XCUITest vs. Appium vs. Espresso
In this blog, we compare XCUITest vs. Appium vs. Espresso, to help you determine the right framework for you.
XCUITest vs. Appium
The biggest difference between Appium vs. XCUITest is the platform. Appium works across platforms, while XCUITest only works on iOS for automated UI testing.
Also, Appium uses XCUITest driver for iOS apps. Appium XCUITest driver uses XCUITest under the hood. The Appium XCUITest driver supports all standard Appium capabilities.
Appium vs. Espresso
Here's a quick breakdown of Appium vs. Espresso. Appium uses any language, while Espresso uses Java. Appium is open source. Espresso was created by Google. Appium is more for black box testing, while Espresso is more for white box. The set up for Appium is difficult, while Espresso is relatively easy. Keep reading for a full comparison of XCUITest vs. Appium vs. Espresso.
Espresso vs. XCUITest
Here's a quick breakdown of Espresso vs. XCUITest. Espresso is a test automation framework for Android. XCUITest is a test automation framework for iOS. Both Espresso and XCUITest do white box testing. And both are very reliable for testing. XCUITest vs. Espresso vs. Appium.
Full Comparison: XCUITest vs. Appium vs. Espresso
Deciding which test framework to use can be difficult. Let's make it easier. Here are some mobile testing basics for your consideration.
The below comparison table highlights the key areas to consider when making this choice. We also break down XCUITest vs. Appium vs. Espresso below.
You can use Appium in any language. Espresso only works for Java. XCUITest only works for Swift / Objective C.
Appium supports both APK and IPA. However Espresso only supports APK. And XCUITest only supports IPA.
Appium doesn't require code. Espresso and XCUITest do require code.
Test Type / Instrumented
You would use Appium for black box testing. These tests are not instrumented. You would use Espresso and XCUITest for white box testing. These tests are instrumented.
Appium is slower, with a speed of 8t. XCUITest is faster at 2t, and so is Espresso at t.
Appium is the hardest to set up. XCUITest is easier to set up than Appium. But XCUITest is not as easy to set up as Espresso.
Espresso is the easiest framework for continuous integration (CI). It's harder to do CI with Appium. And it's the hardest to do CI with XCUITest.
Flakiness of Tests
Appium tests are very flaky. Espresso and XCUITest tests are much more reliable.
Appium uses an external object locator — X-path. Espress uses id (from R file). And XCUITest uses id, too.
Appium is typically used by QA Teams. Espresso is used by Android developers. And XCUITest is used by iOS developers.
Appium supports visual. Espresso and XCUITest do not.
When to Use Espresso, XCUITest, and Appium
There is no right or wrong answer when it comes to which automation framework you should chose.
While there are teams that choose to select one framework, there are many teams that will combine two. So, whether you should use Espresso, XCUITest, and/or Appium depends on your needs.
Espresso and XCUITest
You should use Espresso and/or XCUITest for:
- Teams with developer skills (developers, devTesters).
- Fast and reliable tests (Espresso and XCUITest run much faster and are more reliable over time).
- Pre-commit and CI testing (fast feedback validations).
It will be very interesting to see where the market will go in the next few years. I'm sure we will see significant increase in Espresso and XCUITest. We'll also see an increase in overall test automation execution. The same goes for an overall increase in fast feedback practices.
You should use Appium for:
- QA / automation teams.
- Full coverage with better validations.
- Nightly executions.
- Regression testing.
