I am trying to test my web application using JUnit. I saw that there is cdi-unit which seems pretty nice or Arquillian with JBoss (I am on Seam3, JBoss 7.1.3) but I can't make it work.
As soon as I try to inject a bean (and I need to inject multiple beans for my tests), it isn't working. I get "unsatisfied injection for type[...] with qualifiers [#default] at injection point".
Especially for the EntityManager which I need to inject. Is there some easy plugin I can add to my pom file in order to get this working ?
Thanks !
You should have a look at the DeltaSpike Test Control module. This will start an embedded CDI container in your test. It is really simple to set up.
Have a look at the module documentation here:

I'm building a suite of REST micro-services using .Net Core 3.0 Preview 6. All these services will have the same start up logic. So, I'm trying to place all the code in a .Net Standard library.
The goal is to have the IHostBuilder:CreateHostBuilder method, as well as the Startup:Configure and Startup:ConfigureServices class and methods in the library. The library will also contain error handling logic, customized http response messages, etc.
However, I can't seem to find the correct package that contains the ConfigureWebHostDefaults method. I tried adding the Microsoft.AspNetCore package 2.2.0, but that didn't resolve the issue.
I added the Microsoft.Extensions.Hosting (3.0.0-preview-6) package, that also doesn't resolve the issue.
Is what I'm attempting even possible?
Thanks

I resolved it, not the best way, but it works. I decided to make the library targeted specifically for .NET Core 3.0. So, I changed the targetframework in the project file. That change automatically resolved my other issue.
Import the Microsoft.AspNetCore package, and use WebHost.CreateDefaultBuilder() instead. According to the code it is built from, both CreateDefaultBuilder() and ConfigureWebHostDefaults() call the same internal method: ConfigureWebDefaults().
The only downside of this is that the returned host will be an IWebHost instead of an IHost.
I'm trying to write a test that needs both Robolectric 2.2 and PowerMock, as the code under test depends on some Android libraries and third party libraries with final classes that I need to mock.
Given that I'm forced to use the Robolectric test runner through:
#RunWith(RobolectricTestRunner.class)
...I cannot use the PowerMock test runner, so I'm trying to go with the PowerMock java agent alternative, without luck so far.
I have setup everything according to this guide but I'm facing a collision problem between classes required by the javaagent library and by robolectric through its dependency with asm-1.4. Both depend on
org.objectweb.asm.ClassVisitor
, but javaagent-1.5.1 ships with its own version where ClassVisitor is an interface while asm-1.4 version for the same namespace is an abstract class, with the corresponding error at runtime:
java.lang.IncompatibleClassChangeError: class org.objectweb.asm.tree.ClassNode has interface org.objectweb.asm.ClassVisitor as super class
I have even tried to modify the javaagent library jar to entirely remove the org.objectew.asm classes in there, but that doesn't work as ClassNotFoundException happens afterwards due to some other classes needed in the org.objectweb.asm package that only ship in the javaagent library jar, and not in the asm one.
Any ideas? According to examples out there the agent seems to work fine with, at least, the Spring test runner.
I had the same problem and while I didn't solve this problem as such, I wanted to share my approach, which removes the need for PowerMock (which is always a good thing in my view): I wanted to mock a call to
Fragment fooFragment = new FooFragment();
So what I did was addanother level of indirection. I created a FragmentProvider class:
public FragmentFactory fragmentFactory = new FragmentFactory();
[...]
Fragment fooFragment = fragmentFactory.getFooFragment();
After i did this, I could just mock out the factory with standard Mockito, like this:
FragmentFactory mockFactory = mock(FragmentFactory.class);
activity.fragmentFactory = mockFactory;
when(mockFactory.getFooFragment()).thenReturn(mockFooFragment);
I do the following:
From the Package Explorer I select "New, Other, JUnit Test Case"
I write this code:
package dk.sample;
import org.junit.*;
import static org.junit.Assert.*;
public class TestCase {
#Test
public void alwaysTrue(){
assertTrue( true );
}
}
I then select "Run As, JUnit test"
Get this error: "Class not found dk.sample.TestCase
java.lang.ClassNotFoundException: ...."
What do I miss? Have tried with different Run Configurations - but it seems like I miss a classpath somewhere? But to what and where?
To make JUnit work within Domino Designer you need to perform few additional steps:
set up source control for your application
adjust the on-disk project to be recognized as Java application
run JUnit tests within your on-disk project
Please note that java agents have to be tested in a different way..
You can find more detailed explanation about enabling JUnit for both XPages and Agents in the following blog post: Unit Tests for Lotus Domino Applications
Here's also a great how-to on this topic.
Coundn't get JUnit to work inside the Domino Designer. Instead of running the tests from DDE, I now run the tests from a XPages. This works like a dream. Made my own 'JUnit runner' class - that is, I just call the JUnit runners but handles the result my self in order to display it as html on the XPage.

I have very simple scenario where class A registers instances for types.
A.register(T1.class, new H1());
A.register(T2.class, new H2());
this is fairly simple configuration when done by hand but guice injection doesn't work when I create instances outside the guice framework.
I try to figure out how to create and configure A with all instance with custom annotation using guice.
I have found something like this Scan the classpath for classes with custom annotation but it is not using guice.
thanks
so I guess code.google.com/p/google-guice/wiki/Multibindings is the only option so far that works, but it is not as nice as I would expect since you need to connect everything by hand.
So for my normal Android project, I have the following in AndroidManifest.xml:
<application android:name=".utilities.App" ...>
....
</application>
And then I have my App class:
public class App extends Application {
....
}
And then I have an Android JUnit Test project associated with the Android project. Everything is all fine and dandy and I can write JUnit tests. However, I'm trying to run code coverage with my JUnit tests and I'm getting bloated results. The reason is because my App class gets called and initialized as if my application were actually started. I do not want my custom App class to execute when I run the JUnit tests or code coverage. Any setup I would need for the JUnit tests will go in the appropriate JUnit setup() method. Is there any way I can prevent it from executing my custom App class or a way that any classes/methods/lines that are executed due to the creation of my App class aren't counted towards the code coverage?
A temporary solution that I've found will work unless someone has any better ideas.
Go into the main Android project's AndroidManifest.xml.
Change the android:name attribute from ".utilities.App" to "android.app.Application"
Run the code coverage utility/JUnit tests
Change the android:name attribute back from "android.app.Application" to ".utilities.App"
Re-deploy the app onto the device (so that it uses the right Application class when it runs external to the code coverage/JUnit tests)
I'm sure the real solution is to automate this process, but I'm too lazy to do so, and it just feels hackish and wrong. But at least it's a workaround unless someone has any ideas.
