Test Builder not working correctly

If you’ve recently installed Provar and are having trouble using the Test Builder (e.g. after right-clicking on objects, the Add to test case option doesn’t display), it can be related to a Chrome browser compatibility issue.

You can quickly check to see if your ChromeDriver is causing the issue by looking at the top right-hand corner of your Chrome browser. If you don’t see a small Provar icon (which indicates that you have the Provar extension working correctly), you can take the steps mentioned below to fix this issue.

This issue occurs more commonly in work environments with advanced network security restrictions. To fix this issue, you will need to manually download the most up-to-date version of the Provar extension. Here’s how!

How to get the Extension ID?


To get the Extension ID, please see the Chrome web store link for the given Provar release. This link is available against the relevant Provar release in the Provar Success Portal. The Extension ID is a 32-character string at the end of the Chrome web store link.

Steps for Test Builder to work correctly


  1. Contact your system administrator to verify that the Provar Chrome extension has been white-listed.
  2. Exit the Provar desktop application.
  3. Ensure that there are no ChromeDrivers running on your machine. To verify, open the Task Manager/Activity Monitor and end tasks associated with chromedriver.exe.
  4. Delete the Provar extension from all Chrome browsers on your local machine. You can do this by opening Chrome, click the “more” icon in the upper-right (three vertical dots), click More Tools, Extensions and then select Remove.
  5. Go to the location where Provar is installed (C:Program FilesProvar on Windows).
  6. Open provar.ini file in a text editor with administrator privileges.
  7. Add this line to the end of the provar.ini file in Provar installation directory: -Dcom.provar.tooling.chrome.extensionId=[ahcaopmmbcfojipcghpceejhghaepadp]
  8. Go to your Provar Workspace folder (Usually USER_HOME%/Provar/Workspaces/PROJECT_NAME/).
  9. Delete .chromeProfiles folder from this directory (may require admin privileges).
  10. Launch Provar as an administrator (this may require administrator approval or intervention) and open any test case in the Test Builder.
  11. Open a new tab in Chrome and add the latest Provar extension in the browser. You can download this from the Chrome web store link for the given Provar release, which can be found in the Provar Success Portal.
  12. Close this window, the Test Builder and Provar desktop.
  13. Go to Provar’s workspace folder (same as step 5)/.chromeProfiles.
  14. Copy the profile0 folder and paste it in this folder for however many additional profile folders are present. Override each profile folder with profile0 by renaming the copies profile1, profile2, etc.
  15. Launch Provar (not as the system administrator) and open this same workspace.
  16. Open any test case using Test Builder and you should see the Provar extension icon at the top right of the Chrome browser.
