In order to mock java.net.URL class through mockito library, you need to perform the following steps:

• Create a directory, named 'mockito-extensions' in src/tests/resources directory.
• Create text a text file in the folder, named org.mockito.plugins.MockMaker and put mock-maker-inline text into the file.
• you can mock the class like the following:

code:

package myproject;

import org.junit.Test;

import java.net.HttpURLConnection;
import java.net.URL;
import static org.junit.Assert.*;
import static org.mockito.Mockito.*;

public class Test {
    @Test
    public void test() throws Exception {
        URL url = mock(URL.class);
        HttpURLConnection huc = mock(HttpURLConnection.class);
        when(url.openConnection()).thenReturn(huc);
        assertTrue(url.openConnection() instanceof HttpURLConnection);
    }
}
