Best Mobile App Testing Frameworks for Android and iOS [2024]

Mobile app testing framework helps automate the testing of your native apps. It reduces test execution time and identifies bugs before the app goes live. Once a mobile application is developed, it is moved ahead to the testing phase, where it is decided whether the application is fit to be delivered to the people or needs more work.

In this blog we will learn the best mobile app testing frameworks for 2024,the list of frameworks mentioned in this blog will help mobile app developers take better decision to build mobile apps in more effect way.

Different mobile app testing frameworks offer different features and may confuse the app tester in choosing the best one according to the situation. To resolve this, we have crafted this post that brings out all the mobile app testing frameworks, popular features, and other relevant information.

Types of Mobile App Testing Frameworks

Mobile app testing frameworks come in three strict divisions:

• Strictly Android testing framework.
• Strictly iOS testing Automation framework.
• Cross platform testing framework (for both Android and iOS).

We have divided this post into three sections and arranged all the mobile app testing frameworks accordingly.

Android Test Automation Frameworks

The following section highlights the most popular mobile app testing frameworks available only for Android applications.

In this blog, we will discuss some of the best Android test automation frameworks, such as Espresso, Selendroid, Robotium, and MonkeyRunner.
