We should avoid hard coding of paths in tests as this adds to portability of test from one machine other. Consider an action having following statement – Execute File (D:\GSB\QTP\fucntion\test.vbs) When tests are ported on a different machine then there is no guaranteed about drive mapping being same. To over come this, we can read path run time instead of hard coding it; as following - Make sure assignment of Global is first action as only then Run Time Env file would be available for usage.
