android – onWebView在层次结构中找不到匹配的视图：启用了JS的WebView

概述我正在尝试一些基本的webView测试： public class TheMainActivity { @Rule public ActivityTestRule<MainActivity> activityTestRule = new ActivityTestRule<MainActivity>(MainActivity.class, false, false) { 我正在尝试一些基本的webVIEw测试：

public class TheMainActivity {    @Rule    public ActivityTestRule<MainActivity> activityTestRule = new ActivityTestRule<MainActivity>(MainActivity.class,false,false) {        @OverrIDe        protected voID afteractivityLaunched() {            onWebVIEw().forceJavaScriptEnabled();        }    };    @Test    public voID theIntroductionShouldShow() {        activityTestRule.launchActivity(null);        onWebVIEw().check(webMatches(getText(),containsstring("SURVIVAL ACTIONS")));    }}

关于这个文档 – 但我得到：

有趣的是,当我在MainActivity中设置启用JavaScript时(尽管我不希望这样,而forceJavaScriptEnabled()应该对文档进行测试)然后我这样做：

…

解决方法 onWebVIEw()方法用作视图匹配器isJavaScriptEnabled(),直到您激活它才能匹配.相反,你可以调用onWebVIEw(myMatcher)然后它应该工作. espresso文档在这里看起来有点不正确.

对于您的第二条错误消息,我还没有解释.
