Use QtWebDriver to run your application

Testing a plain html or qml application

Then using the prebuilt Webdriver out of the box is enough.

• Start WebDriver

$ ./WebDriver --verbose

• Use Selenium to open the application

    WebDriver driver = new RemoteWebDriver(new URL("http://192.168.24.1:9517"), capabilities);
    driver.get("http://example.com/example.html");
    // or
    driver.get("http://example.com/example.qml");
    System.out.println("Plain HTML or QML page source:\n" + driver.getPageSource());

Testing a native or hybrid application

There are 2 ways:

Option 1: WebDriver attaches to the running application

• Add the QtWebDriver headers and librairies in the application build environment
• In the application code, include the headers: Headers.h
• Call the wd_setup(argc, argv) function with the parameters you want (See ful argument list: Command Line Switches)
• Rebuild an run your application, thi swill start QtWebDriver
• Use Selenium to open the application

    WebDriver driver = new RemoteWebDriver(new URL("http://192.168.24.1:9517"), capabilities);
    System.out.println("Native page source:\n" + driver.getPageSource());
    WebElement elt = driver.findElement(By.xpath("//QTextEdit"));

• Example 1: A basic example of an application using QtWebDriver main.cc
• Example 2: Add QtWebDriver support to Qt-5.5//Src/qtbase/examples/widgets/mainwindows/mainwindow

Pros:

• Easy to setup
• The application lifecylce is not impacted. It starts as it should, not on request of WebDriver

Cons:

• Need to modify the application code in order to run webdriver. But a such additional code can be flagged for test build only.

Option 2: WebDriver creates the application

• Modify main.cc to register your application:

int wd_samples_setup(webdriver::ViewCreator* widgetCreator,
    webdriver::ViewCreator* webCreator,
    webdriver::ViewCreator* qmlCreator,
    CommandLine &cmd_line)
{
    if(widgetCreator != NULL)
    {
        widgetCreator->RegisterViewClass<MyWidgetClass>("MyWidgetClass");
...

(See Samples.h )

• Rebuild Webdriver and rerun WebDriver

$ ./build.sh
$ out/dist/desktop/release/bin/WebDriver --verbose

• Use Selenium to make WebDriver create you application:

    WebDriver driver = new RemoteWebDriver(new URL("http://192.168.24.1:9517"), capabilities);
    // This will trigger creation of a MyWidgetClass
    wd.get("qtwidget://MyWidgetClass");
    System.out.println("Native page source:\n" + driver.getPageSource());
    WebElement elt = driver.findElement(By.xpath("//QTextEdit"));

Pros:

• No need to modify the application code

Cons:

• Need to modify the WebDriver build to add the application classes. It must be possible to build the application using the WebDriver build system
• The application lifecylce can be impacted. WebDriver will call the default constructor of the application class, not knowing about any parameters or preconditions.
