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 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 cleanup
    #...
  end

  def teardown
    #...
  end

  def test_my_method1
    #...
  end

  def test_my_method2
    #...
  end
end

Here is a call order:

  1. startup

  2. setup

  3. test_my_method1

  4. cleanup

  5. teardown

  6. setup

  7. test_my_method2

  8. cleanup

  9. teardown

  10. shutdown

You can set an attribute to each test.

Example:

class TestMyClass < Test::Unit::TestCase
  attribute :speed, :fast
  def test_my_fast_method
    # You can get the attribute via `self[]`
    self[:speed] # => :fast
    #...
  end

  attribute :speed, :slow
  def test_my_slow_method
    self[:speed] # => :slow
    #...
  end
end

    .ractor(options = {})  ⇒ void 
  



  

    
This method returns an undefined value.


Declares that the following test uses Ractor.



Tests that use Ractor are executed at the end. Because multi Ractor mode is enabled in the current process and it’s not disabled even when only one Ractor is running after running a test that uses Ractor on Ruby 3.0. It will be solved in the future.



This is implemented by setting the :ractor attribute of the test to true.


  





    

    
Examples:

        


Declares that test_do_something_with_ractor uses Ractor



      
ractor
def test_do_something_with_ractor
  Ractor.new do
    # ...

    .shutdown  
  



  

    

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 << self
    def shutdown
      #...
    end
  end

  def teardown

    .startup

  class << self
    def startup
      #...

    .sub_test_case(name) { ... } ⇒ TestCase 
  



  

    

Defines a sub test case.



This is a syntax sugar. The both of the following codes are the same in meaning:



Standard:



class TestParent < Test::Unit::TestCase
  class TestChild < self
    def test_in_child
    end
  end
end



Syntax sugar:



class TestParent < Test::Unit::TestCase
  sub_test_case("TestChild") do
    def test_in_child
    end
  end
end



The difference of them are the following:


  • 

    ::Test case created by sub_test_case is an anonymous class. So you can’t refer the test case by name.
    

  • 

    The class name of class style must follow constant naming rule in Ruby. But the name of test case created by sub_test_case doesn’t need to follow the rule. For example, you can use a space in name such as “child test”.
    



  





  
Parameters:


    
  
  • 
    name
    (String)
—    
    

    The name of newly created sub test case.
    

    
  
    • 



Yields:


    
  
  • 
    
    
    

    The block is evaluated under the newly created sub test case class context.
    

    
  
    • 



Returns:


    
  
  • 
    (TestCase)
—    
    

    Created sub test case class.

    .test(*test_description_or_targets, &block)

In declarative syntax usage, the following two test definitions are the almost same:



description "register user"
def test_register_user
  #...
end

test "register user" do
  #...
end



In test method mark usage, the “my_test_method” is treated as a test method:

    #==(other)  
  



  

    

It’s handy to be able to compare TestCase instances.

def ==(other)
  return false unless other.kind_of?(self.class)
  return false unless @method_name == other.method_name
  return false unless data_label == other.data_label
  self.class == other.class

def add_assertion
  current_result.add_assertion
end


  








  

    #add_pass  ⇒ void 
  



  

    
This method returns an undefined value.


Notify that the test is passed. Normally, it is not needed because #run calls it automatically. If you want to override #run, it is not a good idea. Please contact test-unit developers. We will help you without your custom #run. For example, we may add a new hook in #run.



This is a public API for developers who extend test-unit.

    #assign_test_data(label, data)  
  

  

    This method is for internal use only.
  



  

    

Assigns test data to the test. It is used in internal.


  



  [ GitHub ]


  

  


# File 'lib/test/unit/testcase.rb', line 534



def assign_test_data(label, data) # :nodoc:

end


  








  

    #cleanup  
  



  

    

Called after every test method runs but the test method isn’t marked as ‘passed’. Can be used to clean up and/or verify tested condition. e.g. Can be used to verify mock.



You can add additional cleanup tasks by the following code:



class TestMyClass < Test::Unit::TestCase
  def cleanup
    #...
  end

  cleanup
  def my_cleanup1
    #...
  end

  cleanup do
    #... # cleanup callback1
  end

  cleanup
  def my_cleanup2
    #...
  end

  cleanup do
    #... # cleanup callback2
  end

  def test_my_class
    #...
  end
end



Here is a call order:


  • 

    test_my_class
