Get elements by data attribute by creating a Cy command on the fly
According to the Cypress best practices for Selecting Elements using dedicated test id data attributes is the most stable way of finding elements during end-to-end tests. Yet typing the full selector is ... annoying.
<div data-test-id="foo">foo</div>cy.get('[data-test-id="foo"]').should('have.text', 'foo')Who has time for this!
So you could make a little utility function
const tid = s => `[data-test-id="${s}"]`
cy.get(tid('foo')).should('have.text', 'foo')Hmm, sure, but what if your HTML markup has different data attributes? Like this
<div data-test-id="foo">foo</div>
<div data-test="bar">bar</div>
<div test-id="baz">baz</div>Do you need to write 3 different helper functions? No. With cypress-get-it you can create data attribute selector methods with descriptive names. In fact, the actual selector will be created from the method name on the fly. You want to get element with data-test-id=foo? Just use camel cased words and call cy.getDataTestId('foo'). The above elements become
cy.getDataTestId('foo').should('have.text', 'foo')
cy.getDataTest('bar').should('have.text', 'bar')
cy.getTestId('baz').should('have.text', 'baz')
So any element attribute like foo-bar-baz="something" could be fetched with descriptive cy.getFooBarBaz("something").
Load this plugin from your support file and it will replace global cy instance with an ES6 Proxy which will intercept any methods calls to get... and will call cy.get with the right selector automatically.
