Why am getting this stacktrace? - java

After compiling my code I'm getting this Exception
java.lang.IllegalStateException: No instrumentation registered! Must run under a registering instrumentation.
I'm using eclipse IDE with ADT plugin.

Instrumentation tests need to be #RunWith(AndroidJUnit4.class) and not #RunWith(JUnit4.class)
Please check the documentation for more details,

The error says it all :

at MainTest.openGoogle(MainTest.java:15)
While working with Selenium v3.x you have to download geckodriver.exe from mozilla/geckodriver and place it in your system. Next you have to set the system property through the line System.setProperty() as follows and provide the absolute path of the GeckoDriver binary within your system as follows :
#Before
public void openGoogle()
{
System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
wd = new FirefoxDriver();
urll = "https://google.com";
}
Finally Instead of mentioning import org.junit.*; as per best practices mention the distinct exports as follows :
import org.junit.Before;
import org.junit.Test;
import org.junit.After;

Transform Scala future to CompletableFuture Error

I´m using this library (https://github.com/scala/scala-java8-compat) to transform a Scala Future to Java 8 CompletableFuture.
But running this example:
package utils;
import akka.dispatch.Futures;
import org.junit.Test;
import scala.concurrent.Future;
import java.util.concurrent.CompletableFuture;
import scala.compat.java8.FutureConverters;
import scala.concurrent.Promise;
public class ScalaFuture {
#Test
public void test() throws InterruptedException {
Promise promise = Futures.promise();
Future scalaFuture = promise.future();
CompletableFuture cf = FutureConverters.toJava(scalaFuture).toCompletableFuture();
cf.whenComplete((result, t) -> {
System.out.println(result);
});
promise.success("works");
Thread.sleep(1000);
}

While running JUnit test case for SV as code, I am getting the below error, even though all the SV as Code jars. the code is for create virtual services. In case i remove the line "forGet(URL)......;" the test case would pass, else it throws an error.

One of the SV jars, has a dependency on JDK1.8 jar(tools.jar), so we need to add JDK1.8 library in buildpath of the project.

Java Mocking FTP Session

I have an application that deals with ftp server, now I want to write some test, but I got trouble in the beginning, I am trying to mock the session factory but it throws exception and could not understand why, here is my code:
#Mock
SessionFactory<FTPFile> sessionFactory;
#Before
public void initMocks() {
MockitoAnnotations.initMocks(this);
DefaultFtpSessionFactory sf = new DefaultFtpSessionFactory();
sf.setHost(host);
sf.setPort(port);
sf.setUsername(username);
sf.setPassword(password);
Mockito.when(sessionFactory.getSession()).thenReturn((Session<FTPFile>) new CachingSessionFactory<FTPFile>(sf));
}
and here is the exception I got:

Can someone tell me where I did it wrong? :/

If you are looking to test your FtpClient you could use MockFtpServer is very simple to configure and use in tests.
The MockFtpServer project provides mock/dummy FTP server
implementations that can be very useful for testing of FTP client
code. Two FTP Server implementations are provided, each at a different
level of abstraction.
