When is Espresso Better than Appium?

Espresso can be considered for testing, if your mobile application is focused on the Android platform. It has greater speed, accuracy, and reliable results. It has very good integration with Android-based tools which makes Android application testing easier and smoother. However, if your mobile application is targeted at iOS and Android, you may need to look for another framework to achieve the iOS testing. This increases the maintenance and testing effort to a great extent.

When is Appium better than Espresso?

Appium is better if your application is targeted to cross-platform such as Android, iOS, etc. Though Appium follows a complex set-up process, once setup is completed it can do a lot more than just UI testing. As Appium is highly customizable and extensible you can configure the framework, as per your requirement.

It is an accepted fact that Appium is highly customizable, but it requires very good technical knowledge to build a framework. Building a good, readable, and robust framework with all integrations can take months. It is a challenging task for any tester or developer. 

To overcome such complexity the best alternative is Testsigma.

Beyond Appium vs Espresso: Are there any other options?

Appium and Espresso, both require good technical knowledge to set up and configure. Both of these are code-based tools, which means that you need to be proficient in one of the supported languages to perform automation scripting. The requirement of coding may upset many users who are less exposed to programming. 

As mentioned earlier, mobile testing is challenging because of its more advanced and demanding infrastructure. Setting up and managing those infrastructures is also challenging. 

Testsigma is one of the best alternative options to address all these challenges with simplicity. Testsigma is an AI-based test automation tool that supports codeless testing of Mobile and Web applications, from the same place.

Dos and Don’ts in Mobile App Testing

Best practices can save a lot more man-hours during maintenance, below are some of the best practices that can help to succeed in mobile automation.

• Never adapt any testing tools without evaluating and knowing the depth of tools. Unknown limitations can block a lot of your requirements in the future.
• Always have a strategy and plan to automate the applications
• Use real devices as much as possible
• Never forget to test the native device features such as Camera, Bluetooth, NFC, GPS, etc. on targeted devices
• Use emulators only during the initial phase, always use real devices to provide sign-offs
• API Testing is as important as UI testing, never forget to test the API’s
• Always give importance to extensibility as much as you can while building the automation framework.
• Infrastructure maintenance is a complex task, testers can be distracted a lot when infrastructure problems arise and productivity can go down. Try to use cloud testing providers rather than private infrastructure.
• If your team members’ skills are limited, explore no code-based mobile test automation tools like Testsigma
