    Generate a CPU profile of your Mocha test suite execution

    Overview

    This Mocha hook allows you to generate a V8 CPU profile of your test suite's execution. The profiling starts immediately before the first test is run and ends immediately after all tests run. This is accomplished using Mocha's beforeAll() and afterAll() hooks.

    The benefits of doing this are that the CPU profile will not include functions which get only executed during your application's startup or, even worse, on-the-fly source code compilation.

    Installation

    1. Install the package: npm i -D mocha-profiler
    2. Add the package to your .mocharc.js configuration file:
    module.exports = {
     require: [
       'mocha-explorer',
     ],
    }

    Usage

    1. Run your test suite
    2. A file is generated in your current working directory

    VS Code
