[英]Testing toolbar title text with Espresso - Android
我有兩個片段附加到一個活動,並希望測試該活動的工具欄標題。
所以我寫了這個:
@Test
public void testToolbar(){
onView(allOf(instanceOf(TextView.class),withParent(withId(R.id.toolbar))))
.check(matches(withText("Είσοδος/Εγγραφή")));
}
但是,我用inText方法放入的文本無法識別。
android.support.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'with text: is "Είσοδος/Εγγραφή"' doesn't match the selected view.
Expected: with text: is "Είσοδος/Εγγραφή"
這是我的活動代碼。
public class MainActivity extends AppCompatActivity {
public static final String LOGIN_FRAGMENT = "LOGIN_FRAGMENT";
public static final String REGISTER_FRAGMENT = "REGISTER_FRAGMENT";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setTitle("Eίσοδος/Εγγραφή");
LoginFragment loginFragment = new LoginFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(android.R.id.content,loginFragment,LOGIN_FRAGMENT);
fragmentTransaction.commit();
}
public void userReg(View view){
RegisterFragment regFragment = new RegisterFragment();
FragmentManager fragmentManager1 = getSupportFragmentManager();
FragmentTransaction fragmentTransaction1 = fragmentManager1.beginTransaction();
fragmentTransaction1.addToBackStack("added");
fragmentTransaction1.replace(android.R.id.content,regFragment,REGISTER_FRAGMENT);
fragmentTransaction1.commit();
}
}
它是相應的xml文件。
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="team.football.ael.MainActivity"
>
<include
android:id="@+id/toolbar"
layout="@layout/tool_lay"
/>
</RelativeLayout>
這是怎么回事? 一切都在那里。
謝謝,西奧。
onView(withId(R.id.toolbar)).check(matches(hasDescendant(withText("Title"))));
如果您有簡單的工具欄沒有內部TextView。
我假設你的tool_layout
看起來像這樣:
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="?colorPrimary"
android:minHeight="?actionBarSize"
android:popupTheme="@style/ThemeOverlay.AppCompat.Light"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:navigationContentDescription="@string/abc_action_bar_up_description"
app:navigationIcon="?homeAsUpIndicator"
app:title="">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/app_name"/>
</android.support.v7.widget.Toolbar>
這是測試:
onView(withId(R.id.toolbar)).check(matches(isDisplayed()));
onView(withText(R.string.app_name)).check(matches(withParent(withId(R.id.toolbar))));
希望它會有所幫助
我以更通用的方式創建了Espresso Utils Gist ,您可以在其中看到Google不提供的不同匹配器。
用法:
onView(isAssignableFrom(Toolbar.class)).check(matches(withToolbarTitle(R.string.all_name_app)));
用於測試活動標題的Kotlin代碼:
val activityTitleTextView = onView(
allOf(
childAtPosition(
allOf(withId(R.id.action_bar),
childAtPosition(
withId(R.id.action_bar_container),
0)),
0),
isDisplayed()))
activityTitleTextView.check(matches(withText("My Activity Title"))
