Lighthouse-ci: Ability to match exact URLs in assertMatrix

[kunalnagar]

We would like to assert for exact URLs in the assertMatrix but noticed that the underlying logic matches the RegEx using an AND logic. Here is a trimmed down version of our config:

const budgets = [
  {
    page: '/',
    assertionScore: {
      performance: 0.8,
      accessibility: 0.9,
      'best-practices': 0.7,
      seo: 0.9,
    },
    page: '/some-page',
    assertionScore: {
      performance: 0.7,
      accessibility: 0.9,
      'best-practices': 0.7,
      seo: 0.9,
    },
  },
  // ... more budgets here based on page
]

module.exports = {
  ci: {
    collect: {
      numberOfRuns: 2,
      url: [
        'http://localhost:3000/',
        'http://localhost:3000/some-page',
        'http://localhost:3000/some-other-page',
      ],
      startServerCommand: 'npm start',
    },
    assert: {
      assertMatrix: budgets.map(budget => ({
        matchingUrlPattern: `http://localhost:3000${budget.page}`,
        assertions: {},
      })),
    },
    upload: {
      target: 'temporary-public-storage',
    },
  },
}

When the CI runs, it runs the first budget / for all the URLs (because of RegEx matching). We want the respective budget to be run for the specific URL only.

Is there a way of specifying exact URLs and running assertions only for those?

It's a regex so

  matchingUrlPattern: `http://localhost:3000${budget.page}$`

should work :)

@patrickhulce makes sense, thank you that worked brilliantly! Closing this.
