Vitest coverage is not generating coverage summary even with json-summary reporter set.

Hi all,

Vitest coverage run is not generating coverage summary even with json-summary reporter set. Below is my vitest config.

import path from 'path';

import { defineConfig } from 'vitest/config';

export default defineConfig({
  test: {
    alias: {
      '@': path.resolve(__dirname, './src'),
      '@test': path.resolve(__dirname, './test'),
    },
    reporters: ['default'],
    coverage: {
      provider: 'v8',
      reporter: ['text', 'json-summary', 'json'],
      reportOnFailure: true,
    },
    setupFiles: ['./test/setup/custom_matchers.ts']
  },
});

When I check the coverage directory, it only generates the coverage-final.json. I was hoping to see coverage-summary.json somewhere but there is none.

$ ls
base.css             coverage-final.json  prettify.css           sorter.js
block-navigation.js  favicon.png          prettify.js            src
clover.xml           index.html           sort-arrow-sprite.png

Works fine here: https://stackblitz.com/~/edit/vitest-dev-vitest-jsxeft9m?file=vite.config.ts

Yeah I can see - It is very weird :( May be because I am using the workspace? The workspace config is defined as follows

import { defineWorkspace } from 'vitest/config';

export default defineWorkspace([
  {
    extends: './vitest.base-config.ts',
    test: {
      name: 'db-e2e',
      include: ['test/database/**/*.db.test.ts'],
      pool: 'threads',
      poolOptions: { threads: { singleThread: true } },
      env: {
        VITEST_TEST_TYPE: 'db-e2e',
      },
    },
  },
  {
    extends: './vitest.base-config.ts',
    test: {
      name: 'unit',
      include: ['test/unit/**/*.test.ts'],
      env: {
        VITEST_TEST_TYPE: 'db-parallel',
      },
    },
  },
  {
    extends: './vitest.base-config.ts',
    test: {
      name: 'db-parallel',
      include: ['test/database_parallel/**/*.test.ts'],
      globalSetup: ['test/global-setup.ts'],
      env: {
        VITEST_TEST_TYPE: 'unit',
      },
    },
  },
]);

Make sure you have the coverage options in vitest.config.ts, not in the vitest.base-config.ts that those projects extend.

Thank you @AriPerkkio it works now.
