如何测试搜索视图结果？

Question

测试步骤：

1. 输入要搜索的文本
2. 测试输入文本是否显示在列表中

我的测试：

private static final String TEST_SURNAME = "AnySurname";
private static final String TEST_NAME = "AnyName";
private static final String TEST_FULL_NAME = TEST_SURNAME + " " + TEST_NAME;

@Test
public void searchTestPerson() {
     onView(withId(R.id.searchView)).perform(click());
     onView(withId(android.support.design.R.id.search_src_text)).perform(typeText(TEST_FULL_NAME));
     onData(allOf(withRowString(Person.SURNAME_COLUMN_NAME, TEST_SURNAME), withRowString(Person.NAME_COLUMN_NAME, TEST_NAME)))
                .check(matches(isDisplayed()));
}

文本已成功插入搜索视图中，但在最后一步（onData（））失败，出现此错误：

测试已完成。

您可以使用Resource＃getSystem获取视图

Resources.getSystem().getIdentifier("search_src_text",
    "id", "android")


onView(withId(Resources.getSystem().getIdentifier("search_src_text",
"id", "android"))).perform(clearText(),typeText("enter the text"))
.perform(pressKey(KeyEvent.KEYCODE_ENTER))
