Overview

Ties everything together. If you subclass and add your own test methods, it takes care of making them into tests and wrapping those tests into a suite. It also does the nitty-gritty of actually running an individual test and collecting its results into a Test::Unit::TestResult object.

You can run two hooks before/after a TestCase run.

Example:

class TestMyClass < Test::Unit::TestCase
  class << self
    def startup
      ...
    end

    def shutdown
      ...
    end
  end

  def setup
    ...
  end

  def teardown
    ...
  end

  def test_my_method1
    ...
  end

  def test_my_method2
    ...
  end
end

Here is a call order:

* startup
* setup
* test_my_method1
* teardown
* setup
* test_my_method2
* teardown
* shutdown

Constructor Details

#initialize(test_method_name) ⇒ TestCase

def initialize(test_method_name)
  throw :invalid_test unless respond_to?(test_method_name)
  test_method = method(test_method_name)
  throw :invalid_test if test_method.arity > 0
  if test_method.respond_to?(:owner)
    if test_method.owner.class != Module and
        self.class != test_method.owner
      throw :invalid_test
    end
  end
  @method_name = test_method_name
  @test_passed = true
  @interrupted = false
end

# File 'lib/test/unit/testcase.rb', line 89

def inherited(sub_class)
  DESCENDANTS << sub_class
end

.shutdown ⇒ Object

Called after every test case runs. Can be used to tear down fixture information used in test case scope.

Here is an example test case:

class TestMyClass < Test::Unit::TestCase
  class << self
    def shutdown
      ...
    end
  end

  def teardown
    ...
  end

  def test_my_class1
    ...
  end

  def test_my_class2
    ...
  end
end

Here is a call order:

* test_my_class1 (or test_my_class2)
* teardown
* test_my_class2 (or test_my_class1)
* teardown
* shutdown

Note that you should not assume test order. Tests should be worked in any order.

# File 'lib/test/unit/testcase.rb', line 183

def shutdown
end

.startup ⇒ Object

Called before every test case runs. Can be used to set up fixture information used in test case scope.

Here is an example test case:

class TestMyClass < Test::Unit::TestCase
  class << self
    def startup
      ...
    end
  end

  def setup
    ...
  end

  def test_my_class1
    ...
  end

  def test_my_class2
    ...
  end
end

Here is a call order:

* startup
* setup
* test_my_class1 (or test_my_class2)
* setup
* test_my_class2 (or test_my_class1)

Note that you should not assume test order. Tests should be worked in any order.

def startup
end

.suite ⇒ Object

Rolls up all of the test* methods in the fixture into one suite, creating a new instance of the fixture for each method.
