Making a Task Group Parameter Optional – Azure DevOps Pipelines

Task groups are really useful to share common actions with multiple build or release pipelines in Azure DevOps (VSTS). You can group multiple tasks ang create a task group forma build or release definition. then these task groups can be utilized in other build or release definitions in a given team project. Parameters in a task group help to pass values from build or release definition to the tasks in the task group. You can add a default value for these parameters or have to provide value from the build or release definition that is using the task group. Making a task group parameter optional is not straight forward and you need some do work around to get it working. Let’s look at how we can make a parameter optional for a task group in Azure DevOps pipelines.

Using Unified Agent for Executing Automated Tests Without Installing Visual Studio in Test Client–Azure DevOps/VSTS

As described in the post “Running UI Tests with Unified Agent” you can setup unified agent (same agent used for build/deployment in Azure DevOps/VSTS), in an application pool or in a deployment group to execute functional UI tests. The unified agent is really useful as it does not require to setup separate test agent using winRM based Deploy Test Agent task which is required if Run Functional Tests task is used for automated test execution.With unified agent you can use Visual Studio Test task, which is capable of running Selenium based UI tests as well, in addition to Coded UI tests. There was a dependency that you needed to have Visual Studio installed in the test client machine to get the Visual Studio Test task as it is packaged with Visual Studio. However, thanks to the NuGet package “Microsoft Test Platform”  you no longer need to install full Visual Studio in your test client machine to execute automated tests, with unified agent using Visual Studio Test task. Let’s look at how to use “Microsoft Test Platform”  and Visual Studio Test task in a test client using Azure DevOps Release Management.

Getting Content of a File in VSTS Git Repo

GItHub has a easy way to get raw contents of a file by clicking on Raw button for any code file in GitHub, where it will redirect to url starting with ‘https://raw.githubusercontent.com/’. For example the PowerShell script here can be viewed as raw content or retrieved programmatically using PowerShell using Invoke-WebRequest with url  https://raw.githubusercontent.com/chamindac/VSTS_PS_Utils/master/CreateAzureWebApp/CreateAzureWebApp.ps1. Let’s look at possibility of retrieving raw content of a file in VSTS Git repo via VSTS REST API.

Check if a Build Definition Exists for a Given Repo in VSTS/TFS

In scenarios where you have many teams working in the same team project, you might have multiple TFS Git repos within a single team project. When you want to create a build definition for a given repo, you might be wondering what if there is a build definition already exists for the repo. Opening each build definition to find that out is a waste of time. Let’s look at a small utility script that can give you the information quickly using VSTS/TFS REST API.

Values of repositoryType Parameter in VSTS REST API

VSTS REST API is really useful in achieving automations in many aspects of the software development process, and it can be used to write some handy utilities to obtain information quickly with appealing formats. However, sometimes you have to bit struggle to find out which are the correct values to pass for some parameters expected by VSTS REST API, where the documentation does not provide much of a valid information. One such parameter is ‘repositoryType’ in documentation found here for listing build definitions, which does not give any information what are the expected values for the parameter.Documentation here gives some hint on what could be the values but does not have information for REST API expected values.
