Overview
The process package provides a pluggable and mockable abstraction for invoking external processes in Dart, enabling consistent execution of system commands across platforms. Designed with testing in mind, it allows developers to easily substitute real process execution with mocks during unit tests, improving test reliability and isolation. It supports all major platforms including Android, iOS, macOS, Windows, and Linux, making it ideal for cross-platform applications that require system interaction. The package simplifies integration with command-line tools and shell scripts while maintaining clean, testable code.
Use cases
- Unit testing system command invocations
- Cross-platform script execution
- Mocking external process calls in tests
- Integrating with CLI tools
- Automating build or deployment tasks
Key features
- Pluggable process execution
- Built-in mocking support
- Cross-platform compatibility
- Clean API for command execution
- Integration with Dart's testing framework
Suitable for
- Test-driven development
- CI/CD pipelines
- Command-line tool integrations
- Dart applications requiring system calls
- Developers needing predictable process behavior
Considerations
- Requires setup for custom process implementations
- Mocking must be explicitly configured in tests
- Not intended for high-performance or frequent process spawning
- Limited to synchronous and basic asynchronous process handling
- Depends on correct platform-specific command paths
