IntelliJ, Junit 4 Maven - Cannot resolve symbol assertEquals

Maven JUnit 4.12 dependency is there. Doesn't work with both static and without it. assertEquals is in red/not resolved. Assert. does not show methods.

Tried by adding assertJ library too as dependency. Same issue. In code, I do Assertions.. It doesn't show any methods.

The issue isn't the import of Assert (which is fine), but the fact you have the call to Assert.assertEquals outside of any method - and you can't have such a statement directly under a class. Move it up into requestUsZipExtractPlaceName, and you should be fine:

@Test
public void requestUsZipExtractPlaceName(){

    String placeName =
            given().
            spec(requestSpec).
            when().
            get("us/90210").
            then().
            extract().
            path("places[0].'place name'");

    Assert.assertEquals("Beverly Hills", placeName); // Move here, inside the method
}

// Instead of here
