io.aviso.logging.capture — io.aviso/logging 0.3.2

Capture logged events for in-process debugging and testing.

clear-logged-events clj

(clear-logged-events)

Clears any captured log events.

logged-events clj

(logged-events)

Returns a snapshot, as a vector, of all events logged since the last clear of the log (the start of the current test).

Event maps have the following keys:

:level : :trace, :debug, etc.

:logger : The name of the logger, as a keyword

:data : A map of the data parsed as EDN from the event message. If the EDN data can't be parsed, then this will be a map of :message and the message string.

:timestamp : System time (milliseconds since epoch) of the event.

:thread-name : Name of thread on which the event was logged.

:ex : The exception associated with the event. This is a map with keys :message and :class-name, and optionally :cause.

Returns a lazy seq of events. However, note that the seq is based on a mutable list that will be unstable if further logging takes place.

logged-events-fixture clj

(logged-events-fixture f)

Using the expected logback configuration, installs an appender that captures logged EDN data into the *log-data atom.

The appender is removed at the end of the test BUT the captured log data is kept until the start of the next test.

NOTE: When using io.aviso.logging/install-pretty-logging, the :ex data will always be nil (install-pretty-logging overrides the message with a pretty-formatted exception, which results in the exception data seen by the appender being nil.
