Test Builders for Commands

Commands should provide test builders for simplified unit testing.

Example

use torrust_tracker_deployer::application::commands::destroy::tests::DestroyCommandTestBuilder;

#[test]
fn it_should_create_destroy_command_with_all_dependencies() {
    let (command, _temp_dir) = DestroyCommandTestBuilder::new().build();

    // Verify the command was created
    assert_eq!(Arc::strong_count(&command.opentofu_client), 1);
}

Benefits of Test Builders

• Manages TempDir lifecycle automatically
• Provides sensible defaults for all dependencies
• Allows selective customization of dependencies
• Returns only the command and necessary test artifacts
