Simulate API requests based on sample api data.

This sample JSON file payload-sample.json demonstrates how to structure requests for different HTTP methods, including GET and POST, with placeholders in the URL path that will be replaced with fake data by the script. The headers and body fields are optional and can be used to customize the request headers and body content.

• Create a Virtual Environment and Install python dependencies

python3 -m venv env
source env/bin/activate
pip install -r requirements.txt

• Run simulator with sample payloads.

python3 simulator.py --file payload-sample.json --global_domain https://api.example.com

Arguments

This script accepts several command-line arguments to customize its behavior. Here's a breakdown of each argument:

• --file: Specifies the file containing URLs in JSON format. This file should list the URLs to which requests will be sent. The default value is not set, meaning this argument is required.

• --global_domain: Defines the global domain to prepend to URLs that do not include a domain. This is useful for specifying a base URL for relative paths. The default value is not set. This argument is required if JSON file does not have full domain in the url field.

• --requests_per_minute: Sets the number of requests per minute. This controls the rate at which requests are sent. The default value is 60.

• --duration_minutes: Specifies the duration in minutes for which the script will send requests. The default value is 2 minutes.

• --concurrency: Determines the number of concurrent requests to be made. This can help in managing the load on the server and improving the efficiency of the script. The default value is 1.

To change the number of requests per minute, use the --requests_per_minute argument.

python3 simulator.py --file payload-sample.json --requests_per_minute 20 --global_domain https://api.example.com

To change the duration for which the script will send requests, use the --duration_minutes argument.

python3 simulator.py --file payload-sample.json --duration_minutes 10 --global_domain https://api.example.com

To specify a global domain that will be prepended to URLs without a domain, use the --global_domain argument.

python3 simulator.py --file payload-sample.json --global_domain https://api.example.com

To change the number of concurrent requests, use the --concurrency argument.

python3 simulator.py --file payload-sample.json --concurrency 20 --global_domain https://api.example.com

You can combine multiple arguments to customize the script's behavior according to your needs.

python3 simulator.py --file payload-sample.json --requests_per_minute 30 --duration_minutes 10 --global_domain https://api.example.com --concurrency 20
