TFS Build Agent Fail on Get Source After Upgrade

TFS on premise requires you to keep your TFS updated as almost in every quarter a new update to the TFS is released as well as a new version every year. For this you might have to do TFS Upgrades. If you have upgraded from TFS 2015 to TFS 2018 you have to remove the version 1.xx build agents and configure version 2.xx build agents. Your existing build might encounter workspace issues and may not be able to get sources downloaded to build, in the build agents after the upgrade of agents done. Let’s look at how we can get this issue resolved.

There may be few version gaps when you try to upgrade your TFS. Let’s discuss a problem with SQL server, faced while upgrading from TFS 2015.2 to TFS 2018, and how can it be fixed without getting into deeper troubles. This upgrade was done after a pre production trial using a clone of the TFS 2015.2, and no issues faced during TFS2015.2 from to TFS 2018 in the trial steps, which were exactly followed in production, except for clone TFS 2015.2 of course.

Running UI Tests with Unified Agent

You needed to setup dedicated machines for testing when using Run Functional Tests and you had to execute, Deploy Test Agent step and Copy Files step as prerequisites. With the introduction of unified agent enabling build, deployment and testing using same agent, now it is possible to setup pool of machines as Test clients to cater multiple project needs. You can even deploy and test using the same agent if you wish to do so.  Unified agent support is available to run tests as multi-machine distributed execution. You do not require to execute copy files task as artifacts downloaded by the agent can be used for running tests. Let’s look at how to prepare a unified agent for running UI tests.
