d56dd0b1f8 test/py: support 'memstart =' in u_boot_utils.find_ram_base()
Some archs like MIPS or PPC have a different 'bdinfo' output
than ARM regarding the memory configuration. Also support
'memstart = 0x*' in u_boot_utils.find_ram_base() to make
all tests requiring the RAM base working on those archs.

085e64dd42 test/py: strip VT100 codes from match buffer
Prior to this patch, any VT100 codes emitted by U-Boot are considered part
of a command's output, which often causes tests to fail. For example,
test_env_echo_exists executes printenv, and then considers any text on a
line before an = sign as a valid U-Boot environment variable name. This
includes any VT100 codes emitted. When the test later attempts to use that
variable, the name would be invalid since it includes the VT100 codes.
Solve this by stripping VT100 codes from the match buffer, so they are
never seen by higher level test code.

The codes are still logged unmodified, so that users can expect U-Boot's
exact output without interference. This does clutter the log file a bit.
However, it allows users to see exactly what U-Boot emitted rather than a
modified version, which hopefully is better for debugging. It's also much
simpler to implement, since logging happens as soon as text is received,
and so stripping the VT100 codes from the log would require handling
reception and stripping of partial VT100 codes.

da37f006e7 tests: py: disable main_signon check for printenv cmd
if CONFIG_VERSION_VARIABLE is set, the U-Boot environment
contains a "vers" variable with the current U-Boot version
string. If now "printenv" is called, test/py fails as it
detects the main_sign string, which is in this case correct.

So check only the main_sign as an error, if CONFIG_VERSION_VARIABLE
is not set.

daa69f5f5d test/py: dfu: wait for USB device to go away at boot
It can take a while for a host machine to notice that a USB device has
disconnected, and process the change. At the end of the DFU test, we wait
up to 10 seconds for this to happen. This change makes the test wait the
same (up to) 10 seconds at the start of the test for any previously active
USB device-mode session to be cleaned up. Such as session might have been
used to download U-Boot into memory for example; this is certainly true
on my Tegra test systems. This changes should solve the DFU test
intermittency issues I've been seeing on some Tegra devices.

8eb3752446 tests: py: dfu: Add functionality to set different u-boot's dfu env variable
By default (on almost all systems) the dfu env variable, which defines
available alt settings, is named as "dfu_alt_info".

However on some platforms (i.e. Odroid XU3), the 'dfu_alt_info' is concatenated
from other variables - namely 'dfu_alt_boot' and 'dfu_alt_system' at run time
(when one types 'dfu 0 mmc 0' for first time).

'dfu_alt_boot' describes alt settings which depend on boot medium - for example
boot loader's LBA sectors which are different on eMMC and SD card because of e.g.
MBR/GPT.

'dfu_alt_system' describes board agnostic alt settings - like rootfs, kernel.
On such system we can only append/modify this env variable.

Because of the above, we must have way to modify other than "dfu_ale_info"
variable to perform tests.

test_hush_if_test.py executes commands that require large values of
CONFIG_SYS_MAXARGS. Detect cases where the configured value is too low
and skip those tests.

Ideally, this would be implemented inside console.run_command(). However,
the command passed to that function is already a completely formed string,
and determining its argument count usage would require splitting commands
at ;, handling quoting to deal with arguments containing spaces, etc. Even
passing the command as a list wouldn't solve all these issues, since we'd
still need to split commands on ; and deal with cases like "if test ..."
which consumes 0 of the argument count.

38831ca3be test/py: use space to interrupt autoboot
Sending CTRL-C to QEMU's stdin aborts the process, even if stdin is being
used as a serial port (at least in the raspi2 machine with "qemu -serial
stdin"). Avoid sending CTRL-C to U-Boot to prevent it exiting.

I'd originally used CTRL-C to make sure that if the character used to
abort autoboot ended up being treated as part of a command as well, it'd
abort command entry and return the prompt to a known state. However, this
is not needed, since aborting the autoboot eats the character used to do
that.

9725543843 test/py: put "Starting U-Boot" into separate log section
The initial boot of U-Boot happens within the context of the first test
that needs to access the U-Boot console when there is no existing
connection. This keeps all activity nestled within test execution, which
fits well into the pytest model. However, this mingles the U-Boot startup
logs with the execution of some test(s), which hides find the boundary
between the two.

To solve this, wrap the "Starting U-Boot" logic into a separate log
section. If the user wishes, they can simply collapse this log section
when viewing the HTML log, to concentrate purely on the test's own
interaction.

93134e18e8 test/py: handle exceptions in console creation
u_boot_console.exec_attach.get_spawn() performs two steps:
1) Spawn a process to communicate with the serial console.
2) Reset the board so that U-Boot starts running from scratch.

Currently, if an exception happens in step (2), no cleanup is performed on
the process created in step (1). That process stays running and may e.g.
hold serial port locks, or simply continue to read data from the serial
port, thus preventing it from reaching any other process that attempts to
read from the same serial port later. While there is error cleanup code in
u_boot_console_base.ensure_spawned(), this is not triggered since the
exception prevents assignment to self.p there, and hence the exception
handler has no object to operate upon in cleanup_spawn().

Solve this by enhancing u_boot_console.exec_attach.get_spawn() to clean
up any objects it has created.

In theory, u_boot_spawn.Spawn's constructor has a similar issue, so fix
this too.

83357fd5c2 test/py: HTML awesome!
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.

89ab841088 test/py: support running sandbox under gdbserver
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.

Other cases, such as the initial boot-up of U-Boot or when interacting

One benefit of this change is that if U-Boot sandbox fails to start up,

d20e5e976f test/py: Provide custom IDs when parametrizing tests
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.

56382a81f3 test/py: make net test aware of USB and PCI enumeration
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.

be1df82656 test/py: dfu: error out if USB device already exists
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.

e787a58fe2 test/py: make crash detection more robust
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.

f5d196d03e test/py: add DFU test
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.

This enhancement is backwards-compatible; old boardenv contents that don't

before.

test/ums/ is deleted since the Python test now performs the same testing
that it did.

c10eb9d39f test/py: drain console log at the end of any failed test
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.

636f38d83a test/py: move U-Boot respawn trigger to the test core
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.

d314e247e1 test/py: fix timeout to be absolute

data, not on its overall operation. In theory, this could cause the

is the intended mode of operation.

d201506cca test/py: Implement pytest infrastructure
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.
