android - 获取 java.lang.RuntimeException：通过 Maven 运行 Robolectric 时的存根

Question

好吧，我遇到了一个奇怪的错误。当我通过 IntelliJ 运行测试时，它毫无问题地通过了。但是，如果我使用 sure-fire 插件或“mvn clean test”命令运行它，我会得到以下异常：

shouldLoadMoreDataOnScrollBeyondTheThreshold(br.com.cybereagle.androidwidgets.listener.EndlessScrollListenerTest)  Time elapsed: 2.73 sec  <<< ERROR!

这是我的测试：

@RunWith(RobolectricTestRunner.class)
@Config(manifest = Config.NONE)
public class EndlessScrollListenerTest {

    private ListView listView;
    private EndlessScrollListener endlessScrollListener;

    @Before
    public void setUp() throws Exception {
        listView = mock(ListView.class);

        when(listView.getHeaderViewsCount()).thenReturn(0);
        when(listView.getFooterViewsCount()).thenReturn(0);


        endlessScrollListener = spy(new TestEndlessScrollListener(5));
    }

    @Test
    public void shouldLoadMoreDataOnScrollBeyondTheThreshold() {
        doReturn(true).when(endlessScrollListener).hasMoreDataToLoad();

        assertTrue(endlessScrollListener.isLoading());

        endlessScrollListener.onScroll(listView, 2, 5, 20);

        assertFalse(endlessScrollListener.isLoading());

        endlessScrollListener.onScroll(listView, 15, 5, 20);

        assertTrue(endlessScrollListener.isLoading());


        endlessScrollListener.onScroll(listView, 21, 5, 40);

        assertFalse(endlessScrollListener.isLoading());

        endlessScrollListener.onScroll(listView, 35, 5, 40);

        assertTrue(endlessScrollListener.isLoading());

        endlessScrollListener.onScroll(listView, 38, 5, 60);

        assertFalse(endlessScrollListener.isLoading());

        doReturn(false).when(endlessScrollListener).hasMoreDataToLoad();

        endlessScrollListener.onScroll(listView, 55, 5, 60);

        assertFalse(endlessScrollListener.isLoading());


        verify(endlessScrollListener, atMost(6)).hasMoreDataToLoad();
        verify(endlessScrollListener, times(1)).loadMoreData(1);
        verify(endlessScrollListener, times(1)).loadMoreData(2);
        verify(endlessScrollListener, never()).loadMoreData(3);
    }

    private static class TestEndlessScrollListener extends EndlessScrollListener {

        private TestEndlessScrollListener(int visibleThreshold) {
            super(visibleThreshold);
        }

        @Override
        protected boolean hasMoreDataToLoad() {
            return false;
        }

        @Override
        protected void loadMoreData(int page) {

        }
    }
}

错误发生在第一个 assertTrue 中：

assertTrue(endlessScrollListener.isLoading());

最奇怪的是，根据堆栈跟踪，它发生在 assertTrue 方法内部。

这些是我的 Maven 依赖项：

<dependencies>
    <dependency>
        <groupId>android</groupId>
        <artifactId>android</artifactId>
        <version>${android.version}</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>com.google.android</groupId>
        <artifactId>support-v4</artifactId>
        <version>${support.v4.version}</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>com.google.android</groupId>
        <artifactId>support-v7-appcompat</artifactId>
        <version>${support.v7.version}</version>
        <scope>provided</scope>
        <type>jar</type>
    </dependency>

    <dependency>
        <groupId>org.robolectric</groupId>
        <artifactId>robolectric</artifactId>
        <version>${robolectric.version}</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.hamcrest</groupId>
        <artifactId>hamcrest-core</artifactId>
        <version>1.2</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.8.2</version>
        <scope>test</scope>
    </dependency>
</dependencies>

正如我所说，它在 IntelliJ 内部工作。

另一个细节是我有另一个项目生成一个 JAR，该 JAR 通常使用来自 IntelliJ 和 Maven 的 Robolectric。

知道发生了什么吗？

好吧，我的问题是我从错误的包中导入：

import static junit.framework.Assert.assertFalse;
import static junit.framework.Assert.assertTrue;

我将其更改为：

import static org.junit.Assert.assertFalse;
import static org.junit.Assert.assertTrue;

现在它按预期工作。我不知道为什么它在 IntelliJ 中工作。

That is silly but moving dependency of junit and put it before android dependencies will solve your issue. So your maven should be like this:

depndencies
-junit
-android

将 junit 依赖项向上移动到您引用的库上，它将起作用。看这里
