Junit dependency missing in spring boot project

I am trying to learn spring boot and have a test case that is failing. I have the below pom file in which spring-boot-starter-test dependency is included. As i understand it should pull the necessary libraries from the repository for testing including Mockito, JUnit etc. In my test case file the imports are however not getting resolved even though i see the JUnit jar under maven dependencies. Could you please guide me to fix this so that i can run my test case successfully.

Below is my test class
package tacos;
import static org.hamcrest.Matchers.containsString;

#RunWith(SpringRunner.class)
#WebMvcTest(HomeController.class)
public class HomeControllerTest {
#Autowired
private MockMvc mockMvc;
#Test
public void testHomePage() throws Exception {
mockMvc.perform(get("/"))
.andExpect(status().isOk())
.andExpect(view().name("home"))
.andExpect(content().string(containsString("Welcome...")));
}
}
the screenshot shows the imports for Junit are not working.
When i run the test i get the following error.
java.lang.SecurityException: class "org.hamcrest.Matchers"'s signer information does not match signer information of other classes in the same package

There was a JUnit dependency in the build path configuration which i removed as i understood that maven must have pulled the it already under maven dependency because of pom file, so i removed the other JUnit from build path and the one which maven pulled remains but this causes failed imports. Should i explicitly place the JUnit dependency on build path again even though the spring-boot-starter-test dependency includes it? Why are my imports not getting resolved.

java.lang.SecurityException: class "org.hamcrest.Matchers"'s signer information does not match signer information of other classes in the same package is most likely caused by mismatch between Eclipse IDE provided libraries and the libraries defined in your project.
The root cause is probably Bug 405276 - Hamcrest all 1.3 which was fixed some time ago already. Perhaps you are using an old version of Eclipse IDE and the problem will go away if you update?
hamcrest - issue #128 gives few workarounds for the problem:
Comment #5
Posted on Feb 11, 2011 by Happy Giraffe
I believe if you look at the "Order and Export" tab in the java build path property (Configure Build Path), you will find that the JUnit jar is above the hamcrest.jar. You can move hamcrest above the JUnit jar here and the problem will go away.

Recent versions of Spring Boot supports JUnit5 (jupiter) out of the box. So you shouldn't use JUnit4 (vintage), unless you really need it because of legacy code. In that case, you'll need to exclude JUnit5 in favor of including JUnit4.
Please, take a look at the imports and the absence of #RunWith(...) annotation.

Hi I had the same problem when cucumber 7 came out, and just today I was able to solve it, basically what I did was to update the versions of some other frameworks that might be affected by the cucumber version as well (on my pom.xml file). These are the frameworks that I use in the stable version:

I hope this helps to solve your problem, best regards!

Ahh, this is a tricky one. From the 'PluginFactory' stacktrace, I guess its caused by this:
You have a class which contains step bindings ("Given I login" for example).
To create that class you require specflow to Inject some class into the constructor (dependancy injection). If THAT class is in another project, but the StepAssembly (see specflow.json or app.config) or project reference is not correct this can happen.
See code example (C# unfortunatly, but the point should be clear)
[Binding]
public class Test{
public Test(ThisClassNotInAssembly getMe){
getMe.SomeFunction();
}
}
Other option is that a step requires a transform (from string to MyNotDependancy class). Where again, the class is in another project and at runtime the dependancy fails.

To find out which class was loaded (and which was not, respectively), run Java in verbose mode but limited to classloading like so:
java -verbose:class ...
From that output you should be able to decide which exact class was missing. If again you are looking at GeneratedMessageV3, try to look at the source code of that class. It may be that some static initializer is throwing an exception that simply told the JVM that this class could not be loaded successfully.

Spring boot mock CREATED POST response

Completely new to spring-boot.
I am trying to write a test for my POST method that returns a response of CREATED with the path of the resource. I am coming across all sorts of problems for something that I was assuming is very straight forward. In the code bellow is my current test class which seems to be crashing with a
ClassNotFoundException
on the first line of my method.
#RunWith(SpringRunner.class)
#WebMvcTest(AResource.class)
public class AResourceTest {
#Autowired
private MockMvc mockMvc;
#MockBean
private AResource aResourceMock;
#Test
public void testPOST() throws Exception {
Response.ResponseBuilder created = Response.created(UriBuilder.fromPath("/123").build());
when(aResourceMock.create(123)).thenReturn(created.build());
mockMvc.perform(MockMvcRequestBuilders
.request(HttpMethod.POST, "/account")
.content("{\t\"id\": \"123\"}"))
.andExpect(MockMvcResultMatchers.status().isCreated());
}
}
Any idea how to properly mock my response? Thanks

I'm not sure what you are trying to do and why you would want to mock the Response. When you are running a a test for your resources, generally wha you want to do is run integration tests. What this entails is making an actual request to the endpoint using a client library. MockMvc only works when you are using Spring MVC as the REST framework. But in your case, you are using Jersey (I assume, based on the jax-rs tag in your post.
As far as the client library, you can use the Jersey/JAX-RS Client API or you can use Spring Boot's TestRestTemplate, like they do in the official Spring Boot/Jersey sample project. For checking the created URI for the POST/Created resource, what you should be doing is checking the Location header in the response. This is was is set on the server side when you do Response.created(URI). For example, say this is your resource
#Path("customers")
public class CustomersResource {
#POST
#Consumes(MediaType.APPLICATION_JSON)
public Response createCustomer(Customer customer, #Context UriInfo uriInfo) {
int customerId = // create customer and get the resource id
UriBuilder builder = uriInfo.getAbsolutePathBuilder();
builder.path(Integer.toString(customerId));
return Response.created(builder.build()).build();
}
}
Jersey will automatically set the Location to value of the URI passed to created()
Then (if you're using the Jersey Client), then your test might look something like
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class ExampleResourceTest {
#LocalServerPort
private int port;
private Client client = ClientBuilder.newClient();
#Test
public void testCustomerLocationOnPost() {
Customer customer = new Customer("Jane", "Doe");
URI resourceUri = UriBuilder.fromUri("http://localhost")
.port(port).path("api").path("customers").build();
Response response = client.target(resourceUri).request().post(Entity.json(customer));
// test that we get the correct status code
assertThat(response.getStatus())
.isEqualTo(Response.Status.CREATED.getStatusCode());
// test that the location header is correct.
assertThat(response.getHeaderString(HttpHeaders.LOCATION))
.isEqualTo(UriBuilder.fromUri(resourceUri).path("123").build().toString());
}
}
As far as the dependencies, to use Jersey with Spring Boot you need to use the spring-boot-started-jersey dependency. Also get rid of the jersey-core dependency you have. See the linked project above for complete example.

Try adding to your pom.xml:
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-server</artifactId>
<version>2.27</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-common</artifactId>
<version>2.27</version>
<scope>provided</scope>

JUnit, JPA, Hibernate and Postgres: How to test?

I've been stuck for a while now. I have searched a lot and I can't find the easiest way to test entity classes or JPA operations against a postgres database. I've found how to using Spring, Mockito and other things, but I can't find the simplest way using pure Java.
I have the following JUnit test:
public class ModelConverterTest {
private static EntityManagerFactory emf;
private static EntityManager em;
public ModelConverterTest() {
}
#BeforeClass
public static void setUpClass() throws Exception {
emf = Persistence.createEntityManagerFactory("PU");
em = emf.createEntityManager(); // Retrieve an application managed entity manager
}
#AfterClass
public static void tearDownClass() throws Exception {
em.close();
emf.close(); //close at application end
}
#Before
public void setUp() {
...
}
#After
public void tearDown() {
}
/**
* Test of SIMModelToModel method, of class ModelConverter.
*/
#Test
public void testSIMModelToModel() {
System.out.println("SIMModelToModel");
SIMModel simModel = new PESMModel();
simModel.addState(testState);
Model expResult = null;
Model result = ModelConverter.SIMModelToModel(em, simModel);
assertTrue(expResult!=null);
// TODO review the generated test code and remove the default call to fail.
//fail("The test case is a prototype.");
}
}
and when running it, I get the following error:

What should I do to make the test run?

Quoting Trouble With Crippled Java EE 6 APIs in Maven Repository And The Solution by Adam Bien:
Instead of using
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>6.0</version>
<scope>provided</scope>
</dependency>
You should use alternative (geronimo, jboss etc.) dependencies:
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-ejb_3.1_spec</artifactId>
<version>1.0</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-jpa_2.0_spec</artifactId>
<version>1.0</version>
<scope>provided</scope>
</dependency>

Had a similar issue. i.e Even though the Hibernate JPA jar was available through transitive dependencies and javaee 6.0 dependency was provided, the JUNIT Test case was failing. I just moved the javaee dependency at the end of the dependencies definition on the pom file so that the hibernate JPA api jar appeared before the Javaee jar during classpath resolution. That seemed to do the trick and I was able to run the test case. Hope this helps.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>${hibernate.version}</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>${hibernate.version}</version>
</dependency>
javaee appears after hibernate dependency
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0</version>
<scope>provided</scope>
</dependency>

If you want to use JPA in your tests, then you will need to have a JPA provider on the classpath when you run them. You can compile against javaee-api, but you must have a real, live provider at runtime.
You mention that you're using GlassFish; that uses EclipseLink as its provider, so it would make sense for you to do the same for your tests. There's information about using EclipseLink via Maven on their wiki.

We a very similar issue: Junit tests were successfully executing during maven build, however trying to run them from Eclipse directly showed this awful "Absent Code" error. The solution is not in pom.xml-s (they must be right since your build runs, right?) but the configuration of Junit execution in eclipse. In our case, when the maven dependencies were moved on top of the project itself, the correct implementation (eclipselink 2.0.4) persistence classes were loaded. So in eclipse try to check "Run Configurations...", select the Junit configuration in question and on the "Classpath" tab, change the order of libraries in the "User Entries" section: move Maven dependencies on top.
Best regards,
Joe Public

In my case under Run Configurations/ClassPath on the the project, click Edit and check "Only include exported entries" that did the trick.
