I am trying to access a website that requires a login thru an alert box such as the one below:
I have tried to look up many different ways to do this and they dont seem to work. what i have tried are listed below:
Didnt work and gave me the same login alert.
start_url = 'http://username:password#example.com'
agent.get(start_url)
Keep getting an error message saying "NoAlertPresentException: Message: no alert open"
start_url = 'http://www.example.com'
alert = agent.switch_to_alert()
alert.send_keys("username")
alert.send_keys("password")
Get an error saying webdriver has no attribute "switchTo"
start_url = 'http://www.example.com'
agent.switchTo().alert().sendKeys("username")
I have to use Chrome because of the versions of IE and Firefox I have and can get, do not support the functions in the site
I have been having this exact same issue for some time now - with my end goal being to do this headless (in the background without visually launching an instance of Chromedriver).
Non-Ideal Solution 1:
I first used a library called pynput to automatically type the credentials in to the alert box and click the ok button, it was pretty simple to get working but:
still didn't work headlessly
I had to be focused on the browser or it would type the credentials elsewhere
This worked great in the meantime as everywhere I looked online it seemed like there was nothing I could do to overcome authentication alerts headlessly...
I'm a relative beginner (started programming <1 year ago) so perhaps I just wasn't looking in the right places!
I've now solved this issue though like so:
First I logged in to the alert as normal on Chrome while monitoring the Network section of devtools to get a good look at the GET request for the protected page screencap here:
Upon seeing that the Authorization was Basic (this will work for Bearer too) I tested just copying the same request in Postman with this header and it worked! Now if only there was a way to make http requests from Selenium???
I first tried the library selenium-requests (which didn't work for me: I got the same error as this person https://github.com/cryzed/Selenium-Requests/issues/33
This library seems absolutely excellent and exactly what I needed, I just don't currently have the know-how to get past firewalls/whatever was stopping me at this stage...
What eventually worked for me was the library selenium-wire. I followed this guide https://pypi.org/project/selenium-wire/#intercepting-requests-and-responses to have the webdriver navigate to the protected page as normal, but intercept the request and add the Authorization header before sending it :) now this works for me totally headlessly. Granted, this won't work on more secure websites but I hope it helps someone having the same issue.
This is Pythoncode
Problem with alert boxes (especially sweet-alerts is that they have a
delay and Selenium is pretty much too fast)
An Option that worked for me is: (just exchange the button click in the end with whatever action you want to have)
while True:
try:
driver.find_element_by_xpath('//div[#class="sweet-alert showSweetAlert visible"]')
break
except:
wait = WebDriverWait(driver, 1000)
confirm_button = driver.find_element_by_xpath('//button[#class="confirm"]')
confirm_button.click()
Note to 2: Here is probably the error due to the alert taking more time to load than the single elements (such as username, etc.)
Note to 3.: I think it should be switch_to

I was having some trouble seeing teammates' Code Review Requests in TFS and was poking around with stuff I don't know that much about. All of a sudden, now, whenever I attempt to run a unit test in debug mode, I get a Save Query As popup with the referenced message. I don't want this. There are Save and Cancel options, and if I cancel, I am able to continue with the test. Any clue what setting I hit (perhaps in My Work) that started this behavior?
While im trying to save changes to HTML Form Web Part message appears "cannot retrieve properties at this time" and "cannot save changes" right after it. I've searched internet ... but there is no real solution.
So, what i've got :
Sharepoint 2013 foundation, latest updates ( RU )
No errors in events, nothing special in ULS ( except annoying "Forced due to logging gap", dont know what to do with this btw))
In IIS all bindings added, all AAM paths are right ( i hope they are right, but everything else is working just fine )
There is enough ram/hdd on server
At first time all worked ( nothing very special was done with SP after that )
Same error on different browsers ( IE/FF/CH ), on different PC including server itself
Master pages are in their original state
IIS reset, recycle, mumbo-jumbo, blob cache cleaning
No matter on what web page or in any other place ( like adding it into list view page ), on root and sub-sites, with any possible urls ( intranet, internet, deep space or whatever possible url ). Also have tried in another site collection ( create new ), even in administration page ( Distribution groups page can be edited for some reason ).
Well, it could be a solution to just destroy SP in some horrible way, but its our production server ... on test server everything is fine of course.
In Fiddler i've catched next SOAP responce error :
---soap:ServerException of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.-Error occurred.
Very informative message "error occurred", well, NOW we know it was error :)
Its responce from /_vti_bin/WebPartPages.asmx
Adding debug options to web.config in sts or vti_bin gives nothing, no log created and no additional information on exception.
From that point i really don't know what to do ...
Hope for Your help :)
Thanks))
Ran into this same issue myself, after searching everywhere I found that if I use IE I have to use the developer tools, hit F12 and select version 8 in the upper right corner of the developer tool window, once that was done I was able to make and save the changes and they still worked when I changed my browser setting back to version 10, apparently there is a bug in the newer versions of IE that cause issues like these.
I am developing an application using Django that works similar to a project manager. For this reason, the system should be capable of storing information about everything. When I say everything I refer to the actions the users do, the errors that occurred while doing an action, etc.
I have a class Log and one of its attributes is called action_type, this attribute specifies what kind of action just happened. I am supposed to have 5 kinds of types:
INFO: this log stores the information related to user's actions such as creating a project, create other users, etc.
DEBUG: should store comments made by the developers that will allow them to detect errors.
ERROR: shows errors that occurred in the system but they don't affect the system's functionality.
WARNING: it's for potentially damaging actions.
FATAL: unexpected errors, exceptions and security breaches.
I can only come up with logical logs for INFO.
Could you tell me some reasonable logs that I should include in this and the other categories?
The answer will depend greatly on exactly what your application does, but my basic approach is this:
Each time you get ready to log an event, just think about the event and it will be clear where it belongs. Did it kill your application? It's fatal. Did it prevent something from working correctly? It's an error. Could it prevent something from working, and did we just get lucky this time? It's a warning. Does anyone care? Info. Otherwise, if you still need to log it, it must be for debugging purposes.
In your particular context, it sounds like you might only be trying to log user actions. If that is the case, the only actions that could be fatal would be ones for which you don't provide an undo option (or, I suppose, if the user is able to order a piano bench and a length of strong rope through your application). I also couldn't really imagine any debug-level logs coming from user actions. Because of this, I assume you will be logging code level events in addition to user actions.
FATAL: This should only appear in the logs when your application actually crashes, and possibly alongside 500 responses. You might generate these within your wsgi application in a catch-all, only when the process would otherwise have died.
ERROR: Likely tied to http error responses. This is typically for errors caused by something outside your application. Things that happen in your code are probably expected and <= warning level, or unexpected and fatal. Errors might be a 404 from the user making a typo in a url, validation errors on form submission, or authentication errors. From the other direction, errors might be returned from remote web services that you contact or IO errors from the os.
WARNING: For things that don't break anything, but that might bite you if you keep it up. Examples are using deprecated apis and anywhere something only worked because of the default (time zone, character encoding, etc). Maybe certain input values result in warnings, too, like setting a due date in the past.
INFO: General, healthy operation. Someone created a database row (a new project or a task?), created an account, logged in or out, a socket was successfully opened, etc.
DEBUG: Just what it says. Output that you will usually turn off once the code is working correctly. Method entry/exit, object instantiation, field values at various points in the code, counters. Whatever you need to figure out why your program is crashing right now, as you work on it.
I'm trying to test the happy-path for a piece of code which takes a long time to respond, and then begins writing a file to the response output stream, which prompts a download dialog in browsers.
The problem is that this process has failed in the past, throwing an exception after this long amount of work. Is there a way in selenium to wait-for-download or equivalent?
I could throw in a Thread.sleep, but that would be inaccurate and unnecessarily slow down the test run.
What should I do, here?
I had the same problem. I invented something to solve the problem. A tempt file is created by Python with '.part' extension. So, if still we have the temp, python can wait for 10 second and check again if the file is downloaded or not yet.
while True:
if os.path.isfile('ts.csv.part'):
sleep(10)
elif os.path.isfile('ts.csv'):
break
else:
sleep(10)
driver.close()
So you have two problems here:
You need to cause the browser to download the file
You need to measure when the downloaded file is complete
Neither problemc an be directly solved by Selenium (yet - 2.0 may help), but both are solvable problems. The first problem can be solved by GUI automation toolkits, such as AutoIT. But they can also be solved by simply sending an automated keypress at the OS level that simulates the enter key (works for Firefox, a little harder on some versions of Chrome and Safari). If you're using Java, you can use Robot to do that. Other languages have similar toolkits to do such a thing.
The second issue is probably best solved with some sort of proxy solution. For example, if your browser was configured to go through a proxy and that proxy had an API, you could query the proxy with that API to ask when network activity had ended.
That's what we do at http://browsermob.com, which is a a startup I founded that uses Selenium to do load testing. We've released some of the proxy code as open source, available at http://browsermob.com/tools.
But two problems still persist:
You need to configure the browser to use the proxy. In Selenium 2 this is easier, but it's possible to do it with Selenium 1 as well. The key is just making sure that your browser launcher brings up the browser with the right profile/settings.
There currently is no API for BrowserMob proxy to tell you when network traffic has stopped! This is a big hole in the concept of the project that I want to fix as soon as I get the time. However, if you're keen to help out, join the Google Group and I can definitely point you in the right direction.
Hope that helps you identify your various options. Best of luck!
This is Chrome-testing-only solution for controlling the downloads with javascript..
Using WebDriver (Selenium2) it can be done within Chrome's chrome:// which is HTML/CSS/Javascript:
driver.get( "chrome://downloads/" );
waitElement( By.CssSelector("#downloads-summary-text") );
// next javascript snippet cancels the last/current download
// if your test ends in file attachment downloading
// you'll very likely need this if you more re-instantiated tests left
((JavascriptExecutor)driver).executeScript("downloads.downloads_[0].cancel_();");
There are other Download.prototype.functions in "chrome://downloads/downloads.js"
This suites you if you just need to test some info note eg. caused by file attachment starting activity, and not the file itself.
Naturally you need to control step 1. - mentioned by Patrick above - and by this you control step 2. FOR THE TEST, not for the functionality of actual file download completion / cancel.
See also : Javascript: Cancel/Stop Image Requests which is relating to Browser stopping.
This falls under the "things that can't be automated" category. Selenium is built with JavaScipt and due to JavaScript sandbox restrictions it can't access downloads.
Selenium 2 might be able to do this once Alerts/Prompts have been implemented but that this won't happen for the next little while yet.
If you want to check for the download dialog, try with AutoIt. I use that for uploading and downloading the files. Using AutoIt with Se RC is easier.
def file_downloaded?(file)
while File.file?(file) == false
p "File downloading in progress..."
sleep 1
end
end

Trying to honor a feature request from our customers, I'd like that my application, when Internet is available, check on our website if a new version is available.
The problem is that I have no idea about what have to be done on the server side.
I can imagine that my application (developped in C++ using Qt) has to send a request (HTTP ?) to the server, but what is going to respond to this request ? In order to go through firewalls, I guess I'll have to use port 80 ? Is this correct ?
Or, for such a feature, do I have to ask our network admin to open a specific port number through which I'll communicate ?
#pilif : thanks for your detailed answer. There is still something which is unclear for me :
like
http://www.example.com/update?version=1.2.4
Then you can return what ever you want, probably also the download-URL of the installer of the new version.
How do I return something ? Will it be a php or asp page (I know nothing about PHP nor ASP, I have to confess) ? How can I decode the ?version=1.2.4 part in order to return something accordingly ?
I would absolutely recommend to just do a plain HTTP request to your website. Everything else is bound to fail.
I'd make a HTTP GET request to a certain page on your site containing the version of the local application.
like
http://www.example.com/update?version=1.2.4
Then you can return what ever you want, probably also the download-URL of the installer of the new version.
Why not just put a static file with the latest version to the server and let the client decide? Because you may want (or need) to have control over the process. Maybe 1.2 won't be compatible with the server in the future, so you want the server to force the update to 1.3, but the update from 1.2.4 to 1.2.6 could be uncritical, so you might want to present the client with an optional update.
Or you want to have a breakdown over the installed base.
Or whatever. Usually, I've learned it's best to keep as much intelligence on the server, because the server is what you have ultimate control over.
Speaking here with a bit of experience in the field, here's a small preview of what can (and will - trust me) go wrong:
Your Application will be prevented from making HTTP-Requests by the various Personal Firewall applications out there.
A considerable percentage of users won't have the needed permissions to actually get the update process going.
Even if your users have allowed the old version past their personal firewall, said tool will complain because the .EXE has changed and will recommend the user not to allow the new exe to connect (users usually comply with the wishes of their security tool here).
In managed environments, you'll be shot and hanged (not necessarily in that order) for loading executable content from the web and then actually executing it.
So to keep the damage as low as possible,
fail silently when you can't connect to the update server
before updating, make sure that you have write-permission to the install directory and warn the user if you do not, or just don't update at all.
Provide a way for administrators to turn the auto-update off.
It's no fun to do what you are about to do - especially when you deal with non technically inclined users as I had to numerous times.
Pilif answer was good, and I have lots of experience with this too, but I'd like to add something more:
Remember that if you start yourapp.exe, then the "updater" will try to overwrite yourapp.exe with the newest version. Depending upon your operating system and programming environment (you've mentioned C++/QT, I have no experience with those), you will not be able to overwrite yourapp.exe because it will be in use.
What I have done is create a launcher. I have a MyAppLauncher.exe that uses a config file (xml, very simple) to launch the "real exe". Should a new version exist, the Launcher can update the "real exe" because it's not in use, and then relaunch the new version.
Just keep that in mind and you'll be safe.
Martin,
you are absolutely right of course. But I would deliver the launcher with the installer. Or just download the installer, launch it and quit myself as soon as possible. The reason is bugs in the launcher. You would never, ever, want to be dependent on a component you cannot update (or forget to include in the initial drop).
So the payload I distribute with the updating process of my application is just the standard installer, but devoid of any significant UI. Once the client has checked that the installer has a chance of running successfully and once it has downloaded the updater, it runs that and quits itself.
The updater than runs, installs its payload into the original installation directory and restarts the (hopefully updated) application.
Still: The process is hairy and you better think twice before implementing an Auto Update functionality on the Windows Platform when your application has a wide focus of usage.
in php, the thing is easy:
<?php
if (version_compare($_GET['version'], "1.4.0") < 0){
echo "http://www.example.com/update.exe";
}else{
echo "no update";
}
?>
if course you could extend this so the currently available version isn't hard-coded inside the script, but this is just about illustrating the point.
In your application you would have this pseudo code:
result = makeHTTPRequest("http://www.example.com/update?version=" + getExeVersion());
if result != "no update" then
updater = downloadUpdater(result);
ShellExecute(updater);
ExitApplication;
end;
Feel free to extend the "protocol" by specifying something the PHP script could return to tell the client whether it's an important, mandatory update or not.
Or you can add some text to display to the user - maybe containing some information about what's changed.
Your possibilities are quite limitless.
My Qt app just uses QHttp to read tiny XML file off my website that contains the latest version number. If this is greater than the current version number it gives the option to go to the download page. Very simple. Works fine.
I would agree with #Martin and #Pilif's answer, but add;
Consider allowing your end-users to decide if they want to actually install the update there and then, or delay the installation of the update until they've finished using the program.
I don't know the purpose/function of your app but many applications are launched when the user needs to do something specific there and then - nothing more annoying than launching an app and then being told it's found a new version, and you having to wait for it to download, shut down the app and relaunch itself. If your program has other resources that might be updated (reference files, databases etc) the problem gets worse.
We had an EPOS system running in about 400 shops, and initially we thought it would be great to have the program spot updates and download them (using a file containing a version number very similar to the suggestions you have above)... great idea. Until all of the shops started up their systems at around the same time (8:45-8:50am), and our server was hit serving a 20+Mb download to 400 remote servers, which would then update the local software and cause a restart. Chaos - with nobody able to trade for about 10 minutes.
Needless to say that this caused us to subsequently turn off the 'check for updates' feature and redesign it to allow the shops to 'delay' the update until later in the day. :-)
EDIT: And if anyone from ADOBE is reading - for god's sake why does the damn acrobat reader insist on trying to download updates and crap when I just want to fire-it-up to read a document? Isn't it slow enough at starting, and bloated enough, as it is, without wasting a further 20-30 seconds of my life looking for updates every time I want to read a PDF?
DONT THEY USE THEIR OWN SOFTWARE??!!! :-)
On the server you could just have a simple file "latestversion.txt" which contains the version number (and maybe download URL) of the latest version. The client then just needs to read this file using a simple HTTP request (yes, to port 80) to retrieve http://your.web.site/latestversion.txt, which you can then parse to get the version number. This way you don't need any fancy server code --- you just need to add a simple file to your existing website.
if you keep your files in the update directory on example.com, this PHP script should download them for you given the request previously mentioned. (your update would be yourprogram.1.2.4.exe
$version = $_GET['version'];
$filename = "yourprogram" . $version . ".exe";
$filesize = filesize($filename);
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: post-check=0, pre-check=0");
header("Content-type: application-download");
header('Content-Length: ' . $filesize);
header('Content-Disposition: attachment; filename="' . basename($filename).'"');
header("Content-Transfer-Encoding: binary");
This makes your web browser think it's downloading an application.
The simplest way to make this happen is to fire an HTTP request using a library like libcurl and make it download an ini or xml file which contains the online version and where a new version would be available online.
After parsing the xml file you can determine if a new version is needed and download the new version with libcurl and install it.
Just put an (XML) file on your server with the version number of the latest version, and a URL to the download the new version from. Your application can then request the XML file, look if the version differs from its own, and take action accordingly.
I think that simple XML file on the server would be sufficient for version checking only purposes.
You would need then only an ftp account on your server and build system that is able to send a file via ftp after it has built a new version. That build system could even put installation files/zip on your website directly!
If you want to keep it really basic, simply upload a version.txt to a webserver, that contains an integer version number. Download that check against the latest version.txt you downloaded and then just download the msi or setup package and run it.
More advanced versions would be to use rss, xml or similar. It would be best to use a third-party library to parse the rss and you could include information that is displayed to your user about changes if you wish to do so.
Basically you just need simple download functionality.
Both these solutions will only require you to access port 80 outgoing from the client side. This should normally not require any changes to firewalls or networking (on the client side) and you simply need to have a internet facing web server (web hosting, colocation or your own server - all would work here).
There are a couple of commercial auto-update solutions available. I'll leave the recommendations for those to others answerers, because I only have experience on the .net side with Click-Once and Updater Application Block (the latter is not continued any more).
