Description

Test generation for Functional interfaces defined as class members - fails with InaccessibleObjectException from constructCompositeModel

To Reproduce

Steps to reproduce the behavior:

  1. Open IntelliJ IDEA
  2. Plugin is installed
  3. Create a new project with JDK 8
  4. Add a class LambdaVarExample (see below)
  5. Run test generation
  6. Repeat 3-5 steps for a project with JDK 11
import java.util.function.Predicate;

public class LambdaVarExample {

    private Predicate<? super String> byCondition = l -> l.contains("b");

    public void runTest(String input) {
        if (byCondition.test(input)) {
            firstScenario();
        } else {
            secondScenario();
        }
    }

    private void firstScenario() {
        System.out.println("1");
    }

    private void secondScenario() {
        System.out.println("2");
    }

}

Expected behavior

5-6. Tests are supposed to be generated without errors.

Actual behavior

An error test is generated with information about...
5. JDK 8 - ClassNotFoundException in concrete...
6. JDK 11 - InaccessibleObjectException in constructCompositeModel.

    • JDK 8 - cannot reproduce ClassNotFoundException, but got Default concrete execution failed error, which comes from fuzzer - @Markoutte take a look, please. Also, found wrong assertions from symbolic assertions (see the attached screenshot) - going to investigate.

    • JDK 11 - found the mentioned exception in runIde logs, and no expected non-exceptional executions - going to investigate. Also, Default concrete execution failed error again - @Markoutte take a look too, please.

    @Damtev looks like the problem that we cannot find lambda class to construct concrete "this" object. In this case the field cannot be created because Predicate uses a lambda. If we use anonymous class it works ok for fuzzer:

        private Predicate<? super String> byCondition = new Predicate<String>() {
        @Override
        public boolean test(String s) {
            return s.contains("b");
        }
    };

    You can find the field gathering in UtModelConstructor#constructCompositeModel:295:

    .forEach { it.withAccessibility { fields[it.fieldId] = construct(it.get(value), it.type.id) } }
