问如何对一个类进行单元测试，它只是一个记录输入和输出到第三方库的适配器？

EN

public interface ILibraryAdapter
{
    string Property1 { get; }
    string Method1(string param1);
    ...
}

public class ThirdPartyLibrary : ILibraryAdapter
{
    private readonly ThirdPartyClass thirdPartyClass;
    private readonly ILog log;

    public ThirdPartyLibrary(ThirdPartyClass thirdPartyClass, ILog log)
    {
        this.thirdPartyClass = thirdPartyClass;
        this.log = log;
    }

    public string Property1
    {
        get
        {
            log.Trace("ThirdPartyClass.get_Property1()");
            var result = thirdPartyClass.Property1;
            log.Trace(string.Format("ThirdPartyClass.get_Property1() returned {0}", result));
            return result;
        }
    }

    public string Method1(string param1)
    {
        log.Trace(string.Format("ThirdPartyClass.Method1({0})", param1));
        var result = thirdPartyClass.Method1(param1);
        log.Trace(string.Format("ThirdPartyClass.Method1({0}) returned {1}", param1, result));
        return result;
    }

    ...
}
