We can edit captured transactions and organize them by those for which we require performance metrics, but it lacks a set of manuals or guides that would take out some guess work.

It is used to capture and generate HTTP tests. The capture process is very easy. After this, we edited the captured transactions to organize them into the sections or transactions we require performance metrics for (i.e. splash page, user authentication, main pageload, logout, etc.). This editing process is easy to perform with the interface provided in Rational Performance Tester Finally, Rational Performance Tester has an import/export feature that has been extremely useful. We have used it to export our complete test library and import it into another Rational Performance Tester server with no loss or issues. This allows for platform test migrations and backup.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It can support both web applications and mobile applications, and in certain cases, it can also support testing of desktop applications or software-based applications. You can write web applications, mobile applications, and software-based applications."

"Technical support is very good. I'm very satisfied with the assistance we've received so far."

"It’s been really easy to automate the same application TestComplete struggled with. I have been able to automate two of our key applications in just a few months. I haven’t even taken their training."

"The most valuable feature of AscentialTest for us is that it fully supports PowerBuilder."

"AscentialTest's object recognition in snapshots is a robust feature that goes beyond standard elements, even accurately identifying objects within Datawindows."

"If you use the PowerBuilder application, do choose AscentialTest without thinking twice."

Cons

"The solution is not easily scalable. If you want to extend the solution, you need to purchase a different kind of license. You also have to work with the IBM team to assist in scaling."

"There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies."

"Streamlining the retrieval of results from individual test set runs would be beneficial."

"I would like to see an improvement in the User Interface."

"Classes are not as object-oriented as I would like, but I am a programmer and not QA so I expect a lot."

"The only thing I can't wait for is for Zeenyx to add automating Mobile apps."

Pricing and Cost Advice

"It is much cheaper than Micro Focus LoadRunner. We need perpetual licenses. Support is included in the first sale. After that, you need to renew support every year."

"Once it starts generating ROI, which for us took between three and six months, one will not even think about the investment."
