Currently, bad patterns are only honored when executing a shell command.
Other cases, such as the initial boot-up of U-Boot or when interacting
with command output rather than gathering all output prior to the shell
prompt, do not currently look for bad patterns in console output. This
patch makes sure that bad patterns are honored everywhere.
One benefit of this change is that if U-Boot sandbox fails to start up,
the error message it emits can be caught immediately, rather than relying
on a (long) timeout when waiting for the expected signon message and/or
command prompt.

A future patch will use the bad_patterns array in multiple places. Rather
than duplicating the code to calculate it, or even sharing it in a
function and simply calling it redundantly when nothing has changed, only
re-calculate the list when some change is made to it. This reduces work.

Multiple patterns may be passed to spawn.expect(). The pattern which
matches at the earliest position should be designated as the match. This
aspect works correctly. When multiple patterns match at the same position,
priority should be given the the earliest entry in the list of patterns.
This aspect does not work correctly. This patch fixes it.

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.

The existing net test executes a list of commands supplied by boardenv
variable env__net_pre_commands. The idea was that boardenv would know
whether the Ethernet device was attached to USB, PCI, ... and hence was
the best place to put any commands required to probe the device.
However, this approach doesn't scale well when attempting to use a single
boardenv across multiple branches of U-Boot, some of which require "pci
enum" to enumerate PCI and others of which don't, or don't /yet/ simply
because various upstream changes haven't been merged down.
This patch updates the test to require that the boardenv state which HW
features are required for Ethernet to work, and lets the test itself map
that knowledge to the set of commands to execute. Since this mapping is
part of the test script, which is part of the U-Boot code/branch, this
approach is more scalable. It also feels cleaner, since again boardenv
is only providing data, rather than test logic.

The DFU test requests U-Boot configure its USB controller in device mode,
then waits for the host machine to enumerate the USB device and create a
device node for it. However, this wait can be fooled if the USB device
node already exists before the test starts, e.g. if some previous software
stack already configured the USB controller into device mode and never
de-configured it. This "previous software stack" could even be another
test/py test, if U-Boot's own USB teardown does not operate correctly. If
this happens, dfu-util may be run before U-Boot is ready to serve DFU
commands, which may cause false test failures.
Enhance the dfu test to fail if the device node exists before it is
expected to.

test/py contains logic to detect the target crashing and rebooting by
searching the console output for a U-Boot signon message, which will
presumably be emitted when the system boots after the crash/reset.
Currently, this logic only searches for the exact signon message that
was printed by the U-Boot version under test, upon the assumption that
binary is written into flash, and hence will be the version booted after
any reset. However, this is not a valid assumption; some test setups
download the U-Boot-under-test into RAM and boot it from there, and in
such a scenario an arbitrary U-Boot version may be located in flash and
hence run after any reset.
Fix the reset detection logic to match any U-Boot signon message. This
prevents false negatives.

Add a test of DFU functionality to the Python test suite. The test
starts DFU in U-Boot, waits for USB device enumeration on the host,
executes dfu-util multiple times to test various transfer sizes, many
of which trigger USB driver edge cases, and finally aborts the DFU
command in U-Boot.
This test mirrors the functionality previously available via the shell
scripts in test/dfu, and hence those are removed too.

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

Tests may fail for a number of reasons, and in particular for reasons
other than a timeout waiting for U-Boot to print expected data. If the
last operation that a failed test performs is not waiting for U-Boot to
print something, then any trailing output from U-Boot during that test's
operation will not be logged as part of that test, but rather either
along with the next test, or even thrown away, potentiall hiding clues
re: the test failure reason.
Solve this by explicitly draining (and hence logging) the U-Boot output
in the case of failed tests.

Prior to this change, U-Boot was lazilly (re-)spawned if/when a test
attempted to interact with it, and no active connection existed. This
approach was simple, yet had the disadvantage that U-Boot might be
spawned in the middle of a test function, e.g. after the test had already
performed actions such as creating data files, etc. In that case, this
could cause the log to contain the sequence (1) some test logs, (2)
U-Boot's boot process, (3) the rest of that test's logs. This isn't
optimally readable. This issue will affect the upcoming DFU and enhanced
UMS tests.
This change converts u_boot_console to be a function-scoped fixture, so
that pytest attempts to re-create the object for each test invocation.
This allows the fixture factory function to ensure that U-Boot is spawned
prior to every test. In practice, the same object is returned each time
so there is essentially no additional overhead due to this change.
This allows us to remove:
- The explicit ensure_spawned() call from test_sleep, since the core now
ensures that the spawn happens before the test code is executed.
- The laxy calls to ensure_spawned() in the u_boot_console_*
implementations.
The one downside is that test_env's "state_ttest_env" fixture must be
converted to a function-scoped fixture too, since a module-scoped fixture
cannot use a function-scoped fixture. To avoid overhead, we use the same
trick of returning the same object each time.

Currently, Spawn.expect() imposes its timeout solely upon receipt of new
data, not on its overall operation. In theory, this could cause the
timeout not to fire if U-Boot continually generated output that did not
match the expected patterns.

is the intended mode of operation.

This tool aims to test U-Boot by executing U-Boot shell commands using the
console interface. A single top-level script exists to execute or attach
to the U-Boot console, run the entire script of tests against it, and
summarize the results. Advantages of this approach are:
- Testing is performed in the same way a user or script would interact
with U-Boot; there can be no disconnect.
- There is no need to write or embed test-related code into U-Boot itself.
It is asserted that writing test-related code in Python is simpler and
more flexible that writing it all in C.
- It is reasonably simple to interact with U-Boot in this way.
A few simple tests are provided as examples. Soon, we should convert as
many as possible of the other tests in test/* and test/cmd_ut.c too.
The hook scripts, relay control utilities, and udev rules I use for my
own HW setup are published at https://github.com/swarren/uboot-test-hooks.
