test_runner: run xunit with parameters containing spaces fails

[joelwilson]

Task:

namespace :tests do
  test_runner :unit do |tests|
    tests.files = FileList['MyProject.Tests/bin/**/*MyProject.Tests.dll']
    tests.exe = 'packages/xunit.runner.console.2.0.0/tools/xunit.console.exe'
    tests.add_parameter '-parallel all'
  end
end

Error:

$ rake test
(in c:/Users/jwilson/Code/MyProject)

Tests run without errors if I specify a parameter containing no spaces such as -nologo.

-parallel all are two parameters, not one, as seem from the operating system.

Thanks for the quick reply! What you say makes sense and by splitting the parameter into two, it works. It would be nice though if albacore could somehow handle arguments like these so we can avoid creating two add_parameter calls for one logical key/value parameter.

We'd have to implement parsers for every exe you'd ever put inside the exe property to do that. Or somehow write a C#/IL-interpreter so we can know what are stand-alone parameters and which ones are together.
