Thanks for your question! Since I haven’t seen your exact code or project setup, this is an educated guess based on common issues. Here are a few things to check: *1.JUnit Library* Make sure the JUnit library is added to your project's pom.xml. It's essential for writing and running tests. Refresh your project after adding JUnit so IntelliJ detects it. *2.Location of Test Files* Your test files should be in a special test folder, like src/test/java. Right-click the test folder in IntelliJ and mark it as "Test Sources Root" if it isn't already. *3.Test Methods* Ensure your test methods have the @Test annotation. Without it, IntelliJ won’t recognize the methods as tests. *4.Fix Errors* Make sure your code has no compilation errors. Errors in your test or main code can prevent IntelliJ from showing the green run button. *5.IntelliJ Configuration* Go to File > Project Structure > Modules and ensure JUnit is listed as a dependency. If IntelliJ is acting up, try clearing the cache: File > Invalidate Caches / Restart > Invalidate and Restart. *6.Alternate way* *Auto-generate Tests:* IntelliJ can create basic tests for you. Right-click the class you want to test, then go to Generate > Test. *Run Without Green Button:* You can right-click the test class or method in the editor and select Run.
I think you can continue with "temurin-17 Eclipse Temurin 17.0.12" .Temurin is a fully compatible, open-source build of the OpenJDK. It's essentially the same as the Oracle JDK, just with a different name and distribution.But keep in mind in that case you are using Java 17 .
Nice explanation, Thanks a lot sir!!
Most welcome!
Thank you so much mate!
