OnClickListener 从未使用 espresso 调用执行单击

Question

我想在现有项目上首次测试浓缩咖啡。在我的HomeFragment包含的中HomeActivity，我在显示另一个视图的按钮上设置了 OnClickListener，我在模拟器中运行该应用程序，一切正常。然后我想用浓缩咖啡测试它，但我的 OnClickListener 似乎从未被调用。我在开发者选项中删除了模拟器中的动画选项，但 espresso 测试仍然失败，并且日志确认 onClick 从未被调用。

android.support.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError：“在屏幕上向用户显示”与所选视图不匹配。

预期：显示在屏幕上给用户

得到：“FilterPopupView {id = 2131558573，res-name = filter_view，可见性= GONE，宽度= 0，高度= 0，has-focus = false，has-focusable = false，has-window-focus = true，可点击=假、 is-enabled = true、 is-focused = false、 is-focusable = false、 is-layout-requested = true、 is-selected = false、 root-is-layout-requested = false、 has-input-connection =假，x=0.0，y=0.0，子计数=1}”

在HomeActivityTest

public class HomeActivityTest
        extends ActivityInstrumentationTestCase2<HomeActivity> {

    public HomeActivityTest() {
        super(HomeActivity.class);
    }

    @Before
    public void setUp() throws Exception {
        super.setUp();
        injectInstrumentation(InstrumentationRegistry.getInstrumentation());
        getActivity();
    }

    public void testOpenFilter() {
        Log.e("Tests", "Check button_filter is clickable");
        onView(withId(R.id.button_filter)).check(matches(isClickable()));
        Log.e("Tests", "Click on button_filter");
        onView(withId(R.id.button_filter)).perform(click());
        Log.e("Tests", "Check filter_view visibility");
        onView(withId(R.id.filter_view)).check(matches(isDisplayed()));
    }
}

在build.gradle

defaultConfig {
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 130
        versionName '3.0-v2'
        multiDexEnabled true
        renderscriptTargetApi 20
        renderscriptSupportModeEnabled true
        vectorDrawables.useSupportLibrary = true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

...
    
dependencies {
    // Espresso core
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2')
        {
            exclude group: 'com.android.support'
        }
    // Android JUnit Runner
    androidTestCompile('com.android.support.test:runner:0.5')
        {
            exclude group: 'com.android.support'
        }
    // JUnit4 Rules
    androidTestCompile('com.android.support.test:rules:0.5')
        {
            exclude group: 'com.android.support'
        }
    ...

}

在HomeFragment

void initFilterButton(View view) {
    mFilterButton = (Button) view.findViewById(R.id.button_filter);
    Log.e("Tests", "initFilterButton");
    mFilterButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.e("Tests", "FilterButton onClick"); // <---- Never shown in logcat
            mFilterPopupView.setVisibility(View.VISIBLE);
        }
    });
}

在我的布局“home_fragment.xml”中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/button_filter"
        style="@style/FilterAccess"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:clickable="true"
        android:text="@string/filter_access" />

    <fr.citylity.citylity.v2.ui.views.FilterPopupView
        android:id="@+id/filter_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:elevation="8dp"
        android:visibility="gone" />

</RelativeLayout>
