Here is my test in Angular2:
it('should initialize without DI service',
async(inject([TestComponentBuilder], (tcb: TestComponentBuilder) => {
var template = '<component></component>';
return tcb.overrideTemplate(TestComponent, template)
.createAsync(TestComponent)
.then((fixture ) => {
expect(fixture.debugElement.children[0].componentInstance).toBeAnInstanceOf(ComponentType);
expect(fixture.debugElement.children[0].componentInstance.state).toBeNull();
});
})));
It throws the following error:
Uncaught (in promise): TypeError:
testing_1.expect(...).toBeAnInstanceOf is not a function
It works fine in Angular2 RC2 till I updated to RC4.
Since this has been unanswered for a long time, this other post might be helpful for the future:
Uncaught TypeError: ctorParameters.map is not a function

I want to add tracks in my stream with addTrack method and when I call addTrack method throws error
navigator.mediaDevices
.getDisplayMedia({ video: true, audio: true })
.then((stream) => {
peersRef.current.forEach((element) => {
const vidTrack = stream.getVideoTracks()[0];
element.peer.addTrack(
stream.getVideoTracks()[0],
element.peer.streams[0]
);
//console.log(stream.getVideoTracks()[0]);
//console.log(userVideo.current.srcObject.getVideoTracks()[0]);
});
});
when I adding track i got error with my simple-peer

I am using for the first time the aurelia-testing package to test my HTML code.
I seem to have followed the docs to set up my test as follows:
describe('Contextual Menu HTML View test suite', function () {
let component: ComponentTester;
beforeEach(function () {
component = StageComponent
.withResources('../../src/components/modal/contextual-menu')
.inView('<contextual-menu is-active.two-way="activateMenu"></contextual-menu>')
.boundTo({ activateMenu: false });
});
it('should not add the is-active class to the root element', async function () {
await component.create(bootstrap);
const rootElement = await waitForDocumentElement('.qa-contextual-menu');
expect(rootElement.classList.contains('is-active')).toBe(false);
});
afterEach(function () {
component.dispose();
});
});
I tried using just bind instead of two-way but that fails too.
I tried both with a document.querySelector and with waitForDocumentElement, both cases fail, but anyways I assume the error comes from earlier.
I am getting an error and I am not sure why. Could you put on the tracks to identify the root cause of the following:
TypeError: Failed to execute 'replaceChild' on 'Node': parameter 1 is not of type 'Node'.

Thanks a lot
I am not a jest user. So I simply used the scaffolded TS jest skeleton app from aurelia-cli (au new jest-skeleton --unattended --select typescript,jest,vscode). And found that to be working.
It seems the you are missing the following configuration in your jest.config.js.
testEnvironment: "node",
After only adding that, the tests started working.
I am trying to login to a form written in angular js but cypress throws the following exception:
Uncaught TypeError: $(...).materialScrollTop is not a function
This error originated from your application code, not from Cypress.
When Cypress detects uncaught errors originating from your application it will automatically fail the current test.
This behavior is configurable, and you can choose to turn this off by listening to the 'uncaught:exception' event.
https://on.cypress.io/uncaught-exception-from-application
This is the cypress login code:
context('TestLogin', () => {
it('Test Login', () => {
cy.visit('url');
cy.get('input[id=Email]').type('email', {force: true});
cy.get('input[id=Password]').type('passcode', { force: true });
cy.get('button[type=submit]').click();
})
})
Since the login has a csrf token, I have used cy.request() as follows and I do get a response with status code 200 but when re-loading the site it goes back to login page.
describe("Tests for AntiForgeryToken", function () {
// variable from config, that contain Identity Server URL
const identityUrl = Cypress.config("identityServerUrl")
// command declaration that we are going to use in tests
// allows us to create request to server
Cypress.Commands.add("loginByToken", function (token, login, password) {
cy.request({
method: "POST",
failOnStatusCode: false,
url: `${identityUrl}/Account/Login`,
form: true,
body: {
email: login,
password: password,
__RequestVerificationToken: token,
RememberLogin: false
}
})
})
it("Should parse token from response body and return 200", function () {
cy.request(`${identityUrl}/Account/Login`)
.its("body")
.then((body) => {
const $html = Cypress.$(body)
// when the page is rendered
// we are trying to find the Request Token in the body of page
const token = $html.find("input[name=__RequestVerificationToken]").val()
// POST request with token and login data
// then we simply verify whether Indentity Server authorized us
cy.loginByToken(token, "test#test.com", "Test_1234")
.then((resp) => {
expect(resp.status).to.eq(200)
})
})
cy.visit(`${identityUrl}/Account/`);
})
Cypress documentation didn't provide much info about the exception.
Any insights from cypress experts are helpful.
As evident from the error, Cypress is failing the test as it found an exception in your application,this is not a cypress level exception but an uncaught exception in your app which is causing cypress to fail the test, this is pretty useful as you can check if its an actual error in your app and log it for the dev team to fix, check if you are able to reproduce this manually, either way i think the application code should be fixed to either fix the bug or catch the exception and return a valuable error message. If you want to disable this feature you can turn off all uncaught exception handling, so in your index.js or whatever file is the entry point add the following:
Cypress.on('uncaught:exception', (err, runnable) => {
// returning false here prevents Cypress from
// failing the test
// you can also add a Debugger here to analyze the error
debugger;
return false;
});
not sure if turning this off will help as looks like there is something in your application which could be an issue, but this is just for informational purposes that you can turn this feature off if you needed to.
Here is the documentation for further reading : Cypress Events documentation
hope this helps
I am trying to fetch data from a simple get request using Titanium.Network.HTTPClient
Here is the code
var url = "http://www.appcelerator.com"; //Here i have my get api URL, i have also tried replacing the url with google.com
var client = Ti.Network.createHTTPClient({
// function called when the response data is available
onload : function(e) {
Ti.API.info("Received text: " + this.responseText);
alert('success');
},
// function called when an error occurs, including a timeout
onerror : function(e) {
Ti.API.debug(e.error);
alert('error');
},
timeout : 5000 // in milliseconds
});
// Prepare the connection.
client.open("GET", url);
// Send the request.
client.send();
But the app is crashing with error Uncaught TypeError: Cannot read property 'extendModel' of undefined, I am not using any model, It is a new project with the above mentioned code, nothing more.
Here is the screenshot of error
Please help!
EDIT
Configuration details:
Titanium Command-Line Interface, CLI version 5.0.13
Titanium SDK

Node version v4.8.2
Please let me know if any further details required,
Error is:

}
Adding this to a common function used in config/http.js worked.
