使用濃咖啡如何檢查我的警報對話框中的項目數

我有一個警報對話框，顯示一些項目。使用濃咖啡如何檢查我的警報對話框中的項目數

private String[] choices; // populated externally 

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 
    builder.setItems(choices, new DialogInterface.OnClickListener() { 

     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      _callback.onChoiceSelected(which); 
      dialog.dismiss(); 
     } 
    }); 

    _dialog = builder.create();

在不同的情況下（例如，如果你是管理員/客），您將有不同數量的「選擇」。在我的咖啡測試中，我基本上試圖測試出現的項目數量。

public void test_ViewsSetupCorrectly() { 

    onView(withId(R.id.settings)).perform(click()); 
    onView(ViewMatchers.withChild(withClassName(Matchers.equalToIgnoringCase("TextView")))).check(matches(isDisplayed())); 

    /*// What I would ideally like ... but doesn't work as well :(: 
     onView(withClassName(equalToIgnoringWhiteSpace("DialogTitle"))).check(matches(hasProperty("child-count", 
                             is(new Integer(1)) 
                            )));*/ 
}

這些基本上拋出一個異常，像這樣：

我推測昂達電話僅用於執行操作？我沒有必要執行某項操作。任何人都可以幫我實際測試一下嗎？

昂達應該允許檢查爲好。你有沒有嘗試過這樣的事情：onData（allOf（is（instanceOf（String.class）），equalTo（string）））。atPosition（lastExpectedIndex）.check（<你的支票在這裏>）; – Maxwell

我曾在過去類似的問題，但我將我自己的EditText控制的警告對話框。這樣做時，您可以爲要添加到對話框中的視圖對象分配一個ID。

AlertDialog.Builder myDialog = new AlertDialog.Builder(this); 

myDialog.setTitle(R.string.add_comment); 

// Set an EditText view to get user input 
final EditText input = new EditText(this); 
input.setId(R.id.myEditText); 
myDialog.setView(input);

add_comment_text id在res/values的ids.xml文件中指定，然後您可以使用此選項來選擇。

onView(withId(R.id.myEditText)

我知道這是一個很老的文章，但它看起來像你想要的東西是一樣的東西是什麼這個blog post here描述。然後，您可以使用匹配對話框視圖的匹配器訪問對話框，並調用諸如getChildCount()或與對話框相關的類似方法？希望這會幫助別人！

該鏈接似乎已經死亡。 – ThomasW

這就是我想出的方法添加到您使用的任何自定義匹配器庫。

public static Matcher<View> hasChildren(final Matcher<Integer> numChildrenMatcher) { 
     return new TypeSafeMatcher<View>() { 

      /** 
      * matching with viewgroup.getChildCount() 
      */ 
      @Override 
      public boolean matchesSafely(View view) { 
       return view instanceof ViewGroup && numChildrenMatcher.matches(((ViewGroup)view).getChildCount()); 
      } 

      /** 
      * gets the description 
      */ 
      @Override 
      public void describeTo(Description description) { 
       description.appendText(" a view with # children is "); 
       numChildrenMatcher.describeTo(description); 
      } 
     }; 
    }

用法爲：

int numKids = 3; 
onView(withId(R.id.view_pager)).check(matches(allOf(
        isDisplayed(), 
        hasChildren(is(numKids)) 
      )));
