问题 In continuing to this answer I wrote a unit test to verify that in case of error, the stack will be printed in the log file. The tested method: import org.slf4j.Logger; import org.slf4j.LoggerFactory; private final Logger logger = LoggerFactory.getLogger(getClass()); public long getFq(String fi) { try { return calcSomeThing(fi.toLowerCase()); } catch (Exception e) { logger.error("unable to calculate SomeThing. Error: " , e); return -1; } } The unit test: import ch.qos.logback.classic.Level;

问题 I am writing an integration test using mockito. The unit under test is connected to a mocked object (objA) through an interface. The functionality that I am trying to mimic happens when the mocked objected fires an event and the unit under test is listening to it. The interface: public interface MyInterfaceAPI{ void fireyMyEvent(String msg); } The unit under test: public class UnitUnderTest{ ObjA objA; public UnitUnderTest(ObjA objA_t) { objA = objA_t; objA.addMyListener(new addMyHandler());

问题 I'm relatively new to Java and I'm asking to write test of JSON response server. I found JSONassert very useful but I didn't succeed to write the method getRESTData . Anybody can help please? @Test public void testGetFriends() throws JSONException { JSONObject data = getRESTData("/friends/367.json"); String expected = "{friends:[{id:123,name:\"Corby Page\"}" + ",{id:456,name:\"Solomon Duskis\"}]}"; JSONAssert.assertEquals(expected, data, false); } 回答1: You can get the data as String and pass

问题 I'm testing a service layer and not sure how to mock ObjectMapper().readValue in that class. I'm fairly new to mockito and could figure out how to do it. The following is my code, service.java private configDetail fetchConfigDetail(String configId) throws IOException { final String response = restTemplate.getForObject(config.getUrl(), String.class); return new ObjectMapper().readValue(response, ConfigDetail.class); } ServiceTest.java @Test public void testgetConfigDetailReturnsNull() throws

问题 I want to write unit tests for my spring controller. I'm using keycloak's openid flow to secure my endpoints. In my tests I'm using the @WithMockUser annotation to mock an authenticated user. My problem is that I'm reading the userId from the token of the principal. My unit test now fails because the userId I read from the token is null; if (principal instanceof KeycloakAuthenticationToken) { KeycloakAuthenticationToken authenticationToken = (KeycloakAuthenticationToken) principal;

问题 I am writing a unit test for a FizzConfigurator class that looks like: public class FizzConfigurator { public void doFoo(String msg) { doWidget(msg, Config.ALWAYS); } public void doBar(String msg) { doWidget(msg, Config.NEVER); } public void doBuzz(String msg) { doWidget(msg, Config.SOMETIMES); } public void doWidget(String msg, Config cfg) { // Does a bunch of stuff and hits a database. } } I'd like to write a simple unit test that stubs the doWidget(String,Config) method (so that it doesn't

问题 I'm writing a test for a method that creates a file in a directory. Here's what my JUnit test looks like: @Before public void setUp(){ objectUnderTest = new ClassUnderTest(); //assign another directory path for testing using powermock WhiteBox.setInternalState(objectUnderTest, "dirPathField", mockDirPathObject); nameOfFile = "name.txt"; textToWrite = "some text"; } @Test public void shouldCreateAFile(){ //create file and write test objectUnderTest.createFile(nameOfFile, textToWrite); /* this
