What Does It Mean to Write a Test Case?

Executing functional testing or system testing, the specialist creates and uses the test cases in his work. Often the importance and the significance of the thoughtful and well-designed test cases are underestimated.

Some testers write tests in haste and, performing unit testing or any other type of checking, even do not use their test cases. This fact will not positively affect the quality of the product under test.

Effective and sufficient load testing or performance testing requires an accurate and serious approach to the test cases writing. What does the statement “to design a test case” mean? What does the design flow include?


“Designing” Means:

  • to create a well-structured plan;
  • to predetermine the possible difficulties and challenges;
  • to demonstrate some process;
  • to intend to do something, and so on.

The test-case – in the first place, a tester’s assistance. The main task of the tests – to promote the bugs searching and detection with the minimum possible time and effort expenditures. Each expert should possess an art of the well-designed test cases creation. This will significantly accelerate and simplify the test procedure.

Also, one should take a close look at the structure peculiarities of the test case itself and the specifics of its execution procedure.
