我有一个带有多个控件的表单，但分布在多个选项卡上。如果用户单击一个按钮，我希望为单个字段调用验证器功能。

要验证具有@RunWith(AndroidJUnit4::class)
class LoginFragmentTest {
@Test
fun testEmptyFields() {
val mockNavController = mock(NavController::class.java)
val mockGraph = mock(NavGraph::class.java)
mockNavController.graph = mockGraph
val scenario = launchFragmentInContainer(themeResId = R.style.AppTheme) {
LoginFragment().also { fragment ->
// In addition to returning a new instance of our Fragment,
// get a callback whenever the fragment’s view is created
// or destroyed so that we can set the mock NavController
fragment.viewLifecycleOwnerLiveData.observeForever { viewLifecycleOwner ->
if (viewLifecycleOwner != null) {
// The fragment’s view has just been created
Navigation.setViewNavController(fragment.requireView(), mockNavController)
}
}
}
}
scenario.onFragment {
it.run {
val viewsIds =
listOf(R.id.etEmailAddress, R.id.etPassword)
for (viewId in viewsIds) {
onView(ViewMatchers.withId(viewId))
.perform(ViewActions.replaceText(""))
Thread.sleep(500)
onView(ViewMatchers.withId(R.id.btLogin)).check(
ViewAssertions.matches(
CoreMatchers.not(
ViewMatchers.isEnabled()
)
)
)
}
}
}
}
}
类型的单个表单域创建密钥，请将该密钥分配给表单域并在密钥的当前状态上调用FormFieldState方法：
