JUnit 5 obsolete assertions

Reports any calls to methods from the junit.framework.Assert, org.junit.Assert, or org.junit.Assume classes inside JUnit 5 tests.

Although the tests work properly, migration to org.junit.jupiter.api.Assertions/org.junit.jupiter.api.Assumptions will help you avoid dependencies on old JUnit version.

Example:

  import org.junit.Assert;
  import org.junit.jupiter.api.Test;

  public class MyTest {
    @Test
    public void simpleTest() {
      Assert.assertEquals(4, 2 + 2);
    }
  }

After the quick-fix is applied:

  import org.junit.jupiter.api.Assertions;
  import org.junit.jupiter.api.Test;

  public class MyTest {
    @Test
    public void simpleTest() {
      Assertions.assertEquals(4, 2 + 2);
    }
  }
