#RunWith(DataProviderRunner.class)
#RunWith(SpringJUnit4ClassRunner.class)
public class DatabaseModelTest {
// some tests
}
or
#RunWith(Parameterized.class)
#RunWith(SpringJUnit4ClassRunner.class)
public class DatabaseModelTest {
// some tests
}
We can not use two runner property in one test case class...!! so that
I want to run test case with Multiple data how i pass multiple parameter in Rest web service to execute test case ??
Any solution for extend class for DataProviderRunner or parameterized ??
Thanks

You could use Spring's JUnit rules instead of the SpringJUnit4ClassRunner. This works at least with the Parameterized runner. I don't know whether it works with the DataProviderRunner, too.
You need at least version 4.2.0 of the Spring framework and spring-test.
#RunWith(Parameterized.class)
public class DatabaseModelTest {
#ClassRule
public static final SpringClassRule SCR = new SpringClassRule();
#Rule
public final SpringMethodRule springMethodRule = new SpringMethodRule();
...
}
I tested the solution of #Stefan and works also well for #RunWith(DataProviderRunner.class)
I found a second solution in DataProvider for Spring Integration Testing, they wrote a class DataProviderRunnerWithSpring and set the test class like:
#RunWith(DataProviderRunnerWithSpring.class)
public class TestClass{
...
}

Using Junit version 5.9.2 I am trying to programmatically add parameter resolvers extension for a test class constructor with a #TestTemplate annotation.
I am trying to add the extensions programmatically using #RegisterExtension.
Example:
public class MyTestClass {
#RegisterExtension
static final TestDependencyResolver resolverExt = new TestDependencyResolver(/*...*/);
private final TestDependency dependency;
public MyTestClass(TestDependency dependency) {
this.dependency = dependency;
}
#TestTemplate
#ExtendWith(SomeContextProvider.class)
void test() {
//...
}
}
I have tried:
making resolverExt field non static
Movine #ExtendWith(SomeContextProvider.class) to class level
And other possible combinations of 1 and 2.
In all cases the ctor parameter dependency is not injected and TestDependencyResolver::resolveParameter is not called, which to my understanding means the object was created without/before registering TestDependencyResolver, please correct me if I am wrong.
Is what I am trying to achieve possible? thanks.
Turns out the issue was not Junit5 but TestTemplateInvocationContextProvider I was using.
I used PactVerificationInvocationContextProvider which seems to have a bug and throws NullPointerException when resolving Ctor params, I have opened an issue for it if you want more details.
I have implemented a generic TestBase.java and many test case class extends this base.
#BeforeClass method is to prepare some specific data for corresponding test case class.
My question is, is it possible to get the invoking test case classname in TestBase #BeforeClass method so that I can use the classname to get correct data prepared?
I don't want to implement the #BeforeClass in separate test case class, as the steps are totally the same, the only difference is the data name which can be generated by test case classname.
For example:
My project is to test query function of our product.
Test case classes like GenericQueryTest.java, BooleanQueryTest.java etc.
Each test case class need to index prepared data before run test and cleanup the environment after all tests in the testcase class finish.
I implemented a TestBase.java like following.
public class TestBase {
#BeforeClass
public static void setUpBeforeClass() throws Exception {
I want to get invoked test case class name here. if I get the name(eg. classname= "GenericQueryTest ")
File testDataFile = new File("C:/users/" + classname +".csv";
then read the "C:/users/GenericQueryTest.csv "to prepare data in env
}
public class GenericQueryTest extends TestBase{
I donot need to implement #BeforeClass
#Test
.....
#Test
...
}
I figured out how to resolve the problem. Just implement customized runner. And you can get Class from the runner.
I'm using Springboot2, Spring5 and reactive-webflux in my Java microservices.
I have a service class which I want to test using webtestclient:-
#Service("authenticationProvider")
public class CommonAuthenticationProvider implements AuthenticationProvider {
#Override
public AccessToken getUserAccessToken(Tuple2<String, WebClient> serviceConnectionDetails, MultiValueMap<String, String> queryParams) {
return serviceConnectionDetails._2
.post()
.uri(builder -> builder
.path(serviceConnectionDetails._1)
.queryParams(queryParams)
.build())
.accept(MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML)
.retrieve()
.bodyToMono(AccessToken.class)
.block();
}
}
Here serviceConnectionDetails._2 is a webclient instance. I want to write a JUnit test to mock this webclient and test the method getUserAccessToken(). Please assist as I had tried many things like mockmvc, mockRestServiceServer but nothing worked. Later I came to know that, I cannot user mockRestServiceServer since it used to mock RestTemplate and not WebClient. I can test controller class methods using webtestclient but not this at service class
This should be supported in a future Spring Framework version with MockRestServiceServer; see SPR-15286.
For now, the only solution is to use a separate library for that, such as okhttp's MockWebServer.
I am having a hard time getting this one piece of mocking figured out for my unit tests. The classes in question are all part of legacy code that I don't really have the option of changing right now (I am hoping to be able to do some refactoring in the future, but need tests now).
Here are the two classes that I am dealing with, and the specific part I am having trouble with. Class A declares an object using new and then class B uses the object. I am trying to mock the object but I keep getting the real version of it instead of the mocked version.
public class B extends A(){
...
int x = problemObj.doMethod();
}
public class A(){
...
ProblemObj problemObj = new ProblemObj();
}
Here is my test class.
#RunWith(PowerMockRunner.class)
#PrepareForTest({A.class, B.class})
public class ATest(){
private ProblemObj problemObjMock;
#Before
public void setUp(){
problemObj = PowerMockito.Mock(ProblemObj.class);
}
#Test
public void test(){
PowerMockito.whenNew(ProblemObj.class).withNoArguments().thenReturn(problemObj);
...//rest of test below here
}
}
I have done other whenNew mocking in tests and set it up the same way as this. But for some reason this object being in the superclass is really throwing me off.
Versions used are Junit:4.11, Mockito:1.9.5, Powermock: 1.6.6
In JUnit3, one would could name a test suite like this:
public static Test suite() {
TestSuite suite = new TestSuite("Some test collection");
suite.addTestSuite(TestX.class);
return suite;
}
Is there an equivalent way to do this in JUnit4?
Thanks.
EDIT
Thank you, I actually managed to get it working. My question was if there is a JUnit4 equivalent way of specifying the name/description of a test suite, like in JUnit3 with "Some test collection".
Some background:
I'm converting junit tests in legacy code to the version 4, and I don't want to lose any information if possible. I apologize, I should really have been more specific in the original question.
You can do this with the Suite runner #RunWith(Suite.class):
#RunWith(Suite.class)
#SuiteClasses({Test1.class, Test2.class, TestX.class})
public class MySuite {}
Where Test1, Test2, TestX contain your tests
ref. RunWith, Suite
update:
WRT changing the actual description of your suite, I don't think there's a way to do it out-of-the-box (if there is I haven't seen it yet). What you can do, is to define your own runner with a custom description [update2]:
#RunWith(DescribedSuiteRunner.class)
#SuiteClasses({Test1.class, Test2.class, TestX.class})
#SuiteDescription("Some test collection")
public class MySuite {}
public class DescribedSuiteRunner extends Suite {
// forward to Suite
public DescribedSuiteRunner(Class<?> klass, RunnerBuilder builder)
throws InitializationError {
super(klass, builder);
}
#Override
protected String getName() {
return getTestClass()
.getJavaClass()
.getAnnotation(SuiteDescription.class)
.value();
}
}
#Retention(RetentionPolicy.RUNTIME)
#Target(ElementType.TYPE)
public #interface SuiteDescription {
String value();
}
The default implementation of getName just returns the class being tested's name
Yes, In JUnit 3.x, the JUnit methods had to be specifically named. They needed to begin with the word test in order for JUnit to run that as a test case. Now you can just use the #Test annotation:
#Test
public void thisIsMyTest() {
// test goes here
}
Also in JUnit4 you can state if you want some tests to run before or after all the tests in this class are invoked:
#Before
public void init() throws Exception {
System.out.println("Initializing...");
}
#After
public void finish() throws Exception {
System.out.println("Finishing...");
}
Further comparisons between JUnit3 and JUnit4 here and here.
Edit: after blgt's comment, I see I might have misunderstood your intent.
You are probably looking for #RunWith(Suite.class) - When a class is annotated with #RunWith, JUnit will invoke the class in which is annotated so as to run the tests, instead of using the runner built into JUnit. Full example of usage is here, tl;dr below:
#RunWith(Suite.class)
#SuiteClasses({ FirstTest.class, SecondTest.class })
public class AllTests {
...
}
