[英]NoClassDefFoundError for Android Espresso internal dagger factory class
[英]Android Espresso with Dagger
我正在尝试使用Espresso特别是Double-Espresso库运行android仪器测试。
我知道Espresso已经依赖于dagger 1.2.1而我的应用也使用相同的匕首版本。 所以我声明了这样的依赖。
// dagger-compiler already includes dagger.
compile 'com.squareup.dagger:dagger-compiler:1.2.1'
androidTestCompile 'com.google.guava:guava:16.0'
androidTestCompile 'javax.annotation:javax.annotation-api:1.2'
androidTestCompile 'com.google.code.findbugs:jsr305:1.3.9'
androidTestCompile('com.jakewharton.espresso:espresso-support-v4:1.1-r3') {
exclude group: 'com.android.support', module: 'support-v4'
exclude group: 'com.google.guava', module: 'guava'
exclude group: 'com.squareup.dagger'
//exclude group: 'javax.annotation', module: 'javax.annotation-api'
}
我的测试看起来像这样。
@LargeTest
public class IntegrationTest extends ActivityInstrumentationTestCase2<LoginSelectMethodActivity> {
public IntegrationTest() {
// This constructor was deprecated - but we want to support lower API levels.
super("com.google.android.apps.common.testing.ui.testapp", LoginSelectMethodActivity.class);
}
@Override
public void setUp() throws Exception {
super.setUp();
getActivity();
}
@LargeTest
public void test_actionButtonEnableWhenInputsAreValid() {
Espresso.onView(ViewMatchers.withId(R.id.signin_email))
.perform(ViewActions.click());
Espresso.onView(ViewMatchers.withText(R.id.et_email))
.perform(ViewActions.typeText("valid@email.com"), ViewActions.pressKey(KeyEvent.KEYCODE_ENTER),
ViewActions.typeText("aGoodP455w0rd"), ViewActions.pressKey(KeyEvent.KEYCODE_ENTER));
Espresso.onView(ViewMatchers.withId(R.id.b_signin))
.check(matches(withText(R.string.sign_in)));
}
}
然而,测试失败,日志说它找不到匕首的方法之一。

我在Android Studio中使用GoogleInstrumentationTestRunner
运行测试。 希望任何人都可以为此给我一些启示。
你需要依靠匕首。
替换这个:
// dagger-compiler already includes dagger.
compile 'com.squareup.dagger:dagger-compiler:1.2.1'
有了这个:
compile 'com.squareup.dagger:dagger:1.2.1'
provided 'com.squareup.dagger:dagger-compiler:1.2.1'
