cypress/grep issue using Typescript

[avi-ran]

Hi everyone :)

I am currently trying to use cypress/grep plugin to efficiently filter my test cases.
Currently I am using a Typescript config on my cypress porject.

I tried to set up my project in order to use cypress/grep but with no success for instance...
I am following these instructions: https://github.com/cypress-io/cypress/tree/develop/npm/grep#install

I let you see my config using this minimal repro: https://github.com/avi-ran/cypress-grep-ts-issue/tree/main

I suspect this config to be wrong in cypress/support/e2e.ts (as I don't see any registerCypressGrep exported in the plugin code).

// "import" with `@ts-ignore`
// @see error 2306 https://github.com/microsoft/TypeScript/blob/3fcd1b51a1e6b16d007b368229af03455c7d5794/src/compiler/diagnosticMessages.json#L1635
// @ts-ignore
import registerCypressGrep from '@cypress/grep'
registerCypressGrep()

Let me know if there are any other mistake done on my config.

Current behaviour on my minimal repro:

• Two tests are run even if only one mentione 'config' tag

DEBUG=@cypress/grep npx cypress run --env grepTags=config

===============
  Running:  test_cases.cy.ts                                                               


  Dummy tests
    ✓ works as an array (20ms)
    ✓ works as a string (9ms)

Expected behavior on my minimal repro:

• Only the test with tag 'config' is run

DEBUG=@cypress/grep npx cypress run --env grepTags=config

===============
  Running:  test_cases.cy.ts                                                               


  Dummy tests

Have a nice day!
Kind regards,
