Testing will be more efficient when testers and developers work in collaboration. Especially when it comes to automated testing, we have many challenging points that should be solved with the help of the other team members. This is a basic explanation of the cross-functional team. For mobile application automated end-to-end testing, this cross-functional team approach can be easily applied by contributing the same code base so native toolings give us this. This can increase the quality of the tests code and the framework by the feedback from the developers, and increase the quality of the tests by the feedback from the testers.
In this post, I want to give some idea about the benefits of using native mobile automation toolings such as Espresso and XCUITest.
What is Native Tooling
Native mobile automation toolings are integrated libraries to the mobile application development framework so that developers can write UI tests for the products under development. Native toolings are part of the development frameworks so it is always guaranteed that the tools are always up to date with the development frameworks and upcoming new features. Native toolings use the same development languages as the development frameworks so the contribution to tests and the application development would be similar approach and strategy.
Since we are talking about two major mobile device operating systems, we are just focusing on Android and iOS. Native mobile automation toolings are
Android - Espresso
iOS - XCUITest
How Native Toolings Work
Native tools work natively, which means that they are providing direct methods via APIs that are done inside the development project globally. Interactions are made by directly calling the UI objects inside project architecture by the APIs.
So these are the main benefits:
APIs know the state of the objects
We are free to use tools as black-box as well as contribute the development code as white-box
We are free to reach the UI objects
If the app is the Matrix, native tools are the agents inside the matrix
How Espresso Works
Espresso is a test automation tool developed by Google for Android UI Tests. Espresso is open-source, very stable, and there are many frameworks have been developed around Espresso.
It has a full feature-set of Junit that works with Espresso
Android Studio provides everything you need
It provides white-box testing
What Google says about it
How XCUITests Works
XCUITest is native and inside the app source code with different target
XCode provides everything you need
It provides white-box testing
XCTest provides everything you need for testing capabilities
Accessibility provides UI interaction for all kinds of XCode product
Benefits: Handling Objects
Native toolings are inside the projects so no need to worry about the use of external tool to get the related objects.
Espresso and XCUITest provides the following benefits
- APIs provide methods for all kinds of object
- Methods are always up-to-date with the latest improvements/updates
- Freely update the source code for the sake of UI-test
Benefits: IDEs are Friendly
Benefits: Servers -- NO
Performance is very important when you grow and have to handle hounderents tests. The main point for the performance is how much time your tests require for running them locally and in cloud services
Simple UI frameworks interact with the objects so no need to translate with servers
Native tooling know the state of the elements so no need to check them regularly
Automation code is inside the test package so no need to handle it differently while testing on the cloud. This reduces the time drastically
Benefits: Team Building Around Quality
Better performance from an automation project can be only get when the developers and testers work cooperatively. Developers are always result-oriented people so they focus on the development of the features, but the QAs/SDETs must be keen on the quality. This quality not only the product quality but also the quality of the tests, process, and documentation. This can be achieved by cross-functional team building.
Cross-functional-team requires the followings:
Shared common knowledge, every team member should know basics about
What is being built
How things are developed
How things are being tested
The absence of one person from a role can be filled by another role
QA/SDET can be a developer
Developer can be QA/SDET
