Output logs even in the case of success

[AbhishekMarda]

Currently I'm running MSTest through Azure Pipelines using a VSTest@3 task. I observe that the test output is only done in the case of a failure, but omitted completely in the case of a success. Is there a way to output the logs for a successful tests too?

And is there a way to get the live output of a test instead of only at the end?

Yes, dotnet test --logger:"console;verbosity=detailed".

 dotnet test --logger:"console;verbosity=detailed" -tl:false

Not yet, there is this env variable: VSTEST_EXPERIMENTAL_FORWARD_OUTPUT_FEATURE=1 which will forward the output from the process, but it depends on the test framework whether or not the output will reach console. In MSTest at least there is no way to suppress capturing the managed (via Console.Write or Console.WriteLine), so only native output would reach that forwarding.

The ability to disable capturing output was added MSTest and will be released in 3.4.0 microsoft/testfx#349
