appium-xcuitest-driver missing debug logs in syslog for simulators

[johanblumenberg]

The problem

I am testing a react-native application on the iOS simulator. react-native is forwarding all console logs to syslog, on the appropriate level. I am trying to collect my application log from my tests.

appium-xcuitest-driver has the capability to capture syslog. However, when I read the log files, I can only see logs on Error level. Nothing on Debug or Info level is logged.

This is the code that spawns the log capture process: https://github.com/appium/appium-xcuitest-driver/blob/21ab45fec87ba986820188e7bf4666d6915df6c0/lib/device-log/ios-simulator-log.js#L28 By adding --debug to the log stream command I can make appium-xcuitest-driver include all log levels in the collected logs.

Environment

• Appium version (or git revision) that exhibits the issue: 1.22.3
• Last Appium version that did not exhibit the issue (if applicable): N/A
• Driver version that exhibits the issue (only for Appium2): N/A
• Last driver version that did not exhibit the issue (if applicable, only for Appium2): N/A
• Desktop OS/version used to run Appium: OSX 12.3.1
• Node.js version (unless using Appium.app|exe): v16.13.1
• Package manager name and version (we only officially support NPM): yarn
• Mobile platform/version under test: iOS 15.2
• Real device or emulator/simulator: iPhone 13 simulator
• Appium CLI or Appium.app|exe: Appium CLI

Seems like a great candidate for a pull request to me! (Maybe hidden behind a capability showIosDebugSyslogs or something like that)

I assume it's simulator-specific as real devices use a separate logic branch to fetch logs

Hi @mykola-mokhnach ,

In android I am able to fetch the application's API logs present in debug mode but I am not able to fetch the same debug log in iOS, using "syslog". is it any way to fetch debug logs?? It would be very helpful.

@AYUSH-17 Within a Simulator i can write iOS sysLogs with this to a file : PrintWriter log_file_writer = new PrintWriter(saveDir_syslog); LogEntries logs = driver.manage().logs().get("syslog"); StreamSupport.stream(logs.spliterator(), false).forEach(logXY ->{log_file_writer.println(logXY);}); log_file_writer.flush(); log_file_writer.close();

But my logs show only "ALL" log category. Don't know if this are intresting informations or if there are "DEBUG" log category included

Hi @StephanB75 , I am running my test cases on real devices(iOS) as the application that I am using is not compatible with simulator. I am able to capture the syslog but log that I am searching is present only in debug mode.
