How to pass the list of EmployeeDetails.class to the JUnit parameterized class.

Please help me on writing the Parameters method

@Parameters
public static Collection employeeList()
{
    List<EmployeeDetails> employees = new ArrayList<EmployeeDetails>;
    return employees;
}

// This throws error like "employeeList must return a Collection of arrays."

EmployeeDetails class above is for an example. I need to use it for a similar class where i will send the list of the class objects.

Your @Parameters method must return a collection of object arrays. So assuming your test case constructor just expects one EmployeeDetails object, do this:

@Parameters
public static Collection<Object[]> employeeList() {
    List<EmployeeDetails> employees = new ArrayList<>();
    // fill this list

    Collection<Object[]> result = new ArrayList<>();
    for (EmployeeDetails e : employees) {
        result.add(new Object[] { e });
    }
    return result;
}
