How to start

## Run tests ### Unit Tests Run unit tests which check each method and commands, URL, using the webmock.

bash $ bundle install $ bundle exec parallel_test test/unit/

Functional Tests

Run functional tests which require the Appium server and real device, Simulator/Emulator.

  • Start Appium server bash $ npm install -g appium opencv4nodejs $ appium --relaxed-security # To run all tests in local

  • Conduct tests bash $ bundle install $ rake test:func:android # Andorid, uiautomator2 $ AUTOMATION_NAME_DROID=espresso rake test:func:android # Andorid, uiautomator2 $ rake test:func:ios # iOS

Real device for iOS

  • You should pre-install UICatalog in iOS with a particular bundleId
    • Set the bundleId instead of app in test/test_helper#ios

```bash # Create derivedDataPath in “/tmp/#org_id” and reuse xctestrun in the directory $ REAL=true BUNDLE_ID=’target-bundleid’ WDA_BUNDLEID=”ios.appium.WebDriverAgentRunner” ORG_ID=XXXXXXX rake test:func:ios

Run with xcconfig file. The template is in ‘test/functional/ios/temp.xcconfig’

# The PROVISIONING_PROFILE is in ‘~/Library/MobileDevice/Provisioning\ Profiles/’ $ REAL=true XCODE_CONFIG_FILE=’/path/to/xcconfig’ ORG_ID=XXXXXXX rake test:func:ios ```

Run parallel tests with parallel_tests gem

#### Android

# Generate 3 emulators. Running 3 emulators require much machine power. # It requires an image which is for Google Play and x86 CPU architecture's image. $ bundle exec rake android:gen_device $ PARALLEL=1 bundle exec parallel_test test/functional/android -n 3

  • Create iPhone simulators named iPhone Xs Max- 8100 and iPhone Xs Max - 8101
  • Run iOS functional tests with below command

$ PARALLEL=1 bundle exec parallel_test test/functional/ios -n 2


  • Runs on CI environment (on Azure)
    • Non IGNORE_VERSION_SKIP or IGNORE_VERSION_SKIP=true runs all tests ignoring skip them by Appium versions
    • IGNORE_VERSION_SKIP=false skips the following tests if the Appium version is lower than the requirement

$ IGNORE_VERSION_SKIP=true CI=true bundle exec rake test:func:android

Run a test case

  1. Launch the Appium server locally.
  2. Run the following script.
  • test.rb ```ruby require ‘rubygems’ require ‘appium_lib_core’

    opts = { desired_capabilities: { # or { caps: …. } platformName: :ios, platformVersion: ‘11.0’, deviceName: ‘iPhone Simulator’, automationName: ‘XCUITest’, app: ‘/path/to/’ }, appium_lib: { wait: 30 } } @core = Appium::Core.for(opts) # create a core driver with opts @driver = @core.start_driver

    # Launch iPhone Simulator and @driver.find_element(:accessibility_id, ‘some accessibility’) # find an element ```

  • Run the script ```bash # shell 1 $ appium –log-level warn:error # show only warning and error logs

    # shell 2 $ ruby test.rb ```

More examples are in test/functional
