Example 6 with Matcher

use of org.hamcrest.Matcher in project material-components-android by material-components.

the class NavigationViewTest method verifyCheckedAppearance.

private void verifyCheckedAppearance(@IdRes int checkedItemId, @ColorInt int uncheckedItemForeground, @ColorInt int checkedItemForeground, @ColorInt int uncheckedItemBackground, @ColorInt int checkedItemBackground) {
    for (int i = 0; i < MENU_CONTENT_ITEM_IDS.length; i++) {

        @ColorInt final int expectedItemBackground = expectedToBeChecked ? checkedItemBackground : uncheckedItemBackground;
        // For the background fill check we need to select a view that has its background
        // set by the current implementation (see disclaimer in testBackground)
        Matcher menuItemMatcher = allOf(hasDescendant(withText(mMenuStringContent.get(MENU_CONTENT_ITEM_IDS[i]))), isChildOfA(isAssignableFrom(RecyclerView.class)), isDescendantOfA(withId(R.id.start_drawer)));

Example 7 with Matcher

use of org.hamcrest.Matcher in project material-components-android by material-components.

the class NavigationViewTest method testActionLayout.

@Test
public void testActionLayout() {
    // Open our drawer
    onView(withId(R.id.drawer_layout)).perform(openDrawer(GravityCompat.START));
    // There are four conditions to "find" the menu item with action layout (switch):
    // 1. Is in the NavigationView
    // 2. Is direct child of a class that extends RecyclerView
    // 3. Has a child with "people" text
    // 4. Has fully displayed child that extends SwitchCompat
    // Note that condition 2 makes a certain assumption about the internal implementation
    // details of the NavigationMenu, while conditions 3 and 4 aim to be as generic as
    // possible and to not rely on the internal details of the current layout implementation
    // of an individual menu item in NavigationMenu.
    Matcher menuItemMatcher = allOf(isDescendantOfA(withId(R.id.start_drawer)), isChildOfA(isAssignableFrom(RecyclerView.class)), hasDescendant(withText(mMenuStringContent.get(R.id.destination_people))), hasDescendant(allOf(isAssignableFrom(SwitchCompat.class), isCompletelyDisplayed())));
    // While we don't need to perform any action on our row, the invocation of perform()
    // makes our matcher actually run. If for some reason NavigationView fails to inflate and
    // display our SwitchCompat action layout, the next line will fail in the matcher pass.
    onView(menuItemMatcher).perform(click());
    // Check that the full custom view is displayed without title and icon.
    final Resources res = activityTestRule.getActivity().getResources();
    Matcher customItemMatcher = allOf(isDescendantOfA(withId(R.id.start_drawer)), isChildOfA(isAssignableFrom(RecyclerView.class)), hasDescendant(withText(res.getString(R.string.navigate_custom))), hasDescendant(allOf(isAssignableFrom(TextView.class), withEffectiveVisibility(Visibility.GONE))));
