Android Testing - Getting Started with Espresso 2.0

In this video we cover how to set up your Android Studio environment to use Espresso 2.0. We talk about matchers, assertions and how to use them. We also demonstrate a simple TDD (Test Driven Development Method) implementation for the first test. At the end of this screencast you should be able to set up your Android Application with the Espresso Testing framework.

Testing on Android Explained (Unit, Instrumentation, UI)

Register to take the course:


In this video I explain the three different types of tests:
1) Unit Tests (local)
2) Instrumentation Tests
3) UI Tests

I explain the differences between these tests and the different directories responsible for hosting the test classes.

I also talk about some of the common third party libraries you'll use when writing these tests. Libraries like:
1) JUnit
2) Mockito
3) Expresso

Page Object Pattern and UITest Best Practices | Xamarin Developer Summit

It is a pattern we like to use in our team when writing UITests that are functional, easy to maintain and also cross platform! The best part is the pattern is testing framework agnostic. We started with using it with Xamarin.UITest (for C# Tests) and were able to apply it to other UITesting platforms like XCUITest, Espresso, etc. The session demonstrates the page object pattern (POP) through a live code session. We have tried both simpler and more complex architectures in the past and have found this approach to be one of the best. It is easily adopted by people who are learning how to write tests, but also provides the scalability needed to build out larger, more complicated test suites.

This session was recorded live at the Xamarin Developer Summit: July 11th-12th 2019 in Houston, TX. The Xamarin Developer Summit is a premiere community-run, cross-platform, mobile developer conference, to learn more head to

Unlocking New Testing Capabilities with Espresso Driver by Daniel Graham #AppiumConf2019

Android's Espresso framework was created as a gray-box testing framework, gray-box meaning that it's an automated UI testing framework (black-box) but it has access to the internals of the application (white-box). Allowing access to the internals of the application-under-test opens up many new testing possibilities that weren't possible with UiAutomator2 (with some risks).

Here are the four new possibilities I would like to discuss (with coding examples):
- Access to internal app code
- Less flakiness thanks to IdlingResource. No need for 'waits' and 'delays' for UI.
- Navigate WebViews using Espresso WebAtoms
- Find elements off-screen using Espresso's DataMatchers

GTAC 2013: Espresso: Fresh Start to Android UI Testing


Slides:

Valera Zakharov , Google

Developing a reliable Android test should be as quick and easy as pulling a shot of espresso. Unfortunately, with existing tools, it may feel more like making a double-shot-caramel-sauce-upside-down-single-whip-half-decaf-latte - confusing and rarely consistent. Espresso is a new Android test framework that lets you write concise, beautiful, and reliable UI tests quickly. The core API is small, predictable, and easy to learn - yet it is also open for customization. Espresso tests state their expectations, interactions, and assertions clearly without distracting boilerplate, custom infrastructure, or messy implementation details getting in the way. Tests run optimally fast - leave your waits, syncs, sleeps, and polls behind and let the framework gracefully manipulate and assert on your UI when it is at rest. Start enjoying writing and executing UI tests - try a shot of Espresso.

Update [October 2013]: Espresso is now open source:

Android UI Testing with Espresso and Google Cloud Test Lab

In this episode I take Espresso Test Recorder out for a spin and we record a UI test, run it on the device, look at the code it generated and then upload it to Google Cloud Test Lab to have the test run on 7 different devices.

I hope you'll enjoy following along!

GTAC 2015: Automated Accessibility Testing for Android Applications


Slides:

Casey Burkhardt (Google)

This talk will introduce the core accessibility affordances on the Android platform and illustrate some common developer pitfalls related to accessibility. You’ll learn about the new Android Accessibility Test Framework and its integration into the Espresso and Robolectric testing frameworks. Finally, you’ll learn how easy it is to add automated accessibility checking to your your existing Android project tests.

Frictionless Android testing: write once, run everywhere (Google I/O '18)

There are many testing tools available for Android, and selecting the right tool can be confusing. This session will showcase the Android Testing Support Library (ATSL) — a new set of testing APIs that allow developers to write tests of all sizes across different execution environments. These new APIs will make testing easy, reducing the cognitive load for developers and keeping them in the zone while rapidly iterating.

Automate Android App Testing with Robo

It’s important to continually monitor and test your apps functionality to ensure a quality user experience. In this video, we give you a quick explanation of what your test automation options are when it comes to your Android apps. We’ll discuss two ways to automate testing your apps - running Robo scripts in Firebase Test Lab, and Espresso tests using Android Studio.
