How to write test cases?

To write scenarios, first you need to identify the requirements. You need to read all the business rules and functional flow from SRS and BRS documents.

After requirement clarity, clear the types of testing required by client either they want only functional testing in application or they want load testing, database testing or any other type of testing in application.

If client requires only functional testing, identify the functional positive and negative scenarios in application and start writing in following format.

Make following columns in excel sheet.

1.       Test Case ID

2.      Module Name

3.      Requirement Number (Trace from SRS, BRS directly)

4.      Title of scenario

5.      Prerequisites

6.      Test Data

7.      Steps to be executed

8.      Expected Result

9.      Actual Result

10.   Pass/Fail

11.    Fail Bug ID

12.   Comments

Make sure you cover all the positive and negative scenarios to test the application which makes 100% coverage of your testing in the application. Let me know if any query.
