Symfony2禁用测试环境中的日志

How to disable any logs in test environment? Question related to correct monolog setup in config_test.yml file, that inherited from config_dev.yml, where config looks like this:

monolog:
    handlers:
        main:
            type:         fingers_crossed
            action_level: error
            handler:      grouped_main
        streamed_main:
            type:   stream
            path:   "%kernel.logs_dir%/%kernel.environment%.log"
            level:  debug
        grouped_main:
            type:    group
            members: [streamed_main]
        console:
            type:   console
            bubble: false
            verbosity_levels:
                VERBOSITY_VERBOSE: INFO
                VERBOSITY_VERY_VERBOSE: DEBUG
            channels: ["!doctrine"]
        console_very_verbose:
            type:   console
            bubble: false
            verbosity_levels:
                VERBOSITY_VERBOSE: NOTICE
                VERBOSITY_VERY_VERBOSE: NOTICE
                VERBOSITY_DEBUG: DEBUG
            channels: ["doctrine"]

You can use the inheritance to change the type of the handler, and even the level:

config_test.yml

monolog:
    handlers:
        main:
            type:         fingers_crossed
            action_level: error
            handler:      grouped_main
        streamed_main:
            type:   fingers_crossed
            path:   "%kernel.logs_dir%/%kernel.environment%.log"
            level:  error

You can also change to bubble: false

Maybe you can also reconsider no using logs, you can save it on syslog and other backends which can be more convenient to you!
