Encourage to use == instead of === for writing unit tests. #36
Description
FunSuite provides === for comparison. I see == and === are used in a mixed way across unit tests. It might be great if this is encouraged documented.
See http://www.scalatest.org/getting_started_with_fun_suite
ScalaTest lets you use Scala's assertion syntax, but defines a triple equals operator (===) to give you better error messages. The following code would give you an error indicating only that an assertion failed:
assert(1 == 2)
Using triple equals instead would give you the more informative error message, "1 did not equal 2":assert(1 === 2)
