hi,

do you know how and where to configure logging for logging for Geb 4.0 and Selenium 4.0.0-beta-2?

I set the following in GebConfig

LoggingPreferences logPrefs = new LoggingPreferences()
logPrefs.enable(LogType.BROWSER, Level.FINE)
logPrefs.enable(LogType.PERFORMANCE, Level.INFO)
caps.setCapability(CapabilityType.LOGGING_PREFS, logPrefs)

and I get only traffic logs, everything is logged there, so many traffic logs nothing else can be seen.

how do I set logging to get chrome console logs and "usual" logs (which show how the script behaves)?

thank you!

Hi,

This is more of a Selenium question than a Geb question, to be honest, you might be provided with better support in a Selenium specific channel. This also might be driver/browser specific.

FWIW, this is what we successfully use in our GebConfig.groovy file on my project for capturing javascript console logging with Chrome and Selenium 3.14.0:

def capabilities = DesiredCapabilities.chrome()
def logPrefs = new LoggingPreferences()
logPrefs.enable(BROWSER, Level.INFO)
capabilities.setCapability(LOGGING_PREFS, logPrefs)

def driver = new ChromeDriver(capabilities)

We then use the following code in a geb.report.Reporter implementation to extract these logs:

reportState.browser.config.driver.manage().logs().get(LogType.BROWSER).all

Not sure if I am facing the same issue, but with update to Geb 4.0, and
subsequent fine-tuning of logging dependencies
(removing SLF4J-Implementation), we would get a lot of logging output,
because Logback, which is pulled in by Geb,
apparently logs at DEBUG level by default.

I solved this problem for us, by creating a basic logback.xml
configuration file, setting the"root level" to INFO.

Cheers,
Thomas

hi Thomas,

exactly, somewhere DEBUG level is set and only traffic log entries appear, huge amount of them, making logs useless and setting the following in GebConfig

LoggingPreferences logPrefs = new LoggingPreferences()

logPrefs.enable(LogType.BROWSER, Level.ALL)
logPrefs.enable(LogType.CLIENT, Level.SEVERE)
logPrefs.enable(LogType.DRIVER, Level.SEVERE)
logPrefs.enable(LogType.PERFORMANCE, Level.ALL)
logPrefs.enable(LogType.SERVER, Level.SEVERE)
caps.setCapability(CapabilityType.LOGGING_PREFS, logPrefs)

is not considered or used at all.

where is DEBUG set and where exactly did you create the mentioned logback.xml?

could you please post details of the file content too?

after setting this do you get selenium's logs?

thank you!

Create a file src/test/resources/logback.xml, with this content:


<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="INFO">
<appender-ref ref="STDOUT" />
</root>
</configuration>

great, thank you!

I set this as you wrote, traffic log entries do not appear anymore, but why is this

LoggingPreferences logPrefs = new LoggingPreferences()

logPrefs.enable(LogType.BROWSER, Level.ALL)
logPrefs.enable(LogType.CLIENT, Level.SEVERE)
logPrefs.enable(LogType.DRIVER, Level.SEVERE)
logPrefs.enable(LogType.PERFORMANCE, Level.ALL)
logPrefs.enable(LogType.SERVER, Level.SEVERE)
caps.setCapability(CapabilityType.LOGGING_PREFS, logPrefs)

ignored at all?

where does this need to be set?

We then use the following code in a geb.report.Reporter implementation to extract these logs:
reportState.browser.config.driver.manage().logs().get(LogType.BROWSER).all

Yes, logback has unintentionally leaked as a dependency of Geb 4.0. It was never a conscious decision to include it - in my opinion libraries should not bring SLF4J implementations (like logback) and it should always be up to consumer to select one if they so wish. In Geb's case logback is a transitive dependency of org.jodd:jodd-lagarto. This has been rectified in Geb 4.1 and logback is no longer a dependency - it's excluded from org.jodd:jodd-lagarto transitive dependencies in Geb's pom file.

These are two separate things. Logback, on which Thomas has picked up, is used on the client side (inside of your test JVM) and the traffic log entires are made by Selenium in your tests. The configuration that you are using is for logging inside of the browser and if you want these logs logged on the client side then you actually need to retrieve as shown in the SO answer at https://stackoverflow.com/a/25431419/1856764 and then log it.

Hi Marcin,
this is exactly what I figured, and had explained to my coworkers almost
word for word, also pointing to the transitive dependency.
Thanks for the update!
