Test All Makefile Targets

What I do

• Start at the current directory and search through all subdirectories for Makefiles
  • find . -name "Makefile" -type "f"
• Make a list of the targets in each makefile that only affect the user's host
• Only test one Makefile at a time
  • Start with the Makefile closest to the root directory and work further from the root directory
• Run each target in dry-run mode
  • If the result of the dry-run of the target is non-zero, report that result as a failure
  • If the result of the dry-run of the target is zero, report that result as a success
• For the targets that only affect the user's host, run each target
  • If the result of the target is non-zero, report that result as a failure
  • If the result of the target is zero, report that result as a success
  • If there are targets that build docker images, ask how long the user would like to wait for the docker build to complete and use that as a timeout for any make targets that invoke a docker build
• When a target fails, continue testing the remaining targets
• Generate a detailed report of which targets passed and which targets failed, including the error messages for the failed targets
