Testing the validator, programmatically [message #633042]

In chapter 5. Runtime Concepts, section Test Validators of the users guide, methods for testing the validator are described. Unfortunately, only method for building a model manually is described, but not how to use the "can ...use EMF's ResourceSet to load models from your hard disk" method.

Does someone have some example (code) for me how to do that?

Thanks!

You can call the validation like this:

XtextResource res = (XtextResource) myResource;
List<Issue> issues = res.getResourceServiceProvider()
.getResourceValidator()
.validate(res,
CheckMode.ALL,
CancelIndicator.NullImpl);

Hello Sven,

I just tried to insert this code schnipsel, but in vain. 1st I got an error message with "CancelIndicator.NullImpl" I can't resolve. Either import from "org.eclipse.xtext.util" nor from "org.eclipse.xtext.validation" works!

BTW. where I have to place this code schnipsel? I added two classes under validation extending AbstractXtextTests and AbstractDeclarativeValidator as suggested by the user guide.

... and what is "myResource", is this just an input stream for the text of my DSL? A think, one have to convert the text file into something for getting a "myResource"?

Thanks ...

Sorry, I think it's "new CancelIndicator.NullImpl()"

In your unit test.
If you extend AbstractXtextTests, then you can obtain a Resource for
your model (string literal) like this:

XtextResource myResource = getResource(new
StringInputStream("my.dsl(expression)"));
