自Android Lollipop问世以来,我在使用新的Appcompat支持库时无法运行Robolectic测试.我跟着:

• https://github.com/robolectric/deckard-gradle
• https://chris.banes.me/2014/10/17/appcompat-v21/

我目前的进展如下:https://github.com/fada21/android-tdd-bootstrap

我的配置(蒸馏)是:

android {
  compileSdkVersion 21
  buildToolsVersion "21.0.1"

defaultConfig {
  applicationId "com.fada21.android.bootstrap"
  minSdkVersion 15
  targetSdkVersion 21

...

dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile 'com.android.support:support-v4:21.0.0'
  compile 'com.android.support:appcompat-v7:21.0.0'

...

androidTestCompile('org.robolectric:robolectric:2.4-SNAPSHOT') {

我在这里提出了一个问题:https://github.com/robolectric/robolectric/issues/1332(详情请看这里).

这是我得到的错误:

java.lang.RuntimeException: Could not find any resource  from reference ResName{com.fada21.android.bootstrap:style/Theme_AppCompat_Light_NoActionBar} from style StyleData{name='AppTheme', parent='Theme_AppCompat_Light_NoActionBar'} with theme null

我正在尝试测试我的 recyclerView 并且我正在使用材料卡视图进行项目显示，虽然该应用程序运行良好，但当我尝试测试时出现此错误：

android.view.InflateException: Binary XML file line #11: Binary XML file line #11: Error inflating class com.google.android.material.card.MaterialCardView
Caused by: android.view.InflateException: Binary XML file line #11: Error inflating class com.google.android.material.card.MaterialCardView
Caused by: java.lang.reflect.InvocationTargetException
...
Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).

现在测试就这么简单：

  @Test
    fun shouldShowList() {
        launchFragmentInContainer<PostsFragment>()
        Thread.sleep(5000)
    }

睡眠仅用于应用程序等待尝试显示列表。奇怪的是，当我的列表项布局不使用 materialCardView 时，测试通过了。现在我已将我的应用主题更改为：

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">

但测试仍然消失，那么如何更改我的应用程序的测试主题？
