KeywordEngine 1.1.0

KeywordEngine

The KeywordEngine is a keyword-driven framework execution engine for automating test cases. It can easily integrate with any C# unit testing frameworks like NUnit, XUnit, and MSTest.

At a Glance:

• Compatible with .NET Core 6+.
• Supports any C# unit testing frameworks like NUnit, XUnit, and MSTest.
• No external dependencies beyond standard base libraries.
• Maps parameters to scalar types, including Enums, Guid, DateTimeOffset, and nullable scalar types.
• Supports additional keyword data/parameters using the ITestContext interface.
• Automatically ignores unused and additional provided parameters.
• Supports custom DependencyInjection to resolve keyword dependencies via the IDependencyResolver interface.
• Uses InvariantCulture for default parameter parsing.

Quick Start Example:

using System;
using KeywordEngine.Core;
using KeywordEngine.Test.Keywords;
using KeywordEngine.Abstraction;
using KeywordEngine.Models;

// Define keywords
internal class MyFirstActionKeyword : IActionKeyword
{
    private readonly string _message;
    public MyFirstActionKeyword(string message)
    {
        _message = message;
    }

    public Task<KeywordResponse> Execute()
    {
        Console.WriteLine(_message);
        Console.WriteLine($"{nameof(MyFirstActionKeyword)} keyword executed.");

        return Task.FromResult(new KeywordResponse
        {
            Status = ResponseStatus.Executed,
            Message = $"{nameof(MyFirstActionKeyword)} keyword executed."
        });
    }
}

internal class MyFirstVerifyKeyword : IVerifyKeyword
{
    public Task<KeywordResponse> Execute()
    {
        Console.WriteLine($"{nameof(MyFirstVerifyKeyword)} keyword executed.");

        return Task.FromResult(new KeywordResponse
        {
            Status = ResponseStatus.Executed,
            Message = $"{nameof(MyFirstVerifyKeyword)} keyword executed."
        });
    }
}

// Create test steps
var test = new TestCase
{
    Id = 1,
    Title = "Demo test",
    Steps = new List<TestStep>
    {
        new TestStep
        {
            Title = "First Step",
            Keyword = nameof(MyFirstActionKeyword),
            Index = 0,
            Parameters = new List<Parameter>
            {
                new Parameter
                {
                    Name = "message",
                    Value = "Hello"
                }
            }
        },
        new TestStep
        {
            Title = "Second Step",
            Keyword = nameof(MyFirstVerifyKeyword),
            Index = 1,
            Parameters = new List<Parameter>()
        }
    }
};

// Initialize dependency injection and import keywords
var testRunner = TestRunnerFactory.CreateTestRunner();

// Execute test
await testRunner.ExecuteAsync(test);

Enhanced Keyword and Test Runner Workflow

Centralized Dependency Injection

The framework now supports centralized dependency injection using DependencyResolverFactory. You don't need to create dependency injection manually for every test case. Keywords and dependencies are automatically resolved.

Simplified Test Runner Creation

The TestRunnerFactory simplifies test runner creation. It handles:

• Keyword Importing: Automatically imports keywords if not already done.
• Dependency Injection: Uses a singleton IDependencyResolver instance.
• Result Publishing: Provides a default ConsoleResultPublisher or allows custom publishers.

Updated TestRunnerFactory Example

public static class TestRunnerFactory
{
    private static TestCaseRunner? _testCaseRunner;

    public static TestCaseRunner CreateTestRunner()
    {
        if (_testCaseRunner == null)
        {
            var dependencyResolver = DependencyResolverFactory.CreateResolver();

            if (Module.NoKeywords)
            {
                Module.Import(typeof(MyFirstActionKeyword).Assembly);
            }

            _testCaseRunner = new TestCaseRunner(
                dependencyResolver: dependencyResolver,
                testResultPublisher: new ConsoleResultPublisher());
        }

        return _testCaseRunner;
    }
}

Custom Result Publisher

You can define a custom result publisher by implementing the ITestResultPublisher interface. For example:

public class CustomResultPublisher : ITestResultPublisher
{
    public Task PublishTestResultAsync(TestResult testResult)
    {
        // Custom publishing logic, e.g., save to a database or log
        Console.WriteLine($"Publishing test result: {testResult.TestTitle}");
        return Task.CompletedTask;
    }
}

Using a Custom Result Publisher

var testRunner = new TestCaseRunner(
    testResultPublisher: new CustomResultPublisher()
);

Benefits of the New Flow

1. Ease of Use:

   • No manual keyword imports or dependency injection setup.
   • Centralized and reusable DI logic.

2. Modular and Extensible:

   • Easily extendable with custom publishers or additional keyword assemblies.

3. Robust Execution:

   • Centralized exception handling and result publishing ensure consistent test execution.
