my thoughts on test automation
If copy & paste doesn’t work for you in JMeter on OS X
If copy & paste doesn’t work for you in JMeter running on OS X, check if you didn’t corrupt .properties files in <jmeter_dir>/bin folder. If you override those with command line parameters, ensure you override the right ones. It is important to load certain files with certain command line switches, as described by ./jmeter.sh -help output. If you mix them, you can face strange issues.
Anyway, if copy & paste still doesn’t work for you, check not only CMD+C/V, but also CTRL+C/V and right-click menu. There is a chance one of them will be working for you 🙂
(for those who are not familiar with OS X: in most cases CMD button is used instead of CTRL on this platform)
