3 Minutes With Kent

Today I was in a piano discussion for test JS Summit and a question was asked about like what's the use case for unit tests if we focus on integration and component level tests. And I talked about this and and it was kind of more about like what what's the shape of our testing trophy or testing pyramid or whatever like where do we focus our tests? And I talk about how I recommend that you focus on integration and component-type tests and try to mock as little as possible. I typically don't mock modules all that often and most often will just.Mock HTTP requests unless we're doing end tests in which case you mock nothing. And the the way that I think about it is like if you just have 100% unit tests and that's all that you're writing and you get a hundred percent code coverage with that you're still very likely to have lots of bugs creep up as integrations between different pieces of these units change. And that can be very difficult to track when you are just mocking all the modules and just unit unit testing
