appium ios python "an error occured while executing user supplied javascript" - python

I'm using a bit Appium (v1.3.7) to make nice tests! And I'm trying to have tests that runs on both Android and iOS. I'm testing directly on the phones not on simulators and using python to write tests.
I got a test to test if an ad banner is displayed and if I can click on it.
Simple enough on Android I open the application and navigate to the right place, then send a press event and assert that the elements of my application are no longer visible (since now we have the phone store openned at "download application" or something similar)
It's 2 lines:
e1 = TouchAction(self.webdriver)
e1.press(x=300, y=1200).release().perform()
It's working on Android, but on iOS it returns the exception : "an error occured while executing user supplied javascript" whenever I call the perform action.
All of this is done in a native application if it can help. The rest of appium is working fine I can move into my application and all but since here my ads can be pretty random I only had the "press where the ad should be" solution.
Also fruitsrap keep failing whenever I launch a test. Might be linked even if I found out that it should not be used anymore (https://github.com/appium/appium/issues/4501)
Do anyone knows what's happening in there?

Figured what was wrong, the x and y positions were out of bound, the screen resolution of the phone was smaller than I thought.
It's working properly with in bound values. But the error message should be more explicit :)

Why does the Google Calendar Quickstart for Python give me an OSError (WinError 10013) (access socket in a way forbidden)

I followed Google's Quickstart for Python, step-by-step. I followed each step exactly, often copying and pasting. I definitely have the Google Calendar API enabled. I've installed the Google Client Library with Pip. I've set up the sample code and the credentials.json in its own folder. So, why am I getting this error when I run it:
"OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions"
To figure this out, I've learned what a socket is. (It's literally the combination of an IP address and a single port). I've learned how to use netstat, though I don't know yet how this applies to what I'm doing. I've looked into using ShellExecuteEx based on an answer in this question, but I don't know how to use that with Python.
I've tried adding the script from the accepted answer to this question (which actually uses the ShellExecuteEx method though I don't notice this) into an admin.py file and import this admin.py script into quickstart.py. After updating the admin.py script to Python 3 syntax and running quickstart.py, Windows 8.1 asks me if I will allow access. I say yes, and it still gives me the OSError (WinError 10013) on accessing the socket in a forbidden way. The UAC is not the issue.
I suspect it's a port conflict, where something's already using the port that the script that Google's trying to use. But I'm worried that the port is decided by a black box function that I won't be able to change. The error itself doesn't say which port it's using, so I'll need to do more research.
It is a port issue.
Go to line 34 on the quickstart.py file (or where it says creds =
run_local_server()).
Go to the flow.py file in the
google_auth_oauthlib package with this function (in VS Code, click
run_local_server() and press F12 or right click and select "Go to
Definition").
You'll see line 369 (at the time of this writing) say self, host='localhost', port=8080,.
When I look at netstat, it actually says this port is in use, probably with an Apache server I never turned off.
Change the value in the flow.py file in the google_auth_oauthlib package to 8090, so 369 looks like self, host='localhost', port=8090,.
I ran the quickstart.py script again, and the window to authenticate my Google account popped up.
I selected my account, and it worked. No messing with the admin stuff.
I'm glad I was able to find it like this because I thought the port was selected in some black box manner, like it was decided from a server at Google.

Workaround for Python & Selenium: authenticate against Active Directory

I am using Python (2.7) and Selenium (3.4.3) to drive Firefox (52.2.0 ESR) via geckodriver (0.19.0) to automate a process on a CentOS 7 machine.
I need totally unattended operation of this automation with user credentials passed through; no storage allowed and no breaking in.
One piece of drama is being caused by the fact that the internal website required for the process is within an Active Directory domain while the machine running my automation is not. I have no need to validate the user, only pass the credentials to the website in such a way as to not require human interaction or for the person to be a local user on the machine.
I have tried various permutations of:
[protocol]://[user,pass]#[url]
driver.switch_to_alert() + send_keys
It seems some of those only work on IE, something I have no access to.
I have checked for libraries to handle this and all to no avail.
I can add libraries to python and I have sudo access to the machine - can't touch authentication, so AD integration is not possible.
How can I give this AD website the credentials of an arbitrary user such that no local storage of their credentials happens an no user interaction is required?
Thank you
EDIT
I think something like a proxy which could authenticate the user then retain that authentication for selenium to do its thing ...
Is there a simple LDAP/AD proxy available?
EDIT 2
Perhaps a very simple way of stating this is that I want to pass user credentials and prevent the authentication popup from happening.
Solution Found:
I needed to use a browser extension.
My solution has been built for chromium but it should port almost-unchanged for Firefox and maybe edge.
First up, you need 2 APIs to be available for your browser:
webRequest.onAuthRequired - Chrome & Firefox
runtime.nativeMessaging - Chrome & Firefox
While both browser APIs are very similar, they do have some significant differences - such as Chrome's implementation lacking Promises.
If you setup your Native Messaging Host to send a properly-formed JSON string, you need only poll it once. This means you can use a single call to runtime.sendNativeMessage() and be assured that your credentials are paresable. Pun intended.
Next, we need to look at how we're supposed to handle the webRequest.onAuthRequired event.
Since I'm working in Chromium, I need to use the promise-less Chrome API.
chrome.webRequest.onAuthRequired.addListener(
callbackFunctionHere,
{urls:[targetUrls]},
['asyncBlocking'] // --> this line is important, too. Very.
The Change:
I'll be calling my function provideCredentials because I'm a big stealy-stealer and used an example from this source. Look for the asynchronous version.
The example code fetches the credentials from storage.local ...
chrome.storage.local.get(null, gotCredentials);
We don't want that. Nope.
We want to get the credentials from a single call to sendNativeMessage so we'll change that one line.
chrome.runtime.sendNativeMessage(hostName, { text: "Ready" }, gotCredentials);
That's all it takes. Seriously. As long as your Host plays nice, this is the big secret. I won't even tell you how long it took me to find it!
Links:
My questions with helpful links:
Here - Workaround for Authenticating against Active Directory
Here - Also has some working code for a functional NM Host
Here - Some enlightening material on promises
So this turns out to be a non-trivial problem.
I haven't implemented the solution, yet, but I know how to get there...
Passing values to an extension is the first step - this can be done in both Chrome and Firefox. Watch the version to make sure the API required, nativeMessaging, actually exists in your version. I have had to switch to chromium for this reason.
Alternatively, one can use the storage API to put values in browser storage first. [edit: I did not go this way for security concerns]
Next is to use the onAuthRequired event from the webRequest API . Setup a listener on the event and pass in the values you need.
Caveats: I have built everything right up to the extension itself for the nativeMessaging API solution and there's still a problem with getting the script to recognise the data. This is almost certainly my JavaScript skills clashing with the arcane knowledge required to make these APIs make much sense ...
I have yet to attempt the storage method as it's less secure (in my mind) but it does seem to be simpler.

Troubleshooting Amazon's Alexa Skill Kit (ASK) Lambda interaction

I'm starting with ASK development. I'm a little confused by some behavior and I would like to know how to debug errors from the "service simulator" console. How can I get more information on the The remote endpoint could not be called, or the response it returned was invalid. errors?
Here's my situation:
I have a skill and three Lambda functions (ARN:A, ARN:B, ARN:C). If I set the skill's endpoint to ARN:A and try to test it from the skill's service simulator, I get an error response: The remote endpoint could not be called, or the response it returned was invalid.
I copy the lambda request, I head to the lambda console for ARN:A, I set the test even, paste the request from the service simulator, I test it and I get a perfectly fine ASK response. Then I head to the lambda console for ARN:B and I make a dummy handler that returns exactly the same response that ARN:A gave me from the console (literally copy and paste). I set my skill's endpoint to ARN:B, test it using the service simulator and I get the anticipated response (therefore, the response is well formatted) albeit static. I head to the lambda console again and copy and paste the code from ARN:A into a new ARN:C. Set the skill's endpoint to ARN:C and it works perfectly fine. Problem with ARN:C is that it doesn't have the proper permissions to persist data into DynamoDB (I'm still getting familiar with the system, not sure wether I can share an IAM role between different lambdas, I believe not).
How can I figure out what's going on with ARN:A? Is that logged somewhere? I can't find any entry in cloudwatch/logs related to this particular lambda or for the skill.
Not sure if relevant, I'm using python for my lambda runtime, the code is (for now) inline on the web editor and I'm using boto3 for persisting to DynamoDB.
tl;dr: The remote endpoint could not be called, or the response it returned was invalid. also means there may have been a timeout waiting for the endpoint.
I was able to narrow it down to a timeout.
Seems like the Alexa service simulator (and the Alexa itself) is less tolerant to long responses than the lambda testing console. During development I had increased the timeout of ARN:1 to 30 seconds (whereas I believe the default is 3 seconds). The DynamoDB table used by ARN:1 has more data and it takes slightly longer to process than ARN:3 which has an almost empty table. As soon as I commented out some of the data loading stuff it was running slightly faster and the Alexa service simulator was working again. I can't find the time budget documented anywhere, I'm guessing 3 seconds? I most likely need to move to another backend, DynamoDB+Python on lambda is too slow for very trivial requests.
Unrelated to python, but I have found the same issue occurs for me if I do not have a handler for a specified intent:
# lets pretend intentName is actually 'FooBarIntent'
if (intentName == 'TestIntent') {
handleTestRequest(intent, session, callback);
} else {
throw "Invalid intent";
}
From here, amazon was barking that my lambda was invalid. For others it could indicate an error is being thrown earlier in the stack.
You can also log out your lambda errors with aws cloudwatch which will reveal any warnings or errors.
check out my repo, alexa lambda starter kit for a a simple hello world ask/lambda example.
I think the problem you having for ARN:1 is you probably didn't set a trigger to alexa skill in your lambda function.
Or it can be the alexa session timeout which is by default set to 8 seconds.
My guess would be that you missed a step on setup. There's one where you have to set the "event source". IF you don't do that, I think you get that message.
But the debug options are limited. I wrote EchoSim (the original one on GitHub) before the service simulator was written and, although it is a bit out of date, it does a better job of giving diagnostics.
Lacking debug options, the best is to do what you've done. Partition and re-test. Do static replies until you can work out where the problem is.

Pepper API error during the example

I'm starting to play around with the new Pepper API for an important project (phasing out Java) and I'm having an issue with this example.
https://developer.chrome.com/native-client/devguide/devcycle/vs-addin
I've installed the plugin to VS, added the paths, started the python webserver yet when I debug it gives me a 404...
I'm starting the python webserver as per https://developer.chrome.com/native-client/sdk/examples
The issue being the HTML file it's looking for is in F:\nacl_sdk\vs_addin\examples\hello_world_gles\hello_world_gles and the localhost root is F:\nacl_sdk\pepper_42\getting_started
Has anyone else had this issue?
I also have plenty of intellisense errors:
Since I posted this I tried copying the example directory to the root directory being used by localhost. The page loads, however I'm not capable of running the plugin...
I think you're not supposed to be starting the Python web server, as per the vs addin documentation:
When you run one of the Native Client platforms Visual Studio builds
the corresponding type of Native Client module (either a .nexe or
.pexe), starts a web server to serve it up, and launches a copy of
Chrome that fetches the module from the server and runs it.
However, to be honest, I'm still unable to run this sample, even though I'm following this instruction. I'm seeing an "ERR_CONNECTION_REFUSED" result page. I'm using VS 2012 Express, and Chrome 43.
Update. I've finally managed to run the sample. First, I've installed VS 2012 Ultimate instead of Express (because Express doesn't support Add-Ins). Second, the latest VS addin seems to be unable to run the Python web-server, it passes the port paramater in a wrong format. You can see that if you read the output in the "Native Client Web Server Output" pane in VS. So what I did, is I modified the %NACL_SDK_ROOT%\tools\httpd.py, so that it doesn't attempt to parse the command line arguments :)
Here is the new main from my httpd.py:
def main(args):
server = LocalHTTPServer(os.path.abspath('.'), 5103)
# Serve until the client tells us to stop. When it does, it will give us an
# errorcode.
print 'Serving %s on %s...' % (options.serve_dir, server.GetURL(''))
return server.ServeForever()
HTH.

How AppEngine instances work on the local server

Newbie on appengine and I really don't know how to phrase the question which sadly results in me not knowing what keywords to google and I hope that i really do get help other than the bashing that a lot of people do.
I'm confused between the behavior of appengine online and the appengine on the local server.
Background info:
Btw this is in Python
Initially i assumed that , when needed or as authored
an instance of the app or module will be created.
And that instance will be the one serving multiple requests from different clients.
In this behavior any initialization code will only be run once.
But in the local development server.
Every time i add something new, specially in the main.py,
the server is able to catch the new changes,
then on browser-refresh be able to run it.
This made me think, wait...
Does it run the entire script over and over again
on every request?
Question:
Does an instance/module run the entire code on every request or is this just an added behavior to the dev server to make development easier?
Both your assumptions - about behaviour in production and development - are wrong.
In production, GAE spins up instances as required. This may be in response to increased load, or the host may simply decide after a certain amount of time to recycle an instance by killing it and starting a new one. Initialization code will always be run whenever a new instance is started.
In development, you only get a single instance. However, the server watches your file system for changes. If it detects a change to the code itself, it will restart itself, and therefore re-run the initialization code. But if you don't make any code changes between requests, the existing process continues indefinitely, and init code will not be re-run.
