Objective: Create a CLI system in Go to perform load testing on a web service.

The user should provide the following parameters via CLI:

• --url: URL of the service to be tested.
• --requests: Total number of requests.
• --concurrency: Number of simultaneous calls.

Test Execution:

• Perform HTTP requests to the specified URL.
• Distribute the requests according to the defined concurrency level.
• Ensure that the total number of requests is met.

Report Generation:

At the end of the tests, present a report containing:

• Total time spent on execution.
• Total quantity of requests performed.
• Quantity of requests with HTTP status 200.
• Distribution of other HTTP status codes (such as 404, 500, etc.).

Application Execution:

The application can be executed via docker using the following command:

docker run <your docker image> --url=http://example.com --requests=1000 --concurrency=10

Replace <your docker image> with the name of your Docker image, and adjust the URL, total number of requests, and concurrency level as needed.

Requirements

• Param url is required.
• Params concurrency and requests default values are 10 and 10 respectively.
