Running Rake Tasks in Rspec Tests

Question

I am creating a set of integration tests, and there is one bit of logic for which I need a clean database. How to run a db:test:purge task inside one of my tests?

I use: ruby ​​1.9.2, rails 3.0.9, rspec 2.6

Answer 1

You can invoke Rake tasks as follows:

 require 'rake' Rake::Task[name].invoke 

In this case, this will result in the following code:

 require 'rake' Rake::Task['db:test:purge'].invoke 

Answer 2

The approved answer didn't work for me when I needed to complete my own rake task

Here is my solution

Insert the top of the specification file

 require 'rake' 

Put these lines where you need to execute your own rake command, for example. rake update_data strong> from example.rake file

 load File.expand_path("../../../lib/tasks/example.rake", __FILE__) # make sure you set correct relative path Rake::Task.define_task(:environment) Rake::Task["update_data"].invoke 

My environment:

 rails (4.0.0) ruby (2.0.0p195) rspec-core (2.14.7) rspec-expectations (2.14.3) rspec-mocks (2.14.4) rspec (2.14.1) rspec-rails (2.14.0) 

Answer 3

If we need to use multiple rake tasks, we can add

 require "rake" Rails.application.load_tasks 

Then just call any task.

 Rake::Task['sync:process_companies'].invoke 

Although I can’t confirm if it is slower because it loads all tasks
