You can run single test using Rails 5 test runner by specifying the file and the linenumber like the following:
rails test path/to/test:55
In RubyMine, you can run single test from context menu on a test you want to run. However, since it is not via the above test runner, it does not use a spring preloader and takes long to launch a test.
I have tried to create new Run/Debug configuration to run test via spring, but I am still not sure how to do it.
Please let me know how to run single test via Rail5 test runner?

Sometimes I have a broken test on CircleCI, where the error can't be replicated locally. Instead of waiting for the whole suite to run, I'd like to run that one test individually. (I know I can ssh in, but that's time-consuming and running it that way wouldn't exactly replicate the usual automated test sequence.)
My aim is to make a temporary config commit to run just one test (ideally just a test method, but the whole class would be fine too). I can think of two possible solutions: (A) edit app.rake to make the default rake task run a single test; or (B) edit circle.yml to run just the one test from command-line using rake test. Any clue on either of these?
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 teaching myself Ruby On Rails with Michael Hartl's Book. When it uncovered the use of seeds.rb file, I tested within Development Environment, it Failed. When set to Test Environment, It Succeeded. Why? When will I need to change the environment again for successful tests?
When you say I tested within Development Environment, it Failed., you are not running automated tests. You ran the rake db:seed script against the development database. The same task can be run against the test environment with rake db:seed RAILS_ENV=test. Again, this is not an automated test.
There are many reasons why rake db:seed run against the development environment failed in your case. The specific reason could be identified based on the error message.
development environment is one where you work on a day to day basis, adding/changing functionality by making code changes. By default, most scripts assume that you are working with development environment.
test environment is the environment against which the automated tests are run. In the case of rails tutorial, the automated tests are written in the files under test folder. When automated tests are run on a rails application - with rake test or some other way - the test environment is used to run these tests against. The test database gets cleaned up before running the tests to ensure the tests are run starting with a blank state.
Hope this clarifies.
So I do testing rspec+capybara on localhost, but if I wanted to test on staging server(linux), is it possible to use capybara?
I'm guessing testing with selenium will not work on staging server.
I would like to test frontend(mostly js stuff) on staging, any recommendation would be great.
I use Rails 3.
Checkout the headless gem - From the author
I created it so I can run Selenium tests in Cucumber without any shell scripting. Even more, you can go headless only when you run tests against Selenium.
I'd imagine it would would with rspec as well.
We have a few test cases automated with selenium & capybara during the application development. They all works well when we run it from within the application using rake spec command.
Now in order for the QA team to run these, we don't want to setup the rails environment in their computer. Is there a solution for this?
I am using the following gems,
capybara
selenium
rspec
Any input or suggestion will be really helpful.
Thanks in advance....
