QUESTION
I am currently learning JFoenix library. There is a nice demo and instructions how to run it.
JFoenix uses Gradle, but I need to use Maven, so I've decided to recreate the demo project using Maven for further testing.
The problem appeared when I tried to run my newly created project. It turned out that some classes (e.g. de.jensd.fx.glyphs.GlyphIcon
) were not found. I found out that de.jensd:fontawesomefx-fontawesome:4.7.0-5
depends on de.jensd:fontawesomefx-commons:8.15
in runtime. So I decided to add it as compile dependency and the demo ran correctly. But build.gradle of the demo specifies only de.jensd:fontawesomefx-fontawesome:4.7.0-5
.
Do Maven and Gradle handle dependencies in a different way? Or is it a specific case?
Here is my pom.xml

QUESTION
I have to write a java project for a course and our professor requires us to use CMake as a build tool. In my Entry Point (main class) I want to use a class located in another package. While trying to compile it I get the following error message (attached below).
Using this wildcard import in Foo.java
...ANSWER
Answered 2018-Mar-25 at 21:32Seems quite logical to get this error. CMake as the other make utilities depend heavily on the order in which the classes get compiled.
From the makefile you've attached it's obvious that the make's entry point is 'xxx.gui.Foo' package problem is though that Foo.java has a dependency to Bar.java which at this point has not been compiled yet.
If you switch the order you could get this to work without any issue, that is Bar.java getting built before Foo.java.
All in all it's a good idea if you ever need to use make files to keep all the utility classes and in general all the classes with as little dependencies to other packages/classes on the top of you make file in order to minimize such problems.
Now, answering as to why you don't get this problem with Maven or javac, in case of the former it's a build tool thus it has a way no resolving all those on it's own. In case of the latter, I suppose that you already had both of the classes compiled hence why it's worked.
I hope the above solves your question.
QUESTION
How do we properly write unit/integration tests for the JavaFX Controller logic?
Assuming the Controller class I'm testing is named LoadController
, and it's unit test class is LoadControllerTest
, my confusion stems from:
If the
LoadControllerTest
class instantiates a newLoadController
object viaLoadController loadController = new LoadController();
I can then inject values into the controller via (many) setters. This seems the only way short of using reflection (legacy code). If I don't inject the values into the FXML controls then the controls obviously aren't initialized yet, returning null.If I instead use
FXMLLoader
'sloader.getController()
method to retrieve theloadController
it will properly initialize the FXML controls but the controller'sinitialize()
is thus invoked which results in a very slow run, and since there's no way to inject the mocked dependencies, it's more of an integration test poorly written.
I'm using the former approach right now, but is there a better way?
TestFX
The answer here involves TestFX which has @Tests
based around the main app's start
method not the Controller class. It shows a method of testing the controller with
ANSWER
Answered 2017-Jan-21 at 06:41You can use a test framework like Mockito
to inject your dependencies in the controller. Thereby you can forgo probably most of the setters, at least the ones that are only present to facilitate testing.
Going with the example code you provided I adjusted the class under test (define an inner class for the FileSorter
):

Install DataFX
You can use DataFX like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the DataFX component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
