Android 开发 Espresso (执行操作View Actions)
在视图上执行操作(View Actions)
当为目标视图找到了合适的适配器后，你将可以通过 perform方法在该视图上执行 ViewAction。
比如点击视图
onView(…).perform(click());
你可以在一个 perform 方法中执行多个操作
onView(…).perform(typeText("Hello"), click());
我们展示一一下目前所有的视图操作
Text类型
- typeText 获得焦点并注入文本
- typeTextIntoFocusedView在已获得焦点的View上注入文本
- clearText 文本清除
- replaceText String 文本替换
@Test
public void testText() throws Exception{
ViewInteraction editText
= onView(withId(R.id.espresso_demo_editText));
editText.perform(typeText("TiaoPi")
,clearText()
,typeText("TiaoPi22222222")
,typeTextIntoFocusedView("TiaoPi")
,replaceText("XinXinXinTiaoPi"));
}
Click/Press 类型
- click点击
- doubleclick双击
- longclick长按
- pressIMEActionButton()
- pressKey([int/EspressoKey]) 物理按键
- pressMenuKey菜单键 点击
- pressBack后退键 点击
- closeSoftKeyboard关闭键盘
- openLink 链接点击
演示最常用的
@Test
public void clickTest() throws Exception{
ViewInteraction button8 = onView(withId(R.id.button8));
ViewInteraction button9 = onView(withId(R.id.button9));
button8.perform(click(),longClick());
button9.perform(doubleClick());
}
Gestures类型
- scrollTo 滑动到指定View
- swipeXX 向XX方向滑动
scrollTo()
swipeLeft()
swipeRight()
swipeUp()
swipeDown()
我们写个List测试一下
@Test
public void testGestures(){
ViewInteraction expressoH = onView(withId(R.id.expresso_RecyclerView_h));
ViewInteraction expressoV = onView(withId(R.id.expresso_RecyclerView_v));
expressoH.perform(swipeRight());
expressoH.perform(swipeLeft());
expressoV.perform(swipeUp(),swipeDown());
//休眠再去找这个
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
expressoV
.perform(RecyclerViewActions.actionOnItem(
hasDescendant(withText(String.valueOf(20))), scrollTo()));
}
关于RecyclerView
需要加入espresso-contrib进行测试
androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.0') {
exclude group: 'com.android.support', module: 'appcompat'
exclude group: 'com.android.support', module: 'support-v4'
exclude module: 'recyclerview-v7'
}
