Misordered 'assertEquals()' arguments

Reports calls to assertEquals() that have the expected argument and the actual argument in the wrong order.

For JUnit 3, 4, and 5 the correct order is (expected, actual). For TestNG the correct order is (actual, expected).

Such calls will behave fine for assertions that pass, but may give confusing error reports on failure. Use the quick-fix to flip the order of the arguments.

Example (JUnit):

assertEquals(actual, expected)

After the quick-fix is applied:

assertEquals(expected, actual)
