});

// send some sample data
tester.emit('data', 'randomMessage');
tester.emit('data', 12345);

Alias for setTest.

The setTest method accepts a name string and test function and stores the test function under the specified name. The test function has to return true or false.

The getTest method accepts a name string and returns the test stored under the specified name.

The delTest method accepts a name string and deletes the test stored under the specified name.

The data event is used to send the tester a new data entry with the data parameter containing the data.

The result event is fired when the tests are finished. It returns a result containing a tests array that contains all passed tests and a data field containing the data.
