This works fine on Linux. However, on Mac OS X, the getProcessMaps() method throws an IOException. The exception message is "No such file or directory". I'm using the same version of the JDK on both platforms. I tried using the same version of the JDK on Linux and Mac OS X, but the Mac OS X version of the JDK doesn't even have the LinuxVirtualMachine class. I also tried using the JDK 6 version of the JDK on both platforms, but the LinuxVirtualMachine class is not present in that version of the JDK either. I was wondering if anyone knew of a way to read a process's /​proc/​$pid/​maps file on Mac OS X. I tried using the ProcessBuilder

Three Techniques for Improved Communication and Testing

Anyone who has worked in the software industry for a while can tell you stories about projects that were on the verge of failure. Many initiatives fail even before they reach clients, which is especially disheartening when the failure is fully avoidable.

Using ChatGPT for Test Automation

ChatGPT broke all Internet records by going viral in the first week of its launch. A million users in 5 days are unprecedented. A conversational AI that can answer natural language-based questions and create poems, write movie scripts, write social media posts, write descriptive essays, and do tons of amazing things. Our first thought when we got access to the platform was how to use this amazing platform to make the lives of web and mobile app testers easier. And most importantly, how we can use ChatGPT for automated testing.
