How to write test cases

　　 The test case ： Conduct the test instructively , A description that helps to prove software functions or find software defects . Data design and step design of each test point .

　　 The importance of test cases ：

　　(1)、 Facilitate the implementation of the test plan

　　 Generally, it is mainly applicable to integration testing 、 The system test 、 regression testing . Know your progress according to use cases

　　(2)、 Plan the preparation of test data

　　 Such as registration , Prepare your mobile phone number in advance 、 ID number 、 No duplicate user name , Mailbox, etc

　　(3)、 The root of writing test scripts

　　 The central task of automatic testing is to write test scripts . Test scripts are based on test cases .

　　(4)、 Benchmark for evaluating test results

　　 Through the coverage and error rate of test cases , You can judge the test results , Whether it can be released

　　

　　​

　　(5)、 Analyze defect criteria

　　 Collect defects , Compare test cases . Analyze whether it is missed test or defect recurrence . It reflects the imperfection of the test , Corresponding test cases should be supplemented immediately

　　* How to write the test title ： Test point , Refine and decompose the test points . such as ： Enter the correct user name 、 password , Can I log in normally .

　　 Note the format of test case writing ：

　　(1)、 The test title must describe the test point ( Verify what you write ), Simple and clear , There are no duplicates

　　(2)、 The test steps should be instructive , It is better to include specific test data in the test data input

　　(3)、 The expected result is the only , Cannot appear “ Sending succeeded or failed ”

　　 How to write test cases ?

　　 Use cases contain ： Use case number 、 Function module 、 Use case title 、 Prerequisite 、 Operation steps 、 Expected results ( Including judgment criteria )、 The actual result 、 remarks

　　 Compiling mode ： According to the function + Business logic

　　(1)、 First, ensure that the single function is normal

　　(2)、 Then the business logic of combining functions is right

　　 such as ： Sign in 、 Recharge 、 Cash withdrawal and other functions are good . Business logic , It is to combine all the functions , See if it's good

　　 Use case coverage ： Contains positive and negative use cases

　　(1)、 Positive use cases ： According to the functional modules , For the functional modules to be tested , All test cases for normal input data are written

　　(2)、 Negative use case ： For example, login failure , Enter illegal data , Violation of unique constraints, etc
