           "--shared"
           ;;Needed for correct snapshot checksums
           "--v8-enable-snapshot-compression")

Run make test-ci-js to run the test suite.

How often does it reproduce? Is there a required condition?

Always.

What is the expected behavior? Why is that the expected behavior?

All tests should pass. If some dependency (test or otherwise) needs to be built for a test, the build system should take care of it automatically.

What do you see instead?
