如何使用 Espresso 将时间设置为 MaterialDateTimePicker

How to set time to MaterialDateTimePicker with Espresso

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?

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)));

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());

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

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"))));
}
