Method: Minitest::Assertions#assert_equal

Defined in:
lib/minitest/assertions.rb

#assert_equal(exp, act, msg = nil) ⇒ Object

Fails unless exp == act printing the difference between the two, if possible.

If there is no visible difference but the assertion fails, you should suspect that your #== is buggy, or your inspect output is missing crucial details. For nicer structural diffing, set Minitest::Test.make_my_diffs_pretty!

For floats use assert_in_delta.
