标签: android-espresso

我正在尝试在Espresso仪器测试中设置Dagger,以模拟对外部资源的调用(在这种情况下为RESTful服务).我在Robolectric中为我的单元测试所遵循的模式是扩展我的生产Application类并使用将返回模拟的测试模块覆盖Dagger模块.我试图在这里做同样的事情,但是当我尝试将应用程序转换为我的自定义应用程序时,我在Espresso测试中遇到了ClassCastException.

这是我到目前为止的设置:

生产

在app/src/main/java/com/mypackage/injection下我有:

MyCustomApplication

package com.mypackage.injection;

import android.app.Application;

import java.util.ArrayList;
import java.util.List;

import dagger.ObjectGraph;

public class MyCustomApplication extends Application {

    protected ObjectGraph graph;

    @Override
    public void onCreate() {
        super.onCreate();

        graph = ObjectGraph.create(getModules().toArray());
    }

    protected List<Object> getModules() {
        List<Object> modules = new ArrayList<Object>();
        modules.add(new AndroidModule(this));
        modules.add(new RemoteResourcesModule(this));
        modules.add(new MyCustomModule());

        return modules;
    }

    public void inject(Object object) {
        graph.inject(object);
    }
}

我用以下方式使用:

BaseActivity

package com.mypackage.injection.views;

import android.app.Activity;
import android.os.Bundle;

import com.mypackage.injection.MyCustomApplication;

public abstract class MyCustomBaseActivity extends Activity {

    @Override
    protected void …

有没有可靠的方法让Espresso等待WebViews完成加载？

我尝试过这里概述的方法,但发现它不可靠.它还有其他缺点:

• 它依赖于替换WebView的WebChromeClient.由于WebViewrt由于某种原因没有getWebChromeClient()方法,因此无法包装任何现有的WebChromeClient.
• 它需要一个特定的WebView实例,因此每次我使用WebView启动一个Activity时,我必须获取WebView实例并为其注册一个新的WebviewIdlingResource.

我希望有人有一个没有任何这些缺点的解决方案.我曾希望espresso-web软件包可以提供解决方案,但它似乎没有提供与加载有关的任何内容.

我正在使用浓缩咖啡进行测试,但有时我会尝试从外部存储中获取图像,并且使用棉花糖我需要运行时权限,否则会出现异常崩溃并且测试将失败.

androidTestCompile 'com.android.support.test:runner:0.4'
androidTestCompile 'com.android.support.test:rules:0.4'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.1') {
    // this library uses the newest app compat v22 but the espresso contrib still v21.
    // you have to specifically exclude the older versions of the contrib library or
    // there will be some conflicts
    exclude group: 'com.android.support', module: 'appcompat'
    exclude group: 'com.android.support', module: 'support-v4'
    exclude module: 'recyclerview-v7'
}
androidTestCompile 'junit:junit:4.12'
androidTestCompile 'com.squareup.retrofit:retrofit-mock:1.9.0'
androidTestCompile 'com.squareup.assertj:assertj-android:1.1.0'
androidTestCompile 'com.squareup.spoon:spoon-client:1.2.0'

我该如何管理呢？

我应该为运行时权限编写测试,还是有办法禁用它进行测试？

在测试运行之前,我应该像她在这里说的那样给出权限吗？https://www.youtube.com/watch?list=PLWz5rJ2EKKc-lJo_RGGXL2Psr8vVCTWjM&v=C8lUdPVSzDk

我在动作栏中有一个菜单,我通过以下方式创建:

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    menu.add(Menu.NONE, 98,Menu.NONE,R.string.filter).setIcon(R.drawable.ic_filter_list_white_48dp).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
    menu.add(Menu.NONE, 99,Menu.NONE,R.string.add).setIcon(R.drawable.ic_add_white_48dp).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);


    getMenuInflater().inflate(R.menu.menu_main, menu);

    return true;
}

和menu_main.xml看起来像:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity">
    <item
        android:id="@+id/action_settings"
        android:title="@string/action_settings"
        android:orderInCategory="100"
        app:showAsAction="never"
        android:icon="@drawable/ic_settings_white_48dp"/>
</menu>

在Espresso中测试时,我想点击"添加"图标(menuId 99).我试过了

@Test
public void testAdd() {
openActionBarOverflowOrOptionsMenu(InstrumentationRegistry.getTargetContext());
    onView(withText(R.string.add)).perform(click());
}

但是这会因NoMatchingViewException而失败.(设置项,直接在xml中定义,我可以使用相同的代码单击.)

这是针对targetSdkVersion 23和AppCompatActivity的.工具栏的相关行是:

Toolbar toolbar = (Toolbar) findViewById(R.id.tool_bar);
setSupportActionBar(toolbar);
if( getSupportActionBar() != null ) {
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

和tool_bar.xml看起来像:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar     xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark"
    android:background="@color/ColorPrimary"
    android:elevation="4dp"
    tools:ignore="UnusedAttribute">
</android.support.v7.widget.Toolbar>

在我的build.gradle文件中,我有支持库依赖项:

compile "com.android.support:appcompat-v7:22.2.0"
compile "com.android.support:recyclerview-v7:22.2.0"
compile "com.android.support:design:22.2.0"

我也有espresso测试的依赖项:

androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2'

此时一切都运行良好,但是当我添加依赖项时,espresso-contrib我得到了InflateException我的RecyclerView

我正在尝试根据我的功能编写espresso函数以匹配第一个espresso找到的元素,即使找到了多个匹配的项目.

例如:我有一个包含商品价格的单元格的列表视图.我希望能够将货币兑换成加元并验证商品价格是否为加元.

我正在使用这个功能:

    onView(anyOf(withId(R.id.product_price), withText(endsWith("CAD"))))
        .check(matches(
                isDisplayed()));

这会抛出AmbiguousViewMatcherException.

在这种情况下,我不关心有多少或几个单元格显示CAD,我只想验证它是否显示.有没有办法让espresso在遇到符合参数的物体时立即通过此测试？

我正在Android Studio 0.5.0用Gradle 1.11.我正在尝试从com.jakewharton.espresso安装Espresso库 :espresso:1.1-r2.由于某些原因,AS在项目同步后无法识别Espresso类.所以每次我尝试导入的时间import static com.google.android.apps.common.testing.ui.espresso.Espresso.onView;内androidTest文件的文件夹它标记为无效.

这是我的build.gradle:

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.2'

    defaultConfig {
        minSdkVersion 14

        targetSdkVersion 19
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "com.google.android.apps.common.testing.testrunner.GoogleInstrumentationTestRunner"
    }

    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }

    compile 'com.squareup.dagger:dagger:1.2.1'

    androidTestCompile ('com.jakewharton.espresso:espresso:1.1-r2') {
        exclude group: 'com.squareup.dagger'
    }
}

我想声明我正在测试的我的Acitivty在执行某些操作时已完成.不幸的是到目前为止,我只是通过在测试结束时添加一些睡眠来断言它.有没有更好的办法 ？

我在androidTest文件夹中创建了一个虚拟活动,并在androidTest文件夹中的AndroidManifest文件中声明了该活动.

我的基本目的是通过使用framelayout容器将其放入虚拟活动来测试可重用片段.
