Class JavaScriptDebugger

java.lang.Object
  org.jvnet.hudson.test.rhino.JavaScriptDebugger

All Implemented Interfaces:

net.sourceforge.htmlunit.corejs.javascript.debug.Debugger

public class JavaScriptDebugger
extends Object
implements net.sourceforge.htmlunit.corejs.javascript.debug.Debugger

Monitors the execution of the JavaScript inside HtmlUnit, and provides debug information such as call stacks, variables, arguments, etc.

Usage

When you set a break point in Java code that are directly/indirectly invoked through JavaScript, use toString() to see the JavaScript stack trace (and variables at each stack frame.) This helps you see where the problem is.

TODO: add programmatic break point API, selective method invocation tracing, and allow arbitrary script evaluation in arbitrary stack frame.
