Testing End-to-End (E2E)

This section describes how developers will test codebase related to the e2e tests.

Testing stack

All of our UI tests MUST be done using Cypress as the main testing frameworks with Synpress for wallet support. The test's code MUST be written using Typescript and ran using ts-jest to have type checking support.

Directory structure

New tests MUST be placed in a tests/e2e directory, in the root path. The files will be named as the flow that they will be testing, that is, if the e2e tests file will be testing the Collection Publication flow, the name of the file MUST be collection-publication.spec.cy.ts.

How frequent they will run

Scheduled via GitHub Actions. Frequency TBD.

What to test

• Most relevant user interactions in the dApps (Items Publications, NFTs Purchases, etc.)

How to test

All of our tests MUST follow the semi-structured style of Given-When-Then (GWT).

The following example:

1. Given a user visits https://example.cypress.io
2. When they click the link labeled type
3. And they type "fake@email.com" into the [data-testid="action-email"] input
4. Then the URL should include /commands/actions
5. And the [data-testid="action-email"] input has "fake@email.com" as its value

Should be written as:

describe('Given a user visits https://example.cypress.io', () => {
  beforeEach(() => {
    cy.visit('https://example.cypress.io')
  })

  describe('when clicks the link labeled type', () => {
    beforeEach(() => {
      cy.contains('type').click()
    })

    describe('and type an email into the action-email input', () => {
      beforeEach(() => {
        // Get an input, type into it
        cy.get('.action-email').type('fake@email.com')
      })

      it('Then the url should include /commands/actions', () => {
        // Should be on a new URL which
        // includes '/commands/actions'
        cy.url().should('include', '/commands/actions')
      })

      it('and the action-email input value should contain the typed email', () => {
        //  Verify that the value has been updated
        cy.get('.action-email').should('have.value', 'fake@email.com')
      })
    })
  })
})
