[naresh1019]

Hello Guys,

Do we have proper debugging Methods to test ClientSide/Server Side SCripts.

Basically I am from JAVA background, there we have a good IDE where we can get all the information, So I would like to know do

Hello

Script debugger

The Script Debugger allows application developers to debug server-side JavaScript.

The Script Debugger allows each application developer to:

• Have a dedicated debug transaction, which only applies to the current session.
• Set and remove breakpoints.
• Pause the current session at a breakpoint.
• Step through code line-by-line.
• Step into and out of function and method calls.
• View the value of local and global variables.
• View the value of private variables from function closures.
• View the call stack.
• View the transaction the system is processing.
• Turn off the script debugger to resume running paused scripts.

The Script Debugger can pause any server-side script that runs in an interactive transaction such as business rules, script includes, script actions, or UI actions that require a response in order to proceed. If the GlideSystem method isInteractive() would return true when running the script in context, then the Script Debugger can pause it.

Note: Some script objects such as script includes can be called from multiple contexts. When a business rule runs a script include on form submit that is an interactive transaction waiting on the form data to change before continuing. When a scheduled job runs the same script include that is a non-interactive background transaction that can also run other scripts simultaneously.
To debug client-side script, you can use browser-based developers tools.

Note: For information about using Chrome to debug client-side scripts, see the blog post Using Chrome to Debug Client Side Errors by a ServiceNow Technical Support Engineer in the ServiceNow Community.

Only users with the script_debugger role can access the Script Debugger.A debugger transaction remains open as long as the user session is valid. If a user session logs out or times out, the system closes the debugger transaction.

• Parts of the Script Debugger interfaceThe Script Debugger interface displays information about breakpoints set, the call stack and line number of the currently executing script line, and details about variables and transactions.
• Script Debugger step-through controlsAfter the Script Debugger pauses a script, use the step-through controls to move between script lines and move between scripts in the call stack.
• Launch the Script DebuggerDevelopers can launch the Script Debugger from the application navigator, Studio, or from the syntax editor.
• Set or remove breakpointsSet breakpoints to pause scripts at specific lines, and remove breakpoints when you are done debugging them.
• Script Debugger statusThe Script Debugger status determines what debugging actions are available and what information it can display.
• Transaction detailsThe Script Debugger displays transaction details for the current paused user session.
• Available transaction detailsThe Script Debugger provides a standard set of transaction details for developers to debug and troubleshoot scripts.
• Script Debugger multiple developer supportThe Script Debugger allows multiple developers to debug their own transactions without affecting each other.
• Script Debugger impersonation supportYou can use the Script Debugger while impersonating another user, but only if the impersonated user has the script_debugger role and has read access to the target script.
• Script Debugger Scripts - Background supportThe Scripts - Background module does not support setting breakpoints directly in the script field. You can however, set breakpoints in the script objects called or triggered by the Scripts - Background module.
