Lead Consultant at a tech services company with 10,001+ employees
Provides multiple test environments and saves time, but should have something for inspecting mobile apps screens
With the desktop browser, we can inspect any screen with the web developer option, but they should provide something for mobiles so that we can quickly inspect elements on the device. To write the Selenium scripts, we require web locators. We have to capture them from the local and execute the script on Sauce Labs. If Sauce Labs can provide a solution where we can inspect any of the mobile devices online, it will be very helpful for us. I also faced an issue where during the execution time, the iCloud password used to expire within a certain period, which used to create pop-ups on the screen making our tests fail. That was one thing that we faced many times. If that can be improved, it will be very helpful.

Test Automation Architect at a tech vendor with 10,001+ employees
Integrated collaboration with automated test management has improved our agile workflows and continuously supports quality reporting
Visual Studio Test Professional could be improved as earlier we had flexibility in automation testing with TFS, which became a bit difficult moving to Azure DevOps. Additionally, in Visual Studio Code, we have an agent mode for GitHub Copilot, which is very helpful in testing or development phases, while Visual Studio's GitHub Copilot is a bit tricky and sometimes does not provide my desired output.For future improvements, I would like to see prompt fixing, as currently, if something goes wrong in Visual Studio, the fixing options are not always correct. If that intelligence is embedded, it would be very helpful.

Robust automation with reusable steps and seamless integration
The concept of reusable steps in Zeenyx AscentialTest has significantly enhanced our test automation efficiency. Encapsulating common actions into modular steps reduces redundancy in test scripts and ensures consistency across scenarios. This approach streamlines maintenance efforts, allowing updates to be applied universally, making our test suite more agile and adaptable to evolving project requirements. The concept of reusable steps is a key factor in maximizing reusability and maintainability in our test automation strategy. AscentialTest's object recognition in snapshots is a robust feature that goes beyond standard elements, even accurately identifying objects within Datawindows. This capability ensures precise interaction with various components of an application's interface, further enhancing the reliability and effectiveness of our automated tests.
