Apache JMeter vs. BMC AMI DevX

JMeter is well suited for Java applications where the user can script the scenario once and make changes to accommodate for as many numbers of users for load test execution. The image and selection of any files or exporting files scenario is handled well.

It is less appropriate to test Ajax applications where it is required to script click per use.

I'm not sure what scenario it would not be suitable for. I have it up all day, though I do use the mainframe emulator to go back to the old 'green screen'. We have tools that we must use there. There is very little I can't do on the workbench. I'm trying to get some of our new developers to use it, as when I'm using it and talking to them on the phone, they don't know what I'm talking about.

• Easy of use - in generate load like HTTP requests, and processing/analyzing the responses. No coding is necessary at the basic level, just need to understand load testing and the infrastructure being tested.
• Automatic management of things like cookies to help with session state support - so you don't specifically have to worry about it or handle it
• Lots of testing/configuration options to suit your needs in making the right load generation (sampling requests), and analyzing the results, including any pre and post processing of the results first. Things like the Beanshell/BSF pre/post processors, response assertion, regular expression extractor, XPath extractor, CSV data set config
• There is a JMeter cloud service called BlazeMeter that I think would be useful for those that need to scale up high load without provisioning their own systems. I've not personally tried it though, but I recently attended a meetup presentation that highlighted nice useful features that BlazeMeter provides. One should evaluate the service if they are considering JMeter and need to expand beyond existing hardware resources.

• Code Pipeline: integration of MF and non-MF type of object (COBOL, Java, zosconnect...). Deployment of objects coming from inside and outside the mainframe in the same way.
• Workbench for Eclipse: a must-have for working with Code Pipeline and the mainframe in the development context.
• Workbench for VS Code: They started developing VSCode, and the plugin works very well. There are a lot of things to add, but it's still very good. Young developers like it!

• Jmeter requires many tweaks with respect to its configuration file and thread properties. users need to edit theses files themselves. There could be some interface where we can edit this fields.
• Jmeter cannot handle more threads and hangs up when we increase the number of threads. This causes lot of inconvenience. In these situations, user can be notified that such change would be lead to slow performance so that user can do as required. The same appears when we try to view huge files on graph listener.
• Jmeter should optimize the read and write access to output csv since it acts as overhead to the I/O performance. This affects our test results for the application which we are testing.

• Better font/visual customization (nice dark mode, more accessible font sizing).
• Better integration with Changeman, not sure if this is BMC AMI DevX specific but some issues do arise with interfacing with CMN.

Price, Wiki and user sharing. Having access to the information provided by the developers and other open source providers is key for me. The ability to share information and get answers directly is very important to success in software testing. And the price of this product currently is amazing. Too many companies charge way too much money for products that are far behind in their value and pertinence

I can jump right into a new test plan and start building from scratch. The natural progression from test plan to thread group and then designing the basic format of the process is very streamlined and smooth. With only slight modifications I can build out a very complex model from a very basic beginning.

I have been using JMeter for the last year. By using this tool, you can make sure the system will work under varied loads. It helps us to simulate real time scenarios by creating required virtual users and make sure the application will work under load. Perform load, stress, and stability testing using JMeter.

Support has been amazing compared to Optim. Further, new features are very regular with File-AID - I can't remember the last time Optim had a significant update. File-AID support is very receptive to feature requests and reported bugs, including sending out hotfixes quickly.

I have used LoadRunner and Silkperformer, and so far Jmeter turns out be the easiest to use of all these. While each of them have their own ROI, Jmeter can be picked by anyone in hours and start testing within a day. While with other tools, we need to get license, install them (takes a while) and setup tests and firewalls, etc.

Optim is more user friendly in how it operates, in my opinion. It's less obtuse to figure out how to extract and mask the data required compared to File-AID. Further, Optim is easier to gather related tables, by far. I do prefer using File-AID via the Topaz GUI much more than using Optim via its GUI. Finally, I personally believe that File-AID is significantly faster to run than Optim - this could be a configuration issue.

• Good ROI on improving the performance of the application.
• Finding issues in the performance.
• Benchmark the performance results.
• CON: Need skillset to create and maintain the scripts in Java.
• Scripts are reusable and it is executed by any user.
• Need Client and Server setup to execute the scripts.

• I can debug (expeditor) much faster and more efficiently. In fact, I was asked yesterday to run their job through Workbench Expeditor. I can also view data movement much better.
• Code analysis lets me give a quicker explanation of what a program may do, as it provides a graphical interface showing processing and data movement.
