@christian-bromann/webdriverio/lib/commands/debug.js

A nodejs bindings implementation for selenium 2.0/webdriver

/**
 *
 * This command helps you to debug your integration tests. It stops the running queue and gives
 * you time to jump into the browser and check the state of your application (e.g. using the
 * dev tools). Once you are done go to the command line and press Enter.
 *
 * Make sure you increase the timeout property of your test framework your are using (e.g. Mocha
 * or Jasmine) in order to prevent the continuation due to a test timeout.
 *
 * <example>
    :debugAsync.js
    client
        .setValue('#input', 'FOO')
        .debug() // jumping into the browser and change value of #input to 'BAR'
        .getValue('#input').then(function(value) {
            console.log(value); // outputs: "BAR"
        });

    :debugSync.js
    it('should demonstrate the debug command', function () {
        browser
            .setValue('#input', 'FOO')
            .debug() // jumping into the browser and change value of #input to 'BAR'

        var value = browser.getValue('#input');
        console.log(value); // outputs: "BAR"
    });
 * </example>
