I am deploying the jupyterlab on k8s, it uses below kernel.json and creates runtime connection file and load kernel once start the notebook, console and pyspark, however i didnt find runtime connection file when starting terminal.
for example if I load notebook then the runtime file created as below:
/opt/spark/work-dir/.local/share/jupyter/runtime/kernel-xxxxxxxxxxxx-4x9e-xxx5-b32f7xxxxxx.json
{
"shell_port": 37215,

}

"argv": ["/usr/bin/python", "-m", "ipykernel", "-f", "{connection_file}"],
"env": {

"PYSPARK_PYTHON": "/usr/bin/python",

}
}
There is no error reported on log for this failure, I am only getting this message whenever loading the Terminal.

Normal tests work fine. As far as I can tell I am following the example correctly. The test assertions work correctly it just appears at the end of the test run.

})
.end()
}
}
Executing by typing nightwatch from the terminal like I would other tests. Any ideas and is this the best accessibility assertion library for NightwatchJS?
I ended up using nightwatch-axe-verbose instead. Usage details included on this web accessibility testing using nightwatch blog post.
I'm using Nightwatch.js and trying to run E2E tests using the programmatic API as described here.
Here is my nightwatch.json file:
{
"src_folders": ["tests"],
"webdriver": {
"start_process": true,
"server_path": "node_modules/.bin/chromedriver",
"port": 9515
},
"test_settings": {
"default": {
"desiredCapabilities": {
"browserName": "chrome"
}
}
}
}
and index.js script:
const Nightwatch = require('nightwatch');
Nightwatch.runTests(require('./nightwatch.json')).then(() => {
console.log('All tests has been passed!');
}).catch(err => {
console.log(err);
});
When I run the script I get the error:
Error: An error occurred while retrieving a new session: "Connection refused to 127.0.0.1:9515". If the Webdriver/Selenium service is managed by Nightwatch, check if "start_process" is set to "true".
I feel it needs some configuration but the documentation isn't very helpful here.
This is my part of my config:
"selenium": {
"start_process": true, // tells nightwatch to start/stop the selenium process
"server_path": "./selenium-server-standalone-3.8.1.jar",
"host": "127.0.0.1",
"port": 4444, // standard selenium port
"cli_args": {
"webdriver.chrome.driver": "./chromedriver_win32/chromedriver.exe"
}
},
test_settings" : {
"default" : {
"use_ssl": true,
"credentials": {
"username": "admin",
"key": "secret"
},
The test was running fine until I inserted use_ssl. Now I am getting this error:
Error retrieving a new session from the selenium server
Connection refused! Is selenium server started?

I am trying to test a page which requires windows authentication.
I have attempted to ask this previously, buy got no real answers, and have now been struggling for over a month.
I just cannot get my ajax calls to work on an Ionic 3 Cordova application built for a Windows 10 UWP. They can access localhost, but not any outside connections.
The application works fine on both Android and iOS.
I am trying to test this locally on my dev machine. I use a certificate (bought) to sign the application, install this certificate, build the application for Windows, and am able to open up the built CordovaApp.Windows10_1.0.1.1_x86.appxupload, and then double click the embedded CordovaApp.Windows10_1.0.1.1_x86.appx file to install, which completes successfully. The install indicates the app need internet access.
In the config.xml, I have the following tags, as suggested elsewhere...
<allow-navigation href="*" />
<access origin="*" />
However, when I run, the http.get call just returns 0 with no other information. I can run in Visual Studio, and look at the returned error object, and get no further info, apart from this 0 return.
I have run fiddler, enabled the https decryption as explained here, but all I see in the response header is
HTTP/1.0 200 Connection Established
FiddlerGateway: Direct
StartTime: 13:44:21.686
Connection: close
The result in the main view actually shows 200, so I don't think this is showing me anything real.
I am at a complete loss. I have no where else to search. What could I be missing?
Should I be able to use external ajax on a Windows 10 machine, when I have sideloaded the application as here? I haven't tried from the store yet, as I don't want to upload until I know it works.
Any suggestions desperately welcomed. Surely someone has had an Ionic 3 application accessing external ajax working?
Thanks in advance for any help
[UPDATE 1]
If I run the application on the same machine, just using Ionic serve (so it just runs in the browser rather than hosted in the UWP), the ajax calls also work fine.
[UPDATE 2]
I have now created a Cordova application using the Visual Studio template, so taking all other frameworks out of the equation.
I used vanilla JavaScript to do my rest call...
document.addEventListener('deviceready', callUrl, false);
function callUrl() {
console.log('callUrl');
var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://myserveraddress.com/myapp/testroute');
xhr.send(null);
xhr.onreadystatechange = function () {
var DONE = 4; // readyState 4 means the request is done.
var OK = 200; // status 200 is a successful return.
if (xhr.readyState === DONE) {
if (xhr.status === OK)
console.log(xhr.responseText);
} else {
console.log('Error: ' + xhr.status);
}
}
};
I run this in the debugger, and even here I get an error (status code of 0).
Another thing I noticed when I open up the build package and look at the cordova_plugins.js file..
My Ionic app has the following...
cordova.define('cordova/plugin_list', function(require, exports, module) {
module.exports = [
{
"id": "cordova-plugin-console.logger",
"file": "plugins/cordova-plugin-console/www/logger.js",
"pluginId": "cordova-plugin-console",
"clobbers": [
"cordova.logger"
]
},
{
"id": "cordova-plugin-console.console",
"file": "plugins/cordova-plugin-console/www/console-via-logger.js",
"pluginId": "cordova-plugin-console",
"clobbers": [
"console"
]
},
{
"id": "cordova-plugin-device.device",
"file": "plugins/cordova-plugin-device/www/device.js",
"pluginId": "cordova-plugin-device",
"clobbers": [
"device"
]
},
{
"id": "cordova-plugin-device.DeviceProxy",
"file": "plugins/cordova-plugin-device/src/windows/DeviceProxy.js",
"pluginId": "cordova-plugin-device",
"merges": [
""
]
},
{
"id": "cordova-plugin-splashscreen.SplashScreen",
"file": "plugins/cordova-plugin-splashscreen/www/splashscreen.js",
"pluginId": "cordova-plugin-splashscreen",
"clobbers": [
"navigator.splashscreen"
]
},
{
"id": "cordova-plugin-splashscreen.SplashScreenProxy",
"file": "plugins/cordova-plugin-splashscreen/www/windows/SplashScreenProxy.js",
"pluginId": "cordova-plugin-splashscreen",
"runs": true
},
{
"id": "cordova-plugin-statusbar.statusbar",
"file": "plugins/cordova-plugin-statusbar/www/statusbar.js",
"pluginId": "cordova-plugin-statusbar",
"clobbers": [
"window.StatusBar"
]
},
{
"id": "cordova-plugin-statusbar.StatusBarProxy",
"file": "plugins/cordova-plugin-statusbar/src/windows/StatusBarProxy.js",
"pluginId": "cordova-plugin-statusbar",
"runs": true
},
{
"id": "ionic-plugin-keyboard.KeyboardProxy",
"file": "plugins/ionic-plugin-keyboard/src/windows/KeyboardProxy.js",
"pluginId": "ionic-plugin-keyboard",
"clobbers": [
"cordova.plugins.Keyboard"
],
"runs": true
}
];
module.exports.metadata =
// TOP OF METADATA
{
"cordova-plugin-console": "1.0.5",
"cordova-plugin-device": "1.1.4",
"cordova-plugin-splashscreen": "4.0.3",
"cordova-plugin-statusbar": "2.2.2",
"cordova-plugin-whitelist": "1.3.1",
"ionic-plugin-keyboard": "2.2.1"
};
// BOTTOM OF METADATA
});
Now, I notice every plugin in the module.exports.metadata also has an entry in the module.exports EXCEPT for cordova-plugin-whitelist!
If I open the same file for the Corvoda application created in VS, I see the following...
cordova.define('cordova/plugin_list', function(require, exports, module) {
module.exports = [];
module.exports.metadata =
// TOP OF METADATA
{
"cordova-plugin-whitelist": "1.2.2"
};
// BOTTOM OF METADATA
});
So this has nothing else for the whitelist plugin as well
Could there be something missing here?? Could this white-list plugin not be installed correctly?
I had a similar situation where my ajax calls worked fine in TEST, but when I moved to PROD, they would fail.
The answer was finally tracked down as a missing intermediary certificate on the server I was trying to access. TEST had the cert, PROD did not.
I hope this helps.
