How to write effective Test cases Test cases procedures and definitions Software Testing Help. Writing effective test cases is a skill and that can be achieved by some experience and in depth study of the application on which test cases are being written. Here I will share some tips on how to write test cases, test case procedures and some basic test case definitions. What is a test caseA test case has components that describes an input, action or event and an expected response, to determine if a feature of an application is working correctly. Definition by Glossary There are levels in which each test case will fall in order to avoid duplication efforts. Level 1 In this level you will write the basic test cases from the available specification and user documentation. Level 2 This is the practical stage in which writing test cases depend on actual functional and system flow of the application. Level 3 This is the stage in which you will group some test cases and write a test procedure. Test procedure is nothing but a group of small test cases maximum of 1. Level 4 Automation of the project. Compu Software. This will minimize human interaction with system and thus QA can focus on current updated functionalities to test rather than remaining busy with regression testing. So you can observe a systematic growth from no testable item to a Automation suit.

If you are working in any CMMi company then you will strictly follow test cases standards. So writing test cases brings some sort of standardization and minimizes the ad hoc approach in testing. How to write test cases Here is a simple test case format Fields in test cases Test case id Unit to test What to be verified Assumptions Test data Variables and their values.

Keep in mind while writing test cases that all your test cases should be simple and easy to understand. Dont write explanations like essays. Be to the point. Try writing the simple test cases as mentioned in above test case format. Generally I use Excel sheets to write the basic test cases. Use any tool like Test Director when you are going to automate those test cases. Feel free to comment below any query regarding test case writing or execution. System testing is the prime objective of any software product. It conducts testing of whole software product to identify the errors in software. Nikhil. Thanks vijay for this template. Can u please tell that is there need of writing the test cases in exactly the same format like verify. Many software testing guys are totally confused about Test Strategy and Test Plan Template. In this article I am concentrating on actual Sample Test Plan example.
