System test exit standard

1) the system test case design has passed the review

2) the system test is completed according to the system test plan.

3) the functional coverage of the system test is 100%.

4) the function and performance of the system meet the requirements of the product specification.

5) the errors found in the system test have been modified and the defect repair rate at all levels has reached the standard.

6) there are no A, B, C defects after system testing.

7) Class D defects are allowed, not more than 5% of the total defects

8) Class E defects are allowed to exist, not exceeding 10% of the total defects

Residual defect assessment:

1) the number of residual defects is equal to the number of defects found in the last regression test.

2)

Second, the most valuable criterion is to describe the conditions for ending the test in terms of the exact number; it needs to involve the prediction of the period of error discovery.

Related to:

Defect rate (Defect Rate): the percentage of defects found after all test cases have been executed

Defect density (Defect Density): the number of defects found per unit length (1000 lines of normal bits) code or FP (Function Point)

Test coverage (Test Coverage): the extent to which code or use case is covered during testing
