Question

我有一个适用于Android的简单Espresso测试，在“活动”切换之前，该测试正常进行。该测试通过登录运行，按类从Web视图中选择元素，然后在成功登录后切换活动。一旦进入新的Activity，就无法通过类，css选择器或x_path在新的webview中找到任何内容。

我知道这是隐藏在html中的，我可以看到它并在chrome insepctor中搜索它：

<div _ngcontent-c9="" class="tile-title" title="Pay">Pay </div>

但是我无法通过此CSS_SELECTOR找到它：

onWebView(allOf<View>(isDisplayed(), isJavascriptEnabled()))
                    .withElement(findElement(Locator.CSS_SELECTOR, "div[title=Pay]"))

类似地，我也尝试过使用X_PATH字符串，甚至还尝试使用类名（不是唯一的），但是仍然失败。

我们确实创建了多个Web视图，但是只有一个可见。

我该怎么做才能更清楚地说明为什么我不能选择有问题的div？

更新

看来我在日志中错过了一些揭示我部分问题的东西。我在日志中看到一个AmbiguousViewMatcherException。

看代码，我们有一个名为web_container的FrameLayout，并通过addView()调用将3个Webview附加到视图。因此，此组件最终有3个子代。

我将测试更改为使用withParent()和isDisplayed()来匹配网络视图。该调用之前曾引发异常，但现在通过了。

onWebView(allOf(withParent(withId(R.id.web_container)), isDisplayed())).forceJavascriptEnabled()

鉴于此成功，我仍然无法在此Webview中找到任何东西，这是修改后的onWebVeiw语句：

onWebView(allOf(withParent(withId(R.id.web_container)), isDisplayed())).forceJavascriptEnabled()

 Log.d("FeatureTest", "passed forceJavaScriptEnabled()")    
onWebView(allOf(withParent(withId(R.id.web_container)), isDisplayed()))
                        .withElement(findElement(Locator.CSS_SELECTOR, "div[title=Pay]")).perform(webClick())

我在日志中看到的错误：

Answer 1

您需要在第一次互动结束时致电Caused by: java.lang.IllegalArgumentException: JBAS011470: O unitName persistente não foi especificado e existem definições de unidade ...；

否则，您将无法访问（或匹配）该引用。

.reset()

作为Espresso Web的documentation：

onWebView(allOf<View>(isDisplayed(), isJavascriptEnabled())) .withElement(findElement(Locator.CSS_SELECTOR, "div[title=Pay]")) .perform( ... ) .reset();将WebView还原为其初始状态。当诸如单击之类的先前操作引入了导航更改从而使ElementReference和WindowReference对象不可访问时，这是必需的。

然后再次匹配，将提供一个新的引用，可以对其进行访问。

切换WebView后无法使用findElement
