How to run node-webkit's test cases

How do we test with Mocha

In folder automatic_test, every subdirectory has a file called mocha_test.js. In mocha_test.js, there are test cases writed using mocha. Finally we load these test case and run them in index.html.

How to write test case for node-webkit

Mocha is easy to use, you can directly wirte mocha code in mocha_test.js. But if you have a simple app and want to ues it, there are some traps.

Since you need to spawn a new process for the app, but there would be problem using the communication method of node.js's child_process modoule. So you need to use other method for the data transporting like using socket.

In node-webkit testing system, we have implement a simple module nw_test_app for the job. How to use it:

mocha_test.js:

var child = app_test.createChildProcess({
  execPath: process.execPath,
  appPath: 'path_to_app',
  end: function(data, app) {
    if (data.ok) {
      done();
    } else {
      done('error');
    }
  }
});

app:

var client = require('nw_test_app').createClient({
  argv: gui.App.argv,
  data: {ok : true},
});
