如何使用Moq模拟此代码进行单元测试？

public interface IDataService
{
    string GetData();
}

public class BusinessLogic
{
    private readonly IDataService _dataService;

    public BusinessLogic(IDataService dataService)
    {
        _dataService = dataService;
    }

    public string ProcessData()
    {
        var data = _dataService.GetData();
        // 进行一些数据处理逻辑
        return data.ToUpper();
    }
}

[Test]
public void ProcessData_Should_Return_UpperCaseData()
{
    // 创建模拟对象
    var mockDataService = new Mock<IDataService>();

    // 设置模拟对象的行为
    mockDataService.Setup(d => d.GetData()).Returns("test data");

    // 创建被测试的业务逻辑对象，并将模拟对象传入构造函数
    var businessLogic = new BusinessLogic(mockDataService.Object);

    // 调用被测试的方法
    var result = businessLogic.ProcessData();

    // 断言结果是否符合预期
    Assert.AreEqual("TEST DATA", result);
}
