@flakiness/junit-xml

Convert JUnit XML test reports into a Flakiness report and upload it to flakiness.io.

The recommended way to run it is with npx (no install step):

npx @flakiness/junit-xml --flakiness-project myorg/myproject ./build/reports/junit 

This combines every XML file under the given path into a single Flakiness report and auto-uploads it to flakiness.io. See authentication on how to configure auto-upload.

If your environment has no Node.js, a standalone binary is also available.

Usage

flakiness-junit-xml [options] <junit-path>

  <junit-path>                   JUnit XML file, or a directory of XML files (scanned recursively)
  --env-name <name>              Environment name (defaults to --category, or `junit`)
  --commit-id <id>               Git commit ID (auto-detected from cwd if omitted)
  --title <title>                Report title (env: FLAKINESS_TITLE)
  --output-dir <dir>             Output directory (default: flakiness-report)
  -c, --category <category>      Category, e.g. `bun`, `rust` (default: `junit`)
  --flakiness-project <project>  Flakiness project, `org/project` (env: FLAKINESS_PROJECT)
  --token <token>                Flakiness.io access token (env: FLAKINESS_ACCESS_TOKEN)
  --endpoint <url>               Flakiness.io API endpoint override
  --disable-upload               Convert only; don't upload (env: FLAKINESS_DISABLE_UPLOAD)

Requires Node.js ^20.17.0 || >=22.9.0.

flakiness-junit-xml ingests JUnit XML from any test runner. Some runners don't emit it by default — the examples below show how to get XML out of the common ones.

Example: ingesting bun test results

bun test emits JUnit XML with --reporter=junit:

bun test --reporter=junit --reporter-outfile=./junit.xml
npx @flakiness/junit-xml --category bun --flakiness-project myorg/myproject ./junit.xml

Example: ingesting Rust cargo-nextest results

cargo test doesn't emit JUnit XML; cargo-nextest does. Add a CI profile in .config/nextest.toml:

[profile.ci.junit]
path = "junit.xml"

Then run the tests and point at the XML nextest writes under target/nextest/:

cargo nextest run --profile ci
npx @flakiness/junit-xml --category rust --flakiness-project myorg/myproject ./target/nextest/ci/junit.xml

Standalone binary (no Node.js)

This tool is also shipped as a single self-contained executable that bundles its own runtime, so it works on machines without Node.js.

macOS / Linux:

curl -fsSL https://github.com/flakiness/junit-xml/releases/latest/download/install.sh | sh

Windows (PowerShell):

irm https://github.com/flakiness/junit-xml/releases/latest/download/install.ps1 | iex

This installs a flakiness-junit-xml command on your PATH. Then use it exactly as above:

flakiness-junit-xml --flakiness-project myorg/myproject ./build/reports/junit 

Note

You can set INSTALL_DIR to configure custom location for installation.

curl -fsSL https://github.com/flakiness/junit-xml/releases/latest/download/install.sh | INSTALL_DIR="$HOME/.local/bin" sh

Authentication

The report is uploaded to flakiness.io automatically. Authentication, in priority order:

1. Access token — --token or FLAKINESS_ACCESS_TOKEN.

2. GitHub Actions OIDC — no token needed when --flakiness-project (or FLAKINESS_PROJECT) is set, the project is bound to the repository, and the workflow grants id-token: write.

3. GitLab CI/CD OIDC — no token needed when --flakiness-project (or FLAKINESS_PROJECT) is set and the project is bound to the GitLab project. GitLab mints ID tokens at job start, so the job must declare one named FLAKINESS_ID_TOKEN whose audience matches the project:

   test:
     id_tokens:
       FLAKINESS_ID_TOKEN:
         aud: my-org/my-project   # must match --flakiness-project
     script:
       - npx @flakiness/junit-xml --flakiness-project my-org/my-project ./junit.xml

To convert without uploading, pass --disable-upload or set FLAKINESS_DISABLE_UPLOAD=1. The report is still written to --output-dir.
