In some cases, you may experience compatibility issues when Google releases new versions of the Google Chrome browser. This can prevent your Automation tests from running correctly.

Users affected by this issue generally see a failed to create ChromeDriver error when attempting to execute test cases in any run mode, including via Apache Ant in conjunction with any continuous integration solution.

See the example error message below.

To resolve this issue, you should update your ChromeDriver version.

Disabling Auto-Update

Step 1: Disable Automation’s auto-update feature (ChromeDriver versioning) by entering the provar.ini file at the installed location. Typically, this is added at the end of the script.

-Dcom.provar.chromedriver.versioningSupported=false

Example (click to enlarge):

For Apache Ant execution, the user can use the following commands to set this variable:

For Windows Set ANT_OPTS to:

-Dcom.provar.chromedriver.versioningSupported=false

For Linux or Mac Export ANT_OPTS to:

-Dcom.provar.chromedriver.versioningSupported=false

Step 2: Delete any ChromeDriver folder inside the user home folder. {UserHome}/Provar/.chromeDriver.

Note: Ensure that there are no ChromeDriver processes running. Kill the processes if there are any.

Step 3: Execute the test case to launch the browser session.

What should I do if I don’t have permissions to update my provar.ini file?
