Picking a good test value

And avoid flaky tests

This is a lesson I learned the hard way: Be careful when picking test values to make sure they can't collide with random faker data.

For example, if you're testing a wild card search against a few fields, don't use "ok" as your test value. Why not? Well, Faker can generate a random name that could potentially match, like "Brooks".

When this happens, your test will randomly fail, but then pass if you run it again. It might only happen one out of 500 test runs. Flaky tests are so frustrating!

Choosing a slightly more complex value like "search-term" can save you grief later.
