Mock Setup() 在设置多个属性时不起作用

如何解决Mock Setup() 在设置多个属性时不起作用

我有这个Moq：

readonly Mock<IHeartbeat> _mockIHeartbeat = new Mock<IHeartbeat>();

[Fact]
public async Task TestWatermarkCheck()
{
    WatermarkOffsets watermarkOffsets = new WatermarkOffsets(1,10);
    Offset offset = new Offset(5);
    _mockIHeartbeat .Setup(x => x.GetWatermarks()).Returns(watermarkOffsets);
    _mockIHeartbeat .Setup(x => x.Getoffset()).Returns(offset);
    HealthCheckContext context = new HealthCheckContext();
    CancellationToken cancellationToken = default;
    Watermark watermark = new Watermark(_mockIHeartbeat.Object);
    HealthCheckResult watermarkHealthCheckResult = await watermark.CheckHealthAsync(context,cancellationToken);
watermarkHealthCheckResult.Status.ToString().Should().Be(HealthCheckResult.Healthy().Status.ToString());
    watermarkHealthCheckResult.Description.ToString().Should().Be("Low: 1 High: 10 Offset: 5");
}

这是 SUT：

public class CheckKafkaWatermark : IHealthCheck
{
    private readonly IHeartbeatCheckHealthHandler _healthHandler;

    public CheckKafkaWatermark(IHeartbeatCheckHealthHandler healthHandler)
    {
        _healthHandler = healthHandler;
    }

    public async Task<HealthCheckResult> CheckHealthAsync(
        HealthCheckContext context,CancellationToken cancellationToken = default)
    {
        return await Task.Fromresult(HealthCheckResult.Healthy($"Low: {_healthHandler.GetWatermarks().Low.ToString()} High: {_healthHandler.GetWatermarks().High.ToString()} Offset: {HealthHandler.Getoffset().Value.ToString()}"));
    }
}

有了这个 _mockIHeartbeat.Setup(x => x.Getoffset().Returns(offset) 似乎没有设置。 IE。它总是显示为 0。

我该如何解决？

解决方法

问题是我的 SUT 中有这一行：

return await Task.FromResult(HealthCheckResult.Healthy($"Low: {_healthHandler.GetWatermarks().Low.ToString()} High: {_healthHandler.GetWatermarks().High.ToString()} Offset: {HealthHandler.GetOffset().Value.ToString()}"));

我应该有：

return await Task.FromResult(HealthCheckResult.Healthy($"Low: {_healthHandler.GetWatermarks().Low.ToString()} High: {_healthHandler.GetWatermarks().High.ToString()} Offset: {_healthHandler.GetOffset().Value.ToString()}"));

顺便说一句，ToString() 在这里是多余的，所以我将行改为

return await Task.FromResult(HealthCheckResult.Healthy($"Low: {_healthHandler.GetWatermarks().Low} High: {_healthHandler.GetWatermarks().High} Offset: {_healthHandler.GetOffset().Value}"));
