As we mentioned in front of the test implementation of an effectiveness strategy, it is actually a typical example showing the contradiction between effectiveness and risk. This relationship between the effectiveness and risk of test methods, actually manifested throughout the test cycle, exists throughout the development cycle.
1. Effectiveness and risk, first embodying the consolidation of a test concept. Although, when we ask a test engineer, what is the test? She / he may not hesitate to test the defect. When she / he manages a test item or test, it always wants to prove that all functions are normal, and greatly reduces the efficiency of the test. At least, in your heart, the result may go to take some risks, may sacrifice some efficiency.
2. In the development of test strategies, test programs, validity and risk contradictions may be more prominent, that is, the quality standards, test scope and test focus of tests are determined. "How to reduce the test range, seize the test key" is a skillful, skill and experience to improve test effectiveness, and sometimes it is often a risk that it is easy to ignore. Quality standards (specific requirements for product features) also have a struggle for marketing requirements and engineering (Engineering), also a balanced art.
3. When designing test cases, we often hurt the "granularity" of the test case. If the test case is designed very well, take care of each data entry, each condition, every environment, each path, then the number of test cases will be huge, although the risk is very small, but the test efficiency will be very Low, and the test does not think about the space, it may make the test executor becomes dull (unless all test automation), do not need creativity, thinking. The test case design is very thick, the test efficiency may be higher, the tester has a space that makes testing more interesting, but this depends on personal responsibility and ability, and the risk is much larger.
4. This relationship is also highlighted in execution, talk more, please refer to: http://blog.9cbs.net/kerryzhu/archive/2006/06/14/796881.aspx
