c# nUnit，日志模拟验证在代码中多次调用的地方不起作用

发布于 2025-01-15 20:46:02 字数 699 浏览 1 评论 0 原文

我正在从事 .NET CORE 3.1 nUnit 测试并尝试验证日志。我注意到，单次调用的日志确实可以识别并工作，并且如果相同的登录循环（例如记录不存在时的 log.logDebug）不适用于验证代码。

log 是 ILogger 模拟

类

log.LogDebug("No files discovered in testing....");

Test的实例

_loggerMoq.Verify(
            x => x.Log(
                LogLevel.Debug,
                It.IsAny<EventId>(),
                It.Is<It.IsAnyType>((o, t) => string.Equals("No files discovered in testing....", o.ToString(), StringComparison.InvariantCultureIgnoreCase)),
                It.IsAny<Exception>(),
                It.IsAny<Func<It.IsAnyType, Exception, string>>()),
            Times.Once);

I am working on .NET CORE 3.1 nUnit tests and trying to verify log. I have notice that log that call single time does recognize and work and if same log in loop for example log.logDebug when record does not exist does not work with verify code.

log is instance of ILogger mock

class

log.LogDebug("No files discovered in testing....");

Test

_loggerMoq.Verify(
            x => x.Log(
                LogLevel.Debug,
                It.IsAny<EventId>(),
                It.Is<It.IsAnyType>((o, t) => string.Equals("No files discovered in testing....", o.ToString(), StringComparison.InvariantCultureIgnoreCase)),
                It.IsAny<Exception>(),
                It.IsAny<Func<It.IsAnyType, Exception, string>>()),
            Times.Once);

您必须将 It.IsAny>()), 更改为 (Func)It.IsAny< ;object>()),

不确定为什么会这样，这是 Moq 库中的一个已知错误。
