在Dalvik运行时设备上运行Espresso仪器测试的问题

Question

我正在遇到类似的问题,FragmentActivity无法通过ActivityInstrumentationTestCase2进行测试

顶级解决方案存在的问题仅适用于使用Eclipse构建系统.我正在使用Gradle作为我的项目.

在运行ART运行时的Nexus 5上,我的Espresso仪器测试运行完美.当我在Dalvik运行时或模拟器上使用Nexus 4时,我遇到了在测试框架之外运行应用程序时不会发生的异常.

java.lang.NoClassDefFoundError: com.packagename.fragment.ProgressDialogFragment

在日志中,我发现这些可疑消息类似于链接的问题:

ProgressDialogFragment是其子DialogFragment2类,是Android支持库DialogFragment类的子类

以下是我的Gradle文件中的依赖项,如果这有帮助:

    compile 'com.android.support:support-v4:+'
    compile 'com.android.support:appcompat-v7:+'

    compile 'com.google.android.gms:play-services:+'

    compile 'com.google.code.findbugs:jsr305:+'

    apt "com.jakewharton:butterknife:${project.ext.butterKnifeVersion}"
    compile "com.jakewharton:butterknife:${project.ext.butterKnifeVersion}"

    compile fileTree(dir: 'libs', include: '*.jar')

    // Excluded modules were determined from here: https://github.com/robolectric/deckard-gradle
    instrumentTestCompile fileTree(dir: 'libs-test', include: '*.jar')
    instrumentTestCompile 'com.google.guava:guava:14.0.1',
            'com.squareup.dagger:dagger:1.1.0',
            'org.hamcrest:hamcrest-integration:1.1',
            'org.hamcrest:hamcrest-core:1.1',
            'org.hamcrest:hamcrest-library:1.1'

    instrumentTestCompile('junit:junit:4.11') {
        exclude module: 'hamcrest-core'
    }
    instrumentTestCompile('org.robolectric:robolectric:2.3-SNAPSHOT') {
        exclude module: 'classworlds'
        exclude module: 'maven-artifact'
        exclude module: 'maven-artifact-manager'
        exclude module: 'maven-error-diagnostics'
        exclude module: 'maven-model'
        exclude module: 'maven-plugin-registry'
        exclude module: 'maven-profile'
        exclude module: 'maven-project'
        exclude module: 'maven-settings'
        exclude module: 'nekohtml'
        exclude module: 'plexus-container-default'
        exclude module: 'plexus-interpolation'
        exclude module: 'plexus-utils'
        exclude module: 'wagon-file'
        exclude module: 'wagon-http-lightweight'
        exclude module: 'wagon-http-shared'
        exclude module: 'wagon-provider-api'
    }
    instrumentTestCompile 'org.mockito:mockito-core:1.9.+'

所以我的问题是如何确保在应用程序APK和测试APK之间使用相同的支持库？我已经尝试添加instrumentTestCompile 'com.android.support:support-v4:+'以确保相同的支持库版本,但这没有帮助.

经过多次痛苦,汗水和眼泪.我设法确定了解决方案.简单地添加exclude group: 'com.android.support', module: 'support-v4'到Robolectric的排除列表允许Robolectric继续工作,同时让它不会在Dalvik运行时崩溃.
