How to use espresso to press a AlertDialog button

Question

I want to press below button using Espresso, but I'm not sure how. Should I get the resource-id? Or how to set an ID to the AlertDialog??

@RunWith(AndroidJUnit4.class)
public class ApplicationTest {

@Rule
public ActivityTestRule<LoadingActivity> mActivityRule =
        new ActivityTestRule<>(LoadingActivity.class);

@Test
public void loginClickMarker() {
//Doesn't work:
    onView(withText("GA NAAR INSTELLINGEN")).perform(click());
}
}

public class PopupDialog {

public static void showGPSIsDisabled(Context context, String msg, final PopupDialogCallback popupDialogCallback) {
    new AlertDialog.Builder(context)
            .setTitle(context.getString(R.string.location_turned_off))
            .setMessage(msg)
            .setPositiveButton(context.getString(R.string.go_to_settings), new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                    popupDialogCallback.hasClicked();
                }
            }).show();
}
}

android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with text: is "GA NAAR INSTELLINGEN"

Solution 1

According to StackOverflow similar issue: Check if a dialog is displayed with Espresso

You should change your code from:

onView(withText("GA NAAR INSTELLINGEN")).perform(click());

to

onView(withText("GA NAAR INSTELLINGEN")))
    .inRoot(isDialog()) // <---
    .check(matches(isDisplayed()))
    .perform(click());

If it won't work, don't bother to use long with Espresso another great Google's instrumentation test called uiatomator.

Check: http://qathread.blogspot.com/2015/05/espresso-uiautomator-perfect-tandem.html

Example code:

// Initialize UiDevice instance
UiDevice uiDevice = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());

// Search for correct button in the dialog.
UiObject button = uiDevice.findObject(new UiSelector().text("GA NAAR INSTELLINGEN"));
if (button.exists() && button.isEnabled()) {
    button.click();
}

Hope it will help

Solution 2

Since inRoot(isDialog()) does not seem to work for DialogFragment I use this workaround so far:

enum class AlertDialogButton(@IdRes val resId: Int) {
    POSITIVE(android.R.id.button1),
    NEGATIVE(android.R.id.button2),
    NEUTRAL(android.R.id.button3)
}

fun clickOnButtonInAlertDialog(button: AlertDialogButton) {
    onView(withId(button.resId)).perform(click())
}

Solution 3

You might need to close the softkeyboard like this:

        onView(withId(R.id.username))
                .perform(typeText("username"))
                .perform(closeSoftKeyboard())
        onView(withId(android.R.id.button1)).perform((click()))

As detailed more thoroughly by this answer.

Solution 4

For an AlertDialog, the id assigned for each button is:

• POSITIVE: android.R.id.button1
• NEGATIVE: android.R.id.button2
• NEUTRAL: android.R.id.button3

You can check yourself in the AlertController class, setupButtons() method. So you can perform a click as follows:

onView(withId(android.R.id.button1)).perform(click());

Solution 5

The good thing about the last update is it allows you to set permissions before each test, so that you don't have to click the dialog (this speeds up testing by a lot!)

Use the following rule (e.g. for location/storage.. substitute these with the permissions you need obviously)

@Rule
  public GrantPermissionRule runtimePermissionRule = GrantPermissionRule.grant(
      ACCESS_FINE_LOCATION, READ_EXTERNAL_STORAGE);

I think you could use the withText() method instead of matching by id

onView(withText("GA NAAR INSTELLINGEN")).perform(click()); doesn't work

Thank you! isDialog() wasn't working for me, but I was able to find button1 and button2. Thank you for explicitly writing out how the different buttons line up with their ID numbers.

I don't know if it's a new thing or not, but androidx.test.espresso.action.ViewActions has a method `closeSoftKeyboard()'

[Safety]

For me this the best solution.

[Taslim Oseni]

This worked for me without the check() method.
