Overview

In this tutorial, we will learn how to write Test Cases for an application. Test cases should cover major functionality of the application and cover other non-functional aspects as well.

Write Test Cases

Identify the main actors and the main functionality of the application in-order to document the test cases.

Ask yourself some questions like:

• Who is going to use the System?
• What is the main intended purpose of the application for the user?
• What are the Business Goals?
• Why would the user use the System? ( Business Value)

Divide the test cases into different categories like:

Functional Test cases

• Black-box testcases( Testing without knowing the inner details of the application under test)
• White-box testcases( What’s inside the box ?  Source Code perspective testcases for example JUnit testcases)
• Integration testcases( co-existence with other systems, communication with other modules or systems)
• Usability testcases( How usable is the system? System settings, Themes, GUI , Look and Feel, Ease of Use, etc)

Non Functional Test cases

• Stress testcases ( How does the system behave under stress?  Inject Low memory faults, sandbox the app in low resources, etc )
• Performance testcases ( How does the system perform under abnormal conditions. Create concurrent virtual sessions, measure response times, SLAs)
• Security testcases ( How secure is the system?  Inject Security Threats, etc )
