Here are a few examples of test cases that you might design for different types of software:
- Login functionality test case: This test case would verify that a user is able to successfully log in to the application using a valid username and password, and that the appropriate error message is displayed if an invalid login attempt is made.
- Calculator functionality test case: This test case would verify that the calculator application is able to perform basic arithmetic operations (e.g., addition, subtraction, multiplication, division) correctly, and that it displays the correct result.
- Performance test case: This test case would verify that the application performs well under a specified load, by simulating a high number of users accessing the application simultaneously and measuring the response time.
- Compatibility test case: This test case would verify that the application is compatible with different web browsers and operating systems, by testing it on a variety of different platforms.
- Usability test case: This test case would verify that the application is easy to use and navigate, by having test users perform a series of tasks and evaluating their experience.
