Module testing 

Testing utilities for plugin development.

This module provides two complementary approaches for testing plugins:

• PluginTestRunner - A test runner with assertion methods and fixture-based testing
• TestCase - A builder for inline, declarative test assertions

Quick Example

use nginx_lint_plugin::prelude::*;
use nginx_lint_plugin::testing::{PluginTestRunner, TestCase};

// Define a simple plugin for demonstration

// Use PluginTestRunner for quick assertions
let runner = PluginTestRunner::new(MyPlugin);
runner.assert_has_errors("http {\n    bad_directive on;\n}");
runner.assert_no_errors("http {\n    good_directive on;\n}");

// Use TestCase for declarative, detailed assertions
TestCase::new("http {\n    bad_directive on;\n}")
    .expect_error_count(1)
    .expect_error_on_line(2)
    .run(&MyPlugin);

Fixture Directory Structure

    └── expected/nginx.conf   # Config after applying fixes (no errors expected)

Structs

PluginTestRunner
