At present the collection function used by pytest is quite strict on the
naming of the functions it detects. In particular it requires the name of
the test to be repeated in the function name.
This is not enforced anywhere else, but instead the tests are silently
omitted from the pytest run. This affects a few dozen tests.
The rule does not seem to have any particular purpose. Relax it, so that
all tests that use the UNIT_TEST() macro will run, regardless of the name
of the test function.

Improve the regular expression that matches unittest symbols in
u-boot.sym.
Currently we do not enforce no prefix in symbol string, but with the
soon to come change in linker lists declaring lists and entries with the
__ADDRESSABLE macro (because of LTO), the symbol file will contain for
every symbol of the form
_u_boot_list_2_ut_X_2_Y
also symbol
__UNIQUE_ID___addressable__u_boot_list_2_ut_X_2_YN,
(where N at the end is some number).
In order to avoid matching these additional symbols, ensure that the
character before "_u_boot_list_2_ut" is not a symbol name character.

At present each test suite has its own portion of the linker_list section
of the image, but other lists are interspersed. This makes it hard to
enumerate all the available tests without knowing the suites that each one
is in.

common prefix not used elsewhere in U-Boot. This makes it possible to find

The implementation of pytest_runtest_protocol() must call
pytest_runtest_logstart() and pytest_runtest_logfinish(). This appears to
be necessary even in pytest 5.2.1 judging by the default version of
pytest_runtest_protocol(), but evidently some form of code reorganization
in pytest only made this have a practical effect in the newer version. I'd
previously been under the impression that 100% of the required work of
pytest_runtest_protocol() was handled by the fact it called
runtestprotocol() as its implementation. However, it appears that custom
implementations do need to do a little more than this.

It is a pain to have to set the CROSS_COMPILE environment variable when
using test.py's --build option. It is possible to get this using the -A
option from buildman. But it seems better to just use buildman to do the

However using buildman adds a new dependency to the test system which we
want to avoid. So leave the default as is and add a flag to make it use
buildman.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Implement three improvements to the HTML log file:
- Ability to expand/contract sections. All passing sections are contracted
at file load time so the user can concentrate on issues requiring
action.
- The overall status report is copied to the top of the log for easy
access.
- Add links from the status report to the test logs, for easy navigation.
This all relies on Javascript and the jquery library. If the user doesn't
have Javascript enabled, or jquery can't be downloaded, the log should
look and behave identically to how it did before this patch.
A few notes on the diff:
- A few more 'with log.section("xxx")' were added, so that all stream
blocks are kept within a section block for consistent HTML entity
nesting structure. This changed indentation in a few places, making
the diff look slightly larger.
- HTML entity IDs are cleaned up. We assign simple incrementing integer
IDs now, rather than using mangled test names which were possibly
invalid.
- Sections and streams now use common CSS class names (in addition to the
current separate class names) to more easily share the new behaviour.
This also reduces the CSS file size since rules don't need to be
duplicated.
- An "OK" status is logged after some external command executions so that
make and flash steps are auto-contracted at log file load time, assuming
they passed.

Implement command--line option --gdbserver COMM, which does two things:
a) Run the sandbox process under gdbserver, using COMM as gdbserver's
communication channel.
b) Disables all timeouts, so that if U-Boot is halted under the debugger,
tests don't fail. If the user gives up in the middle of a debugging
session, they can simply CTRL-C the test script to abort it.
This allows easy debugging of test failures without having to manually
re-create the failure conditions. Usage is:
Window 1:
./test/py/test.py --bd sandbox --gdbserver localhost:1234
Window 2:
gdb ./build-sandbox/u-boot -ex 'target remote localhost:1234'
When using this option, it likely makes sense to use pytest's -k option
to limit the set of tests that are executed.
Simply running U-Boot directly under gdb (rather than gdbserver) was
also considered. However, this was rejected because:
a) gdb's output would then be processed by the test script, and likely
confuse it causing false failures.
b) pytest by default hides stdout from tests, which would prevent the
user from interacting with gdb.
While gdb can be told to redirect the debugee's stdio to a separate
PTY, this would appear to leave gdb's stdio directed at the test
scripts and the debugee's stdio directed elsewhere, which is the
opposite of the desired effect. Perhaps some complicated PTY muxing
and process hierarchy could invert this. However, the current scheme
is simple to implement and use, so it doesn't seem worth complicating
matters.
c) Using gdbserver allows arbitrary debuggers to be used, even those with
a GUI. If the test scripts invoked the debugger themselves, they'd have
to know how to execute arbitary applications. While the user could hide
this all in a wrapper script, this feels like extra complication.
An interesting future idea might be a --gdb-screen option, which could
spawn both U-Boot and gdb separately, and spawn the screen into a newly
created window under screen. Similar options could be envisaged for
creating a new xterm/... too.
--gdbserver currently only supports sandbox, and not real hardware.
That's primarily because the test hooks are responsible for all aspects of
hardware control, so there's nothing for the test scripts themselves can
do to enable gdbserver on real hardware. We might consider introducing a
separate --disable-timeouts option to support use of debuggers on real
hardware, and having --gdbserver imply that option.

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.

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.

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.

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.
