 - *IntelliJ* - IntelliJ idea can import and build gradle-based projects out of the box. It will default to running tests by calling the gradle wrapper, and while this works, it is can be a bit slow. If instead you configure IntelliJ to use its own built-in test runner by (in 2024 version) navigating to settings for Build Execution & Deployment/Build Tools/Gradle (under File/Settings menu on some platforms) and selecting "Build and Run using: IntelliJ IDEA" and "Run Tests using: IntelliJ IDEA", then some tests will run faster. However some other tests will not run using this configuration.
