As a functional tester, the most basic requirement is to be able to write test cases. A good use case directly reflects the tester's way of thinking and rigor. So we have to think, how to write a test case, use the written use case to test and verify the product quality?

To write a good test case requires multi-faceted thinking.

1. Test case design

This is the premise of writing a good use case and analyzing the problem from different angles as much as possible. For example, look at the software from the perspective of operation and maintenance, users and so on, and design test cases respectively.

two。 Test case design method

This is a necessary skill for test engineers to divide test granularity according to the needs of the project, and then design test cases, which may be done in these ways:

Boundary value analysis: analyze the input boundary conditions and design a test case for the boundary value.

Equivalence class division method: divided into effective equivalence class and invalid equivalence method

Function diagram method: describes the process of state change and transfer of a program, because the process of running or operating software can be regarded as a process in which its state is constantly changing.

Error inference method: judge or guess, after finding the defect, design the corresponding test case, etc.

Be familiar with the business

Combine the software test engineer's business, design the case that meets the customer's requirements, and master the business in order to find the defects.

3. Basic knowledge reserve

As a software tester, personal ability also determines whether the test case is well written.

High sensitivity to software defects

Proper use of software testing tools, including TestWritrer use, operation, configuration environment, and a series of testing processes

Rich project experience

With all of the above, it is natural to write excellent test cases. Have you reached get yet?
