It may be a dumb question, but I just cannot figure out why sometimes Swal.fire works and sometimes it doesn't.
The alert I am using is quite simple -
Swal.fire({
title:'Slow response!',
text:'Please indicate the side as quickly and accurately as possible',
icon:'warning'
})
But it only works when within a function starts as:
$(document).keydown(function (e) {...})
Since this function is built in a constructor, I add .bind(this) at the end to make use of "this" object. Nevertheless, my sweetalert does not work in this situation. It also does not work if the inner function starts as:
$(document).keydown((e)=> {...})
I did not see any errors in console. Any comments are highly appreciated!

It seems that most people I read about experence zero trouble with this. I, on the other hand, have a test suite which someone else wrote, in which I'm trying to replace route() with intercept(). The API intercepts are done to handle button clicks etc., and about 99.9% percent of them fails if I just replace it. So, there's obviously some syntax in/use of intercept() I've not found a description for.
Example:
This works:
cy.route('POST', getApiPrefix() + '/prosjektfinansiering/'+ pfId +'/eiendom', result);
This does not work. The button click is not executed:
cy.intercept('POST', getApiPrefix() + '/prosjektfinansiering/'+ pfId +'/eiendom', result);
I've tried adding '**' in front of "/prosjekt...", and I've tried removing 'POST', with no luck.
Any ideas? I'll gladly post more info if necessary.
UPDATE:
Futher attempts:
Getting some hints here and there, it seems that this is a more correct way of using intercept():
return cy.intercept('POST', getApiPrefix() + '/prosjektfinansiering/'+ pfId +'/eiendom', {
body: result
});
This doesn't work, either.
The variables result in these examples is an object describing what is sent back to the frontend of the POST-request in the route matches the api path.
For troubleshooting, I can see that when using intercept(), there is ONE route that is not working when using intercept (the bottom one in the picture). However, I cannot for the life of me see why, and how the route match can be written differently?
Most likely, you're mixing the old use of cy.route() and cy.server(). In my experience, those two won't work well together. It's easier when you're starting fresh with just cy.intercept().
Your update is correct too; You have to encapsulate the return value you want mocked in {body: value}.
from what I am seeing in your circled screenshot, the API is not called after you try to intercept it. (the count under # column is -)
You need to track when the API is to be called and ensure you intercept before the call is made. Cypres can help you with this. You can go through the run steps in the cypress window.
You could also share this if you don't mind.
If you are 100% certain the button makes the call. Steps should be:
cy.intercept()
cy.get('button').click()
In the cypress window, right after the click, you should see the API being called.
New cypress user here, I am aware that cypress does not handle variables like how testcafe and others do due to the asyn nature of it. Using the example given and what I could find I have this as an example:
cy.get('selector').invoke('text').as('text_needed')
cy.get('#text_needed')
const txtneeded = this.text_needed
cy.log(txtneeded)
This looks at a given selector, takes what it finds and uses it as text and set it as a variable usable at any time in the test and outputs it to the log. The plan is to use that text in a search filter in another page to find the item it references.
The problem is that it fails with Cannot read properties of undefined (reading 'text_needed')
Is this because the content of the selector is not assigned to text properly, the outer html is <a data-v-78d50a00="" data-v-3d3629a7="" href="#">PO90944</a> The PO90944 is what I want to capture.
Your help would be appreciated!
You cannot save an alias and access it via this.* in the same execution context (callback) because it's a synchronous operation and your alias is not yet resolved at this time.
This is a correct way to go:
cy.get('selector').invoke('text').as('text_needed')
cy.get('#text_needed').then(txtneeded => {
cy.log(txtneeded)
})
First, make sure to define it as traditional function, not as an arrow function as this context doesn't work as you'd expect there, more info here.
Next, typically in a single test you should use .then() callback to perform additional actions on elements, and use aliases when you need to share context between hooks or different tests, so please consider the following:
// using aliases together with this within the single test won't work
cy.get(<selector>).invoke('text').as('text_needed')
cy.get('#text_needed').should('contain', 'PO90944') // works fine
cy.log(this.text_needed) // undefined
// this will work as expected
cy.get(<selector>).invoke('text').then(($el) => {
cy.wrap($el).should('contain', 'PO90944'); // works fine
cy.log($el) // works fine
});
Setting alias in beforeEach hook for example, would let you access this.text_needed in your tests without problems.
Everything nicely explained here.
Edit based on comments:
it('Some test', function() {
cy.visit('www.example.com');
cy.get('h1').invoke('text').as('someVar');
});
it('Some other test', function() {
cy.visit('www.example.com');
cy.log('I expect "Example Domain" here: ' + this.someVar);
});
And here's the output from cypress runner:
The Cypress documentation suggests that commands are the right way to reuse fragments of code, e.g.
Cypress.Commands.add("logout", () => {
cy.get("[data-cy=profile-picture]").click();
cy.contains("Logout").click();
});
cy.logout();
For simple cases like this, why would I use a command over a plain JS function (and all the nice IDE assistance that comes with it). What are the drawbacks of rewriting the above snippet as
export function logout(){
cy.get("[data-cy=profile-picture]").click();
cy.contains("Logout").click();
}
// and now somewhere in a test
logout();
Based on my experience with Cypress (one year project and several hundred test cases), I can say that a plan JS function is great for grouping cy commands.
From my point of view, a custom cy command may be really useful only if it is incorporated into the chain processing (utilizes the subject parameter or returns a Chainable to be used further in the chain). Otherwise, a plain JS function is preferable due to it simplicity and full IDE support (unless you're using an additional plugin).
If you for any reason need to do something inside the cypress loop, you can always wrap you code by cy.then() in a plain JS function:
function myFunction() {
cy.then(() => {
console.log(("I'm inside the Cypress event loop"))
})
}
Commands are for behavior that is needed across all tests. For example, cy.setup or cy.login. Otherwise, use functions.

I have been using mocha-casperjs for a while now and I noticed that for some reason, sometimes code like:
casper.click(x("//a[normalize-space(text())='login']"));
or
casper.waitForSelector(x("//a[normalize-space(text())='login']")
don't work immediately, but it fails saying:
xpath selector: //a[normalize-space(text())='login']" still did not exist 5000ms
After some attempts, it just works, but than it doesn't anymore again.
It is not an asynchronous problem, because I use code like:
if(casper.exists(x("//a[normalize-space(text())='login']"))){
console.log('I am here');
}
to test its presence and this always returns "I am here".
Any idea ?
So, I think the problem I was having is related to this question.
The question I have linked to, led me to further testing and to the solution. All the time my tests were failing, it was because I was actually already logged in, so x("//a[normalize-space(text())='login']") wasn't there obviously.
The fact that the below code returned "I am here", it was because I was doing in the wrong way.
if(casper.exists(x("//a[normalize-space(text())='login']"))){
console.log('I am here');
}
Another thing I did wrongly that it might help someone and that I totally missed, is that I moved casper.start and casper.run outside describe("", function(){...}) like:
casper.start();
describe("", function(){
it("...", function(){..})
it("...", function(){..})
});
casper.run(function(){
test.done();
});
I hope this helps someone.
Thanks.
Even though I've been using mootools for a while now, I haven't really gotten into playing with the natives yet. Currently I'm trying to extend events by adding a custom addEvent method beside the original. I did that using the following code(copied from mootools core)
Native.implement([Element, Window, Document], {
addMyEvent:function(){/* code here */}
}
Now the problem is that I can't seem to figure out, how to properly overwrite the existing fireEvent method in a way that I can still call the orignal method after executing my own logic.
I could probably get the desired results with some ugly hacks but I'd prefer learning the elegant way :)
Update: Tried a couple of ugly hacks. None of them worked. Either I don't understand closures or I'm tweaking the wrong place. I tried saving Element.fireEvent to a temporary variable(with and without using closures), which I would then call from the overwritten fireEvent function(overwritten using Native.implement - the same as above). The result is an endless loop with fireEvent calling itself over and over again.
Update 2:
I followed the execution using firebug and it lead me to Native.genericize, which seems to act as a kind of proxy for the methods of native classes. So instead of referencing the actual fireEvent method, I referenced the proxy and that caused the infinite loop. Google didn't find any useful documentation about this and I'm a little wary about poking around under the hood when I don't completely understand how it works, so any help is much appreciated.
Update 3 - Original problem solved:
As I replied to Dimitar's comment below, I managed to solve the original problem by myself. I was trying to make a method for adding events that destroy themselves after a certain amount of executions. Although the original problem is solved, my question about extending natives remain.
Here's the finished code:
Native.implement([Element, Window, Document], {
addVolatileEvent:function(type,fn,counter,internal){
if(!counter)
counter=1;
var volatileFn=function(){
fn.run(arguments);
counter-=1;
if(counter<1)
{
this.removeEvent(type,volatileFn);
}
}
this.addEvent(type,volatileFn,internal);
}
});
is the name right? That's the best I could come up with my limited vocabulary.
document.id("clicker").addEvents({
"boobies": function() {
console.info("nipple police");
this.store("boobies", (this.retrieve("boobies")) ? this.retrieve("boobies") + 1 : 1);
if (this.retrieve("boobies") == 5)
this.removeEvents("boobies");
},
"click": function() {
// original function can callback boobies "even"
this.fireEvent("boobies");
// do usual stuff.
}
});
adding a simple event handler that counts the number of iterations it has gone through and then self-destroys.
think of events as simple callbacks under a particular key, some of which are bound to particular events that get fired up.
using element storage is always advisable if possible - it allows you to share data on the same element between different scopes w/o complex punctures or global variables.
Natives should not be modded like so, just do:
Element.implement({
newMethod: function() {
// this being the element
return this;
}
});
document.id("clicker").newMethod();
unless, of course, you need to define something that applies to window or document as well.
