Whenever Jenkins is restarted, any updates\additions to the VSTEST settings on the Global Tool Configuration page under the VSTest Installations are lost and it returns to the DEFAULT. I manually have to re-add configs for VSTest 14 and 15.
I've created Pull Request #18 to solve this issue.
I suggest to increase bug priority
Should be fixed in the upcoming release
Great news, thanks!
1.0.8 should appear in the update center in the near future
