React Native UI Test

This component runs all the UI tests in your project written with Detox integration. When this step is completed, it generates a test report file in e2e-report.xml format. You can view these test results in detail using Appcircle's Test Report component.

For detailed information for continuous testing, please visit our React Native Continuous Testing documentation.

To generate detailed Test Reports. Please visit our Test Reports Component documentation.

Java Version

The default Java version in Appcircle's build stacks is Java 11. If your project requires a higher or lower Java version, please see the How to Change Java Version document. On the other hand, you can see all details for build stacks both iOS and Android with this documentation.

Prerequisites

The workflow steps that need to be executed before running the React Native UI Test workflow step in both iOS and Android platforms, along with their respective reasons, are listed in the table below.

For iOS

Prerequisite Workflow Step	Description
Git Clone	Clone the selected repository to the build machine.
Install Node	This step will install Node modules for your application.
NPM/Yarn Commands	This step installs the NPM or Yarn package manager to install specific dependencies for your React Native applications.
Cocoapods Install	This step installs all the dependencies of the pod file.

info

If your CocoaPods dependencies are embedded in the project, you do not need to use the CocoaPods Install step to run UI tests.

For Android

Prerequisite Workflow Step	Description
Git Clone	Clone the selected repository to the build machine.
Install Node	This step will install Node modules for your application.
NPM/Yarn Commands	This step installs the NPM or Yarn package manager to install specific dependencies for your React Native applications.
Wait for Android Emulator	This step waits for the Android Emulator to boot. You must use this step before running any UI tests.

React Native UI Test for Android

For Appcircle Cloud, you need to use Appcircle Linux Pool (x86_64) to run your UI tests on the Android platform. Since Appcircle Standard macOS Pool (arm64) is based on Apple Silicon's virtualization technology, it does not support running Android emulators. If your organization has self-hosted pools, you can choose and use any pool that has bare-metal machines or VMs that support nested virtualization. For more information, please follow the Build Configuration and Android Build Infrastructure documentations.

Android Emulator

React Native UI Test component works according to the device given in the project configurations. To change the emulator device or install a new device, please follow the Emulator documentation.

Step Rule

If any workflow steps fail, Appcircle automatically skips the next steps. However, it is possible that some of your tests may fail. If you have a failing test, Appcircle will break the pipeline. If you want your pipeline not to break even if an error occurs in this step (especially for exporting test reports), you should activate the following option:

• Continue with the next step even if this step fails to ON

Input Variables

This step contains different variables. It needs these variables to work. The table below gives explanations of these variables.

Variable Name	Description	Status
$AC_REPOSITORY_DIR	Specifies the cloned repository directory. This path will be generated after the Git Clone step.	Required
$AC_OUTPUT_DIR	This variable specifies the path of the artifacts that will be generated after the build is complete.	Required
$AC_RN_DETOX_CONFIGURATION	Specify the detox configuration name to used when building and running the tests.	Required
$AC_RN_DETOX_TEST_ARGS	Specify the Detox extra arguments to add the test command. The arguments will be executed by appending detox test --configuration<configname> to the end of the command. The default value is --take-screenshots all For more information, see the Detox test CLI options.	Optional

Detox Configuration

To able to run your test successfully, you must specify the Detox Configuration in the $AC_RN_DETOX_CONFIGURATION. If you do not specify a specific configuration, UI tests will throw an error because of the configuration not found.

Example Configuration

  configurations: {
    'ios.sim.debug': {
      device: 'simulator',
      app: 'ios.debug',
    },
    'ios.sim.release': {
      device: 'simulator',
      app: 'ios.release',
    },
    'android.emu.debug': {
      device: 'emulator',
      app: 'android.debug',
    },
    'android.emu.release': {
      device: 'emulator',
      app: 'android.release',
    },
  },

For more information, please visit Continuous Testing documentation.

How to Download Screen Shots

The Appcircle interface does not support displaying screenshots generated from UI tests in React Native projects. All screenshots created as a result of these tests are exported to Download Artifacts as test_attachments.zip. You can access the relevant screenshots in Download Artifact and download them directly.

caution

To view the output artifacts on the Download Artifacts page, please ensure that the Export Build Artifacts step is included in your Workflow after this step.

Output Variables

The outputs resulting from the operation of this component are as follows:

Variable Name	Description
AC_TEST_RESULT_PATH	The output path for the e2e-report.xml file. This environment variable can be utilized in subsequent steps.
