Mastering ServiceNow Scripting

By: Andrew Kindred

Overview of this book

Industry giants like RedHat and NetApp have adopted ServiceNow for their operational needs, and it is evolving as the number one platform choice for IT Service management. ServiceNow provides their clients with an add-on when it comes to baseline instances, where scripting can be used to customize and improve the performance of instances. It also provides inbuilt JavaScript API for scripting and improving your JavaScript instance. This book will initially cover the basics of ServiceNow scripting and the appropriate time to script in a ServiceNow environment. Then, we dig deeper into client-side and server-side scripting using JavaScipt API. We will also cover advance concepts like on-demand functions, script actions, and best practices. Mastering ServiceNow Scripting acts as an end-to-end guide for writing, testing, and debugging scripts of ServiceNow. We cover update sets for moving customizations between ServiceNow instances, jelly scripts for making custom pages, and best practices for all types of script in ServiceNow. By the end of this book, you will have hands-on experience in scripting ServiceNow using inbuilt JavaScript API.

Therefore, it is extremely important that any application is thoroughly tested before it is deployed. 

When testing a new custom application, it is important to also test around the application as well as the application itself. This means do not just test that the application works, also test that any applications the new application is linked or related to also still functions in the way it did before. This is particularly important when dealing with access controls and security, and always ensure that no access is granted that should not be and that existing users of an application are not locked out of data they had access to before.

If we do come across issues when performing our testing, it is worth remembering the techniques that...
