Enzyme vs Visual Studio

Postman will be used to do integration testing with the backend API we create. It offers a clean interface to create many requests, and you can even organize these requests into collections. It helps to test the backend API first to make sure it's working before using it in the front-end. Jest can also be used for testing and is already embedded into React. Not only does it offer unit testing support in javascript, it can also do snapshot testing for the front-end to make sure components are rendering correctly. Enzyme is complementary to Jest and offers more functions such as shallow rendering. UnitTest will be used for Python testing as it is simple, has a lot of functionality and already built in with python. Sentry will be used for keeping track of errors as it is also easily integratable with Heroku because they offer it as an add-on. LogDNA will be used for tracking logs which are not errors and is also a Heroku add-on. Its good to have a separate service to record logs, monitor, track and even fix errors in real-time so our application can run more smoothly.

The problem I have is whether to choose Android Studio or Visual Studio? I have to develop a simple app for a school project that can work on both iPhone and Android.

The most important factors for me are Android and iOS compatibility. Although note that i would like to become a Software Engineer when i finish my course. (I'd like to work for Apple, just saying!)

After that id like easy integration for Google Ads and such if i do develop another app that people actually use to support development. (I'd also like to stick with one easy programming language that's compatible with a wide variety of platforms since i'm a beginner and have only ever used Pascal)
