Make test_onroad stressful

[adeebshihadeh]

Now that test_onroad is reliable, it's time to add some things to really stress the system:

• lots of disk load: openpilot shouldn't rely on a responsive disk. catches things like reading params in a real-time loop
• change the system time: catch things like tinygrad/tinygrad@cda34cc

@adeebshihadeh Would writing large files to the disk for the test duration the removing the afterward be what your looking for?

@adeebshihadeh This is what I've got so far.

 def create_disk_load(file_path="temp_file.txt", file_size_mb=50000):

  for _ in range:
    while 0 <= TEST_DURATION:
      file_size_bytes = file_size_mb * 1024 * 1024
      data = os.urandom(file_size_bytes)
      #Create File and Writes/Reads its contents
      try:
        with open(file_path, "wb") as f:
          f.write(data)
        with open(file_path, "rb") as f:
          f.read()
      #Remove File afterwards
      finally:
        try:
          os.remove(file_path)
        except FileNotFoundError:
          # Ignore if the file doesn't exist
          pass

if __name__ == "__main__":
  create_disk_load()
