Class LogAssert

A test fails if Unity logs a message other than a regular log or warning message. Use LogAssert to check for an expected message in the log so that the test does not fail when Unity logs the message. Use LogAssert.Expect before running the code under test, as the check for expected logs runs at the end of each frame. A test also reports a failure, if an expected message does not appear, or if Unity does not log any regular log or warning messages.

LogAssert lets you expect Unity log messages that would otherwise cause the test to fail.

Properties

Name	Description
ignoreFailingMessages	Set this property to true to prevent unexpected error log messages from triggering an assertion. By default, it is false.

Methods

Name	Description
Expect(LogType, string)	Verifies that a log message of a specified type appears in the log. A test won't fail from an expected error, assertion, or exception log message. It does fail if an expected message does not appear in the log. If multiple LogAssert.Expect are used to expect multiple messages, they are expected to be logged in that order.
Expect(LogType, Regex)	Verifies that a log message of a specified type appears in the log. A test won't fail from an expected error, assertion, or exception log message. It does fail if an expected message does not appear in the log.
NoUnexpectedReceived()	Triggers an assertion when receiving any log messages and fails the test if some are unexpected messages. If multiple tests need to check for no received unexpected logs, consider using the TestMustExpectAllLogsAttribute attribute instead.
