playwright find child element(s) within locator - automation

I'm trying to write a function to find child(ren) element(s) within a locator something like:
async findElements(locator: Locator){
return locator.querySelector(some/xpath/or/css);
}
However, I'm seeing the querySelector is not available in Locator. What is the equivalent of querySelector?

I figured it out,
locator.locator(some/xpath/)

I have just started working with playwright. So this may not be the exact answer that are looking for.
I am studying playwright with an existing repository.
[https://github.com/twerske/ng-tube/blob/main/src/app/video-grid/video-grid.component.html]
In this scenario I just want to know that I am getting a list of cards back.
<div class="videos-grid">
<mat-card *ngFor="let video of videos" class="video-card">
I don't need a reference to a parent for this situation. I am able to simply reference the child by class videos-grid. This all exists inside of a angular's For loop. I know Svelte and other frameworks iterate through lists in different ways.
test.only('ngTube has header and cardList', async ({browser}) => {
const page = await browser.newPage();
const context = await browser.newContext();
await page.goto("http://localhost:4200/")
const title = await page.locator('.header-title').textContent();
const videoList = (await page.locator('.video-card').allTextContents()).length;
// await page.pause();
expect(title).toStrictEqual('ngTube');
expect(videoList).toBeGreaterThan(0)
})
Because I want all text contents I can get everything with the classname '.video-card'.
I guess what I am getting at is as long as you can access an identifier you should be able to directly access it. As I run through the documentation more and scenarios I will update/add to this answer.

React Native cheerio.load() not working properly neither is JSDOM library

Well I'm new to this app development thing especially react-native and I wanted to know when I'm trying to scrap a website using cheerio and axios in react-native and then save it to firebase realtime database in the following way:
and yes i have done all the imports and also initalized my app using firebaseConfig
const db = firebase.database();
async function loadFurniture() {
const Url = 'https://hoid.pk/product-category/bedroom/beds-bedroom/';
const html = await axios.get(Url); // fetch page
const $ = cheerio.load(html); //parse html String
const furniture = [];
$('.product-wrapper ').each((i, element) => {
const title = $(element).find('h2.product-name').text();
const imageUrl = $(element).find('img.primary_image').attr('src');
const price = $(element).find('span.woocommerce-Price-amount amount').text();
console.log(title);
furniture.push({ title, imageUrl, price });
});
// Save the furniture to the Firebase Realtime Database
db
.ref('/furniture/bed')
.set({
title: furniture.title,
price: furniture.price,
object_image : furniture.imageUrl,
})
.then(() => console.log('Data set.'));
console.log(furniture);
// Return the extracted information
return furniture;
}
and then calling this function in a button
<Button
title="Fetch"
onPress = {() => loadFurniture() }
/>
The data was not being scraped so I tried to console.log() the data being fetched.
Whenever I click the button there is no error but just a log [ Function initialize ] with respect to console.log(title)
And before anyone says yup I've looked into the structure and 9it does returns me my desired classes after axios.get()
I just want to know that if there's some error in my code or if I'm going wrong somewhere.
I tried to scrap furniture titles, images and prices from certain website and then save it to database for any further use but it's just not working.
I've checked my network issues the html page being scraped and everything else one can think of. Now i just want to know either my code is accurate or if there's some mistake.
I tired to scrap the data of same website using python and it scraps it perfectly.
Edit:
I found out that the cheerio.load() function is not working there was no problem with the database... Is there some problem with cheerio.load() in it's latest version "1.0.0-rc.12" ?? If so what's the solution... I've tried number of libraries and each is giving a different kind of error so cheerio might be the only possible solution so if there's an alternative way of using cheerio.load() in react native do let me know.

Automating mat-option in testcafe

Tried automating dropdown using the below methods but the dropdown values couldn't be selected.
Method 1:
const comboOption = Selector("mat-option").child("span").withExactText("Hello");
await t.click(comboOption);
Method 2:
ClientFunction(() => {
document.getElementsByClassName('mat-option-text')[0].innerText = 'Hello';
document.getElementsByClassName('mat-option-text')[0].click();
return "Hello";});
The mat-option tag is not within mat-select. It is outside mat-select and within div tag.
Are there other ways to achieve automating mat-option ?
Thank you for the code snippets.
As far as I understand, you are trying to click an option element in another select element.
I created a simple test that should perform the steps you described:
import { Selector } from 'testcafe';
fixture`Getting Started`
.page`http://devexpress.github.io/testcafe/example`;
const selectElement = Selector('#preferred-interface');
const optionElement = selectElement.find('option');
test('My first test', async t => {
await t
.click(selectElement)
.click(optionElement.withText('Both'))
.expect(selectElement.value).eql('Both');
});
If I misunderstood your question, could you please share a simple example of your .html and a detailed description of
what you want to do in the test and which results you expect?

Cycle through test data from within a Testcafe test? How to?

I'm wanting to log into an app, run several searches from test data, then log out. I don't want to login and out for each item in the data set, which would be the case if I coded this way...
dataSet.forEach(data =>{
test('Search Test', async t => {......
I would like to be able to...
test('Search Test', async t => {......
foreeach(data in Data set)
call a function to search
call a function to verify search return.
Something like this...
test('Simple Search Test', async t => {
//await t
await loginPage.login(loginName, password);
await t
.expect(getURL()).contains('home')
// Check logged in user display...
.expect(pageHeader.userName.withText(data.loggedInUser).visible).ok()
dataSet.forEach(data =>{
leftSidebar.searchWithCriteria(data.criteria, 'Filename');
recordNav.verifyTotal(data.srchresult);
});
// Log out
await pageHeader.logout();
await t
.expect(loginPage.copyRight.visible).ok();
});
enter code here
I've tried everything, but can't get it to work. Is this possible or does the entire test have to be run for each data record in the set?
TestCafe allows you to loop through test code in any manner, including iterating through custom data.
To help us determine why this does not work for you, please provide an example that I can run on my machine (including the test code, page object, and the tested page's URL).
I got it to work using this...
for (var i = 0; i < dataSet.length; i++){
leftSidebar.searchWithCriteria(dataSet[i].criteria, 'Filename');
recordNav.verifyTotal(dataSet[i].srchResult);
}

How to use store.filter / store.find with Ember-Data to implement infinite scrolling?

This was originally posted on discuss.emberjs.com. See:
http://discuss.emberjs.com/t/what-is-the-proper-use-of-store-filter-store-find-for-infinite-scrolling/3798/2
but that site seems to get worse and worse as far as quality of content these days so I'm hoping StackOverflow can rescue me.
Intent: Build a page in ember with ember-data implementing infinite scrolling.
Background Knowledge: Based on the emberjs.com api docs on ember-data, specifically the store.filter and store.find methods ( see: http://emberjs.com/api/data/classes/DS.Store.html#method_filter ) I should be able to set the model hook of a route to the promise of a store filter operation. The response of the promise should be a filtered record array which is a an array of items from the store filtered by a filter function which is suppose to be constantly updated whenever new items are pushed into the store. By combining this with the store.find method which will push items into the store, the filteredRecordArray should automatically update with the new items thus updating the model and resulting in new items showing on the page.
For instance, assume we have a Questions Route, Controller and a model of type Question.
App.QuestionsRoute = Ember.Route.extend({
model: function (urlParams) {
return this.get('store').filter('question', function (q) {
return true;
});
}
});
Then we have a controller with some method that will call store.find, this could be triggered by some event/action whether it be detecting scroll events or the user explicitly clicking to load more, regardless this method would be called to load more questions.
Example:
App.QuestionsController = Ember.ArrayController.extend({
...
loadMore: function (offset) {
return this.get('store').find('question', { skip: currentOffset});
}
...
});
And the template to render the items:
...
{{#each question in controller}}
{{question.title}}
{{/each}}
...
Notice, that with this method we do NOT have to add a function to the store.find promise which explicitly calls this.get('model').pushObjects(questions); In fact, trying to do that once you have already returned a filter record array to the model does not work. Either we manage the content of the model manually, or we let ember-data do the work and I would very much like to let Ember-data do the work.
This is is a very clean API; however, it does not seem to work they way I've written it. Based on the documentation I cannot see anything wrong.
Using the Ember-Inspector tool from chrome I can see that the new questions from the second find call are loaded into the store under the 'question' type but the page does not refresh until I change routes and come back. It seems like the is simply a problem with observers, which made me think that this would be a bug in Ember-Data, but I didn't want to jump to conclusions like that until I asked to see if I'm using Ember-Data as intended.
If someone doesn't know exactly what is wrong but knows how to use store.push/pushMany to recreate this scenario in a jsbin that would also help too. I'm just not familiar with how to use the lower level methods on the store.
Help is much appreciated.
I just made this pattern work for myself, but in the "traditional" way, i.e. without using store.filter().
I managed the "loadMore" part in the router itself :
actions: {
loadMore: function () {
var model = this.controller.get('model'), route = this;
if (!this.get('loading')) {
this.set('loading', true);
this.store.find('question', {offset: model.get('length')}).then(function (records) {
model.addObjects(records);
route.set('loading', false);
});
}
}
}
Since you already tried the traditional way (from what I see in your post on discuss), it seems that the key part is to use addObjects() instead of pushObjects() as you did.
For the records, here is the relevant part of my view to trigger the loadMore action:
didInsertElement: function() {
var controller = this.get('controller');
$(window).on('scroll', function() {
if ($(window).scrollTop() > $(document).height() - ($(window).height()*2)) {
controller.send('loadMore');
}
});
},
willDestroyElement: function() {
$(window).off('scroll');
}
I am now looking to move the loading property to the controller so that I get a nice loader for the user.

How to structure a complex web app with RequireJS

I saw there is somes questions related to mine (like this interesting one), but what I wonders is how to do it correctly, and I couldn't find it via the others questions or the RequireJS documentation.
I'm working on a quite heavy web application that will run in only one html page.
Before RequireJS, I used to do a lot of JS modules with public methods and connecting them via the on event on the Dom READY method, like this :
var DataList = function () {
this.base = arguments[0];
this.onUpdate = function (event) { ... }
}
$(function () {
var dataList = {}; DataList.apply(dataList, [$('#content')]);
$('table.main', dataList.base).on ('update', dataList.onUpdate);
});
With RequireJS, I can easily see that I can split DataList and all others classes like this on individual files, but what about the $(function () {}); part?
Can I still keep it this way, but instead of the DOM ready function of jQuery, I put the events on the main function() of the RequireJS, when my primary libs are loaded?
Or do I have to change the way I create JS "classes", to include a init function maybe, that will be called when I do a, for example :
require(['Datalist'], function(dataList) {
dataList.init($('#content'));
});
What annoys me the most is that since I have only one html file, I'm afraid the require() will have to load a huge list of files, I'd prefer it to load just libs that, them, would load sub libs required to work.
I don't know, the way of thinking with RequireJS lost me a bit :/
How would you do?
"Can I still keep it this way, but instead of the DOM ready function of jQuery, I put the events on the main function() of the RequireJS, when my primary libs are loaded?"
If you separate the functions or 'classes' into modules then you can use the RequireJS domReady function:
require(['module1'], function(module1) {
domReady(function(){
// Some code here ftw
})
});
The benefit here is the domReady function will allow downloading of the modules instantly but won't execute them until your DOM is ready to go.
"Or do I have to change the way I create JS "classes", to include a init function maybe, that will be called when I do a, for example"
You won't need to change the way you interact with your code this way, but you can probably improve it. In your example I would make DataList a module:
define(function(require) {
var $ = require('jquery');
var DataList = function () {
this.base = arguments[0];
};
DataList.prototype.onUpdate = function() {
};
return DataList;
});
require(['data-list'], function(DataList) {
var data = {};
// Call DataList with new and you won't need to set the context with apply
// otherwise it can be used exactly as your example
new DataList(data);
});
"What annoys me the most is that since I have only one html file, I'm afraid the require() will have to load a huge list of files, I'd prefer it to load just libs that, them, would load sub libs required to work."
Make your code as modular as you want/can and then use the optimiser to package it into one JS file.
