Compare a value returned dynamically using regEx

Note: the regular expression syntax adopted in TestComplete may differ from native regular expression syntax provided by scripting engines

function Test4()
{
    var str = "Test_QA Abcdef XY1";
    var pattern1 = /Test_QA Abcdef XY\d{1,3}/gm // native regular expression will match 0 - 999
    var pattern2 = new RegExp("Test_QA Abcdef XY\\d{1,3}"); Note \\ is used

    Log.Message(pattern1.test(str));
    Log.Message(pattern2.test(str));
    
    aqObject.CompareProperty(str, cmpMatches, "^Test_QA Abcdef XY\\z$", false, lmError); // TC regular expression
}
