Benchmark conditions
This benchmark measures execution time for every combination of following conditions:
1. Test types
- Synchronous empty test:
function () {} - Synchronous heavy test:
function () { for (let i = 0; i < 10000; i++) { new Date(); } } - Asynchronous empty test with zero delay:
function (done) { setTimeout(done, 0); } - Asynchronous empty test with random delay:
function (done) { setTimeout(done, Math.round(Math.random() * 10)); }
2. Tests structure
- With nested suites
- Without nested suites
3. Run types
- With Babel transpiling
- Without Babel transpiling

Clone the repo:
git clone https://github.com/vitalets/js-testrunners-bench.git -
Install dependencies:
cd js-testrunners-bench npm install -
Generate tests:
node unit genAfter run check that
/testsdirectory is created and filled with test-files. -
Run benchmark:
node unit run [testsType] [runType]Examples:
# Synchronous empty tests without nested suites and without Babel node unit run test=syncEmptyFn_nestedSuites=false babel=false # Asynchronous tests with random delay 0-10ms with nested suites and Babel node unit run test=asyncEmptyFnRandomDelay_nestedSuites=true babel=true etc..
Example output:
> node unit run test=syncEmptyFn_nestedSuites=false babel=false
