Yes. I always thought it is best to make tests deterministic. A
tests that sometimes passes and sometimes fails sounds like a
headache!<br>

<div dir="auto">But what I do is set a ‘seed’ instance
variable to a randomly generated value in initialize, and in
setUp I set a ‘random’ instance variable to ‘Random seed:
seed’. This is essentially what Leandro implemented in Bee
(he added a ‘seed’ instance variable to TestCase). In this
way, test methods can use ‘random’ freely and all is
reproducible, but the seed is not fixed (if I create a new
test suite or press the refresh button on the test runner
new seeds are used, and on the long run a much larger space
is covered in the tests).</div>

I see. You need to be careful when a test fails. Perhaps it would be
best to also include a list of seeds to always be included, and when
a test fails, you add that seed to the list. This way, it is still
useful as a regression test (as deterministic tests are).<br>
