Room For Improvement

Users want clearer documentation, faster processing, better reports, improved integrations, more device coverage, accurate logging, and responsive support.
Tricentis Tosca struggles with upgrades, high costs, mobile testing difficulties, and requires improvements in AI, UI, and reporting.
Users find Zeenyx AscentialTest's reporting, integration, stability, and documentation inadequate, with a steep learning curve for new users.
The self-healing process should automatically handle any changes in web applications; for instance, if properties change inside the application, the tool should automatically take care of it, unlike other tools such as Mabl and TestComplete that have better self-healing capabilities.
Technical Architect at MOURI Tech
The Vision AI implementation works very slowly, affecting the speed of our work.
Test Automation Specialist at Accenture
Moving to a cloud-based application rather than a desktop one could improve Tosca.

Provides real-time application monitoring, but the technical support services need improvement
They could improve the platform's customer support services. Many users, including myself, have experienced significant delays in response times and unsatisfactory resolutions when reaching out for assistance. The support team often provides generic recommendations that do not address the specific issues raised, leading to prolonged downtime. Additionally, there needs to be more proactive communication and follow-up on reported problems. Another area for improvement is keeping pace with updates to the latest libraries and technologies. For example, Sauce Labs' proprietary driver and Saucectl need to be updated more frequently to support the latest versions of popular testing frameworks like Playwright. This lag in compatibility means that users may miss out on critical features and improvements available in newer versions, necessitating workarounds or compromises in their testing workflows.

Automation test development becomes accessible and effective for functional testers
Tricentis Tosca is a codeless tool, making it easy for everyone to understand the transition of how to develop scenarios or test cases. In Tricentis Tosca, analyzing failures is straightforward because every time it fails somewhere, I get the screenshot, which helps me analyze how and why it failed. It has all the modules, including some pre-built ones that can be reused efficiently. Compared to other code tools such as Selenium, where I used to develop one script in one day, with Tricentis Tosca I can easily develop one script in four hours or three hours, saving four to five hours in a day.

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.
