Proposal: add custom Test Context to HTML report

[antoniogiurini]

Hi,
In my k6 tests I needed to include 4-5 contextual variables in the generated HTML report, for example:

• environment name
• test profile
• test file or scenario name

I implemented a small local change that adds an optional summaryVars option to htmlReport(data, opts), rendered as a simple Test Context table near the top of the default HTML report.

Example usage:

htmlReport(data, {
  title: 'Custom Test Report',
  summaryVars: [
    { name: 'Environment', value: __ENV.ENVIRONMENT },
    { name: 'Profile', value: __ENV.PROFILE },
  ],
})

It seems to me that this is a fairly common scenario for tests that are data driven.
Are you interested in integrating this feature?
