Supports web and mobile applications, very scalable, very stable, and wonderful support

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.

"Zephyr really improves the testing of the product on many levels - planning, test case creation, automation goals, test reporting, and verification of the testing."

"It has many features, but the main things that we need are the test cycles and integration with automation because we have automation for the web and mobile applications. We use it for test case management to run the test cases and get the results. At this moment, it is fulfilling our requirements.

"It has a very intuitive user experience."

"It has 90% of the basic features you need without having to pay a lot of extra money."

More Zephyr Enterprise pros

Cons

"Installation and configuration processes, and support from IBM all need to be improved."

"I’d like to see a tighter integration with Rational Quality Manager and the Jazz platform."

"Support for more protocols is required."

"We had open many PMRs for problems found in the products, and I'm not sure if all of them have been fixed."

"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."

"User friendliness can be better, as this is one area where it lacks."

"It was complex."

"The installation and tool setup can take some time, since this involves several components."

More IBM Rational Performance Tester cons

"Security needs improvement to protect customer information better."

"Zephyr Enterprise needs to redesign the reporting."

"The solution is not really stable. Sometimes in the past, some pages wouldn't load due to issues."

"We have a lot of automation for our products, and we require a utility for its integration with automation. Currently, we have to write this utility ourselves. It would be great if they can provide such a utility."

"It's difficult to export the test cases in Zephyr, especially with screenshots or attachments, making sharing test cases not very easy."

"The reporting, and the ability to reorganize the test repository, which are a little stifling. There is definitely room for improvement there."

"We faced some errors while uploading the test cases."

"We would like support for the agile and behavior-driven development (BDD) approaches."

More Zephyr Enterprise cons

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."

"It costs a couple of thousand dollars for a little more than 125 users, per month."

"DFS is more expensive than Zephyr. DFS is around $32 per person, whereas Zephyr is $10 per person. There is a major difference in the price, which is the main reason why we are trying to shift to Zephyr."
