If it's your first time building, you'll need to run yarn build.

Then to run test cases across all packages run yarn test from the root directory.

Note: to ensure that tests from a downstream in-repo dependency are running against the latest upstream version of code, you'll have to run yarn build every time you change the upstream dependency.

The dependency flow is as follows:

• @foxglove/omgidl-serialization depends on @foxglove/omgidl-parser
• @foxglove/ros2idl-parser depends on @foxglove/omgidl-parser

1. Open a PR updating the version of the packages that have new versions that need to be deployed.
2. Land PR with change of version numbers and pull the latest on main locally
3. Add git tags for each package you'd like to publish using the following prefixes
   • @foxglove/omgidl-parser -> omgidl-parser/vX.X.X
   • @foxglove/omgidl-serialization -> omgidl-serialization/vX.X.X
   • @foxglove/ros2idl-parser -> ros2idl-parser/vX.X.X
4. For example: if you're updating @foxglove/omgidl-parser to v1.2.1 you would add the corresponding git tag by running git tag omgidl-parser/v1.2.1. For updating multiple packages on a single commit you can add multiple tags: git tag omgidl-parser/v1.2.1 omgidl-serialization/v1.1.3 .
5. After adding the tag run git push origin refs/tags/<tag> to push the specific tag to the remote
