Method: Test::Unit::Assertions#assert_equal

Defined in:
lib/test/unit/assertions.rb

#assert_equal(expected, actual, message = nil) ⇒ Object

Passes if expected == actual.

Note that the ordering of arguments is important, since a helpful error message is generated when this one fails that tells you the values of expected and actual.

Examples:

assert_equal 'MY STRING', 'my string'.upcase
