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