The import org.junit.jupiter cannot be resolved

Question

Hey its the first time i use JUnit with Java and i\'m not sure how to set it up inside Visual studio Code. I tried to put Junit-4.13.jar inside my a lib file in the root directo

Answer 1

There were 2 main issues with this configuration:

• JUnit 4 dependency jar was used while in the source code imports from JUnit 5 API were used

• Tests resided in the same location as sources, while the dependencies defined via Gradle/Maven for tests limit the scope to src/test/java roots.

In a non-Gradle project the issue was fixed by adding the proper JUnit 5 dependencies to the module.

In the Gradle project the issue was fixed by moving the test class from src/main/java to src/test/java.

Sample Gradle project is available on GitHub.

More details about using JUnit 5 can be found in the official documentation.
