+## Setting up XCUITests
+
+Sometimes, XCUITests are useful when integration testing a plugin that has native UI on iOS (e.g image_picker, in_app_purchase, camera, share, local_auth etc). Most of the time, XCUITests are not necessary, consider using [integration_test](https://pub.dev/packages/integration_test) if the tests are not focused on iOS system UI.
+
+If XCUITests has always been set up for the plugin, a RunnerUITests folder under `<the_plugin>/example/ios` directory can be found.
+If XCUITests has not been set up for the plugin, follow these steps to set it up:
+
+1. Open <path_to_plugin>/example/ios/Runner.xcworkspace using XCode.
+1. Create a new "UI Testing Bundle".
+1. In the target options window, populate details as following, then click on "Finish".
+  * In the "product name" field, type in "RunnerUITests" (this is the test target name our CI looks for.).
+  * In the "Team" field, select "None".
+  * In the Organization Name field, type in "Flutter". This should usually be pre-populated.
+  * In the organization identifer field, type in "com.google". This should usually be pre-populated.
+  * In the Language field, select "Objective-C".
+  * In the Project field, select the xcodeproj "Runner" (blue color).
+  * In the Target to be Tested, select xcworkspace "Runner" (white color).
+1. A RunnerUITests folder should be created and you can start hacking in `RunnerUITests.m`.
+1. To enable the test on CI, the plugin needs to be removed from the "skip" list:
+  * Open `./cirrus.yml` and find PLUGINS_TO_SKIP_XCTESTS.
+  * Remove the plugin name from the list.
+
 ## Running the tests

+### XCTests (iOS)
+
+XCUnitTests are typically configured to run with cocoapods in this repo. To run all the XCUnitTests for a plugin:
+
+```console
+cd ios
+pod lib lint --allow-warnings
+```
+
+XCUITests aren't usually configured with cocoapods in this repo. They are configured in a xcode workspace target named RunnerUITests.
+To run all the XCUITests in a plugin, follow the steps in a regular iOS development workflow [here](https://developer.apple.com/library/archive/documentation/DeveloperTools/Conceptual/testing_with_xcode/chapters/05-running_tests.html)
+
+For convenience, a [flutter_plugin_tools](https://pub.dev/packages/flutter_plugin_tools) command `xctest` could also be used to run all the XCUITests in the repo:
+
+```console
+pub global activate flutter_plugin_tools
+cd <path_to_plugins>/packages
+pub global run flutter_plugin_tools xctest --target RunnerUITests --skip <plugins_to_skip>
