当我在 Android 应用程序上使用自定义布局或自定义组件测试 Activity 或 fragment 时，Robolectric 单元测试出现“ClassCastException”。 例子 : CrumbView 扩展了 LinearLayout。当我启动 fragment 时出现错误: java.lang.ClassCastException:com.app.test.ui.view.CrumbView 无法转换为 com.app.test.ui.view.CrumbView 有人知道如何修复它吗？或者 Robolectric 尚不支持？
java.lang.ClassCastException: com.app.test.ui.view.DrawerView cannot be cast to com.app.test.ui.view.DrawerView

onCreate(EquipementsActivity.java:61) 线指向: DrawerView抽屉 View = findViewById(R.id.drawer);
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_equipements);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = findViewById(R.id.drawer_layout);
DrawerView drawerView = findViewById(R.id.drawer);
ActionBarDrawerToggle toggle .......
最佳答案
只需将“com.app.test.ui.view.”添加到 @PowerMockIgnore 即可进行单元测试。 例如: @PowerMockIgnore({"org.mockito.", "org.robolectric.", "android.", "com.app.test.ui.view.*"})
