Use message param
The message param is invaluable in case test fails – if you use it to display relevant info, you will find out what went wrong much faster.
Reworking the silly example above:
assert some_list.include?(5)
will only tell you that
<false> is not true.
which isn’t terribly helpful, is it? But if you use message like that:
assert some_list.include?(5), "some_list = #{some_list.inspect}"
the output will be:
some_list = [1, 2]. <false> is not true.
which in most cases should give you strong hints as to why the test failed.
