public class TestLoggerAssert
extends org.assertj.core.api.AbstractAssert<C,TestLogger>

A set of assertions to validate that logs have been logged to a TestLogger.

Should be thread safe, as this uses testLogger.getLoggingEvents() by default. The assertion mode can be switched to use testLogger.getAllLoggingEvents() by calling anyThread().

Method Detail

anyThread

public TestLoggerAssert anyThread()

Changes the assertion mode to verify that log messages have been logged regardless of which thread actually logged the message.

Returns:

a TestLoggerAssert for chaining

hasLogged

public TestLoggerAssert hasLogged(Level level,
                                  String message,
                                  Object... arguments)

Verify that a log message, at a specific level, has been logged by the test logger.

Parameters:

level - the level of the log message to look for

message - the expected message

arguments - any optional arguments that may be provided to the log message

Returns:

a TestLoggerAssert for chaining

hasLogged

public TestLoggerAssert hasLogged(Throwable throwable,
                                  Level level,
                                  String message,
                                  Object... arguments)

Verify that a log message, at a specific level, has been logged by the test logger in the presence of a Throwable.

Parameters:

throwable - the throwable that is attached to the log message

level - the level of the log message to look for

message - the expected message

arguments - any optional arguments that may be provided to the log message

Returns:

a TestLoggerAssert for chaining

hasLogged

public TestLoggerAssert hasLogged(LoggingEvent event)

Verify that a LoggingEvent has been logged by the test logger.

Parameters:

event - the event to verify presence of

Returns:

a TestLoggerAssert for chaining

hasNotLogged

public TestLoggerAssert hasNotLogged(Level level,
                                     String message,
                                     Object... arguments)

Verify that a log message, at a specific level, has not been logged by the test logger.

Parameters:

level - the level of the log message to look for

message - the expected message

arguments - any optional arguments that may be provided to the log message

Returns:

a TestLoggerAssert for chaining
