fix: fix ui mode / html reporter and coverage integration by hi-ogawa · Pull Request #9626 · vitest-dev/vitest

hi-ogawa · 2026-02-10T10:25:26Z

Description

Closes Coverage page is broken in the html report for @vitest/ui #6945
Closes Support for LCOV Reporter in Vitest UI to Improve Coverage Report Organization #6381
Closes feat(ui): support lcov coverage reporter #9368
Closes Display coverage from a subdir with Vitest UI #3916 (reply in thread) (Deploying html reporter under subpath)
Closes feat: conditional judgment for deleting the "html" reporter #9282

This PR simplifies how coverage HTML is served in UI mode and HTML reporter by introducing a new coverage.htmlDir option.

Before: Coverage HTML serving relied on complex path resolution from coverage.reportsDirectory and the html reporter's subdir option. This required reportsDirectory to be set as a subdirectory of the HTML report directory and also inconsistency between ui mode and html reporting.

After: Coverage HTML is served at a fixed ./coverage subpath relative to the UI base. The new coverage.htmlDir option is automatically inferred from html or lcov coverage reporters, and can be explicitly set for custom coverage providers. This removes the directory layout constraint and makes the integration work reliably across UI mode, HTML reporter, browser mode orchestrator html.

packages/vitest/src/node/core.ts

+      // notify builtin ui and html reporter after coverage html is generated
      for (const reporter of this.reporters) {
-        if (reporter instanceof WebSocketReporter) {
-          reporter.onFinishedReportCoverage()
+        if (
+          'onFinishedReportCoverage' in reporter
+          && typeof reporter.onFinishedReportCoverage === 'function'
+        ) {
+          await reporter.onFinishedReportCoverage()


reportCoverage happens after onTestRunEnd, so now HTML reporter also needs this to be able to collect coverage html.

@AriPerkkio that's why I wanted onCoverage as a separate hook, by the way. We have it, but it's coupled to onTestRunEnd

Current onCoverage doesn't make sense in this case. Here we don't want coverage results / coverage map object. We want to know when coverage reporters have finished.

Related code line: https://github.com/vitest-dev/vitest/blob/731b14440b1b5be60bbfe6e899ec5ad101f87693/packages/ui/node/reporter.ts#L164C36-L164C51

Here is part of my vitest config snippet:

    coverage: {
      enabled: true,
      provider: 'v8',
      reporter: ['text', 'text-summary', 'html'],
      reportsDirectory: './test-report/coverage',
      include: ['src/**/*.ts']
    },
    outputFile: {
      junit: './junit.xml',
      html: './test-report/index.html' <!--- This is not allowed anymore ;(, the html output should sit in a separate directory as the coverage
    },

The coverage.htmlDir is unrelated here. But VItest v4.1.0 broke the coverage report for sure.

I fixed it by changing the outputFile.html, config apparently its not allowed anymore to write to the same directory. as the coverage report.

For others that might have the same issue, I will now use:

    coverage: {
      enabled: true,
      provider: 'v8',
      reporter: ['text', 'text-summary', 'html'],
      reportsDirectory: './coverage',
      include: ['src/**/*.ts']
    },
    outputFile: {
      junit: './junit.xml',
      html: './html/index.html'
    },

@melroy89 this looks like a bug in Vitest, can you raise an issue?

hi-ogawa · 2026-03-16T08:37:14Z

@melroy89 Can you create an issue with repro? I thought I took care of src = dest case, but probably confused myself.

Maybe its not a bug but a feature..?

Since after this PR the output html files, now also contains the coverage directory.. Hence if we point both coverage->reportsDirectory and outputFile->html configs to the same directory, the coverage directory will get copied to the same location.

Hence defining two different directories for either the coverage and the html output fixes the problem.

Repro is as simple as setting both reports to the same directory, called same-directory here in this vitest.config.ts example file.

See also: https://stackblitz.com/edit/vitest-dev-vitest-evwaapxo?file=README.md

And below:

import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    include: ['tests/**/*.test.ts'],
    exclude: ['**node_modules/**', '**.git/**', 'dist', 'build'],
    server: {
      deps: {
        inline: ['@fastify/autoload']
      }
    },
    globals: true,
    reporters: ['default', 'junit', 'html'],
    coverage: {
      enabled: true,
      provider: 'v8',
      reporter: ['text', 'text-summary', 'html'],
      reportsDirectory: './same-directory/coverage',
      include: ['src/**/*.ts']
    },
    outputFile: {
      junit: './same-directory/junit.xml',
      html: './same-directory/index.html'
    },
    environment: 'node',
    bail: 2,
    clearMocks: true
  }
})

reporters: ['default', 'junit', 'html'], ensures it triggers the html report as well.

And the reportsDirectory: './same-dir/coverage' and html: './same-dir/index.html' triggers the "message: 'src and dest cannot be the same'" error.
