Performance testing library

METATEST is a library for testing the execution time of functions and comparing functions by speed.

Features

• Tests synchronous and asynchronous functions
• Detects anomalies of testing and filters them out
• Compares functions by execution time
• Can run optimizing iterations before testing
• Tests each function in a separate process
• Test each function sequentially
• Gets optimization status of test function

Speed test

metatest.speed(caption, fns, [, options])

• caption - test caption
• fns - array of test functions
• options - test options(optional)
  • count - number of test iterations
  • startCount - number of first optimizing iterations
  • anomalyPercent - maximum possible percent of anomalies

Example:

metatest.speed('Benchmark example',
  [f1, f2, f3, [f4, f5]], {
    count: 250000,
    anomalyPercent: 5,
    startCount: 0
});

• Synchronous test functions: f1, f2, f3
• Asynchronous test functions(callback-last / err-first function): f4, f5
