I have a file testPristineCopy.xlsx in ..\src\test\resources folder. In my unit test< i try and access it like this:
InputStream testInputStream = this.getClass().getResourceAsStream("/testPristineCopy.xlsx");
I get an error for this line when I tried running the unit test using JUnit. The stack trace is below:

Any idea what the problem is? I need these resources to be accessible for the test cases when they are run on Jenkins.
You can use the relative path to access any resource file under src/test/resources folder. Something like this.
InputStream testInputStream = new FileInputStream(new File("src/test/resources/testPristineCopy.xlsx"));

What I got, is a couple of methods to generate AES key. I'm doing test cases over it, but when I try to pass a test to verify it returns the String of the AES key, it fails.
The method to call is:
public String getAESString() {
return Base64.encodeToString(this.aesKey.getEncoded(), Base64.DEFAULT);
}
and the test: (the setupAES just call the generate AES method that it's already tested)
#Test
public void getAESString() throws NoSuchAlgorithmException {
setupAes();
assertNotNull(cryptoMancer.getAESString());
}
But I know, that the method getAesString, is working fine, because I'm using it a test Activity, and I can used it, without problems.
How can I avoid this error? (I mean, how I pass the test)
The error log i'm getting is:

Image, that shows the method working perfect in the app:
One of my test cases is getting NoSuchMethodError. I've removed getExceptionHandler() method from the project so this method shouldn't be detected at all. This is the only test case with this error.

I don't know how to tell the compiler that getExceptionHandler() doesn't exist any more.
Thanks
The problem is not in your test! The test calls ISOPPCServiceHelper which still uses the method getExceptionHandler(). You have to recompile that class. Always use clean test of your build system after refactorings to make sure everything is compiled right (hopefully you have one, otherwise rebuild project of your IDE should do the job).
I use ActiveAndroid library for working with the database. The automatic test crashes with an error when I create an object model.

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);
}
}
Stacktrace:

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.
In Java I am using FutureTask to run a Callable asynchronously via Executor. In order to check if an error occurred from the calling thread, I need to throw potential exceptions from the Callable. This however, leads to the stacktrace printed out to System.out (I debugged and this happens inside Unsafe.unpark(Thread) from LockSupport.unpark(Thread)).
Any ideas how I could prevent this?
I already log the exception to a real logger before (via SLF4J) and never want direct stacktraces on System.out.
Update: I think I already pointed out the relevant information but to clarify all the questions:
This test case can reproduce the Problem (Method testTransferStreamAsyncCallbackFail()):
https://github.com/m-m-m/util/blob/master/io/src/test/java/net/sf/mmm/util/io/base/StreamUtilTest.java
The implementation used is this:
public AsyncTransferrer transferAsync(InputStream inStream, OutputStream outStream, boolean keepOutStreamOpen, TransferCallback callback) {
StreamTransferrer transferrer = new StreamTransferrer(inStream, outStream, keepOutStreamOpen, callback);
AsyncTransferrerImpl task = new AsyncTransferrerImpl(transferrer);
this.executor.execute(task);
return task;
}
I debugged through the eniter code and it is definetly not my code that logs to the console. This is done in the JDK as I tried to explain.
Additional Update to answer the questions:
The executor I am using is Executors.defaultThreadFactory()
As you can see here:
https://github.com/m-m-m/util/blob/master/core/src/main/java/net/sf/mmm/util/concurrent/base/SimpleExecutor.java#L30
https://github.com/m-m-m/util/blob/master/io/src/main/java/net/sf/mmm/util/io/base/StreamUtilImpl.java#L165
The output is the stacktrace of the Exception that I throw in my test from the Callable:
java.util.concurrent.ExecutionException: net.sf.mmm.util.io.api.RuntimeIoException: IO: An unexpetected error has occurred while copying data!
