Test method Selection Strategy

Myers Policy:

• In any case, boundary value analysis must be used, and experience has shown that this method is the most capable of designing a test case to find errors.

• If necessary, some test cases are supplemented by equivalence class partitioning methods.

• Add some test cases with the error-guessing method.

• Check the logical coverage of the designed test cases against the logic of the program, and if you do not meet the required coverage criteria, you should add enough test cases.

• If the function description of the program contains the combination of input conditions, then the causal diagram can be selected from the outset.

Policy flow:

1, according to the requirements, design specifications and other relevant instructions to construct basic test case types

2. Using boundary value method to supplement test case

3. Supplementary test cases by equivalence class partitioning method

4. Construct positive and negative test cases according to the relevant test type

5. Using the error-guessing method to supplement the test case

6, according to the situation using the method:

• Design test Cases using scenario method

• Using orthogonal test method/function diagram method to design test case

• Design test Cases using Causality diagram method

• Design test Cases using flowchart method

• State Transition Supplemental Test Cases

7. Write test cases for other test types, such as performance, pressure, security, compatibility, configuration, localization, internationalization, etc.

8. Optimize test Cases by inspiring review methods

Risk-Based testing: depending on the risk level of the SOFTWARE PRODUCT, the severity of the error and the probability of occurrence are calculated, and the test can determine the priority of the test and the coverage of the test according to the different risk levels.

Risk-based testing and analysis process:

1. List all functions and features of the software;

2, determine the likelihood of each function error;

3, if a function error or lack of a feature, the impact on the customer how much;

4, calculate the risk degree;

5, according to the indications of possible errors, to modify the degree of risk;

6, determine the scope of testing, write test plan.
