Question

我在Espresso测试中有这段代码

    onView(withId(R.id.src))
            .perform(click());

    onData(hasToString(startsWith("CCD")))
            .perform(click());

   onView(withId(R.id.src))
           .check(matches(withText(containsString("CCD"))));

我尝试做的是点击Spinner中的项目并检查它是否确实在Spinner中选中。

但我收到此错误：

android.support.test.espresso.base.DefaultFailureHandler $ AssertionFailedWithCauseError：＆＃39; with text：包含＆＃34; CCD＆＃34;＆＃39;的字符串与所选视图不匹配。预期：带文字：包含＆＃34; CCD＆＃34; 得到：＆＃34; AppCompatSpinner {id = 2131558533，res-name = src，visibility = VISIBLE，width = 528，height = 163，has-focus = false，has-focusable = true，has-window-focus = true， is-clickable = true，is-enabled = true，is-focused = false，is-focusable = true，is-layout-requested = false，is-selected = false，root-is-layout-requested = false，has- input-connection = false，x = 0.0，y = 0.0，child-count = 1}＆＃34;

Answer 1

将withText()替换为withSpinnerText()

onView(withId(spinnerId)).perform(click());
onData(allOf(is(instanceOf(String.class)), is(selectionText))).perform(click());
onView(withId(spinnerId)).check(matches(withSpinnerText(containsString(selectionText))));

Answer 2

对我来说非常简单的解决方案.....不使用matcher for CustomSpinner

    onView(withId(R.id.custom_spinner)).perform(click());
 onData(anything()).atPosition(1).perform(click());
 onView(withId(R.id.custom_spinner)).check(matches(withSpinnerText(containsString("yourstring"))));

对于自定义适配器，我要创建一个自定义匹配器：

 onView(withId(R.id.spinner)).perform(click());
 onData(allOf(is(instanceOf(YourCustomClass.class)), withMyValue("Open"))).perform(click());


public static <T> Matcher<T> withMyValue(final String name) {
    return new BaseMatcher<T>() {
        @Override
        public boolean matches(Object item) {
            return item.toString().equals(name);
        }

        @Override
        public void describeTo(Description description) {

        }
    };
}

然后，您必须在自定义类上覆盖toString（）方法。
