Automatic creation of bugs in Azure DevOps Server

An important part of running automated test cases is to monitor, inspect, and react to the results. This is best accomplished in the test management and bug tracking system that we use for our daily work.

In this article, we will review three different scenarios on how to trigger and create/update bugs in the Azure DevOps Server, formally known as Visual Studio Team Services (VSTS) or Team Foundation Server (TFS), based on the results of the test cases running in Leapwork.

 

Trigger schedules from API and create bugs in Azure DevOps Server

Integrating Leapwork with any third-party system through the REST API can be done in a few simple steps. This enables us to easily set up the automatic creation or updating of bugs in Azure DevOps Server when test automation cases fail in Leapwork.

 

As part of the integration, we have a Windows Powershell script that runs a pre-defined Leapwork run list, polls for the results until they are available, and then loops through all failed cases and creates bugs in JIRA as appropriate using API's.

The following changes are required above script:-

  • Generate an AccessKey from Leapwork Studio->Settings->Add Key.
  • Replace the generated key with Accesskey value

          $headers.Add("AccessKey","bTyGAd0alksslkals")

# Create an authorization header using a Personal Access Token.
$pat = "YOUR PERSONAL ACCESS TOKEN HERE"
  • Enter the Azure DevOps Instance URL
 $urlAlreadyExists = "https://YOURINSTANCE.visualstudio.com/DefaultCollection/YOURPROJECT/_apis/wit/wiql?api-version=1.0" 

After running the PowerShell script, the schedule will be executed and for failed flows, a bug will be logged in Azure DevOps.

Note: The script contains no error handling or logging mechanisms. It is meant to only demonstrate the core functionality of integrating Leapwork with Azure DevOps Server.

After running, cases are created in Azure DevOps Server and can be managed, for instance, through Visual Studio:

The previous script uses PATs to authorize access to Azure DevOps Server.

If we have the Controller installed on our computer, explore the previously mentioned endpoints by going to the following URL: http://localhost:9001/help/index.
