Dynamic Method Handling

This class handles dynamic methods through the method_missing method in the class Assert::Assertions

Class Method Details

.method_added(method_name) ⇒ Object

if a test method is added to a context manually (not using a context helper): capture any context info, build a test obj, and add it to the suite

Instance Method Details

#assert(assertion, desc = nil) ⇒ Object

check if the assertion is a truthy value, if so create a new pass result, otherwise create a new fail result with the desc and what failed msg. all other assertion helpers use this one in the end

  end
end

#assert_not(assertion, fail_desc = nil) ⇒ Object Also known as: refute

the opposite of assert, check if the assertion is a false value, if so create a new pass result, otherwise create a new fail result with the desc and it's what failed msg

#fail(message = nil) ⇒ Object Also known as: flunk

adds a Fail result to the end of the test's results break test execution if assert is configured to halt on failures
