How to run tests on many machines in parallel

Question

I use MSTEST and write tests in c#. I have some tests in my project at a test class. I have test settings file with: parallelTestCount='0'

There is a selenium grid hub installed on my machine.

There is a node installed on my machine and there is another node installed on another machine.

I run the test from cmd as:

MSTest.exe /testcontainr:C:/MyProject.dll /testsettings:C:MyParallelSettings.testsettings

Then some tests start running in parallel at one node on one machine. But only after the tests end running, the other tests start running at the other node on the second machine in parallel.

How can I run all the test run in parallel on some other machines at the same time?

Answer 1

Using start will launch each executable within split seconds from each other, without the one having to wait for the other to complete, so simply run the commands in batch:

start "" "MSTest.exe" /testcontainr:C:/MyProject.dll /testsettings:C:MyParallelSettings.testsettings
start "" "MSTest.exe" etc.
start "" "MSTest.exe" etc...
