Custom Command is not a function

[yurakhomitsky]

Current behavior

I was following along with the installation instructions from cypress/schematic for "ng new" project

Then I decided to add a custom command however cypress throws the error: "cy.login is not a function"

• To add a custom command I wrote the following code in the commands.ts file
  Cypress.Commands.add("login", () => { cy.log('login...') })

• Added it to the namespace
  declare namespace Cypress { interface Chainable<Subject = any> { login(): any; } }

• Uncommented this line import './commands'; in the e2e.ts file

• Used cy.login() in the spec.cy.ts file

Desired behavior

Cypress should not throw the error "cy.login is not a function"

@yurakhomitsky thanks for the example project. I see in your Cypress configuration that you have supportFile: false for e2e

  e2e: {
    baseUrl: 'http://localhost:4200',
    supportFile: false
  }

Setting this option to false means that cypress/support/e2e.ts will not be executed when you launch e2e testing. Because of this, commands.ts is never imported, and your custom commands are never registered.

If you remove supportFile: false, you should be able to call your custom commands successfully.

I'm going to route this to the tools team to see if we should remove supportFile: false from the Cypress configuration that we generate with cypress-schematic to avoid confusion.

I don't have "supportFile: false" in my e2e but still my custom commands are not working.

Hi @Amit-P , sorry you're having trouble. This issue has been closed for some time. If you're experiencing an issue that you believe is a Cypress bug I would recommend you open a new issue and provide all the requested information including a reproducible example (ideally a git repository we can clone and run ourselves) and Debug Logs.

Since this sort of issue is usually a configuration or setup issue (rather than a bug in Cypress) you may want to reach out on Discord for help.

having supportFile correctly set, custom commands don't work in 12.17.4 anymore.

@vecernik please open a new issue with a reproducible example and the Cypress team will be happy to investigate.
