Exception while running in Junit - java

I am trying to do unit test for JSONException. Below it's the code:
public void testException(JSONObject jsonObj){
try{
String test = jsonObj.getString("test");
}catch(JSONException e){
}
}
But in the Unit tests when I give the below it throws a different exception:
#Test (expected=JSONException.class){
mymockClass.testException(jsonObj);
}
java.lang.AssertionError: Expected exception: org.codehaus.jettison.json.JSONException

Its because test expects that exception will be actually thrown out of test method, but you are catching it - thats why you have "expected exception has not been thrown" exception. Remove try-catch block and add throws to method signature.
public void testException(JSONObject jsonObj) throws JSONException{
String test = jsonObj.getString("test");
}

That code take me an error, i try with Spring Boot and Mockito, Junit4:

exception optaining signature: Could not verify signature

I have the following code, which is taken from ShowSignature example from PDFBox 2. I'm running five tests in which it is called, 4 of them pass without problem (no signature, single signed, double signed, expired signature), but the fifth one is wit Eliptic Curve and it fails.
The fun part is that it passes when I start the JunitTest only on the test-class, but fails as soon as I'm starting it on package or project level.
I would assume something befor the test class is interfering, but can't find a hint what it could be. I checked bouncycastle (1.54 is always used), the java jdk is at any point correctly used (jdk1.8.0_181).
I'm checking the for an exception to be thrown (ERROR_VERIFYING_PDF_SIGNATURE), it is thrown in the classtest, but a different one when starting on higher level.
Error occurs in if (signerInformation.verify(new JcaSimpleSignerInfoVerifierBuilder().build(certFromSignedData)) and has this stack trace:
java.lang.AssertionError:
Expected: (an instance of de.bdr.rt.core.common.api.BusinessLogicException and exception with message a string containing "Die Signatur des PDF-Dokuments konnte nicht verifiziert werden.")

This is a shortcoming of the PDFBox example. Please change
signerInformation.verify(new JcaSimpleSignerInfoVerifierBuilder().build(certFromSignedData));
to
signerInformation.verify(new JcaSimpleSignerInfoVerifierBuilder().setProvider(BouncyCastleProvider.PROVIDER_NAME).build(certFromSignedData));
you may have to register BC as provider:
Security.addProvider(new BouncyCastleProvider());

Failed to invoke PACT method

I have this snippet of code, while trying to create a pact file for my service, but it keeps throwing Failed to invoke pact Method. However, when I run the normal client request, it returns a json object, but when trying to run the pact test, it fails. Below is the snippet of the Test class
public class WhatPrimesTest {
#Rule
public PactProviderRuleMk2 provider = new PactProviderRuleMk2("PrimeService", "localhost", 81, this);
#Pact(provider = "PrimeService", consumer = "PrimeServiceClient")
public RequestResponsePact createPact(PactDslWithProvider builder) {
Map<String, String> headers = new HashMap();
headers.put("Content-Type", "application/json");
DslPart etaResults = new PactDslJsonBody()
.stringType("requestedGtin", "4211")
.integerType("nodeId", 6132)
.eachLike("gtinList")
.eachArrayLike("AVAILABLE", 4322)
.asBody();
return builder
.given("There is a prime gtin 4211 from node 6132")
.uponReceiving("A request for gtinList")
.path("/primeService/6132?upc=4211")
.method("GET")
.willRespondWith()
.status(200)
.headers(headers)
.body(etaResults).toPact();
}
#Test
#PactVerification("PrimeService")
public void doTest() {
System.setProperty("pact.rootDir", "../pacts"); // Change output dir for generated pact-files
String gtinExpected = "00000000012348";
String gtinList = new WhatPrime(provider.getPort()).checkEta(6132, "4211");
System.out.println("According to test eta=" + gtinList);
//assertTrue(gtinList.);
//assertArrayEquals("00000000012348", gtinExpected);
}
}
And I get this error when I try to run this test code.

Java with mockito fails

I have following method in my service to mock AWS sqs
#Override
public Message recieveMessage(String queueUrl) {
Objects.requireNonNull(queueUrl);
ReceiveMessageRequest request = new ReceiveMessageRequest().withQueueUrl(queueUrl).withMaxNumberOfMessages(1);
ReceiveMessageResult receiveMessageResult = this.sqsClient.receiveMessage(request);
// As per the spec, we need to return only one message.
return receiveMessageResult.getMessages().get(0);
}
#Override
public int getMessageCount(String queueUrl) {
GetQueueAttributesResult queueAttributes = sqsClient.getQueueAttributes(queueUrl, Arrays.asList("ApproximateNumberOfMessages"));
return Integer.valueOf(queueAttributes.getAttributes().get("ApproximateNumberOfMessages"));
}
and following are my test cases for these methods using mockito are failing with NPE.
#Test
public void testRecieveMessage() {
Message message = new Message();
message.setBody("Message Body");
List<Message> messages = new ArrayList<>();
messages.add(message);
ReceiveMessageResult result = new ReceiveMessageResult();
result.setMessages(messages);
when(mock(ReceiveMessageResult.class).getMessages()).thenReturn(messages);

Am I missing something?
Here is what your code does:
ReceiveMessageRequest request = new ReceiveMessageRequest().withQueueUrl(queueUrl).withMaxNumberOfMessages(1);
ReceiveMessageResult receiveMessageResult = this.sqsClient.receiveMessage(request);
So it creates a new request, and passes ths new request to sqsClient.receiveMessage().
Here's how you test that:
when(this.amazonSQSClient.receiveMessage(mock(ReceiveMessageRequest.class))).thenReturn(result);
So your test tells th mock client to return result when receiveMessage() is called with a mock ReceiveMessageRequest.
So that can't work. The mock ReceiveMessageRequest is not equal to the new request used in the code. You need to do something like
when(this.amazonSQSClient.receiveMessage(any(ReceiveMessageRequest.class))).thenReturn(result);
So that, whetever the request passed to receiveMessage, the mock client returns the result.
Regarding your second question:
this.amazonQueueService.getMessageCount(anyString());
doesn't make sense. You need to call your method with a real, given string.

And this is the code producing it:
#RunWith(RobolectricTestRunner.class)
public class GameStatusHandlerTest {
#Mock
GraphicsRenderer renderer;
private GameStatusHandler handler;
private ArrayList<String> list = new ArrayList<>();
Context context;
#Before
public void setUp(){
context = Robolectric.application.getApplicationContext();
handler = new GameStatusHandler(context, renderer);
list.add(0, "level0.txt");
}
#Test
public void testLoadGame(){
try {
handler.loadGame(list);
} catch (Exception e) {
e.printStackTrace();
}
assertTrue(handler.getCurrentLevel() == 0);
}
Through the stactrace it's clear that the code which causes this error is a call to this method, which is a static method in the MatrixFileReader class.
public static int[][] getMatrix(Context context, String name) throws Exception {
int[][] marbles = getMatrix(context.getAssets().open(name));
return marbles;
}
}
Since the stacktrace doesn't go deeper, i guess that the problem is in the context.getAssets.open() method, but i can't figure out the reason, since the pure code is running perfectly onto both the emulator and a real device.
I am probably missing something in the test, which i am trying to run as a junit test.
As mentioned above, use RobolectricGradleTestRunner instead of RobolectricTestRunner.
Then make sure that the file you are reading is present in the assets folder of the source code: src/main/assets.
If you don't want to put it in your test folder, then you will have to specify the test asset folder as one of the asset source in your gradle build like this:
sourceSets.main {
assets.srcDirs = ['src/main/assets', 'src/test/assets']
}
Also your mock GraphicsRenderer won't be initialized with the Mock annotation as you are not using the MockitoJUnitRunner class. You have to initialize it like this in setUp().
renderer = Mockito.mock(GraphicsRenderer.class);
Please specify android manifest via #Config annotation to your test
