lambda-mocha-runner v1.0.1

#Mocha Lambda Runner Easily run mocha tests programmatically from a lambda. This makes running integration tests from an AWS Lambda very simple.

Install

npm install lambda-mocha-runner

Contract

Runner.run takes two parameters: 1. mochaOptions - This gets passed directly into Mocha. For More Information. 2. testDir - The path to the directory with your tests. This should be relative to the root directory of your lambda.

Example

const Runner = require("lambda-mocha-runner");

class Lambda {
  static run(event, context, callback) {
    const context = { mochaOptions: {}, testDir: "path/to/test/files" };
    
    Runner.run(context)
      .then((response) => callback(null, response))
      .catch((err) => callback(err));
  }
}

module.exports = Lambda;
