Configuration Steps
Each web browser uses its own WebDriver protocol implementation. As such, when you plan your automation projects via the WebDriver protocol, you need require the corresponding browser webdriver application on the machine, and have it configured as explained in the next topics. Below you find the requirements and steps to take in order to use the WebDriver protocol:
|
Web Browser |
Webdriver Requirements |
|---|---|
|
Chrome |
|
|
Firefox |
|
|
Edge |
|
- Download the Webdriver corresponding to the browser you want to use.
- Install the downloaded Webdriver in a location of your choice, such as
C:\webdriver\Chrome. - In the Windows Start Menu, find and open the Edit the system environment variables entry. The System Properties window is displayed.
- Click the Environment Variables... button at the bottom of the page. The Environment Variables window is displayed.
- Select the Path variable either from the User variables or System variables section and click the Edit... button. The Edit environment variable window is displayed.
- Click the Browse... button and select the folder where you installed the corresponding Webdriver executable. In our case this is
C:\webdriver\Chrome. - Click the OK button on all previously opened windows to save the changes. The Webdriver protocol is now installed.
-
Restart the Robot Service for the changes to take effect. You are now ready to use the Webdriver protocol in your automation projects.
Interacting with a browser via the Webdriver protocol is possible inside an Open Browser or Attach Browser container. A couple of properties need to be configured, as follows:
- CommunicationMethod - WebDriver
- BrowserType - Chrome, Firefox or Edge
-
Hidden - True
Please note that, for headless browser automation, activities relying on hardware events (such as Click or Type Into) must be configured to use the SimulateClick or SimulateType properties, or the Send Window Messages property.
It is recommended to use the Close Tab activity to close all open tabs. All you need to do is place it inside the Open Browser container which uses the WebDriver protocol at the end of the sequence. The corresponding webdriver application and processes are closed.
<HTML> tag. This way the corresponding webdriver process is also closed along with the browser session.
<HTML> tags you can use with the Close Application activity:
<html app='firefox.exe' />- to close Firefox<html app='chrome.exe' />- to close Chrome<html app='msedge.exe' />- to close Edge
You might, however, want to tweak the selector for the Close Application activity to specifically target the browser session you are automating, because this method closes the first browser it finds which matches the selector.
<WND> tag, the browser session is still closed, but the webdriver process remains active.
