测试质量衡量标准（Test quality measurement standard）Quality scale (scale)
Product quality can be clearly quantified
Test coverage - code block coverage, function coverage, u So much coverage, per coverage, what is the reasonable target? 50%, 80%, 100%
According to the number of defects found, how much is found by the ur, how much is found by the internal non test team, and how much is found by the test team, which is one of the measures of quality
Recurrent number of recurrent defects
Patches and Service package quantities are ud to measure quality
We have so many standards that can be ud to measure quality. So what should be the core standards, the most important universal standards? How do you relate the standards to the quality?
Setting out quality indicators and what is the correct indicator can guide us to decide whether to relea or delay the relea of the product until we reach the target

How do you determine the end of a test point for a software?
Before the software dies, if there is no end point of the test, then the software test will never end, and it will never end. The end point of software testing, according to the specific circumstances of their own company to develop, can not be generalized! Personally, the testing end point is determined by the following conditions:
husbands1. bad on the "test pha" principle:peter pan
Each software test usually goes through unit testing, integration testing and system testing. We can t up detailed test end points for unit test, integration test and system test respectively. Each test pha meets the end criteria and then tests at the latter stage. For example: unit testing, we require testing end points must satisfy the "100% core code by Code Review", "functional coverage rate reached 100%, the coverage rate of not less than 80% lines of code, there is no A and B defect, all defects found at least 60% are included in the defect tracking system and all levels of defect repair rate reached the standard of" standard. The end points of integration testing and system testing are formulated as related end standards, and so are of cour.
2., bad on the principles of test cas:

The test designer designed the test cas and asked the members of the project team to participate
in the review. Once the test ca was approved, the latter test could rve as a reference for the end of the test. For example, if the test ca pass rate is too low during the test, you can refu to continue testing until the developer fixes it. The pass rate of function test cas is 100%, and the non functional test cas reach more than 95%, which allows the normal end of the test. However, it is critical to grasp the quality of the test cas when using this principle as the end point of the test.
3., bad on the principle of "defect convergence trend":
The life cycle of software testing with the test time, defect map line test found first, gradually increasing, and then test
to a certain stage, and defects of a downward trend, until the discovery of almost zero defect or difficult to detect defects so far. We can determine whether the test can end through the tendency of the trend line of the defect, which is also a criterion.
4. bad on the principle of defect recovery rate:
Software defects are divided into veral levels in the test life cycle. They are: rious errors, major errors, minor errors, general errors, minor errors, and 6 suggestions for testing. Then we test in deter
mining the end point, rious mistakes and main defect repair error rate must reach 100%, does not allow the existence of functional errors; minor errors and wrong defect repair rate must reach more than 85%, allowing the prence of a small amount of functional defects, solve the defect repair for later versions; low error best rate reached 60%~70% above. For the propod test questions, you can not modify it for the time being.
5. bad on the principle of acceptance test:
上海健身学院Many companies are doing project software, if this is to determine the end of the test point, it is best to test a certain stage, to reach or clo to the test department designated standards, then submit the ur acceptance test. If the ur acceptance testing, you can immediately terminate the test department of the test; if the customer acceptance tests, and found some defects, it is possible to modify the defects of, after verification by the client, the corresponding test can be ended.
6., bad on the principle of coverage:
For the test "coverage" principle, personal feel as long as the test ca coverage "covers all the customer software requirements, including industry hidden demand, functional requirements and performance requirements and so on, as long as the execution of a test ca coverage rate reached
100%, basically can end test. For example, the minimum coverage of a ntence in a unit test should not be less than 80%, the test ca execution coverage rate should be 100%, and the test coverage requirement should be 100%, which can be ud as the end of the determination point. If you're not sure, you have to look at the execution of the test ca and check if the u ca is missing. You can do sample testing and random testing of commonly ud functions". For coverage, unit testing, integration testing, and system testing can not be ignored at each stage.

In most cas, each project will be prepared to develop and test from the beginning of the Schedule, in the corresponding test plan will also be a corresponding milepost, restrictions on the test schedule and test end point, will generally and project team members (development, management, testing, marketing, sales) to reach a connsus after the team agreed to develop a standard end point. If one aspect of the project is delayed, the test time is shortened accordingly. In most cas, all the required test content and regression tests have been completed and can rve as an end point. Many non-standard software
