Test Cases Writing Under the Test Types

Hello QA Community. Test cases are an essential part of software testing. Without test cases, the QA Engineer is unable to test the software properly. There are several types of test cases, each serving a specific purpose. Here are some common types of test cases:

1. Functional Test Cases

• ?These test the functionality of the software against the specified requirements.

?Examples:

1. Testing the login functionality of a website to ensure users can log in successfully.
2. Testing the comment functionality of a Facebook app to ensure users can comment on the post successfully.

2. Unit Test Cases

• ???These test individual components or functions of the software in isolation.

???Example:

1. Testing a specific function within a software module.

3. Integration Test Cases

• These test the interaction between different modules or components of the software.

???Examples:

1. Testing how well the payment module integrates with the shopping cart module in an e-commerce application.
2. Testing how to connect the WhatsApp application platform integrates with the Facebook application?

4. Regression Test Cases

• These ensure that new changes or updates to the software do not break existing functionality.

???Example:?

1. Re-running previously passed test cases after a code change to check for regressions.

5. User Interface (UI) Test Cases

• These verify the look and feel of the software, focusing on the user interface.

???Examples:?

1. ???Checking that buttons and forms are displayed correctly and are responsive.
2. ???Checking that colors, labels, and text fonts are displayed correctly according to the requirement.

6. Performance Test Cases

• These assess the software's performance under various conditions, such as load testing and stress testing.

Examples:?

1. Testing how well a web application performs when subjected to a high number of concurrent users.
2. Verify response time is not more than 4 secs when 1000 users access the website simultaneously.
3. Verify response time of the Application Under Load is within an acceptable range when the network connectivity is slow.

7. Security Test Cases

• These test the software's security features to identify vulnerabilities and weaknesses.

Examples:?

1. The password stored must be encrypted in the database.
2. Sessions and Cookies must be tested for security.
3. Checking for common security issues like SQL injection or cross-site scripting (XSS) vulnerabilities.

8. Usability Test Cases

• These evaluate the software's user-friendliness and how well it meets user expectations.

Example:

1. Conducting usability testing with real users to gather feedback on the software's ease of use.

9. Compatibility Test Cases

• These ensure that the software works correctly on various platforms, devices, and web browsers.

?Example:?

1. Testing a website to ensure it functions properly on different browsers like Chrome, Firefox, Safari and Edge.

10. Localization and Internationalization Test Cases

• ????These verify that the software can adapt to different languages and regions.

????Example:

1. Testing a mobile app to ensure it displays content correctly in various languages and date formats.

11. Exploratory Test Cases

• These are ad-hoc tests where testers explore the software without predefined scripts to uncover unexpected issues.

Example:?

1. Testers use their creativity and domain knowledge to find defects in the software.

12. Boundary Test Cases

• ?These test scenarios are at the extreme limits of input data or system conditions.

Example:?

1. Testing a calculator application to ensure it handles the maximum and minimum input values correctly.

The choice of test case types and their coverage depends on the specific needs and goals of the testing process. Different types of test cases are used in different phases of software development to ensure the software's quality and reliability.
