Benchmartian allows you to run your incredible [benchmark.js][http://benchmarkjs.com] benchmarks from the command line much like you would any other test suite such as
Install from npm.
$ npm install -g benchmartian
And to run benchmarks:
$ benchmartian Benchmarking benchmarks/benchmarks.js.. .. Completed file benchmarks/benchmarks.js. Results -> benchmarks/benchmarks.js RegExp#test x 15,634,369 ops/sec ±0.96% (94 runs sampled) String#indexOf x 25,131,771 ops/sec ±0.97% (95 runs sampled)
Benchmartian will take an array of files as arguments or if no arguments are given,
benchmartian will look in
benchmark/ directory of current working directory. You can also supply a reporter which will define how the test results are outputted. To see a list of reporters do
benchmartian -- Run benchmark.js benchmarks from the CLI. Usage: benchmartian [files] Begin benchmarking. If no are files supplied, benchmartian looks in `benchmark/`. --reporter [reported] Select a reporter from /reporters. Defaults to basic. --reporters Print out available reporters. --help Print this help.
To make defining benchmarks incredibly simple,
benchmartian exposes all methods on the
benchmark.Suite prototype into the global scope which allows for concise definitions. The only function
benchmartian calls (if it hasn't already been called with your own options) is
suite.run. The reporters take care of handling the output so you can sit back and focus on your benchmarks.
Example from the benchmarkjs.com homepage.
Example defining your own
;;optionsmaxTime = 3; // Second
benchmark.Suite is exposed, you can configure how the benchmarks are run by supplying options to the
run function or set them on the global
options variable. For the options documentation, see here.
benchmartian are made incredibly easy by the
reporters/ directory and require the
index.js file. See
reporter/basic.js for an example.
var reporter = ;
The reporter's job is to handle different events emitted by
benchmartian and a
benchmark.Suite on a suite.
benchmartian emits 3 events:
(files)as an argument.
(filename, suite). It's in this callback where you define your
(results). Results is a key value store of
filename: suiteso you can compile a comphrensive report.
Finally, export your reporter:
moduleexports = reporter;
Thanks to the authors of the incredible benchmark.js library.
benchmartian owes it's existance to it.
