How to run node webkit's test cases - Hosting-Site/node-webkit GitHub Wiki

• node-webkit didn't ship third party node modules required for testing, you need to install them.
• We use nw-gyp to build native modules.
• We have test cases that need a http server. And we have set up a simple nodejs server with port 8123 and 8124 opened. The http server document root is tests/server. You can add ports in tests/server/server.js

So please run this:

$ npm install -g nw-gyp
$ cd src/content/nw/tests
$ npm install -d

The test suits is indeed a node-webkit app, so use node-webkit to run it:

$ /path-to-node-webkit src/content/nw/tests

$ /path-to-node-webkit src/content/nw/tests --help

  Usage: nw-test [options]

  Options:

    -h, --help             output usage information
    -V, --version          output the version number
    -S, --silent           hide the browser window and quit when done (run silently)
    -R, --reporter <name>  specify the reporter to use
    -g, --grep <pattern>   only run tests matching <pattern>
    -i, --invert           inverts --grep matches
    -t, --timeout <ms>     set test-case timeout in milliseconds [2000]
    -s, --slow <ms>        "slow" test threshold in milliseconds [75]
    -b, --bail             bail after first test failure
    -A, --async-only       force all tests to take a callback (async)

Hide the browser window (run silently), and quit the app when tests are done, suitable for automatic tests system.

Output result to a file, this is usually used together with json reporter, so we can write the results of test to the file in the format of JSON.

The --reporter option allows you to specify the reporter that will be used, defaulting to html. This flag may also be used to utilize third-party reporters. For example if you npm install mocha-lcov-reporter you may then do --reporter mocha-lcov-reporter.

The --grep option when specified will trigger mocha to only run tests matching the given pattern which is internally compiled to a RegExp.

Suppose for example you have api related tests, as well as app related tests, as shown in the following snippet; One could use --grep api or --grep app to run one or the other. The same goes for any other part of a suite or test-case title, --grep users would be valid as well, or even --grep GET.

describe('api', function(){
  describe('GET /api/users', function(){
    it('respond with an array of users')
  })
})

describe('app', function(){
  describe('GET /users', function(){
    it('respond with an array of users')
  })
})

Specifies the test-case timeout, defaulting to 2 seconds. To override you may pass the timeout in milliseconds, or a value with the s suffix, ex: --timeout 2s or --timeout 2000 would be equivalent.

Specify the slow test threshold, defaulting to 75ms. Mocha uses this to highlight test-cases that are taking too long.

Only interested in the first exception? use --bail !

To make the testing automatic, we need to:

1. Write results to a file.
2. Print the results in a machine-readable format, like JSON.
3. Run tests silently and quit when done.

In node-webkit's test, we can do:

$ /path-to-node-webkit src/content/nw/tests --silent --output result.json --reporter json

Some tests like visiting html5test.com and getting its score would take too long to run for normal tasks, these tests are usually marked as long-to-run, so you can use following command to filter out them:

$ /path-to-node-webkit src/content/nw/tests --grep long-to-run -i

in test case like node-remote, we need to open a http server to be the remote site. It is automatically opened when we run tests. We use port 8123, 8124 for test. The http server document root is tests/server. We have put some resources there e.g. node_remote_test.html.

When there is a new nw release, We hope you to rebuild native modules.

We use tools/build_native_modules.py to build our native modules:

$ cd src/content/nw
$ python tools/build_native_modules.py`

Also, please update node_modules using npm install -d.
