Description

JUnit4 does not allow to run tests for both outer and inner class.
To avoid losing coverage, we locate all test methods for inner class in a body of outer test class.

Type of Change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Regression and integration tests

Standard scenarios to generate and run tests with nested classes for ALL supported test frameworks
Regression checks for classes without nested ones.

Manual Scenario

Check test generation for the following class

public class OuterClass {

    public int sum(int a, int b) {
        return a + b;
    }

    public class InnerClass {
        public int min(int a, int b) {
            if (a > b) return b;
            else return a;
        }
    }
