Compiler tests for multi-DSLs? [message #1780733] Fri, 26 January 2018 11:53 Go to next message

I found some nice resources how to use 2 DSLs: e.g.


That also helped me to get all parsing tests working.

Example:
in project xtext-multi-dsl we have MyDslA which does not know anything about MyDslB.
MyDslB on the other hand imports MyDslA (and thus depends on MyDslA).

In this case I can write a simple compiler tests-working for the MyDslA.
But how can we write compiler tests for the MyDslB (which is dependent on MyDslA)?

e.g. I think I'd need to:

  • first load the sub-dsl model file
  • trigger the sub-dsl generator
  • put the generated files on the classpath
  • load the super-dsl model file
  • and finally generate and check the generated super-dsl files


Maybe there is already some example project for such tests?

what do you means by sub and superdsl and how do the relate to each other
if these are simple dsls referencing each other simply load both files at once is the way to go.
the only thing you may need to make sure is that the standalonesetups for both dsls are called.

Sorry, these terms were wrong. I had them from another example. I've edited the question to clarify.

And how could I do that?
e.g. currently I just pass the model as string to CompilationTestHelper.compile()

same as your other questions. have a look at the compilation test helper code and improvise ....

@RunWith(XtextRunner)
@InjectWith(DomainmodelInjectorProvider2)
class CompilerTest {
	
	static class DomainmodelInjectorProvider2 extends DomainmodelInjectorProvider {
		
		override protected internalCreateInjector() {
			XtendStandaloneSetup.doSetup
			super.internalCreateInjector()
		}
		
	}
	
	@Rule
	@Inject public TemporaryFolder temporaryFolder 
	@Inject extension CompilationTestHelper
	@Inject extension ReflectExtensions

	@Test
	def void testGeneratedJavaFromSeveralInputs() {
		resourceSet(#[
		"a.dmodel" -> '''
			entity Foo {
				bar : Bar
				op doStuff(String x) : String {
					return x + ' ' + bar.getName()
				}
			}
		''',
		"b.dmodel" ->'''
			entity Bar extends Bat {
				name : String
			}
		''',
		"Bat.xtend" -> '''
		class Bat {}'''
		]).compile [
			Assert.assertEquals(''''''.toString, singleGeneratedCode)
		]
	}
	
	
	
	
}

Thanks that works! I didn't think it could be that easy :)

Here's a simplistic test-project (using gradle): ex.xtext.twog Tag:CompilerTestOk
