21 * Create an empty test file and run the SPI flash tests. This is a
22 * long way from being a unit test, but it does test SPI device and
23 * emulator binding, probing, the SPI flash emulator including
24 * device tree decoding, plus the file-based backing store of SPI.
26 * More targeted tests could be created to perform the above steps
27 * one at a time. This might not increase test coverage much, but
28 * it would make bugs easier to find. It's not clear whether the
29 * benefit is worth the extra complexity.
