workspacer-toml-mock

workspacer-toml-mock is a Rust library providing a fully functional mock implementation of the CargoTomlInterface. This mock is useful for simulating various conditions and behaviors of a Cargo.toml file in Rust projects, facilitating robust testing and development environments without direct file manipulation.

Features

• Configurable behavior: Simulate conditions such as missing files, missing required fields, or invalid version formats to test error handling.
• Dependency Management: Configure and simulate dependency version updates.
• Save Operations: Mimic save operations with optional simulated I/O errors.
• Bin Target and Metadata Support: Mock bin targets, author information, license details, and more, allowing comprehensive testing.

Usage

Integrate this crate in scenarios where you require a mock Cargo.toml to test behavior without interacting with the actual files. Utilize the MockCargoToml struct to set desired states and methods to invoke operations like checking file existence or validating integrity.

Example:

let mock = MockCargoToml::fully_valid_config();
assert!(mock.verify_integrity().is_ok());

Implementation

Implements various traits to mimic actual Cargo.toml interactions:

• SaveToDisk
• UpdateDependencyVersionRaw
• GatherBinTargetNames
• And many more

Edition

This crate is developed for the Rust 2024 edition.
