Interacting with a native application

Now that we have covered how to interact with an operating system and used screenshot based testing capabilities of Sakuli, we can move on how to utilize one or multiple applications. All features are incorporated in the ThenableApplication Interface.

Open an application

To open an application, you enter the path to the application or respectively the application name, if you already added it to your PATH environment variable. If your path contains spaces, you have to escape them with \\ because white spaces are reserved for parameter separation.

// path to excel 'C:\\path to excel \excel.exe'
const excel = new Application("C:\\path\\ to\\ excel\excel.exe");

// open browser with parameters
const chromium = new Application("chromium-browser --incognito --proxy-server=localhost:1234");

// path to chrome is e.g. 'C:\\Program\\ Files\google-chrome\chrome.exe'
const chrome = new Application("C:\\Program\\ Files\google-chrome\chrome.exe --incognito");

After creating an application with new Application(), it is necessary to call open() for Sakuli to start it.

With setSleepTime(seconds) you can set the waiting time after opening an application. This is particularly useful for larger applications that have an initial loading time.

const calc = new Application("gnome-calculator");
//sleepTime of 1 second
await calc.setSleepTime(1)

Closing an application

You can either use close() or kill(). close() sends a SIGTERM signal and kill() a SIGKILL signal to end the process.

await calc = new Application('gnome-calculator').open();

await calc.close();
await calc.kill();

//throws an exception if ending the process fails
await calc.close(false);
await calc.kill(false);

Combining with Region

Currently (Sakuli v2.3.0) it is not possible to get the region from the application or the focused window. Therefore the following methods will return the desktop instead.

const calc = new Application('gnome-calculator');
