How to Make a QA Test Case
QA Test Cases are vital for consistent and reliable software testing. They ensure that software features function as expected and meet user requirements.Writing detailed and well-structured test cases helps QA teams identify defects early, reduces rework, and ultimately contributes to high-quality software delivery.
Example:
User is logged in and dashboard is displayed.
Possible values: Pass, Fail, Blocked, Not Executed
Possible values: High, Medium, Low
Example: BUG-007
Example: Retested after bug fix.
Title: Verify Login Functionality with Valid Credentials
User account is registered.
Browser is open at the login page.
Test Steps:
Navigate to the login page.
Enter "user123" in the Username field.
Enter "pass@123" in the Password field.
Click the "Login" button.
Test Data:
Username: user123
Password: pass@123
Expected Result:
User is successfully logged in and redirected to the dashboard.
Actual Result:
User is successfully logged in and redirected to the dashboard.
Status: Pass
Priority: High
Defect ID: N/A
Comments: Test executed successfully.
Test cases are a cornerstone of systematic and thorough software testing, guiding testers step by step through validation.
Purpose of a QA Test Case
- Verify that the software meets functional and non-functional requirements.
- Ensure consistency in testing by providing repeatable steps.
- Identify defects by testing different inputs, conditions, and scenarios.
- Serve as documentation for future testing cycles.
Components of a QA Test Case
Test Case ID:
A unique identifier for the test case.
Example: TC-001
Example: TC-001
Test Case Title:
A brief description of what the test case verifies.
Example: Verify login functionality with valid credentials.
Example:
User account must exist.
Browser opened to the login page.
Example:
Example: Verify login functionality with valid credentials.
Preconditions:
Any setup steps, data, or conditions required before executing the test.Example:
User account must exist.
Browser opened to the login page.
Test Steps:
A detailed, step-by-step procedure for performing the test.Example:
Navigate to the login page.
Enter valid username in the "Username" field.
Enter valid password in the "Password" field.
Click on the "Login" button.
Example:
Username: "user123"
Password: "pass@123"
Enter valid password in the "Password" field.
Click on the "Login" button.
Test Data:
Input values required for the test.Example:
Username: "user123"
Password: "pass@123"
Expected Result:
The outcome that should occur if the application behaves correctly.
Example:
Example:
User is successfully logged in and redirected to the dashboard.
Actual Result:
The actual outcome observed after executing the test.Example:
User is logged in and dashboard is displayed.
Status:
Indicates the result of the test case.Possible values: Pass, Fail, Blocked, Not Executed
Priority:
Indicates the importance or urgency of the test case.Possible values: High, Medium, Low
Defect ID (If Applicable):
Reference ID if a defect is found.Example: BUG-007
Comments:
Additional information, observations, or clarifications.Example: Retested after bug fix.

Best Practices for Writing QA Test Cases
- Write Clear and Concise Steps: Ensure test steps are easy to follow.
- Use Consistent Formatting: Follow a standard template for consistency.
- Cover Positive and Negative Scenarios: Test expected and unexpected inputs.
- Include Preconditions and Postconditions: Define starting and ending conditions.
- Keep Test Cases Independent: Avoid dependencies on other test cases.
- Make Test Cases Reusable: Write generic test cases when possible.
- Regularly Review and Update: Keep test cases aligned with software changes.
