ekatek ef13ed9926 use selftest to run tests against galaxy
UX Changes:
  - Added a `--galaxy` option to selftest to run tests against galaxy.
    Self-test will NOT run those tests without this option. Self-test will not run any
    other tests WITH this option.

    The motivation here is two-fold:
     - We want to make it easy to use self-test to test Galaxy without running a bunch
       of extra tests. At least, we want this right now, while Galaxy is still in development.

     - Galaxy is currently pretty unstable&slow; we don't want to run our regular test suite against
       Galaxy all the time and slow down the tool development process. Additionally, the environment
       variables required by Galaxy are a pain to set.

    This is a TEMPORARY situation. Eventually, we will want to either merge the two tests together
    (especially once we rotate out Mother...) or we will have a separate unrelated Galaxy test suite
    and move a lot of this stuff here. With time, it will also become more obvious what a better default
    (run Galaxy tests always/run Galaxy tests never/run non-Galaxy-specific tests against Galaxy) is.

    The changes should be pretty self-contained.

 - Added some number of environment variables to use with --galaxy tests. This is a bit complicated
   and will be documented in
     https://mdg.hackpad.com/GalaxyECS-Admin-tasks-RTXJ5YW8pDv#:h=Testing-Galaxy-with-selftest.

Walkthrough:
    - galaxy-utls.js contains basic utils for running Galaxy tests. Use environment variables, etc.

    - galaxy.js contains the acutal test

    - simple-app is an app that responds to HTTP requests and serves some html that we can test to be running

    - minor changes to config.js to allow overriding of the domain name

    - minor changes to auth.js to allow us to automatically login as the (new) test user and use that
      login to start a DDP collection.

    - move a function out of deploy-settings.js into test-utils.js

    - some minor additions to test-utils.js

Tools testing

Running end-to-end tests happens through the Self-Test. To run the tests:

./meteor self-test <regexp>

A very-very useful environment variable to set, in case you are running on a slow machine:

# set the multiplier for time-outs
set TIMEOUT_SCALE_FACTOR=3

Writing tests

All tests are currently stored at /tools/tests/, each JS file can register a self-test. Example:

selftest.define("mongo failover", [/* tags */], function () {
  var s = new Sandbox();
  s.set('METEOR_TEST_MULTIPLE_MONGOD_REPLSET', 't');
  s.createApp("failover-test", "failover-test");
  s.cd("failover-test");

  var run = s.run("--once", "--raw-logs");
  run.waitSecs(120);
  run.match("SUCCESS\n");
  run.expectEnd();
  run.expectExit(0);
});

The example above demonstrates how to define a test, create a Sandbox, create an app from a template and run the Meteor commands.

Templates for apps and packages are kept in /tools/tests, too.

Testing with Phantom/Browserstack

The sandbox has a testWithAllClients method that runs the clients like Phantom or Browserstack pointed to the page of the app (localhost:3000 by default).

Tags

Tags are arbitrary. To make tags do anything, you should edit the selftest.js code.

Examples of some tags that exist today:

  • slow - the test is skipped, unless the --slow flag is passed
  • windows - the test is not run unless on Windows
  • net - the test is talking to external Internet services, thus requires an Internet connection to run

There are others.

Self-test gotchas

  • The docs for self-test is reading the code of self-test
  • run.forbid(regexp) forbids the regexp from the entire output, not from the point it was called. It happens, because the output is matched asynchronously.
