Is There a Better Way to Write Tests?

Almost all of our are like, you know, feature tests. And then if thereis something that is really important that needs to keep working, i will write a test for that. There are only really tests for the analytic part of how, like, i analyze the menstral cycle. That is mostly because that is brute force, cause i have not come up in a very great way of doing that yet. So i just needed to have a lot of tests in place to be sure that what i am attempting to do works.
