This repository contains a k6 load testing script written in TypeScript, designed to dynamically handle payloads, headers, and HTTP methods using environment variables.

• NodeJS v22.5.1

• Cloning the Repository
• Installation
• Running the Script
• Using the .env File
• Notes

To clone this repository, use the following command:

git clone https://github.com/abas/k6-loadtester.git
cd k6-loadtester

1. Ensure you have Node.js and npm installed.

2. Install the necessary packages:

   npm install

   This will install the required TypeScript and k6 packages for development.

3. Install k6 globally if you haven't already:

   npm install -g k6

1. Run the complete build and test process:

   npm test

   This command will:

   • Compile TypeScript files.
   • Copy payloads and headers directories to dist.
   • Run the k6 script with the environment variables specified in the .env file.

2. Alternatively, you can run individual steps:

   • Compile TypeScript:

     npm run build

   • Copy payloads and headers directories:

     npm run postbuild

   • Run the k6 script:

     npm run run:test

The .env file should be located in the root directory of the repository and contains environment-specific variables. Here's an example .env file:

TARGET_URL=https://example.com/api/endpoint
ITERATIONS=10
TARGET_PAYLOAD=./payloads/payload.1.json
TARGET_HEADERS=./headers/headers.json
HTTP_METHOD=POST

• TARGET_URL: The URL to which the request will be sent.
• ITERATIONS: The number of times the request will be sent.
• TARGET_PAYLOAD: The path to the JSON file containing the request payload.
• TARGET_HEADERS: The path to the JSON file containing the custom headers.
• HTTP_METHOD: The HTTP method to use for the request. Supported values are POST, GET, PUT, and DELETE. Defaults to POST if not specified.

• Ensure that the payloads and headers folders exist in the src directory and contain the appropriate files as specified in the .env file.
• The payloads folder should contain JSON files with request payloads.
• The headers folder should contain JSON files with custom headers.
• The HTTP_METHOD variable allows you to specify the request method dynamically.

Feel free to customize the .env file according to your testing needs.
