New: add getPhysicalFilename() method to rule context (fixes #11989) - #14616

Thanks for contributing!

I find physicalFilename is not available in ValidTestCase, so it makes testing cases for virtual filename unavailable, should that be supported?

Before context.getPhysicalFilename, I have a custom util getPhysicalFilename and a test case like:

ruleTester.run('remark', remark, {
  valid: [
    {
      code: '<header>Header2</header>',
      parser,
      parserOptions,
      filename: path.resolve(__filename, '0-fake.mdx'), // virtual filename
    },
  ],
})

But when I migrate to context.getPhysicalFilename, it results context.getPhysicalFilename() === filename, it is not correct, so maybe a new physicalFilename option is required for this case:

ruleTester.run('remark', remark, {
  valid: [
    {
      code: '<header>Header2</header>',
      parser,
      parserOptions,
      physicalFilename: __filename,
      filename: path.resolve(__filename, '0-fake.mdx'), // virtual filename
    },
  ],
})

@JounQin I'd guess we'll want to do that. Can you open an issue? People aren't as likely to see things that are part of finished discussions.
