Smoke test and regression test

Regression testing refers to modifying the oldCodeThen, repeat the test to confirm that the modification does not introduce new errors or cause other code errors. Automatic regression testing will greatly reduce the cost of system testing, maintenance, and upgrade. Regression testing, as a part of the software life cycle, occupies a large workload throughout the software testing process. Multiple regression tests are performed at each stage of software development. In progressive and rapid iterative development, continuous release of new versions makes regression testing more frequent. In extreme programming methods, regression testing is required several times a day. Therefore, it is very meaningful to improve the efficiency and effectiveness of regression testing by selecting the correct regression testing strategy.

The smoke test found a problem in the test and found a bug. Then the developer will fix the bug. At this time, I want to know if this fix is actually fixed.ProgramTo solve this problem, or whether it will affect other modules. This process is called smoke test. In many cases, smoke test is a series of chained reactions of other functional modules when developers try to solve a problem, the reason may be that you only focus on the problem at the beginning, and ignore other problems, which may lead to new bugs. Smoke test has the advantage of saving test time and preventing build failure. The disadvantage is that the coverage rate is relatively low. Smoke Testing is a free test.
