Item {
    resources: TestCase {
        name: "URL"

        function test_url_compare() {
            // passes even though should fail!
            compare(Qt.resolvedUrl("a"), Qt.resolvedUrl("b"))
        }
        function test_url_verify() {
            // fails as it should
            verify(Qt.resolvedUrl("a") == Qt.resolvedUrl("b"))
        }
   }
}
