android - android.support.test.espresso.InjectEventSecurityException 当我尝试使用 espresso 填充几个编辑文本时抛出

Question

这是我的代码：

onView(withId(R.id.first_name)).perform(
                typeText("John"), closeSoftKeyboard());
SystemClock.sleep(5000);
onView(withId(R.id.last_name)).perform(typeText("Smith"));

我从这里尝试了答案 Android :java.lang.SecurityException: Injecting to another application requires INJECT_EVENTS 权限 ，但没有帮助。

以下是我使用的 expresso 版本：

// Android Test Support Libraries
    espressoRunnerVersion = "0.5"
    espressoRulesVersion = "0.5"
    espressoVersion = "2.2.2"

这是完整的堆栈跟踪：

我尝试过睡眠和不睡眠，也尝试将 closeSoftKeyboard 移到执行操作之外。

Answer 1

在行上放置一个断点

onView(withId(R.id.first_name)).perform(typeText("John"), closeSoftKeyboard());

当您越过那条线时，您是否看到自动完成弹出框？如果是这样，问题在于弹出框正在更改 EditText 的焦点，并且您当时正尝试执行 typeText 方法。

最简单的解决方案：将 typeText() 替换为 replaceText()。键盘不会显示，但如果您的集成测试没有在键盘显示期间测试 UI 放置，这将起作用。它应该看起来像：

onView(withId(R.id.first_name)).perform(replaceText("John"));
