## What it is
ParaTest is a CLI tool that runs PHPUnit test suites in parallel across multiple processes. It requires zero configuration and can combine code coverage reports from all parallel workers into a single report.

## Use cases
- speed up slow phpunit test suites by running tests in parallel
- run phpunit tests across multiple cpu cores
- combine code coverage reports from parallel test processes
- parallelize tests by testcase or by individual test method
- give each parallel test process its own database via TEST_TOKEN

## When to choose
- you have a large PHPUnit suite that takes too long to run sequentially
- you want parallel testing with no extra bootstrap or configuration
- you need merged code coverage from parallel test runs

## When to avoid
- your project uses an older PHPUnit version, since only the latest is supported
- your tests are not isolated and share state like databases or files
- you use a testing framework other than PHPUnit
