In IntelliJ, you can run JUnit tests by navigating to the test class, right-clicking, and selecting “Run ‘TestClassName’.” Alternatively, you can use the IntelliJ toolbar or configure a JUnit run configuration.

JUnit tests can be run in Eclipse by selecting the test class or method, right-clicking, and choosing the “Run As” option. Eclipse provides an integrated environment for Java development and testing.
