Programmically launch TestRunner

[Chris]

Hello all,

I'd like to be able to programmatically execute all tests in an assembly as if I were using Gallio.Echo or Gallio.Icarus (basically, I just want finer grained control over what those runners offer).

It looks like I want to create and use an instance of Gallio.Runner.TestLauncher, but I can not get it to execute.  The following code:

ILogger logger = (ILogger)new RichConsoleLogger(NativeConsole.Instance);
var launcher = new TestLauncher()
{
  Logger = logger,
  ProgressMonitorProvider = NullProgressMonitorProvider.Instance
};
launcher.RuntimeSetup = new Gallio.Runtime.RuntimeSetup();
Assembly assembly = typeof(TestRunner).Assembly;
FileInfo assemblyInfo = new FileInfo(assembly.Location);
launcher.AddFilePattern(assembly.Location);
launcher.Run();

--- Produces the following Exception:

Gallio.Runtime.RuntimeException was unhandled
  Message="Could not resolve component for service type 'Gallio.Runner.Projects.ITestProjectManager' because there do not appear to be any components registered and enabled for that service type."
  Source="Gallio"

I assume this has something to do with the registry not being loaded with plugins.  What else do I have to call to set up a basic runner for one assembly?  Is there any simpler way?

Thanks,

Have you initialised the runtime? (See RuntimeBootstrap.Initialize(runtimeSetup, runtimeLogger)).

Yeah, it looks like adding the following worked:

ILogger logger = (ILogger)new RichConsoleLogger(NativeConsole.Instance);

var setup = new Gallio.Runtime.RuntimeSetup();
setup.AddPluginDirectory(@"..\GallioBundle\bin");
RuntimeBootstrap.Initialize(setup, logger);

I had to add the addPluginDirectory because the .plugin files weren't in the execution directory.

It looks like that even invoking through code, however, that it executes the test cases in some sort of isolated environment (a different process? Gallio.Host?)

Is there any way that I can get the tests to execute in same application context/process?  I want to optimize for speed and the ability to attach the debugger.

Thanks,

The option I was looking for was

launcher.TestProject.TestRunnerFactoryName = StandardTestRunnerFactoryNames.Local;

Works the way I expect now :)  Complete code snippet:

      ILogger logger = (ILogger)new RichConsoleLogger(NativeConsole.Instance);
      var setup = new Gallio.Runtime.RuntimeSetup();

      setup.AddPluginDirectory(pluginDir);
      RuntimeBootstrap.Initialize(setup, logger);

      var launcher = new TestLauncher()
      {
        Logger = logger,
        ProgressMonitorProvider = NullProgressMonitorProvider.Instance
      };

      launcher.RuntimeSetup = setup;
      Assembly assembly = this.GetType().Assembly;

      FileInfo assemblyInfo = new FileInfo(assembly.Location);

      launcher.TestProject.TestRunnerFactoryName = StandardTestRunnerFactoryNames.Local;
      launcher.AddFilePattern(assembly.Location);
      launcher.Run();
