I am struggling with this problem a bit, and I think that I have nothing fundamental in Robolectric. Usually, some Google searches may help me sort out this type of problem, but I don’t find anything useful between this and viewing the example code.
I try to imitate a click on a list item and verify that the action is triggered after the click. I keep returning to the fact that the current activity I'm testing is the result of activity. I tried to remove the entire list item by clicking on the code and checking the resulting activity, and this came back as the InstallationListActivity check that I am testing. So I came to the conclusion that the list view item is not clicked, and I just don't know why. The system logs that I installed in the test code below are the values that I expect from them. The list consists of 13 elements, and getChildAt (0) returns the title. I think getting the first element (getChildAt (1)) and calling the performClick function on it or its child text view would trigger my expected activity, but that doesn't seem to be the case. Anyway,here is the robolectric / testing code I'm using:
@Before
public void setUp() {
mAppLaunch = new ApplicationLaunchActivity();
mAppLaunch.onCreate(null);
mActivity = new InstallationListActivity();
mActivity.onCreate(null);
}
@Test
public void shouldHaveNonEmptyInstallationList() throws Exception {
assert(mActivity.installationListCount() > 0);
}
@Test
public void shouldHaveSameNumberOfElements() throws Exception {
ListView installationListView = (ListView) mActivity.getListView();
ShadowListView shadowListView = shadowOf(installationListView);
assert(shadowListView.getChildCount() == mActivity.installationListCount());
}
@Test
public void pressingTheFirstItemInTheListShouldLaunchVenueListActivity() {
ListView installationListView = (ListView) mActivity.findViewById(android.R.id.list);
System.out.println("qty: " + installationListView.getChildCount());
System.out.println("class: " + installationListView.getChildAt(0).getClass());
System.out.println("class: " + installationListView.getChildAt(1).getClass());
System.out.println("class: " + installationListView.getChildAt(2).getClass());
System.out.println("class: " + installationListView.getChildAt(3).getClass());
System.out.println("class: " + installationListView.getChildAt(4).getClass());
LinearLayout firstItemLayout = (LinearLayout) installationListView.getChildAt(1);
TextView firstItem = (TextView) firstItemLayout.getChildAt(0);
ShadowTextView shadowFirstItem = shadowOf(firstItem);
ShadowLinearLayout shadowLayout = (ShadowLinearLayout) shadowOf(firstItemLayout);
shadowLayout.performClick();
shadowFirstItem.performClick();
clickOn(firstItem);
clickOn(firstItemLayout);
System.out.println("class: " + firstItemLayout.getChildAt(0).getClass());
System.out.println("Layout shadow" + shadowOf(firstItemLayout).getClass());
System.out.println("First Item Text: " + shadowFirstItem.getText());
ShadowActivity shadowActivity = shadowOf(mActivity);
Intent startedIntent = shadowActivity.getNextStartedActivity();
assertNotNull(startedIntent);
ShadowIntent shadowIntent = shadowOf(startedIntent);
assertThat(shadowIntent.getComponent().getClassName(), equalTo(VenueListActivity.class.getName()));
}
}
