Test script transformation analyzer with change guide engine
A script analyzer with change guide generates accurate test scripts for evolving applications. Applications often have complex graphical user interfaces for which the permutations and combinations of GUI elements give rise to an enormous field of potential commands and command sequences to be tested. Furthermore, these applications change over time, rendering prior test scripts unworkable. The script analyzer automatically generates new test scripts to reliably test subsequent application versions, while greatly reducing the time, cost, and resource expenditures needed to arrive at subsequent application versions.
1. A product for test script transformation analysis for generating a transformed test script for a subsequent graphical user interface application (GAP) version arising from a current GAP version to test the subsequent GAP, the product comprising:
a non-transitory computer readable medium;
difference model logic stored on the machine-readable medium operable to produce a graphical user interface (GUI) difference model capturing a GUI element change from the current GAP to the subsequent GAP for a specific GUI element; and
script analysis logic stored on the machine-readable medium operable to:
receive the GUI difference model;
receive a current test script representation for a current test script for testing the current GAP, including a test script statement vector;
locate, in an object repository, a GUI object entry matching the test script statement vector;
locate, in the GUI difference model, a GUI element difference entry matching the GUI object entry;
analyze the GUI element difference entry to determine whether the specific GUI element has changed; and
output a change specifier for the current test script, when the GUI element analysis determines that the GUI element has changed, where the change specifier identifies: either of a wrong path-delete type change guide message, or a wrong path-same type change guide message, or a changed-element type change guide message, or any combination thereof.
