When you record a functional test script to test an application, simplified scripts are generated and displayed in the Script editor. The corresponding Java test script is displayed in the Java editor.
While working with the simplified scripts, you can switch to Java scripting to use some of the Java functions such as APIs by using the Insert Java snippet and Insert Java module features available in the simplified script editor. Advanced users can work with Java scripting instead of working with the simplified test scripts.
The simplified scripting feature is enabled by default in the IBM IBM Rational Functional Tester preferences page. To work with Java scripting, you can disable the simplified scripting feature. The application visuals feature is not available while working with Java scripts, instead use the functional test object maps.
