“!无效数据” - 我有password.setError(getResources().getString(R.string.incorrect_data));
如果我设置密码无效秀TextView的文本,我需要咖啡来测试它,我写的:
onView(withText(R.string.incorrect_data)).check(matches(isDisplayed()));
但是,这是错误的,我有:
android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with string from resource id: <2131493034>[incorrect_data] value: Invalid data!
If the target view is not part of the view hierarchy, you may need to use Espresso.onData to load it from one of the following AdapterViews:android.widget.ListView{307b4f3a IFED.VC. ......ID -480,0-0,1022 #7f0a004c app:id/left_drawer}
如果我写:onView(withText("Invalid data!")).check(matches(isDisplayed()));
我有:
android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with text: is "Invalid data!"
If the target view is not part of the view hierarchy, you may need to use Espresso.onData to load it from one of the following AdapterViews:android.widget.ListView{307b4f3a IFED.VC. ......ID -480,0-0,1022 #7f0a004c app:id/left_drawer}
我用咖啡2:
import static android.support.test.espresso.assertion.ViewAssertions.matches;
import static android.support.test.espresso.matcher.ViewMatchers.withText;
import static android.support.test.espresso.Espresso.onView;
请帮帮我。
帮助过我:
onView(withId(R.id.password)).check(matches(withError(
getActivity().getString(R.string.incorrect_data))));
private static Matcher<View> withError(final String expected) {
return new TypeSafeMatcher<View>() {
@Override
public boolean matchesSafely(View view) {
if (!(view instanceof EditText)) {
return false;
}
EditText editText = (EditText) view;
return editText.getError().toString().equals(expected);
}
@Override
public void describeTo(Description description) {
}
};
}
我写了咖啡1.x的自定义匹配与之相比对给定值一个TextView的文本颜色。也许你可以采用这种解决方案qazxsw POI的咖啡2.x的
EditText.getError(...)
然后在您的测试案例:
/**
* Returns a matcher that matches {@link TextView}s based on text property value. Note: View's
* text property is never null. If you setText(null) it will still be "". Do not use null
* matcher.
*
* @param integerMatcher {@link Matcher} of {@link String} with text to match
*/
public static Matcher<View> withCurrentTextColor(final Matcher<Integer> integerMatcher) {
checkNotNull(integerMatcher);
return new BoundedMatcher<View, TextView>(TextView.class) {
@Override
public void describeTo(Description description) {
description.appendText("with text color: ");
integerMatcher.describeTo(description);
}
@Override
public boolean matchesSafely(TextView textView) {
return integerMatcher.matches(textView.getCurrentTextColor());
}
};
}
/**
* Returns a matcher that matches {@link TextView} based on it's text property value. Note:
* View's Sugar for withTextColor(is("string")).
*/
public static Matcher<View> withCurrentTextColor(int color) {
return withCurrentTextColor(is(color));
}
咖啡工作在三个步骤1:找到视图:在视图上执行操作,这将触发要验证3结果的行动:检查视图做它做什么。验证行动或结果与提供的一些断言
onView(withId(R.id.text_warning_title)).check(matches(withCurrentTextColor(activity.getResources().getColor(R.color.black_light))));
通过onView(withId(R.id.password_text)).perform(action);
onView(withId(R.id.view_for_expected_outcome)).check(expected outcome)
去看看更多的咖啡。
花了一段时间,但这里的Paushchyk Julia的Java代码科特林版本。
