无法调用此函数 CallComplianceStarter ...

得到错误 cs1929 Isetup'不包含'ReturnsAsync'和最佳扩展方法重载的定义

Answer 1

选项 A

您应该将CallComplianceStarter 签名更改为同步。

虽然 _mockService 确实有一个方法：

Task<WorkFlowsResponse> CallComplianceStarter(string flowName, MessageHeader messageHeader)

测试应该是

public WorkFlowsResponse CallComplianceStarter(string flowName, MessageHeader messageHeader)
{                
    // Imeplementation         
    return new WorkFlowsResponse { TriggerFlow = flowName };               
}

如果您注意ReturnsAsync 签名，您会发现它有一个只接受参数的重载：TResult value。

public static IReturnsResult<TMock> ReturnsAsync<TMock, TResult>(this IReturns<TMock, Task<TResult>> mock, TResult value) where TMock : class;

选项 B

不知道为什么在测试中首先需要这个CallComplianceStarter？你只是从生产中复制它吗？我相信您只需要一个特定的返回值，例如 new WorkFlowsResponse { TriggerFlow = "MyFlowName" };。

并将其用于：

var expected = new WorkFlowsResponse { TriggerFlow = "MyFlowName" };
_mockService.Setup(x => x.CallComplianceStarter(It.IsAny<string>(), It.IsAny<MessageHeader>()))
.ReturnsAsync(expected);
