I have an android SDK and upon pressing a button opens a Webview where i can see a button whose html view is as below: <button type="button" class="button js-analytics-submit" id="submit-try-sample" data-analytics-category="Sample" data-analytics-label="Intro"> <svg xmlns="http://www.w3.org/2000/svg" width="58" height="58" viewBox="0 0 58 58" id="button-logo " class="button__logo"> <path fill="currentColor" fill-rule="evenodd" d="M37.32 21.933l2.877-2.876-.626-.625c-5.04-5.043-13.247-5.043-18.29 0-4.832 4.833-5.03 12.568-.6 17.643l-2.876 2.875.625.625c5.042 5.043 13.247 5.043 18.29 0 4.832-4.832 5.03-12.567.6-17.642zm-14.79-2.25c4.144-4.144 10.76-4.344 15.142-.6l-1.64 1.64c-3.488-2.86-8.644-2.664-11.9.593-3.256 3.256-3.454 8.412-.594 11.9l-1.608 1.608c-3.743-4.382-3.542-11 .6-15.142zm12.94 18.642c-4.143 4.144-10.76 4.344-15.142.6l1.64-1.64c3.488 2.86 8.644 2.664 11.9-.593 3.256-3.256 3.454-8.412.594-11.9l1.608-1.608c3.743 4.382 3.543 10.998-.6 15.14z"></path> </svg> <span class="button__wrapper" id="button-text"> <span class="button__text"> Let’s do this! </span> </span> </button> Now i'm trying to press/click a button using the following but nothing works :( onWebView().perform(script("return document.getElementById(\"submit-try-sample\").click()")); onWebView().withElement(findElement(Locator.ID, "submit-try-sample")).perform(webClick()); onWebView().withElement(findElement(Locator.XPATH, "//button//span[contains(text(),'do this')]")).perform(webClick()); The above code doesn't throw any error and executes successfully but it doesn't click the button. Would appreciate if any espresso Webview expert can help me with clicking the button please. Thanks

A bit hard to know whats going on? Can you provide a logcat or better yet a small small which we can use to reproduce the issue? 

do you have more than 1 webview in your activity? maybe you need onWebView(withId...)?

Hi Nick / Luis,

Thanks for replying!

I've tried following statement as well but it fails with an exception mentioned the logcat details

onWebView(withId(R.id.__sample_web_view)).forceJavascriptEnabled().withElement(findElement(Locator.ID, "submit-try-sample")).perform(webClick());

Logcat as follows:

The above code doesn't throw any error and executes successfully but it doesn't click the button.

I would try specifying the web view ID and forcing javascript: onWebView(withId(R.id.web_view)).forceJavascript().withElement(...)

Hi Nick / Luis,

Thanks for replying!

I've tried following statement as well but it fails with an exception mentioned the logcat details

onWebView(withId(R.id.__sample_web_view)).forceJavascriptEnabled().withElement(findElement(Locator.ID, "submit-try-sample")).perform(webClick());

I would try to boil your sample webview to the most minimal thing and build it back up to see what works. I've only done clicks on links so maybe try that first? Like

<a href="someplace.com" id="some-id">Click Me!</a>

It's also possible this is not working simply because the instrumentation is buggy. We experienced a case where matching the text of a given <style> block was failing because the instrumentation thought there was no text in the block even though it definitely was there.

Hi Luis,

I did not quite understand the first part. However i'm observing the same error as mentioned at https://github.com/googlesamples/android-testing/issues/61

Any help would be really appreciated

Hi Nick/Luis,

t executes the following line and proceed further but it doesn't click the button in real. I tried debugging and i'm attaching the screenshot of it. Please let me know if you can figure out anything from it. It just says Status : 0 value :null.

 

Logcat info for the same as follows:

07-17 07:06:29.395 7090-7090/com.sample.android.sdk.sample I/ViewInteraction: Performing 'Evaluate Atom: android.support.test.espresso.web.model.TransformingAtom@132cfdd in window: null with element: null' action on view WebView with JS enabled

07-17 07:06:29.445 7090-7090/com.sample.android.sdk.sample I/ViewInteraction: Performing 'Evaluate Atom: android.support.test.espresso.web.webdriver.DriverAtoms$1@6984a23 in window: null with element: {"ELEMENT":":wdc:1468753140041"}' action on view WebView with JS enabled

It says window as null but it has a reference to element. 

I'm really stuck at this. Not sure whether its a bug. Can someone help?

​

Thanks

What I meant was to boil down your sample to something ultra-simple to see if it works, then gradually add back things until it breaks again to determine the cause of the problem.

So, for example, your example HTML:

<button type="button" class="button js-analytics-submit" id="submit-try-sample" data-analytics-category="Sample" data-analytics-label="Intro">
  <svg xmlns="http://www.w3.org/2000/svg" width="58" height="58" viewBox="0 0 58 58" id="button-logo
" class="button__logo">

</svg>
  <span class="button__wrapper" id="button-text">
    <span class="button__text">
      Let’s do this!
    </span>
  </span>
</button>

Replace all of that with:

<a href="google.com" id="anchor">Link!</a>

Can't get simpler than that. Then try clicking that link through Espresso. If that works, replace <a> with <button>. If that works, add the "class" attribute. If that works ... etc, etc. until you find the one change that makes it fail.

Thanks Luis for all you support.

Finally figured out the culprit. While debugging further i got to know 'touchstart' was the causing the issue. My submitEventType was set to 'touchstart' but when i set it to 'click', my statement started working. Took couple of days to figure out. Sigh!

Learned something new. Shall i raise this as a bug or new request? What do you guys think?

Thanks,

Ketan

Thanks Ketan for your post which saves my time.
I met the exact same webclick problem during testing. Is there any plan to support it?
