@dagger.io/vitest

Vitest reporter with OpenTelemetry support for auto-instrumentation with Dagger.

Installation

With Dagger

dagger toolchain install github.com/dagger/vitest

# Execute vitest through the toolchain (no additional setup needed)
dagger check

You can customize vitest using customization

As a library

If you prefer to directly install the vitest library, run:

npm install --save-dev @dagger.io/vitest

Then set the import in your NODE_OPTIONS when executing your tests:

NODE_OPTIONS="$NODE_OPTIONS --import @dagger.io/vitest/register" npx vitest run

That's it! The reporter will automatically create OpenTelemetry spans for:

• Test files (modules)
• Test suites (describe blocks)
• Individual tests (it/test blocks)

Span Attributes

Test spans include dagger.io/ui.boundary plus OpenTelemetry test semantic convention attributes: test.case.name, test.case.result.status, and test.suite.name.

Suite spans include dagger.io/ui.boundary, test.suite.name, and test.suite.run.status.

Span Hierarchy

test-file.ts (module span)
  └─ describe block (suite span)
      ├─ test 1 (test span)
        ├─ SELECT * FROM users (inside test span)
        └─ Container.withExec(...) (inside test span)
      └─ test 2 (test span)
