如何使用 Espresso 将时间设置为 MaterialDateTimePicker

Question

我正在尝试创建简单的 UI 测试，使用 Espresso 为新创建的项目设置日期。

项目正在使用 https://github.com/wdullaer/MaterialDateTimePicker，但它显示的对话框片段很复杂 UI，没有什么可坚持的。

我想创建自定义 ViewAction 以设置类似于 Espresso 中的 PickerActions 的日期或时间。

有什么建议吗？

Answer 1

我很确定用 Espresso 测试它是不可能的。您可能需要执行此操作另一个名为 uiatomator.

的 UI 测试工具

uiatomator，由 Google 制作的另一个很棒的工具允许您测试 Android 系统功能，如通知和屏幕锁定。您可以将它与 Espresso 测试框架一起使用。

请阅读：Espresso & UIAutomator - the perfect tandem

和这份官方 uiautomator 文档，您可以找到 here。

此外，我已经发现 uiautomator 有一个特殊的 class 用于测试这个 UI 元素，称为 DatePickerHelper.java。

另请查看这篇文章：Crushing Fragmentation using the Factory Design Pattern with UiAutomator 请注意，在本文中，作者对 DatePicker.

执行了 uiatomator 测试

希望对您有所帮助

我为 similar library 编写了这个查看操作。

public static ViewAction setCalendarDatePicker(final DateTime dateTime){
    return new ViewAction() {
        @Override
        public Matcher<View> getConstraints() {
            Matcher standardConstraint = ViewMatchers.isDisplayingAtLeast(90);
            return standardConstraint;
        }

        @Override
        public String getDescription() {
            return "setCalendarDatePicker";
        }

        @Override
        public void perform(UiController uiController, View view) {
            MonthAdapter.CalendarDay day = new MonthAdapter.CalendarDay(dateTime.getMillis());
            DayPickerView datePicker = (DayPickerView) view;
            SimpleMonthAdapter adapter = (SimpleMonthAdapter) datePicker.getAdapter();
            datePicker.goTo(day, false, true, true);
            adapter.onDayClick(null, day);
        }
    };

很确定还有改进的余地，但它确实有效。试一试。

最后我创建了也可以设置时间的 ViewAction，但是它很乱，因为您必须知道对话框中视图的类名，才能与 Matcher 匹配。

  /**
     * Returns a {@link ViewAction} that sets a date on a {@link DatePicker}.
     */
    public static ViewAction setDate(final int year, final int monthOfYear, final int dayOfMonth) {

        return new ViewAction() {

            @Override
            public void perform(UiController uiController, View view) {
                final DayPickerView dayPickerView = (DayPickerView) view;

                try {
                    Field f = null; //NoSuchFieldException
                    f = DayPickerView.class.getDeclaredField("mController");
                    f.setAccessible(true);
                    DatePickerController controller = (DatePickerController) f.get(dayPickerView); //IllegalAccessException
                    controller.onDayOfMonthSelected(year, monthOfYear, dayOfMonth);
                } catch (NoSuchFieldException e) {
                    e.printStackTrace();
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                }
            }

            @Override
            public String getDescription() {
                return "set date";
            }

            @SuppressWarnings("unchecked")
            @Override
            public Matcher<View> getConstraints() {
                return allOf(isAssignableFrom(DayPickerView.class), isDisplayed());
            }
        };

    }

    /**
     * Returns a {@link ViewAction} that sets a time on a {@link TimePicker}.
     */
    public static ViewAction setTime(final int hours, final int minutes) {

        return new ViewAction() {

            @Override
            public void perform(UiController uiController, View view) {
                final RadialPickerLayout timePicker = (RadialPickerLayout) view;

                timePicker.setTime(new Timepoint(hours, minutes, 0));
            }

            @Override
            public String getDescription() {
                return "set time";
            }

            @SuppressWarnings("unchecked")
            @Override
            public Matcher<View> getConstraints() {
                return allOf(isAssignableFrom(RadialPickerLayout.class), isDisplayed());
            }
        };

    }

和用法：

onView(isAssignableFrom(DayPickerView.class)).perform(MaterialPickerActions.setDate(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)));

onView(isAssignableFrom(RadialPickerLayout.class)).perform(MaterialPickerActions.setTime(calendar.get(Calendar.HOUR_OF_DAY), calendar.get(Calendar.MINUTE)));

Answer 4

我在 https://github.com/wdullaer/MaterialDateTimePicker 上投入了一些时间，并根据如何处理日、月和年提出了以下解决方案。

点击日期：

我无法使用 robotium 或 Expresso 处理约会。您需要在 gradle 文件中添加 uiautomator 依赖项。在 gradle 文件

中添加以下行

androidTestCompile 'com.android.support:support-annotations:23.4.0'
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.1'

然后在项目gradle文件中将min sdk升级到18，UiAutomator就可以工作了。

现在可以运行下面的代码来设置日期

     if (Build.VERSION.SDK_INT >= 23) {
                UiDevice device = UiDevice.getInstance(getInstrumentation());

//25 is the index which will click on 26 or 24 you need to figure out which one will work for you
                UiObject allowPermissions = device.findObject(new UiSelector().index(25));
                if (allowPermissions.exists()) {
                    try {
                        allowPermissions.click();
                    } catch (UiObjectNotFoundException e) {
                        Log.e("ERROR",e.toString());
                    }
                }
            }

点击年份:

onView(withId(R.id.date_picker_year)).perform(click());
//If you want to set it as 2018. 
onView(withText("2018")).perform(click());

点击月份：

  //Check how many swipeUp or swipeDown's are 
    onView(withId(R.id.animator)).perform(swipeUp());

Answer 5

我使用了内置的TimePickerDialog。

fun setAlarmTime(){

    val calendar = Calendar.getInstance()

    onView(isAssignableFrom(TimePicker::class.java)).perform(
        PickerActions.setTime(
            calendar.get(Calendar.HOUR_OF_DAY),
            calendar.get(Calendar.MINUTE) + 2
        )
    )
    onView(withText("OK")).perform(click())
}

首先，您应该打开TimePickerDialog，然后使用这段代码。时间将为当前时间 + 2 分钟。设置完成后，点击确定按钮。

这是的 Kotlin 翻译，尽管仅适用于 setDate

import org.hamcrest.Matcher
import org.hamcrest.core.AllOf
import java.lang.reflect.Field

class CustomViewActions {
    companion object {
        fun setDate(year: Int, monthOfYear: Int, dayOfMonth: Int): ViewAction {
            return object: ViewAction {
                override fun getConstraints(): Matcher<View> {
                    return allOf(isAssignableFrom(DayPickerView::class.java), isDisplayed())
                }

                override fun getDescription(): String {
                    return "set date"
                }

                override fun perform(uiController: UiController?, view: View?) {
                    try {
                        var f: Field? = null;
                        f = DayPickerView::class.java.getDeclaredField("mController")
                        f.isAccessible = true
                        val controller: DatePickerController = f.get(view) as DatePickerController
                        controller.onDayOfMonthSelected(year, monthOfYear, dayOfMonth)
                    } catch (e: NoSuchFieldException) {
                        e.printStackTrace()
                    } catch (e: IllegalAccessException) {
                        e.printStackTrace()
                    }
                }

            }


        }
    }
}

onView(isAssignableFrom(DayPickerView::class.java)).perform(CustomViewActions.setDate(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)));

我在 Android Studio 中使用 LayoutInspector 检查了视图的 ID。如果他们在未来的版本中不会改变，这些是 ID 及其对我的工作方式：

public static void setDate(LocalDate date){
    onView(withTagValue((Matchers.is((Object) ("TOGGLE_BUTTON_TAG"))))).perform(click());
    onView(withId(com.google.android.material.R.id.mtrl_picker_text_input_date)).perform(replaceText(date.format(DateTimeFormatter.ofPattern("M/d/yy"))));
}

public static void setTime(LocalTime time){
    onView(withId(com.google.android.material.R.id.material_timepicker_mode_button)).perform(click());
    onView(withId(com.google.android.material.R.id.material_hour_text_input)).perform(click());
    onView(allOf(isDisplayed(), withClassName(is(AppCompatEditText.class.getName())))).perform(replaceText(time.format(DateTimeFormatter.ofPattern("hh"))));
    onView(withId(com.google.android.material.R.id.material_minute_text_input)).perform(click());
    onView(allOf(isDisplayed(), withClassName(is(AppCompatEditText.class.getName())))).perform(replaceText(time.format(DateTimeFormatter.ofPattern("mm"))));
}
