Running and Debugging Applications
When you test your applications in Adobe® Flex® Builder™, you run the application SWF files in a web browser or the stand-alone Flash Player. If you encounter errors in your applications, you use the debugging tools to set and manage breakpoints in your code; control application execution by suspending, resuming, and terminating the application; step into and over the code statements, select critical variables to watch, and evaluate watch expressions while the application runs.
