Testing

Testing

Testing Tracks is fairly simple. For its tests 3 different technologies are used:

• Ruby unit tests (in $RAILS_ROOT/test)
• RSpec (in $RAILS_ROOT/spec)
• Cucumber (in $RAILS_ROOT/features)

Setup

The tests make use of some gems which need to be installed first

Install required gems with

bundle install

Running the Rails test suite

Assuming you’ve already checked out the source code using git, change to the root directory of the project ($RAILS_ROOT) and run

rake test

If it completes successfully 0 failures, you’re good to go!

Running the RSpec test suite

To run the Rspec tests run

rake spec

Running the cucumber test suite

For integration testing Tracks uses cucumber. For those features that require javscript/ajax, Tracks uses Selenium on Webrat

To run the features excluding the selenium features and the work-in-progress (wip) features, run

rake cucumber

To run the features that make use of Selenium on Webrat, run

rake cucumber:selenium

To run the features that are work in progress run these:

rake cucumber:selenium_wip
rake cucumber:wip

To run a feature by hand run these. Please note the different RAILS_ENV value and the -p usage for selenium:

RAILS_ENV=cucumber cucumber features/my_feature.feature
RAILS_ENV=selenium cucumber -p selenium features/my_feature.feature

If you encounter problems runnig selenium tests, look at the Problems with cucumber selenium tests section below.

Running the tests headless

All tests will run on a headless setup except for the selenium tests. They will need a webbrowser which will need a running X-server.

You can solve this by running a virtual framebuffer X server. In Fedora, you need to install the packages xorg-x11-server-Xvfb and xorg-x11-apps

Xvfb :99 -ac -screen 0 1024x768x16 &

DISPLAY=:99.0 rake cucumber:selenium

killall Xvfb

Running the old browser-based Selenium test suite

We are migrating from the selenium test suite in the browser to cucumber and selenium on webrat. To run the selenium scripts that are not yet migrated, the following still applies:

To run the suite simply run Tracks in the test environment:

  script/server -e test

in a separate command window, then run

  rake test:acceptance

and Firefox will pop up and run the suite. If this does not work, you can run the suite manually by launching the server in test mode with the command above, and navigating to

http://localhost:3000/selenium/ in your browser of choice.

Problems with cucumber selenium tests

Tests doesn’t start

Firefox 3.x is required to run the selenium tests properly. It’s also recommanded to use an english version, to avoid problems due to the locale.
You can get an old version of firefox here.

Sqlite3 Lock exceptions

In the default settings sqlite locks the db immediately. This behavior can cause problems with the fast executing online tests. Add a timeout to the database.yml configuration file to avoid these errors.
For example:

test: &TEST
    adapter: sqlite3
    database: db/test.db
    timeout: 10000
