Software Testing Life Cycle: A Comprehensive Guide to Writing Test Cases
Let’s take the example of testing a login page for a web application. Here is an example of how to write a test case for this scenario:
- Identify the Scenario: The scenario to be tested is the login page of the web application.
- Define the Test Objective: The test objective is to verify that the user can log in successfully using valid credentials.
- Define Preconditions: The precondition for this test case is that the web application is installed and accessible from a browser.
- Define Test Steps:
a. Open the web browser and navigate to the login page.
b. Enter the valid username and password into the appropriate fields.
c. Click the “Login” button.
d. Verify that the user is redirected to the home page of the application.
- Define Expected Results:
a. The login page should be displayed.
b. The valid username and password should be accepted, and the user should be logged in.
c. The user should be redirected to the home page of the application.
d. The home page should be displayed, indicating that the login was successful.
By following these steps, we have created a test case that can be used to test the login page of a web application. The test case includes the scenario, test objective, preconditions, test steps, and expected results, making it easy to understand what is being tested and what the expected outcome is.
