Interface ILogRecordFilter

Namespace

LogAssertions

Assembly

LogAssertions.dll

A composable filter over Microsoft.Extensions.Logging.Testing.FakeLogRecord. Built-in filter methods on the assertion fluent chain (AtLevel, Containing, etc.) each create one of these internally; WithFilter(ILogRecordFilter) on the chain accepts arbitrary user implementations, and the LogFilter static factory composes them via All, Any, and Not.

public interface ILogRecordFilter

Remarks

Implementations should be inexpensive to evaluate: they are invoked once per captured record per assertion. The Description is rendered into the expectation line of failure messages and should be terse and human-readable (e.g. "Level = Warning", not a full sentence).

Properties

Description

A short human-readable description used in the expectation summary on failure (for example "Level = Warning" or "Message contains "timeout"").

string Description { get; }

Property Value

string
