Unable to interact with FileChooser

[aimran50]

File chooser is declared inside the controller class:

• FileChooser fileChooser = new FileChooser();

User clicks the add button which opens the file chooser. Returned files are then processed
public void add() {
List files = fileChooser.showOpenMultipleDialog(stage);
process(files);
}

After the file chooser is launched, TestFX is unable to interact with the file chooser. clickOn, doubleClickOn, press or write don't work. I am not even able to close the chooser dialog.

I need the test to select a file and return back. How can this be achieved?

Expected Behavior

Select a file and return

Actual Behavior

Does nothing

Facing the same issue.

Googling, I found this variant of FileChooser, claiming to be testable using TestFX.

I don't know yet if it's any good, or if there are better options.

I think, JavaFX uses the platforms native file chooser. Hence, the robot is not able to interact with these elements.
Other than writing an adapter class to the native file chooser, I also have no clue how to make a (most likely) native component testable.

May be this is something to be discussed also for JavaFX/OpenJFX in general.

Besides that, the FXFileChooser is currently kind of outdated and requires some more care to get it into shape. Nevertheless, its plain JavaFX inside and as such it can be tested using TestFX. But it's still on JavaFX8 and Java8.

My solution was to abstract the file choosing logic away using an interface. When testing, I set up a mock instance which will return the file I want for this test. Works perfectly fine.
