整套单元测试用例都通过了，但是如果我 运行 个人测试失败

Question

下面是我的一组单元测试用例。不知道是不是我写错了。但是如果我 运行 一次全部通过（进入测试资源管理器--> 右键单击​​ CosmosDataTests--> 运行），我的所有单元测试用例都会通过。但是如果我尝试 运行 测试资源管理器中的单个测试用例，它会失败......说“所有者资源不可用”。我在这里做错了什么？？

这是我的代码：

public class CosmosDataFixture : IDisposable
    {
        public static readonly string CosmosEndpoint = "https://localhost:8081";
        public static readonly string EmulatorKey = "C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==";
        public static readonly string DatabaseId = "dummydatabase";
        public static readonly string RecordingCollection = "testcontainer";
        public static string Root = Directory.GetParent( Directory.GetCurrentDirectory() ).Parent.Parent.FullName;
        public static DocumentClient client { get; set; }

        public async Task ReadAllData( DocumentClient client )
        {
            string path = Path.Combine( Root, @"TestData\Dummydata.json" );
            var lines = File.ReadAllLines( path );
            var jData = new List<JObject>();
            foreach( var line in lines )
            {
                var data = JsonConvert.DeserializeObject<JObject>( line );
                jData.Add( data );
            }
            Uri collectionUri = UriFactory.CreateDocumentCollectionUri( DatabaseId, RecordingCollection );
            foreach( var obj in jData )
            {
               await client.UpsertDocumentAsync( collectionUri, obj );
            }
        }

        public async Task ReadConfigAsync()
        {

          
            client = new DocumentClient( new Uri( CosmosEndpoint ), EmulatorKey,
                 new ConnectionPolicy
                 {
                     ConnectionMode = ConnectionMode.Direct,
                     ConnectionProtocol = Protocol.Tcp

                 } );
            await client.CreateDatabaseIfNotExistsAsync( new Database { Id = DatabaseId } );
            await client.CreateDocumentCollectionIfNotExistsAsync( UriFactory.CreateDatabaseUri( DatabaseId ),
                new DocumentCollection { Id = RecordingCollection } );
            await ReadAllData( client );
        }    

        

        private async Task DeleteDatabaseFromPowerShell()
        {
           await client.DeleteDatabaseAsync( UriFactory.CreateDatabaseUri( DatabaseId ) );
        }
        public CosmosDataFixture()
        {
                      
            ReadConfigAsync();     
        }


        public void Dispose()
        {
          DeleteDatabaseFromPowerShell();
        }
    }   
    public class CosmosDataTests : IClassFixture<CosmosDataFixture>
    {            

        [Fact]
        public async Task CheckDatabaseandCollectionCreation()
        {          
            List<string> collectionName = new List<string>();
            var uri = UriFactory.CreateDatabaseUri( CosmosDataFixture.DatabaseId);
            var collections = await CosmosDataFixture.client.ReadDocumentCollectionFeedAsync( uri );
            foreach( var collection in collections )
            {
                collectionName.Add( collection.Id);
            }
            Assert.Contains( "testcontainer", collectionName );     
        }

        [Fact]
        public void AddDataInCosmosDbEmulator()
        { ...2nd test case..and so on}

Answer 1

终于弄明白了，这是一个异步等待问题。在我的构造函数中调用并在 dispose 中调用的方法没有等待，这就是我出错的原因。通过添加 .GetAwaiter().Getresult()

修复它

public CosmosDataFixture()
        {
                      
            ReadConfigAsync().GetAwaiter.GetResult();     
        }


        public void Dispose()
        {
          DeleteDatabaseFromPowerShell().GetAwaiter.GetResult();
        }
