Using ValidationTestHelper to detect "missing EOF at 'MyElement'" error [message #1711235]

Hi,

I followed a tutorial on using the validation helper. However, it only showed me how to uses it for custom error classes with the MyDslValidator class.

How do I write an .parse.assertError(... Statement for such generic (system) errors?

Thank you!

You can just start with assertNoErrors and then you will see the actual errors in the Junit view. Then you know what to assert.

org.eclipse.xtext.diagnostics.Diagnostic has the error codes for syntax/linking validation
org.eclipse.xtext.xbase.validation.IssueCodes has the error codes for Xbase validations

Ok,

debugging further resolved the mytery: mycode.parse.assertError(MyPackage.eINSTANCE.myrule, org.eclipse.xtext.diagnostics.Diagnostic.SYNTAX_DIAGNOSTIC, "missing EOF at 'FOO'")
