Hello everyone,

I was following Christian Dietrich's guide to test my code generation.

I have created a new xtend file specifically for testing the code generation.
Here is its content:

package com.bbraun.interfaceparser.tests

import  org.xtext.example.mydsl.Model
import org.xtext.example.mydsl.MyDslInjectorProvider
import com.google.inject.Inject
import org.eclipse.xtext.generator.InMemoryFileSystemAccess
import org.eclipse.xtext.testing.InjectWith
import org.eclipse.xtext.testing.XtextRunner
import org.eclipse.xtext.testing.util.ParseHelper
import org.junit.Assert
import org.junit.Test
import org.junit.runner.RunWith
import org.eclipse.xtext.generator.IGenerator

@RunWith(XtextRunner)
@InjectWith(MyDslInjectorProvider)
class CodeGenerationTest 
{
	@Inject ParseHelper<MemberFunctions> parseHelper
	@Inject IGenerator underTest
	
	@Test
	def void kickoffTest()
	{
		val result = parseHelper.parse('''
			Hello There!
		''')
		val fsa = new InMemoryFileSystemAccess()
		underTest.doGenerate(result.eResource, fsa)
		val errors = result.eResource.errors
		Assert.assertTrue('''Unexpected errors: «errors.join(", ")»''', errors.isEmpty)
	}	
}

When running I got the following error:

com.google.inject.ConfigurationException: Guice configuration errors:

1) No implementation for org.eclipse.xtext.generator.IGenerator was bound.
  while locating org.eclipse.xtext.generator.IGenerator
    for field at com.bbraun.interfaceparser.tests.MemberFunctionsParsingTest.underTest(Unknown Source)

	at org.eclipse.xtext.testing.XtextRunner.createTest(XtextRunner.java:33)
...

I have found this bug, but it is fixed as mentioned here

Can someone help me solving me this somehow?

I am using Eclipse 2019-09 and Xtext 2.19.0.

Thank you in forward!
