QUESTION
I am doing unit testing, and basically want to check that the data that 2 objects hold is the same
...ANSWER
Answered 2022-Apr-08 at 07:47You could either use records (c# 9 +) or you have to override the Equals method (if you have access and you can change the objects that you're working with). Records example:
QUESTION
I want to learn how to write JUnit tests and I fail completely.
This is my test:
...ANSWER
Answered 2022-Apr-07 at 15:33You initialize your mocks twice - first by @RunWith(MockitoJUnitRunner.class)
and then with MockitoAnnotations.openMocks(this);
This means that when you enter your setUp method:
- customerRepository points to R1
- customerService.customerRepository points to R1
And after this method
- customerRepository points to R2
- customerService.customerRepository points to R1
Which means that your service was not re-initialized
Use a debugger to confirm this observation.
@InjectMocks javadoc says:
MockitoAnnotations.openMocks(this) method has to be called to initialize annotated objects. In above example, openMocks() is called in @Before (JUnit4) method of test's base class. For JUnit3 openMocks() can go to setup() method of a base class. Instead you can also put openMocks() in your JUnit runner (@RunWith) or use the built-in MockitoJUnitRunner.
QUESTION
So I want to create an assertion class like how AssertJ works. I'm having trouble getting started.
...ANSWER
Answered 2022-Mar-22 at 18:21I don't think that's how JUnit works (but AssertJ does).
But yes, you create an instance with a static method and hold the value, and then perform an assertion against that value.
New invocations to the static method (also know as factory method) will create different instances.
Here's a very simple example:
QUESTION
I store JSON in my database and want to include this JSON in an API response as-is, without de-serializing before serializing the data. The data itself resides in a wrapper object. When serializing this wrapper, it appears the JSON from my database isn't pretty-printed alongside the rest of the data, giving really weird-looking responses.
I have written some example code to outline my issue:

Can you try to save the properties without the spaces.
Like this:
logging.file.name=application.logs

My requirement is to show all the failures after Junit test run.
I tried two things:
Assertions.assertEquals --> This stops the execution after first failure, and in test report I see only first failure.

QUESTION
I'm currently working at a Java application that I'm testing using JUnit Jupiter. I am starting to work at the GUI and I was wondering if it was possible to use AssertJ-Swing with JUnit 5. As a matter of fact I have found an open issue on AssertJ-Swing GitHub page.
The suggestion they give is to define a GUITestExtension like so:

Answered 2022-Jan-08 at 11:23Assuming that the GUITestExtension
mentioned in the issue is defined in your codebase, it could be registered in the following way:
QUESTION
I'm using the Maven Integration Testing Framework plugin to test one goal of a custom-developed plugin. As far as the tests go, everything works well. However, there is one unexpected and undesired technicality that I have noticed:
The local repositories created for individual test cases in target/maven-it/.../test-case/.m2/repository
are always populated remotely - from the Maven Central Repository. If I run mvn clean integration-test
without being connected to the Internet, the dependency resolution results in an error after a failed connection attempt. I would expect it, however, to look for the dependencies in the "standard" cache located in USER/.m2/repository
first, where the dependencies were already present in my experiment.
It's interesting that even after adding the --offline
option to mvn clean integration-test
, online dependency resolution is still attempted.
My main question is - should this be happening? Is this the expected behavior when using the Maven Integration Testing Framework? Or do you think there might be something wrong with the way I'm using it?
Related dependencies from the pom.xml
of the tested custom-developed plugin:
ANSWER
Answered 2022-Jan-13 at 20:24If the dependencies would be consumed from the users local cache $HOME/.m2/repository
it could happen that parts which are already in the local cache influence the integration test. That's one of the the reasons each integration tests is completely separated from each other.
Furthermore it makes it possible to parallelise the integration tests in an easier way.
Furthermore you can configure your own settings.xml
to consume any dependencies from an repository instead directly from central this would also mean that the integration test would consume their dependencies from that
repo.
Apart from that the usage of the users local cache would make it impossible (or at least much more complicated) to create a local cache with predefined state (which means already existing artifacts) to test particular scenarios.
