Running Rake tasks in Rspec Tests
RubyRuby on-Rails-3RspecTddRakeRuby Problem Overview
I am building up an integration test suite and there is one bit of logic that I need to have a clean database for. How can I run the db:test:purge task inside of one of my tests?
I am using: ruby 1.9.2, rails 3.0.9, rspec 2.6
Ruby Solutions
Solution 1 - Ruby
You can invoke Rake tasks as following:
require 'rake'
Rake::Task[name].invoke
In this case this would result in the following code:
require 'rake'
Rake::Task['db:test:purge'].invoke
Solution 2 - Ruby
Approved answer didn't work for me, when I needed to execute my own rake task
Here's my solution
Put in the top of the spec file
require 'rake'
Place these lines where you need to execute your custom rake task, e.g. rake update_data from the file example.rake
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)
Solution 3 - Ruby
If we require to use multiple rake tasks we can add
require "rake"
Rails.application.load_tasks
Then simply call any task.
Rake::Task['sync:process_companies'].invoke
Though I cant confirm if its slower because it loads all the tasks
Solution 4 - Ruby
for me (rails-6)
Rails.application.load_tasks
Rake::Task['app:sync'].invoke
=> require not necnessary in my case
Solution 5 - Ruby
We need to require the task also
require 'rake'
Rake.application.rake_require 'tasks/new_adapter'
After this, just call the task
Rake::Task['new:adapter'].invoke
Solution 6 - Ruby
Many of the above answers worked for me for running a single spec. However, I had to take an extra step when running multiple specs for a single rake task.
After each spec, I had to run Rake::Task.clear, as (for some reason) the task would not be run again if it was registered as being already_invoked (i.e. if Rake::Task['my_task'].already_invoked returned true.
I added the following line to my rake task spec:
after { Rake::Task.clear }
and everything worked as expected when running multiple tests for the same rake task.
