Resolving Jenkins WebDriver Browser Visibility and Real-Time Python Print Logging Issues

When Jenkins invokes Python's WebDriver, the browser runs in the background and cannot be displayed on the screen, and Python's print statements do not flush to the console in real time.

Solution 1 for Jenkins: Run Jenkins with administrator privileges, delete the existing Windows service using sc delete jenkins , then start Jenkins directly with java -jar jenkins.war (reboot if necessary). This allows the browser to run in the foreground.

Solution 2 for Jenkins: Deploy Jenkins as a WAR file inside Tomcat running under an administrator account. By avoiding the default SYSTEM user, WebDriver launches the browser in the visible foreground, making it behave like a local debug session.

Solution for Python print logging:

1) Add sys.stdout.flush() after each print call.

2) Reassign sys.stdout with sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0) to disable buffering.

3) Run the Python script with the -u flag (unbuffered mode) to ensure immediate console output.
