What you try to achieve will not work. The problem is that powermock must rewrite the client class’s code to intercept the static invocation and it can’t do this after the class is loaded. Thus it can only prepare a class for test before it is loaded. Let’s assume you want to mock the System.currentTimeMillis … Read more
You need to use mockito-inline version 3.4.0 or higher and remove mockito-core from your dependencies (mockito-inline depends on mockito-core so it will be retrieved automatically). That way, you will be using mockito static mocking correctly, but it wouldn’t solve the exception that you posted. To fix it, you need to remove all dependencies of powermock … Read more
I had a similar issue and it was suggested to me to create a Resources.java class that Produced an Entity Manager. @Stateful public class Resources implements Serializable { @PersistenceContext (type = PersistenceContextType.TRANSACTION) private EntityManager entityManager; @Produces public EntityManager getEntityManager() { return entityManager; } } I’m still not exactly sure why this solution worked for me… … Read more
After one year of no releases, things are really moving in PowerMock. PowerMock 2.0.0-RC1 was released. And with PowerMockito 2.0.0-RC1 + @PowerMockIgnore({“com.sun.org.apache.xerces.*”, “javax.xml.*”, “org.xml.*”, “org.w3c.*”}) The tests work under Java 11.
That annotation tells PowerMock(ito) that the listed classes will need to be manipulated on the byte code level. You need to “prepare for test” all these classes X of which you want to mock a static method (on X) gain control over calls to new() used in another class X gain control over private methods … Read more
It is very likely that the Runnable hasn’t been executed yet by the asyncTaskExecutor when you verify the invocation, resulting in a verification error in your unit test. The best way to fix this is to join on the generated thread and wait for execution before verifying the invocations. If you cannot get the instance … Read more
I had a test dependency on a third-party jar which used powermock. In order to resolve this error, I had to add: @PowerMockIgnore(“jdk.internal.reflect.*”) To the class that is tested with powermock
From Mockito 3.4.0 (2020-07-10), it is possible to mock static methods out of the box even in JUnit 5, without any extension. In the documentation, you can find an example: 48. Mocking static methods (since 3.4.0) Important note: You need to use inline mock maker. So the dependency to use is not the core one: <dependency> … Read more
Powermock 1.6.3 uses javassist 3.15.2-GA which does not support certain types. Using 3.18.2-GA javassist worked for me. You may want to override dependency in your project. <dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.18.2-GA</version> </dependency> You may face another problem for which the solution lies here Mockito + PowerMock LinkageError while mocking system class Hope this helps.
I think MockK can help you. It supports mocking extension functions too. You can use it to mock object-wide extensions: data class Obj(val value: Int) class Ext { fun Obj.extensionFunc() = value + 5 } with(mockk<Ext>()) { every { Obj(5).extensionFunc() } returns 11 assertEquals(11, Obj(5).extensionFunc()) verify { Obj(5).extensionFunc() } } If you extension is a … Read more
