I have a JUnit Test that starts my spring boot appcliation (Application.java).
@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class AppclaitionTest {
@Test
public void contextLoads(){
Application.main(new String[]{});
}
}
If I run the JUnit test, Application is successfully starting up, but not accessible through url
Application Logs:

When I tried to access the application through url ‘http://localhost:8080/process‘, It says Site can’t be reached.

Answer
Why would you do such thing? This should be a unit test and the flow of the test should be the following: Start the application -> Call your controller endpoint -> assert that a specific text/element on that page is present -> Shut down the application.
Start the application : @RunWith(SpringRunner.class) doing this for you, no need to start is manually.
Shut down the application : At the end of your test class Spring boot does this for you (That’s why you cant access your app in the browser)
