Junit5 shows 0% coverage in Intellij help on cover the line

[Hrishi50]

Hi All,

We have created Junit5 class for the below code.

We covered all line except 40, 47 and 48, can anyone help to cover line no 40, 47 and 48?

Test Class:-

import io.wcm.testing.mock.aem.junit5.AemContext;
import io.wcm.testing.mock.aem.junit5.AemContextExtension;
import org.apache.sling.api.resource.Resource;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;

import static org.junit.jupiter.api.Assertions.assertEquals;
@ExtendWith(AemContextExtension.class)
public class RedirectionModelTest {

    AemContext context = new AemContext();
    @BeforeEach
    public void setUp() throws Exception{

        context.create().page("/content/mykp/en");
        Resource resource = context.resourceResolver().getResource("/content/mykp/en");
        context.request().setAttribute("redirectURL", "/content/mykp/homepage");
        context.currentResource(resource);
        context.request().adaptTo(RedirectionModel.class);

    }

    @Test
    public void init() {
        assertEquals("/content/mykp/homepage.html",context.response().getHeader("location"));
    }
}

For catching exception can you try something like below? Not a direct solution to your problem just an example

@Test
	void testinitException() throws Exception {
		when(myModel.method()).thenThrow(NullPointerException.class);
		
		assertNotNull(mymodel);
	}

Basically in the test method we throw an exception explicitly and make sure its caught and handled
