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;
Here you can find a detailed discussion on NoClassDefFoundError

I am trying to migrate my codebase beyond Java 8, and Ignite is now the only dependency holding me back. I have tried adding --add-module to my runner, but I can't seem to find what is needed to make Ignite work with JDK 9.
The same error is with Ignite versions 2.4.0 and 2.5.0.
Any help would be much appreciated!
Try adding the following parameters when launching Java:
--add-exports=java.base/jdk.internal.misc=ALL-UNNAMED
--add-exports=java.base/sun.nio.ch=ALL-UNNAMED
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);
}
I have this error

I found a solution - https://github.com/kaeawc/testable-active-android/blob/master/app/src/test/java/io/kaeawc/activeandroidapp/model/ActiveAndroidModelSpec.java
But the fact is that in addition I need PowerMockRunner and RobolectricGradleTestRunner. The project uses the class Application (it is stored on the Component Dagger). Options from here did not help.
In the first case:
#RunWith(RobolectricGradleTestRunner.class)
#Config(constants = BuildConfig.class, manifest = "src/test/TestManifest.xml", sdk = Build.VERSION_CODES.LOLLIPOP)
#PowerMockIgnore({"org.mockito.*", "org.robolectric.*", "android.*"})
#PrepareForTest({ Cache.class, TableInfo.class, Context.class, ContentResolver.class, ContentProvider.class, ContentValues.class })
#SuppressStaticInitializationFor("com.activeandroid.content.ContentProvider")
public class BaseTest {
#Rule
public PowerMockRule rule = new PowerMockRule();
#Test
public void setup() throws Exception {
PowerMockito.mockStatic(ContentProvider.class);
PowerMockito.when(ContentProvider.createUri(Model.class, 0l)).thenReturn(null);
assertTrue(ContentProvider.createUri(null, null) == null);
}
}

What should I do?
For the exception "org.powermock.api.mockito.ClassNotPreparedException: "
You could try to put this annotation on top of the class declaration or test method.
#RunWith(PowerMockRunner.class)
#PrepareForTest(CommPortIdentifier.class)
All the best,
So here is the class and method I want to create a test for:
public class RequestController {
private GetAllInter getAnalytics;//This is an interface
#RequestMapping(value ="",method=RequestMethod.GET)
public String getAllAnalytics(){
log.debug("Processing request for all analytics");
String result;
try {
result = getAnalytics.getAll();
} catch (Exception e) {
result = "Could not retrieve full list of analytics";
log.error(result,e);
}
return result;
}
Specifically I want mock the getAnalytics.getAll() so it returns a String I already defined. Instead of the method doing its thing. This is my code:
public class RequestControllerTest extends Mockito{
private String allAnalyticsStr = "Hello";
#Test
public void testGetAllAnalytics(){
GetAllInter getAll = mock(GetAllInter.class);
when(getAll.getAll()).thenReturn("what");
RequestController requestController = new RequestController();
assert(requestController.getAllAnalytics().equals("Hello"));
}
And when I try to run the test this is the error im getting:
16:17:03.240 [main] DEBUG dar.RequestController - Processing requst for all analytics
16:17:03.248 [main] ERROR dar.RequestController - Could not retrieve full list of analytics

Any idea what I'm doing wrong? Is there another way to do this? Is it because I am mocking an interface of the class and not the class itself?
You need to replace RequestController#getAnalytics field with mocked GetAllInter instance before executing test.
GetAllInter getAll = mock(GetAllInter.class);
when(getAll.getAll()).thenReturn("what");
That statement doesn't effect RequestController's getAnalytics instance behavior until you set it as RequestController's field.
I found similar question
mockito - mocking an interface - throwing NullPointerException
The easiest way is provide setter for RequestController#getAllanalytics or provide RequestController constructor taking GetAllInter argument.
But using #InjectMocks would be nicer solution since you don't need to modify the RequestController class for testing.
