Install via npm:

    $ npm install -g puppeteer-loadtest

## Usage

To run a basic load test, just supply the name of a puppeteer script to run:

    $ puppeteer-loadtest --file=sample.js

This will run the specified puppeteer script once in chrome headless instance.

### Parameters

`--s` flag is to mention sample size
`--c` flag is to mention number of concurrent executions per sample
`--silent` boolean to enable or disable logs
`--outputFile` send performance results to output file

    $ puppeteer-loadtest --s=100 --c=25 --file=sample.js
    
This will run a total of 100 runs through the specified puppeteer script across 25 concurrent chrome headless instances.


### Examples

    $ puppeteer-loadtest --file=sample.js
    
    $ puppeteer-loadtest --file=./test/sample.js  --s=100 --c=25
    
    $ puppeteer-loadtest --file=./test/sample.js  --s=100 --c=25 --silent=true
    
    $ puppeteer-loadtest --file=./test/sample.js  -s 100 -c 25

    $ puppeteer-loadtest --file=./test/sample.js  -s 100 -c 25 --outputFile=performance.json


### use as node module 

    ```
    const startPuppeteerLoadTest = require('puppeteer-loadtest');
    const results = await startPuppeteerLoadTest({
        file, // path to file
        samplesRequested, // number of samples requested
        concurrencyRequested, // number of concurrency requested
    });
    console.log(results);
    ```
