Hacking on Sky

Building

• Follow the setup & build instructions for Mojo
• Build sky with ninja, e.g. ninja -C out/Debug sky for a debug build.

If you want to build release, run the following commands:

• gn gen out/Release --args="is_debug=false"
• ninja -C out/Release sky

Running applications

• ./sky/tools/skydb [url]

  • You should see a (skydb) prompt
  • Type help to see the list of available commands
  • Note: skydb is currently hard-coded to use //out/Debug

• ./sky/tools/test_sky --debug

  • This runs the tests against //out/Debug. If you want to run against //out/Release, omit the --debug flag.

Running tests manually

• sky/tools/run_sky_httpd
• out/Debug/mojo_shell --args-for="mojo:native_viewport_service --use-headless-config" --content-handlers=text/html,mojo:sky_viewer --url-mappings=mojo:window_manager=mojo:sky_tester mojo:window_manager
• The sky_tester should print #READY when ready
• Type the URL you wish to run, for example http://127.0.0.1:8000/lowlevel/text.html, and press the enter key
• The harness should print the results of the test. You can then type another URL.

Writing tests

• Import resources/mocha.html and resources/chai.html
• Write tests in mocha format and use chai asserts:

describe('My pretty test of my subject', function() {
  var subject = new MySubject();

  it('should be pretty', function() {
    assert.ok(subject.isPretty);
  });
});
