugs and or identify defects in the built software application, mitigate any risks, improve the overall software quality, reduce maintenance costs, enhance performance, security, and ensure user satisfaction.

Tester’s Role

Testers identify defects, validate features/functionalities, and ensure software behaves as expected.

Real-Time Example: Banking App Login Bug

A tester finds a bug where users can bypass login with a crafted URL, preventing a critical security issue from reaching customers.

The different steps involved in basic software testing are:

Roles & Responsibilities of a Test Engineer/Software Tester

One of the critical roles of any software tester is to ensure the quality, performance, and reliability of any given software application.

One of the primary responsibilities of a tester is to identify the defects and to verify functionality and make sure the software behaves as per the requirements/ user expectations before the release cycle.

Key roles and responsibilities expected of any modern testers are:

1. Understand the Software Requirements Specifications (SRS): Review and analyze functional and non-functional requirements along with testing estimations of the testing cycle.
2. Test Planning and Test Strategies: Creating test plans, objectives, and scope; how to test; appropriate methods, and tools used.
3. Test case design preparations: Creating clear, concise, step-by-step test cases, test data(actual data you provide on the application), and expected results.
4. Mapping the requirements to test cases written using RTM.
5. Manual and Automation test execution where the application resides.
6. Defect logging and tracking of the defect life cycle until closure.
7. Collaboration within the team and communication of test results, progress, and any risks noticed.
8. Automation of the test scripts is developed and maintained, running the regression suite and integrating them into CI/CD pipelines.
9. Preparing the test summary reports and status updates for the whole team involved in the project. Also worth documenting the lessons learned for future test cycles.
10. Last, continuous learning and improvement upon any new testing tools, technologies, and techniques that are coming up in the current market trends.

Also, learn about automation frameworks, performance, and DevOps practices, no-code/low-code/scriptless (AI) automation tools as and when needed.

Fundamental Concepts of Software Testing

(Let us learn detailed STLC in the upcoming sections)

Verification vs. Validation

• Verification: Ensures that the software product is built correctly (static testing).
• Validation: Ensures the right software product is built (dynamic testing).

Bug Vs. Defect

Quite often, the terms ‘Bug and Defect’ are used in Software Testing activities, but they do slightly vary in exact meaning, and it depends on the context.

All bugs may be defects, but not all defects become bugs.

Bug is a defect discovered during testing activities by the software testers and is reported using bug tracking tools like JIRA, HP Quality Center, Bugzilla, etc.

Example: Login CTA- Click To Action (Button) is not working /functioning. The testers then report this as a bug using bug-tracking tools.

Defect is a mistake in the internal code resulting in deviations from the specified requirements and or a mismatch in the actual results and expected results during both development and testing activities, respectively.

Example: The requirement is to accept a minimum of 8 characters for the Password field, but the actual Password Field is accepting less than 8 characters, say 4 or 5 characters; this is a defect.

Types of Testing

1. Functional
2. Non-functional
3. Regression
4. Smoke
5. Sanity
6. Usability
7. Performance

Levels of Testing

• Unit Testing: Test individual components
• Integration Testing: Test combined modules
• System Testing: Test the complete system
• Acceptance Testing: Verify the system meets business requirements.

Software Testing Life Cycle (STLC)

STLC- Software Testing Life Cycle is a structured, systematic approach to verify the quality and functionalities of a software application to make sure it meets the specified requirements and is defect-free.

The main goal of the STLC is to find any defects and or bugs in the software application and document them as early as possible during the initial stages of development phases (SDLC), which minimizes the risks of fixing at later stages.

There are six (6) main sequences of phases involved in the STLC, such as:

1. Requirement Gathering/Analysis
2. Test Plan & Test Case creation as per standard templates
3. Test Environment set up and sanity checks or smoke testing
4. Test Execution
5. Bug Reporting and Retesting
6. Test Closure Reports

#1) Requirements Analysis

This is the first phase of STLC, where the QA /Testing team studies or goes through the requirements documentation to understand and identify what needs to be tested.

Other activities in this stage include:

• Analyze functional and non-functional requirements.
• Asking stakeholders to gather additional information if there are any difficulties in understanding the mentioned requirements.
• Any missing information to clear the doubts and confusion around the requirements.
• Additionally, to identify any potential risks that could impact the testing process.
• Understanding the environment and data requirements.

The main purpose of studying the specified requirements analysis activities is to help create better test plans.

Deliverables are:

• Initial draft of the RTM (Requirements Traceability Matrix)
  • RTM helps with test coverage and prioritizes the high-risk areas, which focuses testing efforts effectively.
• Feasibility Report
  • A feasibility report helps determine whether the identified requirements are testable and assesses the potential for test automation

Entry Criteria to consider:

SRS is reviewed, and BRD documents and User Stories are available.

Exit Criteria to consider:

Requirements are reviewed and are testable, along with the RTM signed off.

#2) Test Planning

This is one of the most crucial phases of STLC, where the overall test strategy and test plans are created by the Test Manager /Test Lead.

The effective activities carried out in this stage are:

• Identifying the main objective and scope of testing.
• Developing the test strategy, which would include testing methods and test techniques to be used.
• Identifying and analyzing the test environment and the resources required for testing.
• Identifying the test cases that are to be executed and the test data that are to be used.
• Estimation of effort, cost, and time required for testing.
• Mark / identify the test deliverables and milestones.
• Allocation of the roles and responsibilities to the testing team.
• The final step is to review and obtain Approvals of the test plan.

Deliverables are:

• Test Plan Document is available.
• The team estimates test effort.
• Resources and schedule plans are in place.
• Risk & mitigation plans are mentioned too.

Entry Criteria to consider:

#3) Test Case Development/Design (Test Case Creation)

The test case development phase’s focus is to design and refine the test cases based on the test plan created in the previous phase.

Testers are going to create the test cases based on the requirements.

The main activities included in this phase are:

• High-level scenarios are designed and/or developed.
• Detailed test cases with steps and expected results are written.
• Test data (static or dynamic) is prepared.
• If applicable, automated test scripts are created
• The team conducts a peer review of test cases.

Deliverables include:

Actual Result	Pass: Password reset completed successfully. Fail: Reset fails, or an error is displayed.
Pass/Fail Criteria	Pass: Password reset completed successfully. Fail: Reset fails or an error is displayed.

#4) Test Environment Set-Up

In order to carry out the testing activities, first, testers need to set up the test environment, i.e., install the servers, hardware, software, and network conditions under which testing will be carried out/ executed. This usually mimics the production environment setup.

The main activities to set-up environment are:

• Installing the required software, databases, and servers, and checking on the network.
• Decide on the configuration of the test environment (on cloud, on-premise, or via virtual).
• Make sure the correct versions of OS, DB, APIs & browsers are up and running on your local machine
• To validate the environment quickly, smoke testing should be carried out for readiness

Deliverables are:

• Test environment readiness report is available
• Smoke test results are available

Entry Criteria to consider:

• Test cases and test data are ready to use.

Exit Criteria to consider

• The environment is looking stable to carry on test execution.

#5) Test Execution

After the Test Case Development and Test Environment setup phases, Test Execution is carried out to verify that the software meets the user-specified requirements

During this phase, the QA team or testers will run both manual test cases and automated test scripts, and log results accordingly.

Activities that are carried out include:

• Execution of both manual/automated test cases.
• Log test results based on the actual result outcome (pass/fail).
• Raise any defects found during execution.
• Track the defect lifecycle until closure.
• Re-testing of the fixed defects.
• If necessary, the team performs one round of regression testing.

Deliverables include:

Entry Criteria to consider:

• Test environment ready.

Exit Criteria to consider:

• All the stated/ planned test cases are executed.
• The team documents planned test case execution results and tags them with the defect ID.
• Major defects are fixed earlier and closed before the release dates.

#6) Test Closure

This is the final stage of the STLC, where the testing activities are completed as well as documented. Calling a formal closure after testing is completed.

The final activities carried out in this phase are:

• Evaluating test results against specified objectives, prepare test summary report.

The summary report may include test cases executed, pass/ fail counts, defects found, and fixed.

• Measure test metrics (defect density, test coverage).
• Conduct retrospective meetings to identify lessons learned and improve and adopt accordingly in the team.
• Archive test artifacts (test cases, test data, and reports).
• Conduct a test closure meeting and share knowledge across stakeholders.

Deliverables are:

• Test Closure report will be reviewed and approved by the client.

Software Testing Categorization

The types of Software Testing are comprehensively categorized based on the following factors.

#1) Functionalities

• Functional: Smoke, Sanity, Regression, UAT
• Non-Functional Testing: Performance, Security, Usability

#2) Test Execution Types

• Manual Testing (Exploratory testing, ad-hoc testing, best suits for UI/UX validations)

• Integration Testing
• System Testing
• UAT (User Acceptance Testing)
• Alpha & Beta Testing

#4) Objectives & Access to the Code base

How much internal code structure can testers have access to?

• Black Box Testing focuses on input and output only, with no knowledge of internal code
• White Box Testing – Code-level testing is carried out
• Grey Box Testing – Partial Knowledge of code

#5) Maintenance – Related Testing (after changes in existing code)

As mentioned below, different types of testing are performed here.

• Regression Testing
• Re-testing

#6) Modern testing types like AI testing tools, Scriptless automation tools

• AI testing
• Cloud Testing
• Mobile Testing

Types of Software Testing

There are 2 main types of approaches in Software Testing, namely:

1. Manual Testing
2. Automation Testing

#1) Manual Testing

Manual testing is carried out by QA testers/software testers manually and is best suited for usability testing and Ad-hoc testing.

Manual testing is evaluating the software application against the specified requirements manually by executing the test cases /test scenarios without using any automation tools, then verifying the results and reporting any defects noticed.

When to choose Manual Testing?

Manual testing is used when: Requirements change frequently, UI/UX testing is needed, for exploratory, ad-hoc, or usability testing, and for small or early-stage apps and one-time tests.

Manual software testing can be categorized into three main types:

1. White Box Testing
2. Black Box Testing
3. Grey Box testing

Black Box Testing

Black box testing is one of the software testing methods where software testers need not be familiar with the internal code (logic used in the internal code) of a given application or software product.

Based on the requirements, testers have to focus on the given inputs and the outputs without much knowledge of the logic of the internal code.

This Black box testing type is heavily utilized in functional testing, like validation of UI workflows and checking of the error messages.

Black Box Testing consists of 2 levels of testing:

1. Functional Testing
2. Non-Funtional Testing

Functional & Non-Functional Testing

Functional and Non-Functional testing are the major categories in the software testing life cycle (STLC).

Both testing categories are essential to ensure the software application is working as per requirements and performing well under different given conditions.

Functional Testing: The focus here is to verify ‘what the system does’, and check whether the software behaves according to the software requirements specifications. (uses Black-box testing technique). Mainly validates features, CTAs(Click To Action buttons), and business logic.

Examples: Check the login functionalities with valid and invalid inputs, the search feature, and page navigation to ensure they are navigated as expected. Also, validate API endpoint responses and Database CRUD (Create, Read, Update, Delete) operations in this type of testing.

Functional Testing includes different types of testing, such as:

Non-Functional Testing

Non-Functional Testing: The focus here in this type of testing is ‘how the system is performing under extreme conditions’, instead of behaviors, often making use of specialized tools and environments to carry out this type of testing, like Security checks, performance, load, reliability, compatibility checks, and usability testing.

Examples:

Non-Functional Testing includes different types of testing, such as

1. Compatibility Testing
2. Security testing
3. Performance Testing
4. Load and Stress Testing
5. Performance Testing
6. Usability testing
7. Localization testing

#2) Automation Testing

Automation testing is performed by using test scripts using the specified automation tools like Selenium using the Java language or any other programming languages, Appium, Playwright, Cypress, etc to execute the test scripts automatically.

Automation testing is a significant phase of software testing during the SDLC, which utilizes specific tools and or frameworks to automate the manual test cases, run/execute automatically instead of executing them manually.

Key features of automation testing are accuracy and speed, and during regression suite testing will be the ideal option, including smoke testing, API endpoints testing, and also during performance testing.

Examples:

When to choose Automation Testing?

We need to understand that automation is not for everything we test. It is best used during the occurrence of repetitive test scenarios, to be done swiftly with more accuracy.

When there are high-volume repetitive test cases that are stable and belong to regression suites and performance testing features, testers choose automation testing.

Automation testing is selected when there is a need to execute repetitive or regression test cases and during the basic checks/validation required i.e. smoke/sanity testing.

Run the test suite often, and make it as large as possible, especially when accuracy and speed are key during performance or load testing.

Project uses a CI/CD pipeline (DevOps) and, lastly, when the Application is stable with features like fixed UI workflows.

Software Testing Methodologies

Software testing methodologies are nothing but the approach, process, and strategy used during software testing to assure the quality of the product/ software application.

Software Testing Methodologies are broadly grouped as follows:

• White Box Testing Methodology
• Black Box Testing Methodology
• Grey Box Testing Methodology
• Agile Testing Methodology
• Waterfall Testing Methodology
• V-Model Testing Methodology
• Spiral Testing Methodology
• DevOps / Continuous Testing Methodology

#1) White Box Testing

White-box testing is one of the software testing methods where the developers will inspect every line of code before handing it over to the QA testing team or a designated QA team.

White-box testing is also known as transparent-box testing, open-box testing, glass-box testing, structural testing, and clear-box testing.

Unit testing is suitable for developers and security checks.

Different techniques used in White-Box testing are:

• Unit Testing
• Path Coverage
• Branch Coverage
• Statement Coverage

#2) Black Box Testing

Black box testing is one of the software testing methods wherein the software testers validate the features and functionalities of an application/product without needing to know the internal code or logic used in the internal code.

The focus is on requirements. Inputs are provided and validated to produce the expected outputs. If anyone notices a variation or defect, they log it and assign it to the developer.

Here, testers need not be familiar with programming knowledge, as this type of testing is used heavily in functional testing.

Examples: UI workflow validation, login with valid and invalid credentials, and check for error messages.

Best suited for functional, UI testing, and also UAT.

Different techniques used in Black-Box testing are:

• Boundary Value Analysis
• Decision Table,
• Use Case Testing,
• Equivalence Partitioning
• State transition.

#3) Grey Box Testing

Grey box testing is also a software testing method that follows the hybrid approach(i.e., Blackbox and White box testing techniques) wherein the software testers have partial architecture knowledge and partial internal code.

In Grey box testing, the testers can understand the data flows, DB structures, APIs, and algorithms used. Mostly used to determine any integration issues and or any DB structural issues in the software application.

Examples: APIs Endpoints formats(requests/responses), database operations testing, having SQL knowledge, and also how servers are handling the tokens.

Best suited for integration testing, API, and database testing.

#4) Agile Testing Methodology

Testing activities are integrated into each sprint cycle with continuous feedback, testing early, and testing often.

Different types are Scrum, Kanban, Test-Driven Development(TDD), BDD (Behaviour Driven Development)

#5) Waterfall Testing Methodology

This methodology uses the sequential SDLC, and testing happens only after development finishes, making changes difficult. It is suitable if the requirements are simple and stable.

#6) V-Model Testing Methodology

V-Model is nothing but verification and validation of requirements, where testing and development take place in parallel. Each of the SDLC phases has corresponding STLC phases.

Example:

• Requirements ↔ Acceptance Testing
• High-level design ↔ System Testing
• Low-level design ↔ Integration Testing
• Coding ↔ Unit Testing

Best suitable for early defect detection and is structured.

#7) Spiral Testing Methodology

This is an iterative and risk-based approach focusing mainly on prototyping and risk analysis, with continuous refinement.

Best suited for quite large and high-risk projects.

#8) DevOps / Continuous Testing Methodology

• Testing activities are integrated throughout the CI/CD pipelines
• CI-Continuous Integration
• CD-Continuous Development
• Shift-left (early testing activities)
• Shift-right (monitoring the production environment)
• Automated build and testing are available.
• The best used tools are Jenkins, Selenium, JMeter, GitLab, and Azure DevOps.

How to Write Effective Test Cases

One of the essential parts of effective test cases is to ensure that the software quality improves upon the test coverage and has clear communication among developers, QA teams, and stakeholders.

Foremost, testers must understand the requirements thoroughly and must analyze functional requirements, user stories, acceptance criteria, and any documents to identify what needs to be tested. This helps in determining both positive and negative scenarios.

The test case should mandatorily include a unique Test Case ID for traceability matrix tracking, followed by a detailed precondition section outlining system state, test data preparation, or setup steps required before execution.

The expected result is also one of the most important parts; it should clearly define the exact output the system must produce if the functionality works correctly.

Using testing techniques like Boundary Value Analysis, Equivalence Partitioning, and decision tables helps to uncover hidden defects and create efficient test coverage.

Test data should be realistic and well-defined to prevent confusion during the execution phase.

Example Test Case

Test Cases Components	Details
Test Case ID	TC001
Description	Password Reset Functionality Verification on web page
Preconditions	User is already on the “Forgot Password” page
Test Steps	1. Enter registered email. 2. Submit request. 3. Check email for reset link. 4. Click reset link to set up a new password.
Test Data	Password Reset Functionality Verification on the web page
Expected Result	Password is reset successfully, and the user can now log in with their new password.
Actual Result	To be filled after execution
Pass/Fail Criteria	To be filled after execution

Software Testing Best Practices

Software testing is an essential phase to make sure the built software application is of high quality and is defect-free.

Some of the best practices for Software testing are listed below:

• Test Planning is to be defined clearly
• Shift-Left Testing (early testing activities)
• Timely QA technical reviews.
• Where possible, testing is to be carried out on real devices.
• Communications and bug-triage meetings should be arranged.
• Define the expected output for each test case during test plan creation.
• Analyze the test results carefully to identify obvious defects or recurring issues.
• Write test cases that include both valid and invalid inputs, along with any edge cases if required.
• Performing negative testing to uncover any hidden vulnerabilities.
• Automated tests are run using CI/CD pipelines.

Common Testing Challenges and Solutions

Testing challenges that the QA team may face during testing activities are enlisted below.

Frequent changes in requirements when time is limited, unstable test environments, test data issues, communication gaps in the team, and heavy regression efforts are high.

Solutions would be to make better plans, implement potential automation coverage, ensure effective collaboration, risk-based test coverage, and strong documentation.

Here’s a breakdown of challenges and their solutions:

1. Challenges: If there is an unclear requirement, frequent changes, and or missing information, Testers may struggle to understand the requirements and wonder what to test.

Solutions: By conducting the walkthrough, clarify doubts by conducting meetings.

2. Challenges: Limited time/ tight deadlines for testing reduces the test coverage.

Solutions: Risk-based testing by practising the test cases, also by automating the regression tests, carry out shift-left testing by co-ordinating with developers to start testing early. Also, by running quick smoke tests, we can validate the core features and functionalities.

3. Challenges: Environment issues may occur because of unstable test builds/ unavailable environments, configuration errors, slow system issues, and it could be version mismatches.

Solutions: By using infrastructure monitoring tools and also maintaining proper environment documentation.

4. Challenges: May have test data issues, or even harder to create.

Solutions: Try creating the re-usable test data sets and automate test data creation through scripts.

5. Challenges: Communication gaps within the teams may delay clarifications on doubts, if any, which may lead to misalignment between the QA team, Developers and Product owners/BA.

Solutions: By using the collaboration tools like Jira, Confluence, and Slack, conduct daily standups to address the concerns or the progress, and also conduct defect triage meetings. lastly document all decisions taken and discussions.

6. Challenges: May find issues in reproducing intermittent bugs or a lack of error information.

Solutions: Collecting the error logs by enabling the debug logs in test environments, and even using screen recording tools, can help the development team to identify the root cause of an issue.

7. Challenges: Regression testing efforts may be high at times. When each of the releases requires heavy regression testing efforts, the time for manual testing may take long, become slow, and also error-prone.

Solutions: Smoke and sanity checks are done to narrow the focus by maintaining the prioritized regression suite and by automating the regression test cases.

8. Challenges: Test skills and resources may be limited due to a lack of experience in automation, security testing, and performance testing.

Solutions: By conducting workshops or by providing training, learning resources, and even mentoring. Additionally, use specialized tools to decrease the team’s skills dependency.
