[DevOps] Are there any incremental methods of unit tests?

[Gy-Lu]

For now, the speed of the unit tests is too slow.

One main reason is that we do a lot of redundant unit tests. For instance, I modify some codes of low level zero, and we have to do unit tests for adam kernel, autoChunk, etc.

In fact, I have no DevOps experience and I don't know if there is a way to build a dependency tree, with which all we need to test are the parent nodes of the modified one.

I just know that this method has been in use.
