Tips and strategies for agile development using Webman

Overview:
Agile development is an iterative and incremental software development method that emphasizes flexibility flexibility and collaboration, with the goal of responding quickly to changes in requirements. Webman is a powerful, easy-to-use Java Web development framework that provides a series of tools and functions to help developers conduct agile development more efficiently. This article will introduce some tips and strategies for agile development using Webman, and provide corresponding code examples.

1. Modular development using Webman
Webman provides the function of modular development, which can divide a large application into multiple independent modules. Each module has independent business logic and corresponding Function. This modular development approach can improve the maintainability and scalability of the code and allows multiple developers to develop at the same time.

The following is a sample code for modular development using Webman:

// 定义一个模块
public class UserModule extends Module {

    // 定义模块的路由
    @Override
    public void routes() {
        route("/user").to(UserController.class, "index");
        route("/user/create").to(UserController.class, "create");
        route("/user/{id}").to(UserController.class, "show");
        // 更多路由定义...
    }

    // 定义模块的控制器
    public static class UserController extends Controller {

        public void index() {
            // 处理首页逻辑...
        }

        public void create() {
            // 处理创建用户逻辑...
        }

        public void show(String id) {
            // 处理展示用户逻辑...
        }

        // 更多控制器方法...
    }
}

// 在应用的入口处加载模块
public class MyApp extends Webman {

    @Override
    public void loadModules() {
        addModule(new UserModule());
        // 加载更多模块...
    }
}

Through modular development, codes with different functions can be separated to facilitate team collaboration and iterative development.

2. Automated testing using Webman
Agile development emphasizes rapid iteration and automated testing. Automated testing is run after each iteration to ensure that new functions will not destroy the original functions. Webman provides rich automated testing functions, making it easy to write and run test scripts.

The following is a sample code for automated testing using Webman:

// 定义一个测试类
public class UserControllerTest extends TestRunner {

    @Override
    public void run() {
        test("Test index action", () -> {
            // 模拟请求
            Request request = mockRequest("/user");
            // 执行控制器方法
            Response response = callAction(UserController.class, "index", request);
            // 断言结果是否符合预期
            assertStatus(200, response);
            assertBodyContains("Welcome to User Index", response);
        });

        test("Test create action", () -> {
            // 模拟请求
            Request request = mockRequest("/user/create", "POST");
            // 设置请求参数
            setParam("username", "john", request);
            setParam("password", "123456", request);
            // 执行控制器方法
            Response response = callAction(UserController.class, "create", request);
            // 断言结果是否符合预期
            assertStatus(200, response);
            assertBodyContains("User created successfully", response);
        });

        // 更多测试...
    }
}

// 运行测试
public class TestRunner {

    public void runAllTests() {
        // 运行所有测试类
        run(UserControllerTest.class);
        // 运行更多测试类...
    }
}

By writing automated test scripts, developers can run tests after each iteration to automatically check the correctness of new functions and stability.
