[Improve] Don't provide link to global coverage file if it's not found

[edumserrano]

I was wondering if it was possible to NOT show the global code coverage link if the file it points to does NOT exist. I mean this link:

There are two cases where I see this happening:

• The user made a mistake configuring the monocart-reporter code coverage options and the file is pointing to the wrong place. In this case it doesn't matter that much whether the link is there or not as the user expects it to be, it's just incorrect. One could argue that the incorrect link might even help debug the problem.
• The user is producing code coverage reports that are not HTML reports. For instance an lcov only report configured like this:

  
  // playwright.config.ts

export default defineConfig({ testDir: './tests', outputDir: './tests/test-results' ... reporter: [ ... [ 'monocart-reporter', { name: 'playwright code coverage with monocart reporter', outputFile: './tests/test-results/monocart-report.html', ... coverage: { outputDir: './tests/test-results/code-coverage', reports: [ ['lcovonly', { file: 'lcov/code-coverage.lcov.info', // path relative to coverage.outputDir }], ] } } ] ... });

Although being able to see the wrong link when a user misconfigures the code coverage options might be useful I think it's better to just hide so that it provides the correct behaviour when there is no html report being generated.

What do you think @cenfun ?

it should be fixed in version 2.0.1, the report link should not be shown if the link file does not exist. or just set reportPath to empty

coverage: {
          outputDir: './tests/test-results/code-coverage',
          // do not show the global report link
          reportPath: "",
          reports: [...]

I've updated to version 2.0.1 and I can confirm this is now working as expected. Thank you @cenfun 🎉
