I have a job to check some 300 urls if they are loaded correctly. They are the production urls of a company. One of the checks that we have to do is to understand if any of the image or the text not loaded properly.
For the images not loaded usually we get a cross mark.. But since we want to automate this task, what is the piece of code or the debugging tool which can tell us that there is 'image not found' error in a particular url?
We are also checking for error like '404' and '5xx' HTTP errors. But hoping to get the error if we check the debugging window.
Let me know in case more information is required.
Thanks

I’m trying to generate a flowmap with Three.js: https://threejs.org/examples/#webgl_water_flowmap
I’ve used parts of the code source indicated here: https://github.com/mrdoob/three.js/blob/master/examples/webgl_water_flowmap.html but nothing appears on my page: https://flowmaptest-site.superhi.com/
I would be super grateful if someone could help me :slight_smile:
The browser console reveals some error messages:
THREE.Water: Required component THREE.Reflector not found.
THREE.Reflector is a dependency of THREE.Water. Without including it, the component won't work.
Besides, it seems certain textures can not be loaded from your host.
GET https://flowmaptest-site.superhi.com/textures/water/Water_1_M_Normal.jpg 404 (Not Found)
GET https://flowmaptest-site.superhi.com/textures/water/Water_2_M_Normal.jpg 404 (Not Found)
I have a Jmeter script for an application for which i get pop up error message intermittently. Where as in jmeter we only come to know that flow got terminated by some failure.But we wont come to know the occurrence of Error pop -up message.
My requirement is if we encounter pop up error i want to write to an external file saying that ,the current page got failed due to pop-up error message.
If we can write the error message it's really great. I'm as of now not getting idea to achieve this.
Please can anyone help me in this. or can provide any hint to do R&D.
Thankyou in advance.
Updated the question with screen shot of error message.
As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
Looking into your screenshot, it is a form of JavaScript popup, most likely window.alert so there is no way to detect it via JMeter.
You can add i.e. Response Assertion to your test in order to introduce some pass/fail criteria, i.e. if you were in the middle of some transaction when the error occurred it should not finish successfully resulting in missing expected entry in the web page (or database), so you can conditionally fail relevant sampler(s) in this case. See How to Use JMeter Assertions in Three Easy Steps to learn more about the concept.
Alternatively you can use WebDriver Sampler plugin which provides JMeter integration with Selenium browser automation framework which drives a real browser, so you will be able to capture this popups and record the page titles/take screenshots, check out IsAlertPresent() class for more information.
you must get this error response in your jmeter request response.simple answer.Have a regex to extract.
My goal: I'd like to use an image from commons.mediawiki.org within a MediaWiki installation.
First I was trying to debug my InstantCommons configuration: Referring to files on commons.mediawiki.org failed for some reason. After activating various debugging options I learned that though general image download succeeded some kind of thumbnail followup request issued by the MediaWiki installation failed, which resulted into an overall error from the ForeignAPIRepo-Module.
As I can not deal with this error right now I thought I'd try something else as some kind of fallback: Download the MediaWiki image by specifiying the image URL in the upload image web page. The idea is to let MediaWiki download the image and include this image as regular wiki content. This way I would require to add license details manually and add a few comments, but this would be better than having no image.
But trying this I strangely get an error: It says "Fehler beim Senden der Anfrage" which means "Error while sending the request". But the internal request seems succeed in the logs. Here is what MediaWiki was logging:
[fileupload] Temporary file created "/tmp/URLdafce5345aa3-1"
[fileupload] Starting download from "https://upload.wikimedia.org/wikipedia/commons/c/c7/Broccoli%2C_Champignons%2C_Karotten_%2810581663524%29.jpg" <followRedirects>
[fileupload] <Error, collected 1 error(s) on the way, integer value set>
+------+---------------------------+------------------------------------------+
| 1 | http-request-error | |
+------+---------------------------+------------------------------------------+
[fileupload] Download by URL completed with HTTP status 200
Comment: All other log messages do not indicate anything that looks like an error or is related to the task of downloading the image, so I skipped them here.
The URL is correct, the image can be downloaded from the URL, MediaWiki receives a response code of 200, but instead of processing the response it indicates an error. Why? For http and https URLs I get the same result in the log.
Has anybody encountered this problem before in MediaWiki installations? Does anyone have any idea what the reason for this behaviour could be?
Comment: The wiki is of version 1.25.2 and a standard installation including SWM on an up to date standard Ubuntu Linux OS. Nothing exotic, nothing modified in any way.
Comment: Yes, I could upgrade to the latest version but, I'm not sure if this really solves the problem: I know that this featured did work in some other MediaWiki installations I have set up some time ago. Does anyone have a clue why this feature could fail here? Has anyone encountered something like this before?
Edit: I experimented with downloading from another MediaWiki instance of exactly the same version - 1.25.2 - in my local network. This did not succeed as well. But I get a different error message (translated): "The file .... could not be stored at ...". The "funny part": Though the error message indicated otherwise the file has been downloaded successfully and stored as expected. It has the correct user rights as one would expect, but log messages indicate that there are bugs in MediaWiki regarding this part: ("PHP Notice: Undefined property: UploadFromUrl::$nbytes") Maybe the uploading implementation is buggy somehow and the problems I am running into are typical?
There are multiple bugs with HTTPS support in MediaWiki, php-curl etc. See https://www.mediawiki.org/wiki/InstantCommons#HTTPS for debugging information, there is no magic bullet.
This is an example for an image that I add to the image_urls field.

Yet I get this warning and the image is not uploaded.
[zara_com] WARNING: File (code: 404): Error downloading image from http://static.zara.net/photos//2014/I/0/2/p/5875/309/800/2/w/1920/5875309800_1_1_1.jpg> referred in
Though an image like this one:
http://static.zara.net/photos//2014/V/1/3/p/1280/303/105/2/w/1920/1280303105_2_1_1.jpg
is uploaded normally.
What might be the problem? what should I check?
As far as I can see, they seem to be filtering requests made with the default scrapy user agent:
'User-Agent': 'Scrapy/0.24.2 (+http://scrapy.org)'
When I changed the USER_AGENT setting in settings.py of my project, it started returning 200 on all requests. The strange thing is that before that it returned 404 even on the image, which you said is returned normally.
P.S. It's not very good to scrape content from a site, if they are not allowing it, but well it's not like they are disallowing it in their robots.txt. Still you should probably enable the RobotsTxtMiddleware and the AutoThrottle extension to ensure you are playing fairly.
I'm using ABCPdf to convert HTML to a PDF. I'm using the method:
AddImageUrl()
This works fine in Dev and UAT, but on Production I continuously get the message:
Unable to render HTML. Unable to load
page
Anyone see this before? Need more info?

I guess you are tying to do URL->pdf generation. It is difficult to directly to do URL->pdf conversion. We ended up URL-Save HTML in local folder ->read HTML and convert to PDF-> delete HTML file from folder - tricky approach but it works. The only flaw is that you need to give read/write permission on a folder on server. Its still better than decreasing security settings.
have you take a look at this http://www.itjungles.com/dotnet/abc2pdf-unable-to-render-html
The default timeout for abcpdf is 15 seconds. If the page is taking longer than 15 seconds, you will get this exception.
Add the line below just after object creation of the document to resolve the issue.
theDoc.XHtmlOptions.Timeout = 10000000;
I found by working backwards (removing elements) from a target html page that omitting the tag (of all things) created this error. also, calling localhost in the target url generated this error.
I have no idea what caused this error, but I stopped the scheduled task that was running, then restarted it and it's worked fnie ever since.
