Question

我在做espresso测试时遇到错误

android.view.ViewRootImpl $ CalledFromWrongThreadException：只有创建视图层次结构的原始线程才能触及其视图。在android.view.ViewRootImpl.checkThread（ViewRootImpl.java:6891）在android.view.ViewRootImpl.playSoundEffect（ViewRootImpl.java:5751）在android.view.View.playSoundEffect（View.java:20321）在android.view.View.performClick（View.java:5636） at nz.salect.handset.auth.EntryActivityUITest.should_open_logDetails_activity_when_pressing_logDetails_button（EntryActivityUITest.kt：47）

第47行是第二次测试中的代码，它尝试执行单击操作。

第一次测试在第二次失败的地方通过，因为它因例外而无法运行。

@LargeTest
@RunWith(AndroidJUnit4::class)
class EntryActivityUITest {
    @Rule
    @JvmField
    val entryAuthActivityRule = ActivityTestRule(EntryActivity::class.java, true, false)

    @Test
    fun it_should_show_logDetails_buttons_after_starting() {
        entryAuthActivityRule.launchActivity(null)

        Espresso.onView(ViewMatchers.withId(R.id.auth_button_logDetails))
            .check(ViewAssertions.matches(ViewMatchers.isDisplayed()))
    }

    @Test
    fun should_open_logDetails_activity_after_pressing_logDetails_button() {
        entryAuthActivityRule.launchActivity(null)

        val button = entryAuthActivityRule.activity.findViewById<Button>(R.id.auth_button_logDetails)
        button.performClick()

        Espresso.onView(ViewMatchers.withId(R.id.loginDetails_textEdit_password))
            .check(ViewAssertions.matches(ViewMatchers.isDisplayed()))
    }
}

这里发生了什么？以及如何解决？

Answer 1

这两行

    val button = entryAuthActivityRule.activity.findViewById<Button>(R.id.auth_button_logDetails)
    button.performClick()

看起来很可疑。我本来期待像

这样的东西

Espresso.onView(ViewMatchers.withId(R.id.auth_button_logDetails)).perform(ViewActions.click())

在做espresso咖啡测试时如何解决这个CalledFromWrongThreadException？
