Each test for me costs about $350, WPS, testing for the API stuff. Probably about a grand or better for API if you do 12 on 12 branch and butt. ASME that I just checked on for say, carbon steel will run me around $700-900. If they supply a CWI to monitor my test, check amps, etc., $900. If I do it myself then $700. AWS, think it was around $350 for wps and testing on 3g/4g. That's at the lab I use though, might be cheaper in different locations, different labs and so on.
