如果我在espresso测试用例运行时手动启动应用程序，它会工作，测试通过。但如果我等待应用程序通过espresso自动启动，它会失败，并显示以下信息。
有什么需要帮忙的。先谢了。

测试代码：

@RunWith(AndroidJUnit4::class)
@LargeTest
class CSVParserActivityTest {

    @get:Rule
    var activityScenarioRule: ActivityScenarioRule<CSVParserActivity> = ActivityScenarioRule(
        CSVParserActivity::class.java
    )

    @Test
    fun checkFIlePickerDialogTitle() {
        onView(withId(R.id.title)).check(matches(AllOf.allOf(withText("Choose a CSV file"))))
    }
}

器械详细信息：
