Module: Test::Unit::Assertions
- Included in:
- TestCase
- Defined in:
- lib/test/unit/assertions.rb
Overview
Test::Unit::Assertions contains the standard Test::Unit assertions. Assertions is included in Test::Unit::TestCase.
To include it in your own code and use its functionality, you simply need to rescue Test::Unit::AssertionFailedError. Additionally you may override add_assertion to get notified whenever an assertion is made.
Notes:
-
The message to each assertion, if given, will be propagated with the failure.
-
It is easy to add your own assertions based on assert_block().

Class Method Details
.use_pp=(value) ⇒ Object
Select whether or not to use the pretty-printer. If this option is set to false before any assertions are made, pp.rb will not be required.

# File 'lib/test/unit/assertions.rb', line 1615 def self.use_pp=(value) AssertionMessage.use_pp = value end |
Instance Method Details
#add_assertion ⇒ void
This method returns an undefined value.
Called whenever an assertion is made. Define this in classes that include Test::Unit::Assertions to record assertion counts.
This is a public API for developers who extend test-unit.
