Espresso is a test framework used to write Android UI tests, and part of the Android SDK. The Espresso API encourages test authors to think in terms of what a user might do while interacting with the application - locating UI elements and interacting with them. At the same time, the framework prevents direct access to activities and views of the application because holding on to these objects and operating on them off the UI thread is a major source of test flakiness.

React Native is a framework for building native applications using React. It is open source and free, and developed by Meta Platforms. It enables users to create native apps for Android and iOS using React. React Native combines native development with React, a JavaScript library for building user interfaces.
It is suitable for making portable applications, with almost the same code for several platforms. You can access native features of the device or use an open source plug-in from the repository to create a local database and access the internal storage of the device. It is wonderful for the construction of a native application, through the use of standard web code. It is not recommended for enterprise applications.
We are implementing React Native framework for the development of the Front-End for the machine learning models maintenance and monitoring website. It provides meaningful error messages, and time-saving and robust tools make it a premium choice over other platforms. Moreover, it provides intelligent debugging tools and error report mechanisms. And most importantly for us, it provides the aesthetic minimal functionality to learn in order to implement it, thereby eliminating the need to work in Xcode or Android Studio for iOS or Android apps respectively.
Adobe Phone Gap has an extremely simple user interface that allows for easy learning to occur.
Adobe Phone Gap provides support for web languages and allows you to write in three of the main languages and transfer them to another language for use. This solves a common programming issue and is the greatest strength of the software.
Their desktop application allows for easy installation and programming.
Adobe provides quick support with questions about how to use the software.
The build interface notifies you of errors extremely quickly and helps identify the issue in your programming. You get an easy idea of what needs to be updated and adjusted.
Cordova app code runs inside a webview component. So, expect the performance to be a little slower as compared to the native apps. This is more noticeable on older devices though. It is hardly noticeable when it comes to newer mobile devices.
Crashes can be hard to debug since the crash logs will not point you to the culprit javascript code. This is not a limitation of Cordova alone. Any other hybrid mobile app development platform suffers the same problem.
Even with tools like Safari debugger and Chrome debugger, it can be tricky to measure graphics and animation performance. Achieving smooth animations can be a bit of a challenge sometimes with hybrid mobile apps in general.
As Espresso works on the ideal thread if the threads are not handled properly by the developing team it can lead to challenges in the execution of your tests.
Depends more on the developer's code
we cannot develop tests as individual frameworks, we share the repository with developers.
We need to be cautious while making changes in the tests, as we share same repository
Apache Cordova is the mother of all other frameworks. The Ionic developed framework is well suited for development but most of their features are offered by paid services. As Apache Cordova is open source and has a license to modify it, it has no legal problems to work with it. Also, most well-known IDEs recognize the Apache Cordova snippets.
As our app is complete on Android Espresso is the best choice over Appium Fewer efforts in Espresso over Appium, as Espresso provides some built-in library to perform the operation. Easy to use, Espresso is very easy to understand and we can perform operations with very little code. Developers can contribute, as they have good command over Java and Kotin languages and also use Espresso for unit testing.
Decision for React Native came mainly from the big popularity of the framework. Thus, we had a big base of resources we could come back to. We also used it because it is a javascript framework. Thus, we could utilize the already existing experience in javascript and web development to ensure a smoother implementation of the app.
Decreased the development process time via robust and easy-to-use platform
Easier to debug with a provided intelligent tool as well as error-prone messages, which allows developing in a paced manner for the decreased Time-To-Market
Reusable code base can directly impact lead time and thereby on ROI in a positive manner
