Visual Studio Online source path

Question

How do I programmatically determine the path of my source code when running unit tests in Visual Studio Online's hosted build infrastructure.

Why do I want to know this? I want an integration test to run redis-server.exe from the Redis-64 NuGet package so that it can run tests that use Redis.

FWIW, here are the environment variables from the Visual Studio Online build server:

Answer 1

TF_BUILD_SOURCESDIRECTORY works as documented here in pre-post test scripts. They are not available in the VSTestRunner activity.

So you should prepare your application using a pre-test script, where you can grab stuff from known build places.

NOTE The environment variables are available only with later build templates, like TfvcTemplate.12.xaml and GitTemplate.12.xaml. The DefaultTemplate.11.xaml shows only TF_BUILD.

Answer 2

Type C:\a\src into your source code. At least the path is always the same, but I hope there's a better answer.
