I need xUnit test case of this. Microsoft.Azure.Cosmos Container

Question

I have use Cosmosdb Container its abstract class. I need xUnit test case with mock using Moq library

public class SmsTemplateRepository : ISmsTemplateRepository
{
    private Container _container;

    public SmsTemplateRepository(CosmosClient dbClient, string databaseName, string containerName) 
    {
        _container = dbClient.GetContainer(databaseName, containerName);
    }

    public IEnumerable<SmsTemplate> GetAll()
    {
        return _container.GetItemLinqQueryable<SmsTemplate>(true);
    }

    **public async Task InsertAsync(SmsTemplate smsTemplate)
    {
        await _container.CreateItemAsync(smsTemplate);
    }**
}

Could you share what attempt have you done to mock the object and which is the failure or error you are getting? — Matias Quaranta, Nov 27 '19 at 16:11
No error i am not able to mock this method. public IEnumerable GetAll() { return _container.GetItemLinqQueryable(true); } — , Nov 28 '19 at 04:37
@DavinderSingh hi Davinder, were you able to solve this, do you have a working sample ? or can you mark an answer which worked for you ? — sumit sharma, Jun 12 '20 at 07:15

You have to mock the whole chain from the dependency you pass into the constructor of the repository.

Create a list of templates you want to simulate GetAll to return:

var smsTemplates = new[]
{
  new SmsTemplate { Name = "Name1" },
  new SmsTemplate { Name = "Name3" }
}.AsQueryable()
 .OrderBy(x => x.Name);

Create a mocked CosmosClient and a mocked Container and setup the CosmosClient mock to return the mocked container:

var container = new Mock<Container>();
var client = new Mock<CosmosClient>();

client.Setup(x => x.GetContainer(It.IsAny<string>(), It.IsAny<string>())
      .Returns(container.Object);

Setup the mocked container to return the template list and pass in the mocked CosmosClient to the constructor of the repository:

container.Setup(x => x.GetItemLinqQueryable<SmsTemplate>(It.IsAny<bool>())
         .Returns(smsTemplates);
var repository = new SmsTemplateRepository(client.Object, ....);

GetAll will now return the smsTemplates

it gives me error (Can not convert List to FeedResponse) while putting List in Returns, do you know an alternative ? — sumit sharma, Jun 12 '20 at 08:02
