Give a concise argument for testing public behavior.
Test public behavior because it’s the contract users depend on. If tests target internals, they become brittle: harmless refactors break tests even when the software still works. By testing observable inputs/outputs and side effects, you verify real correctness while preserving freedom to change the implementation.
Fill the inputs the node publishes and run it on your own account. The same ports, defaults and types the studio uses.
Fill in the inputs and run the node to see its output here.
The same node, called by id from any surface. Every tab pins this node and passes the ports below.
