IDE does not recognize Assumptions

Question

I am using Junit5, and my IDE (IntelijIdea) is not recognize Assumptions. I am actually do not know why, but may be there is some dependecy on Maven I do not connect into project. Below I will show you the sample of my code.

This is my Assumptions import.

import org.junit.jupiter.api.Assumptions;

And this is wrong code (I can not compile it, compiler does not know what is assumeTrue() )

@Test
@EnabledOnOs(OS.MAC)
void testInsertion() {
    assumeTrue(isServerUp); //That place is crashing
    assertThrows(NullPointerException.class, () -> Connection.insertTheInstance(person),
            "");

If you are familiar with this case then, please, share you knowledge) Many thanks!

JUnit 5 consists of several modules and assumptions are a part of `junit-jupiter-api` library, so you need this dependency in your pom file, e.g. the latest stable version is [5.6.2](https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api/5.6.2) — Yevhen Danchenko, Jun 02 '20 at 05:03

It's a import problem probably. Try:

  <dependency>
     <groupId>org.junit.jupiter</groupId>
     <artifactId>junit-jupiter-api</artifactId>
     <version>5.6.2</version>
     <scope>test</scope>
  </dependency>

Check if maven import is ok
Close your project in intellij
Delete your .m2 folder in your HOME directory (user/yourusername in windows, /home in linux)
Execute in a terminal in your project: mvn dependency:purge-local-repository clean.
Open your project again

If it's not ok yet, try the junit 4.12. Its have Assumptions too.

assumeTrue method is part of JUnit 4, but you can also use it in JUnit 5 through the

org.junit.jupiter.api.Assumptions class.

For intelliJ - Junit5 combination, make sure to import the following in your class:

import static org.junit.jupiter.api.Assumptions.assumeTrue;
