Do Internet companies do unit tests? Is it necessary to do unit testing for the needs of the bank?

Internet companies in China , There are not many single tests .

I have been thinking that there is no single test , But the overall quality can also “ The past ” What's the reason for that .

1. The main reason why there is no single test is related to the current situation of the Internet in China , China's Internet is essentially a commercial company , In the fierce competitive environment in China , It is normal that the rapid development of business leads to the rapid launch of demand . This also leads to both product and development managers , They are all based on supporting the business kpi, The second is quality .

2. A single test cannot be directly reflected in kpi The invisible demand on , Generally, there is no single test time for project scheduling .

3. The reason why the overall quality is acceptable is also because of the Internet's tolerance for quality , Some non serious problems are allowed , Need testers or qa adopt checklist、 It is enough that the improvement of integration test tools or methods can find the core problems , Even emergency recall through monitoring and user feedback is enough .

4. Secondly, due to the support of grayscale publishing mechanism , Therefore, the tolerance of software quality hazards is relatively high . This is quite different from the concept of traditional software testing , Because traditional software testing has no concept of grayscale release , Therefore, the quality control for each upcoming release will be very strict .
