Class Logger

java.lang.Object

com.intellij.openapi.diagnostic.Logger

Direct Known Subclasses:

DefaultLogger

public abstract class Logger
extends Object

A standard interface to write to %system%/log/idea.log (or %system%/testlog/idea.log in tests).

In addition to writing to log file, "error" methods result in showing "IDE fatal errors" dialog in the IDE, in EAP versions or if "idea.fatal.error.notification" system property is "true" (). See com.intellij.diagnostic.DefaultIdeaErrorLogger#canHandle for more details.

Note that in production, a call to "error" doesn't throw exceptions so the execution continues. In tests, however, an AssertionError is thrown.

In most non-performance tests, debug level is enabled by default, so that when a test fails the full contents of its log are printed to stdout.
