Mix task for running performance load tests on the Double Entry Ledger system.

This task executes a series of load tests to evaluate the system's performance under concurrent transaction processing. It's designed specifically for performance testing and requires the :perf environment to ensure isolation from development or production databases.

Setup

The task automatically:

• Drops any existing database to ensure a clean state
• Creates a new database
• Runs migrations to set up the schema
• Starts the application

Usage

MIX_ENV=perf mix load_test [concurrency]

Options

• concurrency - Optional integer specifying the number of concurrent processes to use in the load test (default: 1)
• seconds - optional float specifying the duration of the load test in seconds (default: 10)

Examples

Run with default concurrency: MIX_ENV=perf mix load_test

Run with specified concurrency: MIX_ENV=perf mix load_test 10

Run with specified concurrency: MIX_ENV=perf mix load_test 10 0.5

Requirements

This task depends on the DoubleEntryLedger.LoadTesting module, which must be defined and implement a run_load_test/1 function that accepts a concurrency level
