MSTest Workflow Activity Creates Long Directory Names

Question

We have a TFS gated check-in which uses MSTest workflow activity for running our unit tests. We came across some issues recently due to the result folder that MSTest activity creates being too long so some of our unit tests are failing now because of that. It looks it uses a patter like <user>_<machine_name> <date> <time>_<platform>_<config> so we see very lengthy directory names like "tfsbuild_machine123 2015-09-10 10_00_00_Any CPU_Debug" . I did some digging into the workflow and its options but couldn't identify where this pattern is coming from. I appreciate if someone can please point me to where this is coming from and how I can change it so we get more room for our unit testing.

Answer 1

I assume that you're referring to test part in the Build Summary page. Like:

As far as I know that the Summary part in the Build Summary page actually is a SummaryFactory type which drives from IBuildDetailFactory, it is not defined in the TFS build process template. The SummaryFactory class contains some functions like CreateSections and CreateNodes which are used to create nodes with on the Summary page, for example, a hyperlink with the format <user>_<machine_name> <date> <time>_<platform>_<config> . However, the SummaryFactory.cs is an internal class so you can't use it in your own program, nor to customize the test hyperlink format.

For your issue, I still would like to check the detailed error message to see what's wrong with it.
