Let us go through what these different pieces of information mean and how they can be used:

• Call Stack: This is the list of script calls that preceded or invoked the current line (where the script is paused). It is useful to determine the flow of the execution and whether the flow is affecting any data or data validation, and so on:

• Transaction Detail: This section contains a list of useful information such as the URL of the page, request parameters, (get and post) variables and their values, and instance and session details, and can be used to debug the values being passed from the form:

• Variables: The following three variable sections are available, segregated by scope, and are very useful when performing step over, step into, or step out as they can help monitor the list of available variables and changes to their values:
  • Local: This section lists all the local scope variables and their values
  • Closures: This section lists all the function scope variables and their values set and accessible within the function closures
  • Global: This section lists all the global scope variables and their values
