When the test suite becomes large enough, our job becomes less about the fixing every flaky test. In fact, it centers on engineering a solution that will prevent all similar flaky behavior from happening.

In this chapter, we will give our tests a good solid foundation that will prevent a lot of instability in the long run. We waited until this chapter to start fixing the behavior that drives anyone who writes web tests insane, because we had to first build up a foundation of good data management and coding skills. These skills are crucial for long-term use and without them, all of the fixes of instability discussed in this chapter would be useless. Now we're ready to talk about the following topics:
