BICEP Unit Test Plan-arithmetic-test

One or 6 specific areas worth testing, they can improve your testing skills

• Right-is the result correct?
• B is all the boundary conditions correct?
• Can I check the inverse association?
• C-Can you cross-check the results with other means?
• E-Can you force error conditions to occur?
• P Whether meets performance requirements

Second, the test module

Test in the occurrence of multiplication method and addition and subtraction process, whether there will be non-conforming to the operational rules of the data, such as the occurrence of a divisor of 0, judging the program running data in other modules, in the test of this module, the data used in other modules to determine the data range (0-1000), and in the test process, Force a divisor of 0 error conditions, and make the meiosis greater than the meiosis, the divisor is greater than the divisor, the test difference appears negative and the quotient false score is correct

Third, the test plan

R, test whether the module is running correctly by entering representative data

B, referring to external conditions, random number generation scoping, you can avoid the original data is not within the scope of the situation

I, to determine whether the raw data is processed by checking the results of the generated data

C, by modifying the program parameters to meet the test requirements, check the results

E, test what happens to the module by forcing the error condition to occur

P, change the judging conditions, check whether the results meet the requirements

V. Test results

Addition Test Results

Subtraction Test Results

Multiplication test Results

Division test results

VI. Analysis of test results

In the process of programming, each module should have a corresponding test module, in order to avoid the entire program, the problem is difficult to find or find the wrong place, in addition, writing test module, can help improve the whole program, is a good programming habit
