TestFlight is a test tool that aims to make it easy to invite users to test apps and app clip experiences and collect valuable feedback before releasing your apps on the App Store. Users can invite up to 10,000 testers using their email address or by sharing a public link.
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
The most appropriate scenario in which TestFlight can be used is when we are in a very large project and we need several people to be able to test the build that we have created. The least appropriate scenario would be when a user is starting to learn to develop applications in iOS since simply by using the tools that Xcode gives, what is the programming IDE. You can test the applications on your device or in the simulator, but this is a really good tool to learn in that scenario but is not mandatory.
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.
When it comes to simplicity and effectiveness, TestFlight makes it much more appealing to run multiple test cycles and get much hight reporting than in cases of the competition. In some cases, the knowledge ramp-up speed is worth focusing on TestFlight as it's super fast and intuitive, and easy. Almost like it's not required at all.
