Hi Michael,
Thanks for the code. I closely follow your seleniumconf and Google Tech Talk presentations. Your blog on setting up private instance was very useful.
Now that I tried to run this code. Everytime I get this error.
2223 performance log entries found
Exception in thread "main" org.json.JSONException: JSONObject["data"] not found.
at org.json.JSONObject.get(JSONObject.java:454)
Can you help me in this?
Praveen.
Hi Michael,
I resolved the above mentioned issue. It works like charm. Problem was with Location attribute in URL while creating the test. It was not able to find the location 'Test' in my private instance.
Praveen.
Hi Michael,
I posted a comment here yesterday but don't see it here now. So I'm re-posting.
I use Selenium WebDriver and write tests using Java code. I'd like to try out your test code, but I need more direction to make your example code work. Can you please write up a step-by-step tutorial on how to make your tests work? I'm anxious to try this out.
Thanks!
Seth
Hi,
Is this possible to replicate with C# bindings?
For starters, I can't find the equivalent of LoggingPreferences or driver.manage().logs().
HI,
I tried your demo code, but get the exception :
java.net.ConnectException: Connection refused
Could you please let me know if am missing anything.
THanks
Mugil
Hi Michael,
I was wondering about the Python code example you have above. When I run the example code to check the performance logs, it says that type does not exist? Do the performance logs need to be enabled in the webdriver? Just thought I'd get your two cents.
Thanks,
Ryan
@ryanarioli on line 9, try 'performance' instead of 'profiler'
desired_capabilities={'loggingPrefs': {'performance': 'INFO'}})
I watched your talk and was just wondering about the webpagetest.org part, I see you have implemented this to work giving results from that service, I would love to integrate these into our teamcity CI and not use werbpagetest. Instead just report through teamcity, what sort of CI have you been using and why did you choose to do it this way? Was it just so you could present data nicely? Thanks!
Thanks a lot for posting the code! This looks very promising for our needs of capturing performance baseline in feature tests.
I'm trying to make it work with a private instance of WebPagetest 2.13. I've setup the instance on a built-in Apache HTTP Server in OS X Mavericks and copied locations.ini.sample
to locations.ini
. The server renders the home page at http://localhost/index.php and I can see "WebPagetest.org - Dulles, VA" location.
When I try to submit performance logs to the server I'm getting:
org.json.JSONException: JSONObject["data"] not found.
at org.json.JSONObject.get(JSONObject.java:499)
at org.json.JSONObject.getJSONObject(JSONObject.java:593)
at com.nete.cukejvmrefapp.WebPageTest.writeMultipartContent(WebPageTest.java:96)
at com.nete.cukejvmrefapp.WebPageTest.postResult(WebPageTest.java:85)
at com.nete.cukejvmrefapp.WebPageTest.submitResult(WebPageTest.java:43)
[skipped]
I'll try to troubleshoot, but do you have any ideas about the cause in the meantime?
Just a side note, on a Mac, I had to add Options FollowSymLinks
in Apache config under <Directory "/[skipped]/webpagetest">
because I was getting the following error in Apache logs on all URLs under webpagetest/
:
[error] [client ::1] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden
OK, I debugged the problem. The exception in this case is misleading and is happening because WebPageTest
doesn't detect the case where server connection is OK, but test creation returns failure in JSON. I have a patch: replace line #53 (return new JSONObject(new JSONTokener(reader));
) with the following:
JSONObject result = new JSONObject(new JSONTokener(reader));
if (!result.has("data")) {
throw new IOException("WebPageTest test creation failed for location " + location + ": " + result);
}
return result;
Now you get much nicer error messages. For example:
java.io.IOException: WebPageTest test creation failed for location Test: {"statusCode":400,"statusTe
xt":"Error submitting url for testing"}
But there is still a problem, which puzzles me. "Test" location is recognized (otherwise the error message is telling about an invalid location), but is there something wrong with it? What am I missing?
On a side note, does anybody have experience in presenting this performance data in any tool other than WebpageTest? The talk mentioned other tools, but no specific examples were provided.
Web page test gives you an option to export the tool as a har (HTTP Archive) file . You can then use http://www.softwareishard.com/har/viewer/ to view the har file
Update 6/3/2014 (Issue Fixed): Issue appears to have resolved itself after moving to a more recent version of the WPT www. Now after submitting multiple test run results to WPT server, the results page is updated immediately and no longer waiting for tests to complete.
We got the code working on our private instance. Thanks a bunch Michael. One issue we are hitting is the following:
After submitting a result and viewing the result page e.g. http:///results.php?test=140603_66_G , it always shows the following until a timeout is hit after 5+ minutes,
Test is partially complete (1 of 1 tests).
This page will refresh as tests complete.
After the timeout is reached and the page refreshes we are able to see the summarized results with the table showing Load Time, First Byte etc. for the median run at the top of the page. My question, is there a way to notify the server that we are done submitting results and to go ahead completing the test run and compile the summary results?
Looking at the current code for workdone.php it looks like the following snippet might be what needs to be done but I’m not 100% sure. If anyone could offer any guidance it would be much appreciated
// do any post-processing when the full test is complete that doesn't rely on testinfo
if ($done) {
logTestMsg($id, "Test Complete");
// send an async request to the post-processing code so we don't block
SendAsyncRequest("/work/postprocess.php?test=$id");
}
How to convert the logs to HAR format? Is there any API java? I know that exists in php on the site WebPageTest, but i would like in java.
Thanks!
Is there any code in java that converts this log to HAR format?
How do these Network.responseReceived timing values relate to the timings you would see in Chrome Developer Tools or a WPT waterfall. e.g. TTFB, total request time, etc?
"timing":{
"connectEnd":10.477000032551587,"connectStart":9.941000025719404,
"dnsEnd":9.941000025719404,"dnsStart":9.901000070385635,
"proxyEnd":-1,"proxyStart":-1,
"receiveHeadersEnd":20.198000012896955,

"sendEnd":11.696000001393259,"sendStart":11.64400007110089,
"sslEnd":-1,"sslStart":-1
}
Do I need to calculate them based on the original Timeline.eventRecorded or Network.requestWillBeSent events for the matching GET request?
Never mind, this answers my question:

I am using the code in Test.java but when running this code, i am getting an exception:
org.openqa.selenium.WebDriverException: unknown error: log type 'performance' not found
Hi Anky1987,
Did you find any solution. I too am getting the same error?
Thanks
Puneesh
@klepikov is it possible to add the capability to an existing webdriver in the middle of a test? I'm trying to figure out how to log a specific page load, and not the whole workflow. (eg. we have to login to access our app, and i don't want to time the login, and landing page load).
The upload to a WebPagetest instance is somewhat easier now. You can do a post to /import.php and it will return a test ID. There is also a UI on /import.php for testing it out (post fields are the same as the form fields in the UI).
Issue "org.openqa.selenium.WebDriverException: unknown error: log type 'performance' not found" has been fixed refer this thread
https://code.google.com/p/selenium/issues/detail?id=8457#c10
Thanks for the post.. very valuable. I am getting one issue with the above code.
"unknown error: unhandled inspector error: {"code":-32601,"message":"'Timeline.start' wasn't found"}".
Any idea? thanks in advance.
@klepikov Could you please be so kind and provide demo example of submitting performance logs to WebPageTest in Python?
@klepikov: I run your code. Performance record type appears to only include network activity. I am more interested in client CPU activity. I tried to change code by adding adding/enabling timeline but still got only Network activity records.
Could you please suggest how to retrieve client CPU activity.
Map<String, Object> perfLogPrefs = new HashMap<String, Object>();
perfLogPrefs.put("traceCategories", "browser,devtools.timeline,devtools"); // comma-separated trace categories
perfLogPrefs.put("enableTimeline", true);
@klepikov: Could you please be so kind and provide demo example of submitting performance logs to WebPageTest in Python?
Could you please provide the demo example of submitting performance logs to WebPageTest using C# with Selenium?
Also is it possible to download the HAR file from WebPageTest using Logging API(REST call) with C#?
am trying to extract the browser console logs for my tests which are running on standalone-chrome-debug container on different server. I do not get the logs when in run on docker container.
However when i run the same test on my local machine with chrome driver, the logs are getting extracted as expected. Does any one has idea if we can extract the browser console logs for the test running on docker container.
Following way i am trying to achieve this.
logPrefs.enable(LogType.BROWSER, Level.ALL);
public LogEntries getBrowserConsoleLogs() {
return driver.manage().logs().get(LogType.BROWSER);
}```
Can someone help me understand in the WebPageTest what is the baseURL? and the location? because i get the below error while running
Exception in thread "main" org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1]

The other reason you would want a local instance even after you get past the chunked encoding issue, is you won't be able to post a result to any of the public webpagetest.org locations -- it only allows its test agents to do that:) In a private instance you just configure a location with no restrictions and post to it.
BTW I just realized -- revision 1 of this gist has WebPageTest.java that does a POST with Content-Length:) I did that for debugging, it also dumps out a file with the POST content.
