To run a single test in Rails, we normally do:
rails test TEST=test/system/invitation_test.rb
But that doesn't work with system tests. Neither do this work:
rails test:system TEST=test/system/invitation_test.rb
With both those commandos above, all system tests (files) are run.
So my question is, how can I run a single system test?
As a side note, to run (all) system tests in Rails, you need to append :system to test.
rails test:system
While rails test doesn't seem to work if you want to run your system tests (you need to append test with :system), if you only want to run a single test it does seem to work:
rails test test/system/my_little_test.rb
I am using RSpec with RoR 4.1, if I run
bundle exec rspec spec/requests/citilink_request_spec.rb
or
bundle exec rspec spec
Then rspec will load the files correctly if it is the first execution, but at the second execution, it'll load the cached file. I can confirm this that the backtrace produced refer to the old point which I swapped with comment. It refers to a comment!
How can I disable this functionality, it shouldn't be de default setting IMHO.
It is not RSpec problem, but Sidekiq. Yah, I am using Sidekiq. And the Sidekiq part not loading again my code whenever it changes. So, I need to reload the Sidekiq and everything works as expected.
I should have mentioned that the code in question is working asynchronously in a worker executed by Sidekiq that is using Redis.
I'm trying to set up a rails/backbone/jasmine suite, and I'm having a problem getting jasmine-headless-webkit to run.
If I run the jasmine suite via guard, it passes, but if I run jasmine-headless-webkit from console, I get:
2013-01-01 10:06:22.855 jasmine-webkit-specrunner[1809:707] *
WARNING: Method userSpaceScaleFactor in class NSView is deprecated on
10.7 and later. It should not be used in new applications. Use convertRectToBacking: instead. SyntaxError: Parse error
Test ordering seed: --seed 5430
And no tests run.
Just to clarify, the jasmine suite not only loads, but passes via Guard...but no joy at all in jasmine-headless-webkit. Any ideas appreciated
Old question, but if anyone is still looking for the best way to run Jasmine tests headless, look into the Snapdragon project, available here: https://github.com/reachlocal/snapdragon
I have a small test project that I'm using to test the waters for a much larger project. I am using rspec on rails for testing, but recently looked into Cucumber. It looks very nice, but I'm wondering if there's a way for cucumber to run my spec tests, or for rspec (autospec) to run my cucumber features. I've looked around extensively, but have yet to find a solid conclusion.
Thanks,
Mike
I've been experimenting with Cucumber as well. It supports autotest:
AUTOFEATURE=true autospec
That runs both the rspec & cucumber test suite continuously.
An easy way to do this would be to create a Rake task that invokes both tools, such as this minimal example:
desc 'Run rspec + cucumber'
task :build => [:spec, :features]
Then you can build both with:
rake build
Both RSpec and Cucumber come with some default tasks which work with Rails, but you can customize the tasks to suit your needs. There's more info on writing rake tasks here.
Depends on what you are looking for, but the best way to run cucumber tests with rspec is to use turnip, which uses exactly the same feature syntax as cucumber (the syntax is called gherkin), but allows you to use most of the functionality of rspec. https://github.com/jnicklas/turnip.
If you want to take things one step further, you can run your features from inside rspec _spec.rb files using a gem we created called rutabaga. https://github.com/simplybusiness/rutabaga
In both cases, all the tests can be run by executing rspec or bundle exec rspec as needed.
Whenever I run rspec tests for my Rails application it takes forever and a day of overhead before it actually starts running tests. Why is rspec so slow? Is there a way to speed up Rails' initial load or single out the part of my Rails app I need (e.g. ActiveRecord stuff only) so it doesn't load absolutely everything to run a few tests?
I definitely suggest checking out spork.
http://spork.rubyforge.org/
The railstutorial specifically addresses this, and gives a workaround to get spork running nicely in rails 3.0 (as of this moment, spork is not rails 3 ready out of the box). Of course, if you're not on rails 3.0, then you should be good to go.
The part of the tutorial showing how to get spork running in rails 3.0

Checking when spork is rails 3.0 ready

You should be able to to speed up your script/spec calls by running script/spec_server in a separate terminal window, then adding the additional -X parameter to your spec calls.
Why is rspec so slow? because it loads all the environement, loads fixtures and all that jazz.
Is there a way to speed up Rails' initial load you could try using mocks instead of relying on the database, this is actually correct for unit testing and will definitly speed up your unit tests. Additionnaly using the spec server as mentionned by #Scott Matthewman can help, same with the autotest from zentest mentionned by #Marc-Andre Lafortune
Is there a way to single out the part of my Rails app I need (e.g. ActiveRecord stuff only) so it doesn't load absolutely everything to run a few tests? what about this
rake test:recent
I am not sure how the rspec task integrate with this but you could definitely use the test:recent task as a template to do the same with rspec tests if the.
rake test:rspec:recent
doesn't exist yet
because it loads all the environement, loads fixtures and all that jazz.
The real culprit is if you run it using rake spec, it runs the db:test:prepare task.
This task drops your entire test database and re-creates it from scratch. This seems ridiculous to me, but that's what it does (the same thing happens when you run rake:test:units etc).
You can easily work around this using the spec application which rspec installs as part of the rspec gem.
Like this:
cd railsapp
spec spec # run all specs without rebuilding the whole damn database
spec spec/models # run model specs only
cd spec
spec controllers/user* # run specs for controllers that start with user
I think the "zen" experience you're looking for is to run spec_server and autospec in the background, with the result being near-instant tests when you save a file.
However, I'm having problems getting these two programs to communicate.
I found an explanation here:
I've noticed that autotest doesn't send commands to the spec_server.
Instead it reloads the entire Rails environment and your application's
plugins everytime it executes. This causes autotest to run
significantly slower than script server, because when you run the
script/spec command the specs are sent to the spec_server which
already has your Rails environment fired up and ready to go. If you
happen to install a new plugin or something like that, then you'll
have to restart the spec_server.
But, how do we fix this issue? I'm guessing it would involve downloading ZenTest and changing code for the autotest program, but don't have time to try it out right now.
Are you running this over Rails? If so, it's not RSpec's initialization that's slow, it's Rails'. Rails has to initialize the entire codebase and yours before running the specs. Well, it doesn't have to, but it does. RSpec runs pretty fast for me under my small non-rails projects.
Running tests can be really slow because the whole rails environment has to load (try script/console) and only then can all tests run. You should use autotest which keeps the environment loaded and will check which files you edit. When you edit and save a file, only the tests that depend on these will run automatically and quickly.
If you're using a Mac I recommend using Rspactor over autotest as it uses a lot fewer resources for polling changed files than autotest. There is both a full Cocoa version
RSpactor.app
or the gem version that I maintain at Github
sudo gem install pelle-rspactor
While these don't speed up individual rspec tests, they feel much faster as they auto run the affected spec's within a second of you hitting save.
As of rspec-rails-1.2.7, spec_server is deprecated in favor of the spork gem.
The main reason is that require takes forever on windows, for some reason.
Tips for speedup:
spork now works with windows, I believe.
You can try "faster_require" which caches locations:
http://github.com/rdp/faster_require
GL.
-rp
If you are on a Windows environment then there is probably little you can do as Rails seems to startup really slowly under Windows. I had the same experience on Windows and had to move my setup to a Linux VM to make it really zippy (I was also using autotest).
