Does anyone know a working solution for Cypress + Cucumber tags + Spec tags?

[morganizeit]

I have my Cypress project setup so that I can write and run both Spec and Cucumber tests in one go.

cypress run --spec "cypress/tests/gsac/specs/*.cy.js,cypress/tests/gsac/*.feature"
Works great! All test results in one report.

But now I need to filter what I run. Filtering by test name is not flexible enough. Cucumber has excellent tagging features using AND/OR expressions to filter by tags.

// Feature files
@smoke
Feature: A critical thing
  @slow
  Scenario: A thing that is slow to test.

@smoke
Feature: A critical thing

# Run syntax
cypress run --spec "cypress/tests/integration/*.cy.js,cypress/tests/integration/*.feature" \
--env tags='@smoke and not @slow'

I can use the filterSpecsMixedMode option to either include or exclude all Spec tests, but I can't filter them with Cucumber tags.

I've researched various libraries for filtering Specs but I haven't found one that is fully compatible with cypress-cucumber-preprocessor.

• cypress-tags - Not compatible. Throws an exception for any tag on a Feature or Scenario. That's too bad b/c it supports tag expressions similar to Cucumber.
• cypress-cucumber-tagging - Not compatible. When installed, all Cucumber tests are skipped. Also supports Cucumber tag expressions, argh.
• cypress-grep - This is the closest I've gotten but it is not fully compatible. For a given test run you can use tags='' for Cucumber OR grepTags='' for Spec but not both. If both env vars are set then all Cucumber tests are skipped.

The lack of a solution forces me separate builds/reports for Spec vs Cuke which I really don't want to do.
