c# Moq SetupSequence 2nd call returning null

问题

我正在为一个类编写单元测试，我在其中传递了对同一方法的三个调用，但使用了一些不同的属性。

类中的调用如下：

  1. if (request.ClubLogo != null)
  2. {
  3.     var clubLogoUrl = await _fileStorage.StoreFileAsync(request.ClubLogo, teamInfo.ClubTeam.Club.NationalGoverningBody.Country.Iso.Replace(" ", string.Empty), teamInfo.ClubTeam.Club.ClubName.Replace(" ", string.Empty), FileType.ClubLogo, "clublogo", cancellationToken);
  5.     _logger.LogInformation(clubLogoUrl);
  6.     teamInfo.ClubTeam.Club.SetClubLogoUri(new Uri(clubLogoUrl, UriKind.Absolute));
  7. }
  9. if (request.TeamLogo != null)
  10. {
  11.     var teamLogoUri = await _fileStorage.StoreFileAsync(request.TeamLogo, teamInfo.ClubTeam.Club.NationalGoverningBody.Country.Iso.Replace(" ", string.Empty), teamInfo.ClubTeam.Club.ClubName.Replace(" ", string.Empty), teamInfo.ClubTeam.TeamName.Replace(" ", string.Empty),
  12.         FileType.TeamLogo, request.EventReference.ToLower(), cancellationToken);
  14.     _logger.LogInformation(teamLogoUri);
  15.     teamInfo.ClubTeam.SetTeamLogoUri(new Uri(teamLogoUri, UriKind.Absolute));
  16. }
  18. var teamPhotoUri = await _fileStorage.StoreFileAsync(request.TeamPhoto, teamInfo.ClubTeam.Club.NationalGoverningBody.Country.Iso.Replace(" ", string.Empty), teamInfo.ClubTeam.Club.ClubName.Replace(" ", string.Empty), teamInfo.ClubTeam.TeamName.Replace(" ", string.Empty),
  19.           FileType.TeamPhoto, request.EventReference.ToLower(), cancellationToken);
  21. _logger.LogInformation(teamPhotoUri);
  22. teamInfo.ClubTeam.SetTeamPhotoUri(new Uri(teamPhotoUri, UriKind.Absolute));

然而，当我调用存储团队徽标的方法时，teamLogoUri 为 null，但 clubLogoUri 具有正确的值。

在测试中，我设置如下：

  1. _fileStorage.Setup(x => x.StoreFileAsync(It.IsAny<IFormFile>(), It.IsAny<string>(),
  2.         It.IsAny<string>(), FileType.ClubLogo, It.IsAny<string>(), CancellationToken.None))
  3.         .ReturnsAsync("http://www.someurl.com/1");
  5. _fileStorage.SetupSequence(x => x.StoreFileAsync(It.IsAny<IFormFile>(), It.IsAny<string>(),
  6.     It.IsAny<string>(), It.IsAny<string>(), FileType.ClubLogo, It.IsAny<string>(), CancellationToken.None))
  7.     .ReturnsAsync("http://www.someurl.com/1")
  8.     .ReturnsAsync("http://www.someurl.com/2");

之所以有两个设置是因为根据该接口存在一个重载方法：

  1. public interface IFileStorage
  2. {
  3.     Task<string> StoreFileAsync(IFormFile file, string country, string club, string team, FileType fileType, string containerName, CancellationToken cancellationToken);
  5.     Task<string> StoreFileAsync(IFormFile file, string country, string club, FileType fileType, string containerName, CancellationToken cancellationToken);
  6. }

我无法看出您在这里做错了什么，因为我过去多次设置过序列。

英文:

I am writing a unit test for a class where I am passing three calls to the same method, but with some different properties.

The calls in the class look like this

  1. if (request.ClubLogo != null)
  2. {
  3.     var clubLogoUrl = await _fileStorage.StoreFileAsync(request.ClubLogo, teamInfo.ClubTeam.Club.NationalGoverningBody.Country.Iso.Replace(&quot; &quot;, string.Empty), teamInfo.ClubTeam.Club.ClubName.Replace(&quot; &quot;, string.Empty), FileType.ClubLogo, &quot;clublogo&quot;, cancellationToken);
  5.     _logger.LogInformation(clubLogoUrl);
  6.     teamInfo.ClubTeam.Club.SetClubLogoUri(new Uri(clubLogoUrl, UriKind.Absolute));
  7. }
  9. if (request.TeamLogo != null)
  10. {
  11.     var teamLogoUri = await _fileStorage.StoreFileAsync(request.TeamLogo, teamInfo.ClubTeam.Club.NationalGoverningBody.Country.Iso.Replace(&quot; &quot;, string.Empty), teamInfo.ClubTeam.Club.ClubName.Replace(&quot; &quot;, string.Empty), teamInfo.ClubTeam.TeamName.Replace(&quot; &quot;, string.Empty),
  12.         FileType.TeamLogo, request.EventReference.ToLower(), cancellationToken);
  14.     _logger.LogInformation(teamLogoUri);
  15.     teamInfo.ClubTeam.SetTeamLogoUri(new Uri(teamLogoUri, UriKind.Absolute));
  16. }
  18. var teamPhotoUri = await _fileStorage.StoreFileAsync(request.TeamPhoto, teamInfo.ClubTeam.Club.NationalGoverningBody.Country.Iso.Replace(&quot; &quot;, string.Empty), teamInfo.ClubTeam.Club.ClubName.Replace(&quot; &quot;, string.Empty), teamInfo.ClubTeam.TeamName.Replace(&quot; &quot;, string.Empty),
  19.           FileType.TeamPhoto, request.EventReference.ToLower(), cancellationToken);
  21. _logger.LogInformation(teamPhotoUri);
  22. teamInfo.ClubTeam.SetTeamPhotoUri(new Uri(teamPhotoUri, UriKind.Absolute));

However, when I make the call to store the team logo, teamLogoUri is null, but clubLogoUri has the correct value.

In the test I am setting this up like this

  1. _fileStorage.Setup(x =&gt; x.StoreFileAsync(It.IsAny&lt;IFormFile&gt;(), It.IsAny&lt;string&gt;(),
  2. 		It.IsAny&lt;string&gt;(), FileType.ClubLogo, It.IsAny&lt;string&gt;(), CancellationToken.None))
  3. 	.ReturnsAsync(&quot;http://www.someurl.com/1&quot;);
  5. _fileStorage.SetupSequence(x =&gt; x.StoreFileAsync(It.IsAny&lt;IFormFile&gt;(), It.IsAny&lt;string&gt;(),
  6. 	It.IsAny&lt;string&gt;(), It.IsAny&lt;string&gt;(), FileType.ClubLogo, It.IsAny&lt;string&gt;(), CancellationToken.None))
  7. 	.ReturnsAsync(&quot;http://www.someurl.com/1&quot;)
  8. 	.ReturnsAsync(&quot;http://www.someurl.com/2&quot;);

The reason there is two setups is because there is an overloaded method as per this interface

  1. public interface IFileStorage
  2. {
  3.     Task&lt;string&gt; StoreFileAsync(IFormFile file, string country, string club, string team, FileType fileType, string containerName, CancellationToken cancellationToken);
  5.     Task&lt;string&gt; StoreFileAsync(IFormFile file, string country, string club, FileType fileType, string containerName, CancellationToken cancellationToken);
  6. }

I cant see what I have done wrong here as I have setup a sequence many times in the past.

答案1

得分: 1

根据我看到的内容，您正在使用FileType.ClubLogo来设置序列，而以下调用是FileType.TeamLogo和FileType.TeamPhoto，请将其更改为It.IsAny&lt;FileType&gt;()，或者设置单独的调用。

英文:

As far as I can see you are setting up sequence with FileType.ClubLogo while the following calls are FileType.TeamLogo and FileType.TeamPhoto, change it to It.IsAny&lt;FileType&gt;(), or setup separate calls.

答案2

得分: 1

你正在将 FileType 参数与 FileType.ClubLogo 进行匹配，而在第二次调用中，你传递了 FileType.TeamLogo。请使用 It.Is<T> 并使用表达式匹配两者：

  1. _fileStorage.SetupSequence(x =>
  2.     x.StoreFileAsync(
  3.         It.IsAny<IFormFile>(),
  4.         It.IsAny<string>(),
  5.         It.IsAny<string>(),
  6.         It.IsAny<string>(),
  7.         It.Is<FileType>(f => f == FileType.ClubLogo || f == FileType.TeamLogo),
  8.         It.IsAny<string>(),
  9.         CancellationToken.None))
  10.     .ReturnsAsync("http://www.someurl.com/1")
  11.     .ReturnsAsync("http://www.someurl.com/2");
英文:

You are matching the FileType argument against FileType.ClubLogo and in the second call you are passing FileType.TeamLogo. Use It.Is&lt;T&gt; with an expression to match both:

  1. _fileStorage.SetupSequence(x =&gt;
  2.     x.StoreFileAsync(
  3.         It.IsAny&lt;IFormFile&gt;(),
  4.         It.IsAny&lt;string&gt;(),
  5.         It.IsAny&lt;string&gt;(),
  6.         It.IsAny&lt;string&gt;(),
  7.         It.Is&lt;FileType&gt;(f =&gt; f == FileType.ClubLogo || f == FileType.TeamLogo),
  8.         It.IsAny&lt;string&gt;(),
  9.         CancellationToken.None))
  10.     .ReturnsAsync(&quot;http://www.someurl.com/1&quot;)
  11.     .ReturnsAsync(&quot;http://www.someurl.com/2&quot;);
