Test Cases

A test case is a detailed, documented set of conditions and steps used to verify a specific functionality of a software application. It serves as a blueprint for a tester, outlining the exact actions to take, the data to use, and the expected outcome. A well-written test case ensures that testing is thorough, repeatable, and can be easily understood by anyone on the team.

A typical test case includes:

  • Test Case ID: A unique identifier.
  • Test Objective: The purpose of the test.
  • Preconditions: What needs to be in place before the test can run.
  • Test Steps: The exact, step-by-step actions to perform.
  • Test Data: Any data required to execute the steps.
  • Expected Result: The correct outcome of the test if it passes.
  • Postconditions: What the system should look like after the test.

Example: A tester wants to verify that the login feature works correctly. They would create a test case to check a successful login:

  • Test Case ID: TC-Login-001
  • Test Objective: Verify that a registered user can log in with valid credentials.
  • Preconditions: The user "[email protected]" exists with the password "Password123!".
  • Test Steps:
  1. Go to the login page.
  2. Enter "[email protected]" in the username field.
  3. Enter "Password123!" in the password field.
  4. Click the "Sign In" button.
  • Expected Result: The user is successfully redirected to their dashboard.
