No executable show after build

I was working on the “TODO: dynamically assign gpu clock rate in raspberrypi using mailbox interface”.
I added a folder spi with init.c for testing in testsuites and added a spi.yml file in spec/build/testsuites/spi.
I run ./waf command and went to build directory but found no spi.exe. what am i missing to get spi.exe? and is this the right way for testing?

Hopefully you have found 10. BSP Build System — RTEMS Software Engineering 7.1023b8c (8th January 2026) documentation

You need to re-run waf configure after making changes to the spec/build files.
