  Vitest.mergePreset({
    ssr: {
      resolve: {
        conditions: ['@seek/my-service/source'],
      },
    },
    test: {
      env: {
        ENVIRONMENT: 'test',
      },
      coverage: {
        thresholds: {
          branches: 100,
          functions: 100,
          lines: 100,
          statements: 100,
        },
        exclude: ['src/other-test-utils'],
