我有一个 Android 活动，我想编写一个单元测试，以验证在onResume活动中检查 Internet 是否可用。
public class MyActivity {
@Override
protected void onResume() {
super.onResume();
setContentView(R.layout.connect_to_server);
// Internet availability check
final IInternetAvailabilityChecker checker = InternetAvailabilityChecker.create(this);
if (!checker.isInternetAvailable())
{
Utils.showMessageBox(this, R.string.app_name,
R.string.internet_not_available);
return;
}
在测试中，我想验证MyActiviy.onResume调用的InternetAvailabilityChecker.create方法。
我该怎么做（使用任何与 Android 兼容的免费模拟框架）？
我尝试为此使用 PowerMock（请参见下面的示例），但是当我尝试运行测试时，我收到MockTest.java:7: package org.powermock.core.classloader.annotations does not exist 之类的错误。

单元测试：
@RunWith(PowerMockRunner.class)
@PrepareForTest( { InternetAvailabilityChecker.class })
public class MyActivityPowerMockTest {
@Test
@Ignore
public void test()
{
final IInternetAvailabilityChecker checker = mock(IInternetAvailabilityChecker.class);
when(checker.isInternetAvailable()).thenReturn(false);
mockStatic(InternetAvailabilityChecker.class);
expect(InternetAvailabilityChecker.create(any(Activity.class))).andReturn(checker);
replay(InternetAvailabilityChecker.class);
final MyActivity objectUnderTest = new MyActivity();
objectUnderTest.onResume();
// Verify that the method InternetAvailabilityChecker.create was called
verify(InternetAvailabilityChecker.class);
// TODO: Verify that Utils.showMessageBox has been invoked
}
}
