处女座，非常重视代码质量，有代码洁癖。
觉得人活着，很重要的是要开心。所以很重视工作的开不开心，也会努力让团队成员也能工作的开心。
抖音杭州部门很缺人，需要招大量的Android客户端开发同学。欢迎大家投简历，或私聊详情，在不泄密的情况下，我知无不言。
参照https://stackoverflow.com/questions/38182672/robolectric-does-not-execute-runnable
和https://stackoverflow.com/questions/18956117/robolectric-run-handler-post
在testLoadRepos()方法里加了ShadowLooper.runUiThreadTasksIncludingDelayedTasks()，或者其他类似方法，貌似也都无法让handler立即Post消息去执行onSuccess方法。不知道为什么？
public void testLoadRepos() throws Exception {
//Robolectric.flushForegroundThreadScheduler();
RepoModel model = new RepoModel();
final List<Repo> result = new ArrayList<>();
final CountDownLatch latch = new CountDownLatch(1);
// ShadowLooper.runUiThreadTasks();
// ShadowLooper.runUiThreadTasksIncludingDelayedTasks();
// ShadowLooper.pauseMainLooper();
model.loadRepos(new RepoCallback() {
@Override
public void onSuccess(List<Repo> repos) {
result.addAll(repos);
latch.countDown();
}
@Override
public void onFailure(int code, String msg) {
fail();
}
});
// Robolectric.flushForegroundThreadScheduler();
// ShadowLooper.runMainLooperOneTask();
// ShadowLooper.runUiThreadTasks();
ShadowLooper.runUiThreadTasksIncludingDelayedTasks();
latch.await();
assertEquals(1, result.size());
latch.await(2, TimeUnit.SECONDS);
}
你的md里面好像少了目录2和目录7
《Android单元测试: 首先，从是什么开始》
1、所以，写单元测试，就是给你的每个类的每个public方法写对于（应）的测试方法。
2、如果这是一句牢*的话，就放括号（）里吧
因为AndroidStudio太智能了，经常我需要重命名单元测试的package的时候，AndroidStudio会把src的package也给重命名了。
运行RepoModelTest，测试testLoadRepos()方法，发现它会一直在await，结束不了。后来加入log后发现代码没有走到callback的onSuccess里面，所以没有触发latch.countDown()。跟进去RepoModel里面发现是callback.onSuccess(repos)调用的问题，直接调用的话后面是能够运行到callback的onSuccess里面的；但是如果用mUiHandler.post()来调用的话就执行不到run()里面的内容了，这是为什么呢？
无法下载这些库
