transform-stream-test
Install
npm install transform-stream-test
What
A module that leverages tape to test a transform stream. Transform streams typically take a set of input chunks and deterministically pipes out chunks generated from the input.
transform-stream-test
lets you easily create test cases(via tape) where you provide input and assert that you get the output you expect.
Example
var test = ;var through = ;var tst = ; ;
Methods
You create a fixture by calling tst with a tape test object and the transform stream to test.
var fixture = t transformStream;
fixture.deepEqual(input, output, msg, cb, timeout)
Performs a deep equal comparing each output chunk received with each expected output chunk.
input
: Array of input chunksoutput
: Array of expected output chunksmsg
: The description of the test casecb
: function fired withcb(success, msg)
success
is a boolean representing whether or not the output matched the expectationmsg
is the same message provided above
timeout
: optional number of milliseconds to finish the test case- This is useful for when you don't expect any output
