Strict compare === at least in tests

[Glutexo]

If I recall correctly, in JavaScript and PHP worlds, comparing strictly by default is considered good practice; loose comparison should be only used conciously to avoid type conversion. I am, however, not sure how this works in Elixir.

Apparently, the strict equal === operator is only useful when comparing integers and floats. Other types are never equal if they are of different types. The strict comparison only adds a redundant type checking instruction.

See Structural comparison for more information on comparison in Elixir. Closing this issue as not required.
