Module mock_executor 

Mock Command Executor for Testing Quality Gates

This module provides infrastructure for mocking external command execution to enable unit testing of quality gate logic without running actual commands.

Design

Uses trait-based dependency injection to allow:

• Real execution in production (RealCommandExecutor)
• Mock execution in tests (MockCommandExecutor)

Example

let mut mock = MockCommandExecutor::new();
mock.register("cargo", &["clippy"], CommandResult::success("Clippy passed"));
let result = mock.execute("cargo", &["clippy"]);
assert!(result.success);

Structs

CommandKey

Key for identifying a command (program + args combination)

CommandResult

Result of command execution

MockCommandExecutor

Mock command executor for testing

RealCommandExecutor

Real command executor using std::process::Command

Traits

CommandExecutor

Trait for executing external commands
