Test Vector

This library is inspired by the talk Integrated Tests Are A Scam.

API

Memoizes the callback function so that it will record its inputs and outputs.

Returns

• memoized: the memoized callback function
• vector: an AsyncIterable recording of the callback function's inputs and outputs

mockCaller (vector, callback)

Calls the callback function repeatedly with inputs from vector while making sure the outputs match expectations.

Returns

a promise that resolves when complete

mockFunction (vector)

Creates a mock function from a test vector recording. vector is an AsyncIterable.

Returns

• mock: a new function that behaves like an earlier memoized function based on the given vector
• status: a promise that resolves when the last output from vector is returned by mock
