问题

我用espresso测试webview的发生了异常,在web页面a,执行了点击,页面跳转到web页面b后,再尝试点击就失败了,大家有遇到吗?

测试代码

@Rule
public ActivityTestRule<Activity> mActivityRule = new ActivityTestRule<Activity>(
        Activity.class, false, false) {
    @Override
    protected void afterActivityLaunched() {
        // Technically we do not need to do this - WebViewActivity has javascript turned on.
        // Other WebViews in your app may have javascript turned off, however since the only way
        // to automate WebViews is through javascript, it must be enabled.
        onWebView().forceJavascriptEnabled();
    }
};

@Test
public void webviewTest() throws Exception {

    Thread.sleep(60000);
    long start = System.currentTimeMillis();
    mActivityRule.getActivity();
    onIdle();

    long end = System.currentTimeMillis();
    System.out.println("wait for idle:" + (end - start));

    //点击web页面a上的菜单
    onWebView()
            .withElement(findElement(Locator.XPATH, "(//*[@class='ng-binding'])[3]"))
            .perform(webClick());

    onIdle();

    //点击web页面b上的菜单
    onWebView()
            .withElement(findElement(Locator.XPATH, "(//*[@class='ng-binding'])[3]"))
            .perform(webClick());
