This seems to be the way to go for testing.<p>I've wanted to use it for my current React-Native project. I found a JS implementation AND a babel plugin that creates the tests from flow-types.<p>The question for me here is, how long does this take compared to regular testing? I read people complained about AVA because of bad test performance (it does many parallel tests).<p>Also, where to put it in the chain?<p>Should I put it pre-push, pre-build, somewhere in the CI?
