cake: The MSTest tool doesn't pick up the mstest.exe from Visual Studio 2017

What You Are Seeing?

I run the unit tests like this:

MSTest("./src/**/bin/" + configuration + "/*.Tests.dll");

I get the following error when running the build script:

An error occurred when executing task 'Run-Unit-Tests'.
Error: MSTest: Could not locate executable.

What is Expected?

I expect my unit tests to run.

What version of Cake are you using?

0.17

Are you running on a 32 or 64 bit system?

64 bit

What environment are you running on? Windows? Linux? Mac?

Windows 10

Are you running on a CI Server? If so, which one?

No, just building on my local machine.

How Did You Get This To Happen? (Steps to Reproduce)

Run a build with unit tests on a machine with only Visual Studio 2017 (Community Edition).

Looking forward to the fix. This is the workaround I’ve been using:

// https://github.com/cake-build/cake/issues/1522
VSTestSettings FixToolPath(VSTestSettings settings)
{
    #tool vswhere
    settings.ToolPath =
        VSWhereLatest(new VSWhereLatestSettings { Requires = "Microsoft.VisualStudio.PackageGroup.TestTools.Core" })
        .CombineWithFilePath(File(@"Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe"));
    return settings;
}

Then just wrap your settings:

VSTest("**/*.Tests.dll", FixToolPath(new VSTestSettings { Foo = 42 }))

(See https://github.com/Microsoft/vswhere/wiki/Find-VSTest.)

I had the same issue - as @phillipsj already mentioned, the ToolPath did the trick (even it is not super “clean”)

MSTest(pathPattern, new MSTestSettings() { ....
                                 ToolPath = @"C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\MSTest.exe" });
