Does software development require testers?

This is an extremely controversial topic. I have been arguing with csdn for a long time. My point is that all "testers" can complete the task."Program"Members" can be done, and what can be done is no worse than "tester. Of course, no one can convince anyone.

I am not trying to convince anyone, but just a few simple opinions. It also has practical significance to reduce the size of the organization and reduce costs. Or there are some private secrets-as a programmer, I always hope the programmer can get better treatment.

Such remarks will inevitably stimulate the majority of IT colleagues who are specialized in testing. Here, I am deeply sorry. I don't want anyone to feel bad or lose any job. I want to do something that I think is correct, or prove that it is incorrect.

This is an introduction to clarify my point of view and describe my position. In the futureArticleI will try to prove its validity, rationality, and operability.
