What does Android Automation Testing mean?

But first things first, what really is Android automation testing? This term refers to the act of using certain tools and frameworks to automate the process of testing an application that has been designed for Android devices. In other words, with the help of automation testing, different functionalities can be ensured over varied user interactions like touch or non-touch input across many devices without missing out on anything.

Historically, manual testing was needed to test Android applications, which meant that testers had to follow through with every scenario provided by test cases one at a time. Nevertheless, this approach was not only laborious but also prone to mistakes as well as ineffective, especially when there were numerous device  operating system versions required for testing. 

This issue is addressed through Android automation testing, which involves running similar test cases automatically either on emulators or real machines and giving out dependable outcomes at all times.

Why is it Vital to Automate Tests on Android Applications?

• Speed and Efficiency: The fast execution speed of automated tests enables a more thorough test carried out within a shorter period.
• Reusability: After creating automated tests once, they can easily use them again in future versions without wasting much time or energy.
• Consistency: With automation, running tests follows a consistent pattern, hence reducing chances for human errors.
• Continuous Integration: Continuous Integration depends upon automated testing through which teams can verify their code on every new change or update done automatically.
• Cost-Effectiveness: Although setting up an automation framework may take up some time initially, it helps in cutting down on manual testing expenses over the long run, hence proving itself as a cost-effective option.

Having understood the relevance of Android automation testing, we shall consider some tools, frameworks and strategies that would facilitate effective automation.
