Test a Plugin

Minco 0.6.0 publishes one minco-test builder for official and third-party-style plugins. It checks package metadata, distribution intent, descriptor overlap, and—when supplied—deterministic plugin composition.

1. Create the Package Boundary

The current CLI can scaffold an official-style package:

bash

cargo minco plugin new example

For an external package, keep the distribution record inside the crate archive and point to it from Cargo metadata.

toml

[package]
name = "minco-plugin-example"
version = "0.1.0"
include = ["src/**", "Cargo.toml", "minco-plugin.json"]

[package.metadata.minco]
plugin = "minco-plugin.json"

Use exact 0.6.0 registry dependencies for published packages. Use reviewed path dependencies only while developing coordinated changes from a Minco source checkout.

2. Declare Distribution Intent

Start with the smallest strict schema. Add capabilities, configuration, operations, database assets, resources, health, data classes, wake sources, and cost intent only when the plugin really supports them.

json

{
  "schema": 1,
  "id": "example",
  "kind": "plugin",
  "plugin_version": "0.1.0",
  "core_compatibility": "^0.6.0",
  "stability": "experimental",
  "default_enabled": false,
  "feature": "plugin-example",
  "runtimes": ["native"],
  "retention": "none",
  "failure_policy": {
    "mode": "fail_closed",
    "description": "Example failures remain explicit."
  },
  "documentation": {
    "reference": "https://docs.rs/minco-plugin-example"
  },
  "conformance": {
    "profile": "minco-plugin-v1",
    "evidence": ["cargo test --all-features --locked"]
  }
}

Evidence strings are labels. Validation never executes them.

3. Exercise the Public Builder

Test from the plugin package root so Cargo inclusion and relative assets match the archive boundary.

rust

use minco_test::{ConformanceStatus, PluginConformance};

let report = PluginConformance::for_package(env!("CARGO_MANIFEST_DIR"))
    .with_plugin(ExamplePlugin)
    .run();

report.assert_passed();
assert_eq!(
    report.assurance.plugin_lifecycle,
    ConformanceStatus::Passed
);
assert_eq!(
    report.assurance.provider_live,
    ConformanceStatus::NotRun
);

Use .with_configuration(value) when the plugin requires settings. Use .with_supporting_plugin(plugin) for declared graph dependencies. A descriptor-only run can assess package/descriptor overlap but must report the lifecycle as not_assessed.

4. Run Both Package and Catalog Checks

bash

cargo test --all-features --locked
cargo minco plugin validate --json
cargo minco plugin test --all --json

plugin test --all covers local catalog packages only. It does not download a registry package or execute an evidence command.

5. Interpret the Boundary Correctly

Passing proves an offline plugin contract and, when a concrete plugin is supplied, deterministic composition. It does not prove application readiness, database migration behavior, a provider call, an AWS deployment, or production fitness.

See the Plugin Conformance reference and the standalone exercised example.
