Some developers use the gs.addInfoMessage() or gs.addErrorMessage() JavaScript methods, but these may have an impact on the user experience. Gs.print() and gs.log() are older and not available in scoped applications, whereas gs.debug(), gs.info(), gs.warn(), gs.error() work in both scoped applications and global are therefore are more versatile going forward in future versions.Īnother helpful function gs.isDebugging() and can be used to determine if session debugging is on OR the scoped property is debug. If a tester or user reports that something is not behaving as expected in test, QA, production, or another instance, you can enable the property, enable debugging output, and investigate your results quickly. When combined with Debug Log or Debug Business Rule, this property can be used to enable or disable debug information without changing code and without impacting the user experiences of others on the system. If it is set to true, the debug message will be displayed. If the system property debug.MyUtil is set to false, nothing will be output to the log. They can be turned on and off the debug property in the script include with a property so you don’t have to modify code in production to enable/disable debugging.Ī common use case is a debug function in a script include that checks the value of a specific system property to determine if it should output the message indicated. It enables you to have distinct debugging in script includes so they can each be debugged independent of each other. The recommended way to debug server-side scripts is to use gs.debug() statements controlled by system properties. the session expires (for example, the session times out).you activate the Stop Debugging module, located in System Security.When you activate a server-side debugging module, it remains active until one of the following occurs: System Security > Stop Debugging disables all debugging processes. The debug security rules have enhanced functionality, allowing you to view a context parameter. This module is very helpful when you are using ACLs to control access to records and fields. Click the icon to expand details about read and write access. Point to the icon to see if there are any debug messages for the associated element. These messages indicate which business rules are being run and when they are started (=>), finished ( Debug Security Rules places a debug icon on each field of a form. System Diagnostics > Debug Business Rule displays messages about business rules. However, gs.print() and gs.log() are not available in scoped applications, whereas gs.debug() and gs.info() work in both scoped applications and global and are often used instead. This helps you avoid alternating between the record you are trying to debug and the log output. System Diagnostics > Debug Log displays gs.debug(), gs.info(), gs.print() and gs.log() statements as well as server logging information and error messages at the bottom of the content frame. For most but not all debugging features, when the debugging feature is active, and area labeled Debug Output appears at the bottom of the content frame. Enter debug in the navigation filter to display all debugging modules. the steps required to reproduce the issueīefore starting work on an implementation, consider using one or more of the system debugging modules in the System Diagnostics and System Security applications. the user ID used for the test - for example, Change Test User 3.the record being worked on - for example, CHG0012513.To help identify and remediate the issue, the tester should provide the following information: Potential sources include user error, invalid test data, test script inaccuracy, and technical implementation. Client-side practices.īefore you start debugging, it is important to identify the source of the issue, and to be able to reproduce the defect or bug. See the original article on the ServiceNow doc site: Debugging Best Practices Overview.ĭebugging can provide information to help you understand system processes. Debugging best practices can be classified into two main areas: Server-side vs. This article is based on the ServiceNow documentation article.
