我正在编写单元测试。为了测试以下方法,
public async Task<Guid> CreateWebJobStatus(string blobId, Guid loggedInUserId, string loggedInUserEmail) {
Guid webJobStatusId = Guid.NewGuid();
WebJobStatus newWebJobStatus = new WebJobStatus
{
WorkJobStatusId = webJobStatusId,
TransactionId = Guid.NewGuid(),
Status = (int)WebJobStatusEnum.PENDING,
BlobId = blobId,
UserId = loggedInUserId,
UserEmail = loggedInUserEmail,
};
await _dbContext.WebJobStatus.AddAsync(newWebJobStatus);
await _dbContext.SaveChangesAsync();
return webJobStatusId;
}
我嘲笑dbset和dbcontext
public async void CreateWebJobStatusTest() {
var dbOption = new DbContextOptions<TimeSeriesDbContext>();
var mockDbContext = new Mock<TimeSeriesDbContext>(dbOption);
var mockConfig = new Mock<IConfiguration>();
var instance = new WebJobStatusRepository(mockConfig.Object, mockDbContext.Object);
var mockValidWebJobId = "11111111-1111-1111-1111-111111111111";
var webjobStatusList = new List<WebJobStatus>() {
new WebJobStatus {
WorkJobStatusId = Guid.Parse(mockValidWebJobId),
GroupName = "testGroupName",
Status = 3,
CreatedDate = DateTimeOffset.UtcNow.AddDays(-10)
}
};
var mockWebJobDbSet = UnitTestUtil.CreateDbSetMock<WebJobStatus>(webjobStatusList.AsQueryable());
mockDbContext.Setup(x => x.WebJobStatus).Returns(mockWebJobDbSet.Object);
mockWebJobDbSet.Setup(x => x.AddAsync(It.IsAny<WebJobStatus>(), It.IsAny<System.Threading.CancellationToken>())).Callback((WebJobStatus wj) =>{webjobstatusList.add(wj);});
var mockuserId = Guid.Parse("22222222-1111-1111-1111-111111111111");
var result = await instance.CreateWebJobStatus("testBlobId.tsv", mockuserId, "testEmail");
Assert.IsType<Guid>(result);
mockDbContext.Verify(x => x.SaveChangesAsync(It.IsAny<System.Threading.CancellationToken>()), Times.Once);
mockWebJobDbSet.Verify(x => x.AddAsync(It.IsAny<WebJobStatus>(), It.IsAny<System.Threading.CancellationToken>()), Times.Once);
}
除了
AddAsync
之外,其他所有东西都按预期工作,例外是无效的回调。具有参数(WebJobStatus,CancellationToken)的方法上的设置无法调用具有参数(WebJobStatus)的回调。
有人知道吗?
最佳答案
您将需要返回任务以允许异步/等待调用
await _dbContext.WebJobStatus.AddAsync(newWebJobStatus);
流到完成。
因此,假设Add返回添加的对象
mockWebJobDbSet
.Setup(_ => _.AddAsync(It.IsAny<WebJobStatus>(), It.IsAny<System.Threading.CancellationToken>()))
.Callback((WebJobStatus model, CancellationToken token) => { webjobstatusList.Add(model); })
.Returns((WebJobStatus model, CancellationToken token) => Task.FromResult((EntityEntry<WebJobStatus>)null));
请注意,方法
Setup
需要两个参数,因此Callback
和Returns
如果要使用捕获的参数,也将需要两个参数。
