# GitHub Actions Workflow for launching UI tests on Linux and Mac in the following steps:
# - Prepare and launch IDE with your plugin and robot-server plugin, which is necessary to interact with the UI.
# - Wait for IDE to start
# - Run UI tests with a separate Gradle task.
#
# Please check https://github.com/JetBrains/intellij-ui-test-robot for information about UI tests with IntelliJ Platform.
#
# Workflow is triggered manually.
