Module: Testify::Runner

Defined in:
lib/runner.rb

Overview

Runner is a Testify app intended to sit at the top of a Testify stack and provide a simple mechanism for running a set of tests. If you’re writing an autotest-like application, Runner is what you would use. Runner uses Templatable from the Classy gem, so you can either subclass Runner and use DSL-like class methods to define its behavior, or instantiate it directly and configure the instance.

For example,

class SampleRunner
  include Testify::Runner

  framework :rspec
  middleware :growl, :red_green
end

@runner = SampleRunner.new

would be equivalent to

@runner = Testify::Runner::Base.new
@runner.framework = Testify::Framework::RspecAdaptor
@runner.middleware = [Testify::Middleware::Growl, Testify::Middleware::RedGreen]

Which approach is best depends on your needs, or you can use a mixture of the two.

Instance Method Details

#construct_app_stack ⇒ Object

Constructs the stack of middleware and framework. If you are doing something unconventional (eg, creating middleware that requires additional initialization parameters), you may need to override this method.

def construct_app_stack

  top_app = @framework_instance

  middleware.each do |mw_class|
    top_app = mw_class.new(top_app)
  end

  top_app
end

#framework=(fw) ⇒ Object

Allows the framework to be specified on an instance of Runner. See .framework.

def framework= (fw)
  @framework = Testify::Framework::Base.find(fw)
end

#middleware=(middleware) ⇒ Object

Allows the middleware array to be specified for an instance of Runner. See .middleware.

Note: The class method accepts a list, but the instance method must be passed an actual array.

Example:

runner = YourRunner.new
runner.middleware = [:dots, :colorize]

# File 'lib/runner.rb', line 59

def middleware=( middleware )
  @middleware = middleware.map { |mw| Testify::Middleware.find(mw) }
end

#run(options = {}) ⇒ Object

Run the tests. Accepts a hash that will be merged in to the default env and passed to the Testify app stack.
