的答案是使用「預期」的方法測試代碼後,驗證活動的結果符合您的要求,看起來像這樣:
@Test
public void typeNumber_ValidInput_InitiatesCall() {
// Types a phone number into the dialer edit text field and presses the call button.
onView(withId(R.id.edit_text_caller_number))
.perform(typeText(VALID_PHONE_NUMBER), closeSoftKeyboard());
onView(withId(R.id.button_call_number)).perform(click());
// Verify that an intent to the dialer was sent with the correct action, phone
// number and package. Think of Intents intended API as the equivalent to Mockito's verify.
intended(allOf(
hasAction(Intent.ACTION_CALL),
hasData(INTENT_DATA_PHONE_NUMBER),
toPackage(PACKAGE_ANDROID_DIALER)));
}
但是,作爲一個完全自動化測試的一部分,你需要將活動的響應也刪除,以便它可以在沒有實際阻止用戶輸入的情況下運行。您需要設置inten運行測試上前t存根:
@Before
public void stubAllExternalIntents() {
// By default Espresso Intents does not stub any Intents. Stubbing needs to be setup before
// every test run. In this case all external Intents will be blocked.
intending(not(isInternal())).respondWith(new ActivityResult(Activity.RESULT_OK, null));
}
然後,你可以這樣寫測試的相應部分:
@Test
public void pickContactButton_click_SelectsPhoneNumber() {
// Stub all Intents to ContactsActivity to return VALID_PHONE_NUMBER. Note that the Activity
// is never launched and result is stubbed.
intending(hasComponent(hasShortClassName(".ContactsActivity")))
.respondWith(new ActivityResult(Activity.RESULT_OK,
ContactsActivity.createResultData(VALID_PHONE_NUMBER)));
// Click the pick contact button.
onView(withId(R.id.button_pick_contact)).perform(click());
// Check that the number is displayed in the UI.
onView(withId(R.id.edit_text_caller_number))
.check(matches(withText(VALID_PHONE_NUMBER)));
}
如果需要從其他應用程序(如電話撥號與實際用戶輸入驗證),這超出了Espresso的範圍。由於我目前與一家幫助處理這類案件的供應商合作,我不願意提供名稱和工具,但很多人確實需要編寫模擬真實端到端體驗的測試。
邁克埃文斯有一個很好的關於測試意圖here的文章,並且總是有android文檔here。
我真的很感激你的答案,但我正在尋找解決問題的方法,我們使用startActivity而不是startActivityForResult啓動撥號器活動。我曾經使用過類似的策略來嘲笑Camera Intent – cammando
