.NET 中如何用 Moq 对 IRedisClientFactory 进行 mock

在一个 .NET 10 项目的测试代码中，想对下面的 IRedisClientFactory 进行 mock，请问如何实现？

public class UCenterService(
    IRedisClientFactory redisClientFactory,
    IOptions<UCenterClientOptions> options) : IUCenterService
{
    private readonly IRedisDatabase _redisCache = redisClientFactory
            .GetRedisClient(options.Value.RedisCache)
            .GetDefaultDatabase();
}

回答

通过下面的 mock 代码实现了

var redisDatabaseMock = new Mock<IRedisDatabase>();

var redisClientMock = new Mock<IRedisClient>();
redisClientMock
    .Setup(x => x.GetDefaultDatabase())
    .Returns(redisDatabaseMock.Object);

var redisClientFactoryMock = new Mock<IRedisClientFactory>();
redisClientFactoryMock
    .Setup(x => x.GetRedisClient(It.IsAny<string>()))
    .Returns(redisClientMock.Object);

var db = redisClientFactoryMock.Object
    .GetRedisClient("default")
    .GetDefaultDatabase();
