Cobertura and lcov reporters not found

[DerGernTod]

hi folks! i did a bit of research and found lots of occasions where people use "cobertura" and "lcov" as if they were built-in reporters (see here or here). i couldn't find any reference to them in any vitest repos, and if i use them locally i get

Error: Failed to load url cobertura (resolved id: cobertura). Does the file exist?

if i look into node_modules/vitest, i can find this interface:

interface ReportOptions {
    clover: CloverOptions;
    cobertura: CoberturaOptions;
    "html-spa": HtmlSpaOptions;
    html: HtmlOptions;
    json: JsonOptions;
    "json-summary": JsonSummaryOptions;
    lcov: LcovOptions;
    lcovonly: LcovOnlyOptions;
    none: never;
    teamcity: TeamcityOptions;
    text: TextOptions;
    "text-lcov": TextLcovOptions;
    "text-summary": TextSummaryOptions;
}

which makes it even more confusing for me.

i also couldn't find an npm package or anything similar. am i blind? what am i missing?

Coverage reporters are specified in coverage.reporter, not reporters:

export default defineConfig({
  test: {
-   reporters: ['lcov'],
+   coverage: {
+     reporter: ['lcov'],
+   },
  },
})
