Questions tagged [lab]

Lab is a simple test utility for node.

Unlike other test utilities, lab uses domains instead of uncaught exception and other global manipulation. Our goal with lab is to keep the execution engine as simple as possible, and not try to build an extensible framework. lab works with any assertion library that throws an error when a condition isn't met.
