I'm upgrading IronPython 2 from B4 to B5 and one of my unit tests is
aborting with InvalidProgramException exception in
Microsoft.Scripting.Actions.MatchCaller.Call6.
The problem occurs if in the Python statements I try to import anything, no
matter what.
No import statement, no error. Also, when executed directly, without a unit
test, the same code runs correctly.
Is this a bug?
Source code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using NUnit.Framework;
using Microsoft.Scripting.Hosting;
using Microsoft.Scripting;
namespace HelloDLRWorld
{
[TestFixture]
public class DlrTest
{
[Test]
public void ImportTest()
{
ScriptRuntimeSetup srs = ScriptRuntimeSetup.ReadConfiguration();
ScriptRuntime runtime = new ScriptRuntime(srs);
runtime.LoadAssembly(typeof(System.Diagnostics.Debug).Assembly);
runtime.LoadAssembly(typeof(System.Double).Assembly);
ScriptEngine pyEng = runtime.GetEngine("IronPython");
ScriptSource source = pyEng.CreateScriptSourceFromString(@"
import System.Diagnostics
output='hello world from DLR/IronPython'
System.Diagnostics.Debug.WriteLine(output)
", SourceCodeKind.Statements);
ScriptScope scope = pyEng.CreateScope();
source.Execute(scope);
object outputMsg = scope.GetVariable("output");
Assert.AreEqual("hello world from DLR/IronPython",
outputMsg.ToString());
}
}
}
Test result:
------ Test started: Assembly: HelloDLRWorld.exe ------
TestCase 'HelloDLRWorld.DlrTest.ImportTest'
failed: System.InvalidProgramException : Common Language Runtime detectou um
programa inválido.
