= bench-runner
TIP: http://www.benchmarkjs.com[benchmark.js] runner for Node.js like
http://mochajs.org/[mocha].
== Getting Started
Install with `npm`:
[source, bash]
$ npm install bench-runner -g
$ mkdir benches
$ $EDITOR benches/string.js #open with your favorite editor
In your editor:
[source,javascript]
suite( 'find in string', () => {
bench( 'RegExp#test', () => /o/.test( 'Hello World!' ) );
bench( 'String#indexOf', () => 'Hello World!'.indexOf( 'o' ) > -1 );
bench( 'String#match', () => !!'Hello World!'.match( /o/ ) );
} );
Back in the terminal:
[source,bash]
$ bench-runner -f fastest
[find in string]
RegExp#test x 11,841,755 ops/sec ±3.00% (89 runs sampled)
String#indexOf x 30,491,086 ops/sec ±0.45% (92 runs sampled)
String#match x 8,287,739 ops/sec ±2.57% (88 runs sampled)
fastest: String#indexOf
== Suites & Benchmarks
Group benchmarks in a suite:
[source,javascript]
----
suite( 'group of tests', () => {
bench( 'a benchmark', ...);
bench( 'yet a benchmark', ...);
} );
----
=== Paths
Suites and benchmarks are assigned paths which are useful, for example, for filtering with the `grep`
option. Paths are constructed by concatenating the names of suites and benchmarks leading to the
target, separated with a colon `:`. In the above snippet, benchmark `a benchmark` has the
path `:group of tests:a benchmark`
=== Nested Suites & Benchmarks
Suites can be nested:
[source,javascript]
----
suite( 'es5 vs es6', () => {
suite( 'classes', () => {
function ES5() { this.foo = 'bar'; }
ES5.prototype.bar = function () { };
class ES6 {
constructor() { this.foo = 'bar'; }
bar() { }
}
bench( 'es5', () => new ES5());
bench( 'es6', () => new ES6());
} );
suite( 'arrow functions', () => {
var es5obj = {
value : 42,
fn : function () { return function () { return es5obj.value; }; }
};
var es5fn = es5obj.fn();
var es6obj = {
value : 42,
fn : function () { return () => this.value; }
};
var es6fn = es6obj.fn();
bench( 'es5', es5fn );
bench( 'es6', es6fn );
} );
} );
----
Output:
[source,bash]
----
$ bench-runner -g es5
[es5 vs es6]
[arrow functions]
es5 x 79,383,329 ops/sec ±0.95% (89 runs sampled)
es6 x 80,249,618 ops/sec ±1.21% (83 runs sampled)
[classes]
es5 x 70,144,602 ops/sec ±0.41% (91 runs sampled)
es6 x 36,864,672 ops/sec ±1.27% (87 runs sampled)
----
=== Benchmarking Asynchronous Functions
To defer a benchmark, pass an callback argument to the benchmark
function. The callback must be called to end the benchmark.
[source,javascript]
----
suite('deferred', () => {
bench('timeout', (done) => setTimeout(done, 100));
});
----
Output:
[source,bash]
....
[deferred]
timeout x 9.72 ops/sec ±0.41% (49 runs sampled)
....
=== Dynamically Generating Benchmarks
Use javascript to generate benchmarks or suites dynamically:
[source,javascript]
----
suite( 'buffer allocation', () => {
for ( let size = minSize; size <= maxSize; size *= 2 ) {
bench( size, () => Buffer.allocUnsafe( size ) );
}
} )
----
The above code will produce a suite with multiple benchmarks:
[source,bash]
----
[buffer allocation]
1024 x 2,958,389 ops/sec ±2.85% (81 runs sampled)
2048 x 1,138,591 ops/sec ±2.42% (52 runs sampled)
4096 x 462,223 ops/sec ±2.48% (54 runs sampled)
8192 x 324,956 ops/sec ±1.56% (44 runs sampled)
16384 x 199,686 ops/sec ±0.94% (80 runs sampled)
----
== Usage
Run `bench-runner` from the command line. By default, `bench-runner`
looks for `*.js` files under the `benches/` subdirectory.
[source,bash]
----
$ bench-runner [options] [files]
Options:
-f, --filter Report filtered (e.g. fastest) benchmark after suite runs
[choices: "fastest", "slowest", "successful"]
-d, --delay The delay between test cycles (secs) [number]
-x, --maxTime The maximum time a benchmark is allowed to run before
finishing (secs) [number]
-s, --minSamples The minimum sample size required to perform statistical
analysis [number]
-n, --minTime The time needed to reduce the percent uncertainty of
measurement to 1% (secs) [number]
-g, --grep Run only tests matching <pattern> [string]
-p, --platform Print platform information [boolean]
-t, --test Do a dry run without executing benchmarks [boolean]
--help Show help [boolean]
-r, --recursive [boolean] [default: false]
----
**-R, -reporter <name>** +
The --reporter option allows you to specify the reporter that will be used, defaulting to "console". You may also use third-party reporters installed with `npm install`.
**-g, --grep <pattern>** +
The --grep option will trigger `bench-runner` to only run tests
whose paths match the given pattern which is internally compiled to a `RegExp`.
In the snippet below:
* "es5" will match only `:compare:classes:es5` and `:compare:arrow functions:es5`,
* "arrow" will match `:compare:arrow functions:es5` and `:compare:arrow functions:es6`
[source,javascript]
----
suite( 'compare', () => {
suite( 'classes', () => {
bench( 'es5', () => new ES5());
bench( 'es6', () => new ES6());
} );
suite( 'arrow functions', () => {
bench( 'es5', es5fn );
bench( 'es6', es6fn );
} );
} );
----
**-t, --test** +
Enables dry-run mode which cycles through the suites and benchmarks selected by
other settings such as `grep` without actually executing the benchmark code.
This mode can be useful to verify the selection by a particular grep filter.
**--delay, --maxTime, --minSamples, --minTime** +
These options are passed directly to `benchmark.js`
== Hooks
Hooks must be synchronous since they are called by `benchmark.js` which
does not support async hooks at this time. Also, `setup` and`teardown`
are compiled into the test function. Including either may place
restrictions on the scoping/availability of variables in the test
function (see `benchmark.js` docs for more information).
[source,javascript]
----
suite('hooks', function() {
before(function() {
// runs before all tests in this suite
});
after(function() {
// runs after all tests in this suite
});
beforeEach(function() {
// runs before each benchmark test function in this suite
});
afterEach(function() {
// runs after each benchmark test function in this suite
});
bench('name', {setup: function(){
//setup is compiled into the test function and runs before each cycle of the test
}})
bench('name', {teardown: function(){
//teardown is compiled into the test function and runs after each cycle of the test
}}, testFn)
//benchmarks here...
});
----
== Reporters
=== console
The default reporter. Pretty prints results via `console.log`.
=== json
Outputs a single large JSON object when the tests have completed.
