Good reporting and interface, but supports limited types of protocols and requires low-level script editing

It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script.

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.

Quotes from Members

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

Pros

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."

"IBM Rational integrates the testing software as Rational Test Workbench, which is quite convenient and efficient as it is able to automate the test scripts."

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."

"All IBM testing tools are really well integrated."

"Using service virtualization, we are able to accelerate the testing and development activity."

"The solution has plenty of features compared to other solutions."

"Improves the software quality in production by finding more defects with automated test sets, before transporting developments to production."

"Testsuite accomplishes what a lot of different tools did before."

"Tricentis Tosca can be easily integrated with SAP infrastructure."

"I am impressed with the product's script test."

"We've found TBox to be valuable for scanning applications and automating test cases."

"Tricentis Tosca is different and better, because it has a reusable model, whereas the others do not."

"Test case automation and ease of test case maintenance through Tosca has reduced the manpower needed for testing, reducing the time needed for testing, and has thus saved money."

Cons

"It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there."

"There are a number of things that they can do to simplify the tools, but the most important thing that they need to do is simplify the installation."

"It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script."

"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."

"Implementing custom functions is bit tedious job, as ECMA script does not support some of the standard java-script functions, Also the Script editor window is not user friendly."

"ScratchBook execution needs to be improved as Tosca crashes multiple times."

"If you need to improve one of the Tosca engines, you have to develop it in the same language, such as C# and Java, so you need more technical experts to help you."

"They should have a different license policy for medium and small companies."

"Scaling can be tedious."

"With regard to areas of improvement, report customization should be easier. It would be good if Tosca could provide standard reports for at least 20 variants. At present, there are only three to four variants. The mobile engine needs to be faster and easier to use; it is a bit cumbersome. Also, the object identification in the mobile engine needs improvement. I would like to see easy-to-use customizations for reports in the next release."

"The disadvantage is that it is very expensive."

"At the time I was using the product, the reporting function was lacking in usability and detail."

"The solution needs to improve its simulation of mobile environments. Right now, that aspect is really lacking."

Pricing and Cost Advice

"The pricing is a little bit on the higher side, although it is really good."

"It doesn't really concern me. Licensing is on a yearly basis."

"Tricentis Tosca may be relatively on the higher side in terms of pricing, but their sales rep can give pretty decent deals when asked."

"It is an expensive tool compared to other test automation tools. It has a lot of advantages over other tools."

"There are two licenses: single user and multiple user. A multiple-user license means that several people can work together on one project and collaborate on code stored in a central location. A single-user license is for people working alone on a one particular application. It's much cheaper than a multi-user workspace. If you are getting a large volume of licenses for an enterprise, you can probably negotiate a discount, but I'm not sure about that."

"The pricing of the solution comes as part of our Tosca bundle."

"On a scale of one to ten, where one is very cheap and ten is very expensive, I rate the pricing a ten. The licensing model is based on a yearly basis."

"I am satisfied with the cost."

"Tricentis Tosca should improve its pricing. It is expensive."

"The price of Tricentis Tosca is approximately Є10,000 for one license. However, it used to be much cheaper, but they changed their license structure. It used to be a structure where if you bought a license you would receive one year of free support and maintenance. Now they only have a yearly license, and that is expensive."
