Software testing is not a profession in the legal sense, so you may not be able to find this data from the states Department of Labor. I suspect the closest you will find is on a site like Glassdoor where people are willing to anonymously document their salary.
What is the avge price per hour for sw manual functional test in California and in Texas plesa
I have to prepare a presentation comparing both States: California vs Texas, and although there is tons of information about cost differences, I have not found any information about software testing price differences. I imagine it is higher in California but is it high enough to compensate the cost differences?
