.file_log(level, lines) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Writes an array of lines to the common Kitchen logger’s file device at the given severity level. If the Kitchen logger is set to debug severity, then the array of lines will also be written to the console output.

Parameters:

    the desired log level

  • lines (Array<String>) —

    an array of strings to log

end

.with_friendly_errors ⇒ Object

Yields to a code block in order to consistently emit a useful crash/error message and exit appropriately. There are two primary failure conditions: an expected instance failure, and any other unexpected failures.

Note This method may call ‘Kernel.exit` so may not return if the yielded code block raises an exception.

## Instance Failure

This is an expected failure scenario which could happen if an instance couldn’t be created, a Chef run didn’t successfully converge, a post-convergence test suite failed, etc. In other words, you can count on encountering these failures all the time–this is Kitchen’s worldview: crash early and often. In this case a cleanly formatted exception is written to ‘STDERR` and the exception message is written to the common Kitchen file logger.

## Unexpected Failure

All other forms of ‘Kitchen::Error` exceptions are considered unexpected or unplanned exceptions, typically from user configuration errors, driver or provisioner coding issues or bugs, or internal code issues. Given a stable release of Kitchen and a solid set of drivers and provisioners, the most likely cause of this is user configuration error originating in the `.kitchen.yml` setup. For this reason, the exception is written to `STDERR`, a full formatted exception trace is written to the common Kitchen file logger, and a message is displayed on `STDERR` to the user informing them to check the log files and check their configuration with the `kitchen diagnose` subcommand.

Raises:

  • (SystemExit) —

    if an exception is raised in the yielded block
