C# 如何模拟 Configuration.GetSection ("foo:bar").Get<List<string>>()

Question

我在 config.json 文件中有如下列表 `

{
  "foo": {
    "bar": [
      "1",
      "2",
      "3"
    ]
  }
}`

我可以在运行时使用

获取列表

Configuration.GetSection("foo:bar").Get<List<string>>()

我想模拟 configuration.GetSection 来编写单元测试。

以下语法失败

mockConfigRepo
    .SetupGet(x => x.GetSection("reportLanguageSettings:reportLanguageList").Get<List<string>>())
    .Returns(reportLanguages);

我能够使用 ConfigurationBuilder 解决它。希望这会有所帮助

  var appSettings = @"{""AppSettings"":{
            ""Key1"" : ""Value1"",
            ""Key2"" : ""Value2"",
            ""Key3"" : ""Value3""
            }}";

  var builder = new ConfigurationBuilder();

  builder.AddJsonStream(new MemoryStream(Encoding.UTF8.GetBytes(appSettings)));

  var configuration= builder.Build();
