            Java Mocking a private final field or response form RestHighLevelClient
            Asked 2022-Mar-31 at 06:09

            I am trying to write a testcase for the below method and I need to mock the response obtained from the elastic search db.



            Answered 2022-Mar-31 at 06:09

            There's a workaround I can think of, you can mock the static method of object creation of RestHighLevelClient using mock static(checkout) https://mvnrepository.com/artifact/org.mockito/mockito-inline

            I am using Gradle testImplementation 'org.mockito:mockito-inline:3.4.6' This worked for me, let me know

            Unable to mock System class static method using PowerMockito
            Asked 2022-Mar-27 at 05:42

            Even though I have read the manual and gone through multiple answers for Powermock, could not mock a static method for my use case.




            Answered 2022-Mar-27 at 01:05

            java.net.InetAddress is a system class. The caller of the system class should be defined in @PrepareForTest({ClassThatCallsTheSystemClass.class}).
            See documentation.

            The way to go about mocking system classes are a bit different than usual though. Normally you would prepare the class that contains the static methods (let's call it X) you like to mock but because it's impossible for PowerMock to prepare a system class for testing so another approach has to be taken. So instead of preparing X you prepare the class that calls the static methods in X!

            Please note @InjectMocks annotation does not inject static mocks, it can be removed.

            Why does ExceptionInInitializerError occur when invoking HtmlCompat in an Android unit test using Robolectric?
            Asked 2022-Mar-21 at 13:56

            I am attempting to unit test a method that is part of my use case layer of an Android app. The method receives an XML RSS feed and returns it to the view model as GSON-parsed objects. The testing class is annotated with @RunWith(RobolectricTestRunner::class).

            The test fails because a java.lang.ExceptionInInitializerError (among others) is thrown by .fromHtml() within this method of the use case class:

            NotAMockException exception when trying to verify a static method with Powermockito

            They probably just changed the naming scheme for the plugin. Looks like you have one that is about one and a half years out of date.

            Set value for private final static inlined variable using Mockito
            Asked 2021-Dec-23 at 12:40

            I'm trying to test a method which calls another method which makes use of a private final static variable initialized inline. I'm then trying to change the value for the variable when the tests run. I've been trying things such as spring reflection or adding a setter for that specific field but maybe I should use something as powermock, which I never used before. I'm on my own trying to implement this with no one to ask so if I could have some guidance on what is the best way to proceed, please.


            Based on some feedback I got here, mocking the private final variable may not be what I should do for my my tests. I've opened a different issue here Mock return value for cookie.getValue() using Mockito



            Answered 2021-Dec-23 at 07:10

            Not sure if even Powermock will be able to help.

            The recommended way is to not use inline constants which need to be changed while testing.

            • If you want to change this, you need to introduce an interface in between which supplies constants. Use one implementation of it for the actual source and one for tests. Switch the implementation while testing.

            If you do not want to change this, you could try the below approach with reflection

            • Make the field accessible.
            • Remove the final modifier
            • edit the field value

            I got this suggestion from this discussion

            Asked 2021-Dec-17 at 09:54

            I am trying to write unit tests for a RecyclerView.ViewHolder class which uses ViewBinding but I am facing issues to inflate my ViewBinding in my test class, having this error when running my test : Binary XML file line #38: Binary XML file line #38: Error inflating class Caused by: java.lang.UnsupportedOperationException: Failed to resolve attribute at index 5: TypedValue{t=0x2/d=0x7f04015d a=2}

            I could not find code examples of ViewBinding inflate in test classes, is that possible ? I found this StackOverflow thread but it uses PowerMock to mock a ViewBinding class. I'm using mockK in my project and I think using a real ViewBinding instance would be better in my case.

            My ViewHolder looks like this :



            Answered 2021-Dec-15 at 13:55

            I was able to get this working (using Mockito, but it should be applicable to MockK too) by looking in the generated binding class to see what methods I needed to mock to get it to inflate and return mocked views properly. These files are in app/build/generated/data_binding_base_class_source_out/debug/out/your/package/databinding for a standard build

            Here is an example of a generated data binding class with three views in a ConstraintLayout.

            Answered 2021-Nov-09 at 08:57

            There's little value in writing a unit test for your Spring Boot entry-point class ObsDocumentApplication as you end up with almost an exact copy of your implementation.

            Such tests can only verify that your mocking setup matches your implementation. Any change to your implementation will most probably fail the unit test as the stubbing setup needs to be adjusted.

            A better approach is to write an integration test that makes sure your Spring ApplicationContext can launch (which will implicitly verify your ObsDocumentApplication).

            You can use the @SpringBootTest annotation for this purpose.
