The BlazeMeter Continuous Testing Platform is a unified, end-to-end, next-generation software test automation platform built for both Agile and COE teams, from Perforce. BlazeMeter includes complete continuous testing capabilities deeply integrated into a single, intuitive workflow.
1. It's open source which supports range of languages, operating systems and languages. Well suited for Android and IOS mobile automation. Supports all kinds of apps, which makes it flexible and robust mobile testing tool 2. It is less appropriate where we need intercept network call to verify the API calls. Extensive coding experience is required to work Appium
It is well suited for applications that are mission-critical or applications that can receive high traffic/transactions at unscheduled time periods. Using the load testing feature of BlazeMeter, we can test and ascertain the capacity of the application without the drawbacks of the usual Apache JMeter load testing which depends heavily on the host system from where the load testing is performed.
I would like to give 9/10 rating to Appium because of it can easily integrate with popular frameworks and CI/CD tools, as well as it is reliable, flexible and easy to use. The setup can bit complex in initial step, but once on configured it's very easy to use and enables stable and scalable mobile automation for real and cloud devices.
If you're an Apple developer, you use Xcode. It's practically a forced necessity. For system testing though, it doesn't have to be. You can have your development team focus on unit and integration tests in their platform and another team automate acceptance tests with a language they are more familiar with.
Personally, I prefer using JMeter + Redline13, however we had some business folks that wanted to be able to run a few of their own tests. The non-technical individuals preferred to use Blazemeter because of its simple and intuitive UI.
