Failing without specifying configuration and platform on nunit command line?

[Jeff Hoover]

Hi.
I just started with Giles and I'm struggling a little.

I made a toy solution in 2012 with a failing test and made sure the test ran. Then I ran Giles like this:

giles -s C:\Users\Jeff\Documents\giles_test\giles_test\giles_test.sln

and hit R and no matter what, I got something like:

Build complete in 1.1499568 seconds. Result: Failure
Test run completed in 1.0722951 seconds

So I built Giles and debugged it in 2012 and found that in the Run() method, it was executing:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe c:\users\jeff\giles\giles\giles.sln

so I ran that command in a command prompt and got:

...Project "c:\users\jeff\giles\giles\giles.sln" on node 1 (default targets).
c:\users\jeff\giles\giles\giles.sln.metaproj : error MSB4126: The specified solution configuration "Debug|BNB" is invalid. Please specify a valid solution configuration using the Configuration and Platform properties (e.g. MSBuild.exe Solution.sln /p:Configuration=Debug /p:Platform="Any CPU") or leave those properties blank to use the default solution configuration. [c:\users\jeff\giles\giles\giles.sln]
Done Building Project "c:\users\jeff\giles\giles\giles.sln" (default targets) -
- FAILED.

so I changed Run() as follows:

//            var result = CommandProcessExecutor.Execute(settings.MsBuild, "\"" + config.SolutionPath + "\"");
            var executeArguments = "\"" + config.SolutionPath + "\"" + " /p:Configuration=Debug /p:Platform=\"Any CPU\"";
            var result = CommandProcessExecutor.Execute(settings.MsBuild, executeArguments);

Then I built and ran it and, sure enough, I got:

======= NUNIT TEST RUNNER RESULTS =======
Passed: 0, Failed: 1, Ignored: 0

which is what I expected for my toy solution.

What am I doing wrong?

Thanks,
Jeff
