Espresso intent test failing
<p>I'm learning android instrumentation testing with espresso. I have an app which has a drawer menu and there is a menu called About. I was testing click on that menu item and contents of activity. </p>

<p>testfunction:</p>

<pre><code>  @Test
public void testNavigationDrawerAboutMenu() {
    onView(withId(R.id.drawer_layout))
            .perform(DrawerActions.open()); //open drawer
    onView(withText("About")).perform(click());
    onView(withId(R.id.aboutsptemail)).check(matches(withText(R.string.screen_about_support_email)));
    onView(withId(R.id.aboutcpright)).check(matches(isDisplayed()));
    onView(withId(R.id.aboutprivacy)).check(matches(isDisplayed()));
    onView(withId(R.id.abouttermsconditions)).check(matches(isDisplayed()));
    onView(withId(R.id.aboutsptemail)).perform(click());
}
</code></pre>

<p>now the last textview has weblink embedded in it. so when you click on it, it opens the link(www.support.com) in  a web view within the app. I want to test this functionality. so I tried this:</p>

<pre><code>intended(hasComponent(WebViewActivity.class.getName())); //check if webview called on supportEmail link click
</code></pre>

<p>but test fails with this error trace: </p>

<p>I have also tried resolve by idling the resources before checking for intent. But didn't work. Can anybody help?</p>
