Instance Method Details

#After(*tag_names, &proc) ⇒ Object

Registers a proc that will run after each Scenario. You can register as as you want (typically from ruby scripts under support/hooks.rb).

# File 'lib/cucumber/rb_support/rb_dsl.rb', line 61

def After(*tag_names, &proc)
  RbDsl.register_rb_hook('after', tag_names, proc)
end

#AfterConfiguration(&proc) ⇒ Object

Registers a proc that will run after Cucumber is configured. You can register as as you want (typically from ruby scripts under support/hooks.rb).

# File 'lib/cucumber/rb_support/rb_dsl.rb', line 82

def AfterConfiguration(&proc)
  RbDsl.register_rb_hook('after_configuration', [], proc)
end

#AfterStep(*tag_names, &proc) ⇒ Object

Registers a proc that will run after each Step. You can register as as you want (typically from ruby scripts under support/hooks.rb).

# File 'lib/cucumber/rb_support/rb_dsl.rb', line 67

def AfterStep(*tag_names, &proc)
  RbDsl.register_rb_hook('after_step', tag_names, proc)
end

#Before(*tag_names, &proc) ⇒ Object

Registers a proc that will run before each Scenario. You can register as as you want (typically from ruby scripts under support/hooks.rb).

# File 'lib/cucumber/rb_support/rb_dsl.rb', line 55

def Before(*tag_names, &proc)
  RbDsl.register_rb_hook('before', tag_names, proc)
end

#register_rb_step_definition(regexp, &proc) ⇒ Object

Registers a new Ruby StepDefinition. This method is aliased to Given, When and Then, and also to the i18n translations whenever a feature of a new language is loaded.

The &proc gets executed in the context of a World object, which is defined by #World. A new World object is created for each scenario and is shared across step definitions within that scenario.

# File 'lib/cucumber/rb_support/rb_dsl.rb', line 95

def register_rb_step_definition(regexp, &proc)
  RbDsl.register_rb_step_definition(regexp, proc)
end

#Transform(regexp, &proc) ⇒ Object

Registers a proc that will be called with a step definition argument if it matches the pattern passed as the first argument to Transform. Alternatively, if the pattern contains captures then they will be yielded as arguments to the provided proc. The return value of the proc is consequently yielded to the step definition.

# File 'lib/cucumber/rb_support/rb_dsl.rb', line 76

def Transform(regexp, &proc)
  RbDsl.register_rb_transform(regexp, proc)
end

#World(*world_modules, &proc) ⇒ Object

Registers any number of world_modules (Ruby Modules) and/or a Proc. The proc will be executed once before each scenario to create an Object that the scenario’s steps will run within. Any world_modules will be mixed into this Object (via Object#extend).

This method is typically called from one or more Ruby scripts under features/support. You can call this method as many times as you like (to register more modules), but if you try to register more than one Proc you will get an error.

Cucumber will not yield anything to the proc. Examples:

World do
  MyClass.new
end

World(MyModule)
