Examples
Simple test
The first step is to create your container for test purpose.
| Code Block |
|---|
public class StupidTestContainer extends AbstractContainer
{
/**
* Init component bindings
*/
public void fillContainer(MutablePicoContainer pico)
{
pico.addComponent(System.getProperties()
.addComponent(Mockito.mock(List.class))
}
}
|
Here we have 2 components, a Properties and a mock list.
To use this container in your test, use the customRunner PicoRunner and configure the container with @Container.
You will be able to ask any components of the container in the test constructor. Moreover, an instance of the test is created for each test methods. So you don't have to worry about cleaning the container.
| Code Block |
|---|
@RunWith(PicoRunner.class)
@Container(StupidTestContainer.class)
public class StupidTest
{
private List mockedList;
public StupidTest(Properties property, List list)
{
this.mockedList = list;
}
@Test
public void testList() throws Exception
{
//using mock list
mockedList.add("one");
mockedList.clear();
//verification
verify(mockedList).add("one");
verify(mockedList).clear();
}
}

Panel display tests
The following examples are taken from the izpack-test-panel module which contains small and fast GUI tests
| Code Block |
|---|
@RunWith(PicoRunner.class)
@Container(TestPanelContainer.class)
public class TestPanelDisplay
{
private GUIInstallData guiInstallData;
private FrameFixture frameFixture;
private ResourceManager resourceManager;
private InstallerFrame installerFrame;
private UninstallDataWriter uninstallDataWriter;
public TestPanelDisplay(GUIInstallData guiInstallData, InstallerFrame installerFrame, ResourceManager resourceManager, FrameFixture frameFixture, BindeableContainer container, UninstallDataWriter uninstallDataWriter)
{
this.guiInstallData = guiInstallData;
this.installerFrame = installerFrame;
this.resourceManager = resourceManager;
this.frameFixture = frameFixture;
this.uninstallDataWriter = uninstallDataWriter;
}
|
The majority of instantiation logic is in the container. We have ready to use components and mocks for your test.
| Code Block |
|---|
@Test
public void htmlInfoPanelShouldDisplayText() throws Exception
{
addPanelAndShow("com.izforge.izpack.panels.htmlinfo.HTMLInfoPanel");
String textArea = frameFixture.textBox(GuiId.HTML_INFO_PANEL_TEXT.id).text();
assertThat(textArea, StringContains.containsString("This is a test"));
}
@Test
public void licencePanelShouldDisplayText() throws Exception
{
addPanelAndShow("com.izforge.izpack.panels.licence.LicencePanel");
String textArea = frameFixture.textBox(GuiId.LICENCE_TEXT_AREA.id).text();
assertThat(textArea, StringContains.containsString("This is a licenSe panel"));
}
