Usage of moles.runner.exe with MSTest.exe as the test runner

When I execute moles.runner.exe, providing MSTest.exe as the runner, I'm seeing an error.

Here is the command line:

moles.runner.exe MyAssembly.dll /r:MSTest.exe /args:/resultsfile:output.trx /args:/testcontainer:MyAssembly.dll

Here is the output:

Microsoft Moles Runner v0.94.51023.0 -- http://research.microsoft.com/moles -- .NET v4.0.30319

Invalid switch "MyAssembly.dll"
For switch syntax, type "MSTest /help"

When I execute moles.runner.exe with /d (Diagnostic mode), it shows this:

r>MSTest.exe MyAss开发者_运维问答embly.dll /resultsfile:output.trx /testcontainer:MyAssembly.dll

How can moles.runner.exe be directed to not pass the assembly name as the first argument to the test runner?

The test container should not be specified to moles.runner.exe with /args, i.e.:

/args:/testcontainer:MyAssembly.dll

Instead, it should be specified with /afs (RunnerAssemblyFormatString) as follows:

/afs:"/testcontainer:{0}"

That will instruct moles.runner.exe to output the test assembly within the MSTest.exe-required /testcontainer argument.
