Package org.jvnet.hudson.test.rhino

Class JavaScriptDebugger

java.lang.Object
org.jvnet.hudson.test.rhino.JavaScriptDebugger
All Implemented Interfaces:
org.htmlunit.corejs.javascript.debug.Debugger
public class JavaScriptDebugger extends Object implements org.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.
