ceylon test ParameterNameParserException with Class with multiple argument lists #7381

Open aedeph opened 6 years ago

aedeph commented 6 years ago

ceylon test and ceylon run with createTestRunner().run() produces ParameterNameParserException, when there is private method with multiple argument list.

import ceylon.test { ... }

class ClassTest() {

    Integer stub()(Integer i) => i;

    test
    shared void runTest() {}
}

shared void run() {
    ClassTest().runTest();

    print(createTestRunner([
            `ClassTest`
    ]).run());
}

$ ceylon run --compile=force repl

com.redhat.ceylon.model.loader.ParameterNameParserException: Too few parameter types

$ ceylon test repl com.redhat.ceylon.model.loader.ParameterNameParserException: Too few parameter types ...long stack trace..

However, if second argument list is empty (Integer stub()() => 1), everything is ok.

I can reproduce this on current master; the stack trace is:

And here’s a simpler reproducer – ceylon.test not necessary:

class ClassTest() {
    Integer stub()(Integer i) => i;
}

shared void run() => print(`ClassTest`);
