IBM DevOps Test Performance vs. IBM DevOps Test UI

Go for IBM RPT if: 1. You're testing a Java-based Web application with HTTP protocol 2. You wanted to distribute the load across machines easily 3. Your team is in learning phase/not really introduced to a wide range of performance testing tools Do not go for IBM RPT if: 1. You wanted to test REST or any other advanced protocols 2. Your system under test demands a very high user load 3. Your application is written in .NET or any other platform except Java.

IBM Rational Functional Tester is good for automating thick applications.

• Data Parameterisation/ Data Correlation is made simpler compared to its competitors
• Distributed Load Testing is easier to set up
• Performance metric gathering while a test is in progress
• Th look and Feel really helps a beginner to understand and work with.

Incentivized

• An execution log in html format provides detailed information of the actions, verifications, and screenshots with timestamps.
• Quick response and good support. IBM releases frequent updates to handle customer needs and fix issues.
• A solid object inspector, extensive functional library and playback monitor.

Incentivized

• Memory utilization could have been improved.(Eats up system's RAM)! It may crash if a test is conducted with the heavy load if adequate RAM is not available in the VM/host machine.
• Licensing could have been made simpler. IBM's licensing method is difficult to follow.
• Support for protocols other than HTTP. Not really up to the current trend.

Incentivized

• Installation or updates were not always perfect. Would have to clean previous installations or reinstall Java if there were errors.
• No or very limited support of browsers outside of Internet Explorer.
• Uses a lot of memory, can have memory issues on large tests.

Cost/Licensing: While JMeter is an opensource testing tool from Apache, compared to IBM RPT and HP LoadRunner, RPT is much cheaper than Loadrunner. Functionality: JMeter provides basic functionalities which are adequate for performance testing, however advanced features are not available (such as load testing with GUI, reporting is very basic etc.). But when it comes to Loadrunner, it offers very broad features and supports a variety of protocols. So in this category, Loadrunner is a winner, but RPT is better than JMeter. Ease of operating: JMeter is easy compared to LoadRunner, but it has old GUI and look and feel is not that great to understand. Also, most of the things are to be done in a command line, non-GUI mode. While LoadRunner is very advanced with many options, which also confusing sometimes. But RPT, on the other hand, maintains a balance between simplicity and offering of different features. So winner: RPT.

Selenium is similar to IBM Rational Functional Tester but is not as user friendly and does not support thick applications. Visual Studio Coded UI is newer so not as refined; the object inspector/management and execution log results is poor compared to IBM Rational Functional Tester.

Incentivized

• Accuracy in metrics, thus improving system's performance
• Costs less compared to competitor like HP LoadRunner
• Helped the team of beginners learn things quickly

Incentivized

• Speeds up and broadens the testing cycle by using machine time for regression testing.
• Frees up time for testers to focus on critical items outside the automated suite.
