Equivalence class: the input data can be divided into valid data and invalid data
Data entered by the object under test:
1. Effective data
2. Invalid data
To test a product, you need to consider its correct scenarios, as well as its abnormal scenarios
Boundary value: The boundary value test case is a supplement to the method of the equivalence class test case, because the method of the equivalence class test case only considers the valid data and invalid data of the input data, but does not consider the boundary situation.
Cause-and-effect diagram: refers to the fact that the measured object has multiple input conditions, and different results are matched and filtered according to the relationship between different input conditions (and, or, not)
Permutation and combination: The causal diagram is based on different input conditions to design test cases under different conditions according to permutations and combinations
Orthogonal experimental decomposition method: The causal diagram is combined according to the input N different conditions, resulting in an exponential increase in the number of test cases, which makes the test resources (manpower, time resources) unable to meet the test time requirements at all. Then at this time, it is only necessary to test representative data, and the method used is the orthogonal experimental decomposition method.
Equivalence classes are used in conjunction with boundary values
Causality Diagrams Combined with Orthogonal Experimental Decomposition
There are three test cases:
1. Mind map
2、excel
3、checklist
checklist (lists the scenarios that must be tested for the test object, but its description is relatively simple):
Checkpoint, the usage scenarios are as follows:
1. The development has been transferred to the test, but the time is very tight, and it is required to go online today, so at this time, the test writes the checklist to sort out the points that need to be tested for testing
2. Before going online, use the checklist to list the points that must be tested after going online (the test points that must be carried out often refer to the core process of a product)
