How to use videoCapture.getChapters method in Cypress

The shorthand id selector #myid can only be used with the exact value, but id is still an attribute so you can use an attribute selector with a wildcard

cy.get('[id$="_2"]')         // $= means value ending with 

There's a bunch variations, see Selectors - Attribute

The other approach you tried should work like this

cy.get('div[data-collect-as="input"] input') 

This gets a child input with ancestor div[data-collect-as="input"] - the space denoting two separate elements and the relationship is ancestor -> descendant.

You can add more precision

cy.get('div[data-collect-as="input"] > div.wrp > input') 

where the > indicates a parent-child relationship.

You can make use of the task shown in this question How can I verify if the downloaded file contains name that is dynamic

/cypress/plugins/index.js

const fs = require('fs');

on('task', {
  downloads:  (downloadspath) => {
    return fs.readdirSync(downloadspath)
  }
})

This returns a list of the files in the downloads folder.

Ideally you'd make it easy on yourself, and set the trashAssetsBeforeRuns configuration. That way, the array will only contain the one file and there's no need to compare arrays before and after the download.

(Just noticed you have a task for it).

I was able to solve this by

//cypress/support/index.js

Cypress.Server.defaults({
  ignore: xhr => {
    return Cypress.config().blockHosts.some(blockedHost =>  // get blockHosts from cypress.json using Cypress.config()
      Cypress.minimatch(new URL(xhr.url).host, blockedHost)  // if current url matches any blockedHost item, return true
    )
  }
})

I am not sure why the error occurs in this case, but if you just need to turn it off - you can add this line under your cy.visit call. The error should not occur again.

Cypress.on('uncaught:exception', (err, runnable) => { return false; })

You're typing is inconsistent - the function is declared to return a Chainable<JQuery<HTMLAllCollection>> but the actual type of the return object is Chainable<HTMLAllCollection>. If you fix this inconsistency, it may resolve your problem.

static get errorMessages(): Cypress.Chainable<JQuery<HTMLAllCollection>> {
    return cy.get<JQuery<HTMLAllCollection>>('app-error');
}

An updated version of Justin Smith's answer that removes the unnecessary callback.

Just to illustrate the readability of Cypress chained commands.

Remove the noise, just use chaining

cy.get('Selector for the anchor tag')      // sets <a> as the subject
  .should('have.attr', 'href')             // changes subject to href attribute
  .should('not.be.empty')                  // now test the href
  .and('contain', 'foo');                  // also test another criteria here

Note, this pattern has nothing to do with Cypress 7, it has been available for many previous versions.

Checking all hrefs

The question actually asks for a way to check all tags on the page.

For example,

<a></a>                      -- should ignore
<a href="/foo"></a>          -- should pass
<a href="/"></a>             -- should pass
<a href=""></a>              -- should fail

One way is to be more selective in the cy.get() by moving the .should("have.attr", "href") predicate inside the element selector.

cy.get("a[href]")                           // get all <a> that have an href
  .each($el => {                            // test individually
    cy.wrap($el.attr('href'), {log:false})  // here we need to cy.wrap
      .should("include", "/")               // because subject needs to change
  })                                      

Cypress log

The type definitions seem to think your alias was of an element.Try adding a type on the parameter to the function passed to .then:

.then((queries:any) => {

You can see your webpack logs by running cypress in debug mode documentation

Mac/Linux

DEBUG=cypress:* cypress run

Windows

set DEBUG=cypress:*
cypress run

It is quite a bit of output, as there's logging from everything cypress does - one of which is cypress:webpack, which can give you the full message.

it('Testing picture uploading', () => {
    cy.fixture('testPicture.png').then(fileContent => {
        cy.get('input[type="file"]').attachFile({
            fileContent: fileContent.toString(),
            fileName: 'testPicture.png',
            mimeType: 'image/png'
        });
    });
});

Use cypress file upload package: https://www.npmjs.com/package/cypress-file-upload

Note: testPicture.png must be in fixture folder of cypress
