Develop High-Quality Test Data
Test data assumes paramount significance in the realm of data-driven testing. Typically, the data required for automated tests, such as input for application fields, is sourced from external files. These files may draw data from databases or other sources, including text or XML files, Excel spreadsheets, and database tables.
Leveraging external data endows automated tests with reusability and simplifies maintenance. To introduce diverse testing scenarios, you can readily extend the data files with new entries, obviating the need to amend the automated test itself.
While the creation of test data may appear tedious, it is an investment well worth making. Structuring data meticulously enhances the efficiency of automated test creation. By initiating this endeavor early in the testing process, you pave the way for seamless extensions of existing automated tests as the application evolves.
Design Resilient Automated Tests Amidst UI Changes
Automated tests, whether scripted or built using keyword tests, inherently rely on the application under the test’s user interface (UI). As software evolves, especially during its early stages, UI alterations are not uncommon. These changes have the potential to impact the test outcomes, rendering automated tests incompatible with subsequent versions of the application.
The challenge arises because automated testing tools utilize a set of properties to identify and locate objects within the application. On occasion, these tools may rely on positional coordinates to identify objects. For instance, if the control caption or position undergoes modification, the automated test may fail to locate the object during execution, resulting in a test failure. To adapt to such scenarios, you might need to undertake an extensive project-wide search-and-replace effort to update outdated control names before running the test on the new application version.
However, a proactive approach to creating automated tests can mitigate these challenges. By assigning unique names to controls, you fortify your automated tests against UI alterations. This strategy ensures that your automated tests remain functional without necessitating modifications to the test script itself. Moreover, it diminishes the automated testing tool’s reliance on positional coordinates for object identification, thereby enhancing test stability and resistance to UI changes.
