Unable to find component using matcher | Fail on Ubuntu #254
Comments
|
I am having similar issues on Linux! On both matching standard components (e. g. JButton) and private component (e. g. extending JPanel) I am encountering flickering tests, meaning sometimes the error occurs and sometimes it doesn't. I am still investigating, but I would also be interested what others have to say. |

protected JLabel label = null;
protected JButton btn = null;
protected JPanel panel = new JPanel();
public WFrame(String title) {
this.setTitle(title);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setSize(300,400);
this.setPane(getContentPane());
this.setVisible(true);
}
private void setPane(Container c) {
c.add(panel.add(getLabel()),BorderLayout.NORTH);
c.add(panel.add(getButton()),BorderLayout.CENTER);
}
protected JLabel getLabel() {
if(this.label == null) {
this.label = new JLabel("Test");
this.label.setText("Test");
}
return this.label
}my suite tests package test;

mockWindow = new FrameFixture(frame);
mockWindow.show();
}
@After
public void after() {
mockWindow.cleanUp();
}
// healthy
@Test
public void LabelBindDataCheckWithNoTarget() {
mockWindow.label().text().equals("Test");
