* test/py: Provide custom IDs when parametrizing testsStephen Warren2016-01-28-0/+3
| | | | | | | | | | | | | | | | | | | | | When pytest generates the name for parametrized tests, simple parameter values (ints, strings) get used directly, but more complex values such as dicts are not handled. This yields test names such as: dfu[env__usb_dev_port0-env__dfu_config0] dfu[env__usb_dev_port0-env__dfu_config1] Add some code to extract a custom fixture ID from the fixture values, so that we end up with meaningful names such as: dfu[micro_b-emmc] dfu[devport2-ram] If the boardenv file doesn't define custom names, the code falls back to the old algorithm.

* test/py: use " for docstringsStephen Warren2016-01-28-12/+12
| | | | | | | | | | | Python's coding style docs indicate to use " not ' for docstrings. test/py has other violations of the coding style docs, since the docs specify a stranger style than I would expect, but nobody has complained about those yet:-) Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* test/py: ums: add filesystem-based testingStephen Warren2016-01-28-48/+188
| | | | | | | | | | | | | | | | | | | | | Enhance the UMS test to optionally mount a partition and read/write a file to it, validating that the content written and read back are identical. This enhancement is backwards-compatible; old boardenv contents that don't define the new configuration data will cause the test code to perform as before. test/ums/ is deleted since the Python test now performs the same testing that it did. The code is also re-written to make use of the recently added utility module, and split it up into nested functions so the overall logic of the test process can be followed more easily without the details cluttering the code.

* test/py: test the ums commandStephen Warren2016-01-20-0/+94
This test invokes the "ums" command in U-Boot, and validates that a USB storage device is enumerated on the test host system, and can be read from. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>
