[PATCH 00/30] test: Refactor tests to have a single test runner

[PATCH 00/30] test: Refactor tests to have a single test runner

[Simon Glass]

At present U-Boot has two broad sets of tests in the C code: driver model
tests which do a lot of pre-/post-init and command tests which do not.

This separation makes it slightly harder to write a test, since there are
two different test-state structures and different rules for running the
two different test types. At present these rules are determined by where
the test is (actually its prefix).

All unit tests can be run from the command line with the 'ut' command.
Since SPL does not have commands, it currently calls the test runner
directly and offers no control of which tests are run.

This seems like a good time to refactor the tests into a unified test
runner, allowing U-Boot proper and SPL to use the same path, perhaps with
some different conditions along the way.

This series sets up a unified runner called ut_run_list(), which runs a
set of tests from a linker_list. Driver model tests are distinguished by
a new UT_TESTF_DM flag so that the necessary init and cleanup can still
be done.

This should make it easier to add SPL tests. A future series may tweak
those as well.

This series is available at u-boot-dm/test-working

[PATCH 04/30] doc: Explain how to run tests without pytest

[Simon Glass]

Add details about how to run a sandbox test directly, without using
pytest. This is more convenient for rapid development, since it is faster
and allows easier use of a debugger. Also mention sandbox_flattree as an
example of the different sandbox builds available.

+Tests Under the Hood
+====================
+
+Running sandbox tests directly
+------------------------------
+
+Typically tests are run using the pytest suite. This is easy and always gets
+things right.
+
+But it is also possible to run some sandbox tests directly. For example, this
+runs the dm_test_gpio() test which you can find in test/dm/gpio.c::
+
+   $ ./u-boot -T -c "ut dm gpio"
+
+
+   U-Boot 2021.01
+
+   Model: sandbox
+   DRAM:  128 MiB
+   WDT:   Started with servicing (60s timeout)
+   MMC:   mmc2: 2 (SD), mmc1: 1 (SD), mmc0: 0 (SD)
+   In:    serial
+   Out:   vidconsole
+   Err:   vidconsole
+   Model: sandbox
+   SCSI:
+   Net:   eth0: eth at 10002000, eth5: eth at 10003000, eth3: sbe5, eth6: eth at 10004000
+   Test: dm_test_gpio: gpio.c
+   Test: dm_test_gpio: gpio.c (flat tree)
+   Failures: 0
+
+The -T option tells U-Boot to run with the 'test' devicetree (test.dts) instead
+of -D which selects the normal sandbox.dts - this is necessary because many
+tests rely on things in the test devicetree. If you try running tests without
+-T then you may see failures, like::
+
+   $ ./u-boot -c "ut dm gpio"
+
+
+   U-Boot 2021.01
+
+   DRAM:  128 MiB
+   WDT:   Not found!
+   MMC:
+   In:    serial
+   Out:   serial
+   Err:   serial
+   SCSI:
+   Net:   No ethernet found.
+   Please run with test device tree:
+       ./u-boot -d arch/sandbox/dts/test.dtb
+   Test: dm_test_gpio: gpio.c
+   test/dm/gpio.c:37, dm_test_gpio(): 0 == gpio_lookup_name("b4", &dev, &offset, &gpio): Expected 0x0 (0), got 0xffffffea (-22)
+   Test: dm_test_gpio: gpio.c (flat tree)
+   test/dm/gpio.c:37, dm_test_gpio(): 0 == gpio_lookup_name("b4", &dev, &offset, &gpio): Expected 0x0 (0), got 0xffffffea (-22)
+   Failures: 2
+
+The message above should provide a hint if you forget. Even running with -D
+will produce different results.
+
+You can easily use gdb on these tests, without needing --gdbserver::
+
+   $ gdb u-boot --args -T -c "ut dm gpio"
+   ...
+   (gdb) break dm_test_gpio
+   Breakpoint 1 at 0x1415bd: file test/dm/gpio.c, line 37.
+   (gdb) run -T -c "ut dm gpio"
+   Starting program: u-boot -T -c "ut dm gpio"
+   Test: dm_test_gpio: gpio.c
+
+   Breakpoint 1, dm_test_gpio (uts=0x5555558029a0 <global_dm_test_state>)
+       at files/test/dm/gpio.c:37
+   37		ut_assertok(gpio_lookup_name("b4", &dev, &offset, &gpio));
+   (gdb)
+
+You can then single-step and look at variables as needed.

+
+Note that after running, SPL continues to boot into U-Boot proper. You can add
+'-c exit' to make U-Boot quit without doing anything further. It is not
+currently possible to run SPL tests and then stop, since the pytests require
+that U-Boot produces the expected banner.
+
+Of course you can use gdb with sandbox_spl, just as with sandbox.
+
+
+What tests are built in?
+------------------------
+
+Whatever sandbox build is used, which tests are present is determined by which
+source files are built. For sandbox_spl, the of_platdata tests are built
+because of the build rule in test/dm/Makefile::
+
+   ifeq ($(CONFIG_SPL_BUILD),y)
+   obj-$(CONFIG_SPL_OF_PLATDATA) += of_platdata.o
+   else
+   ...other tests for non-spl
+   endif

[PATCH 06/30] test: Correct setexpr test prefix

[Simon Glass]

This prefix should be for setexpr, not mem. This means that trying to
select just these tests to run does not work. Fix it.

For some reason this provokes an assertion failure due to memory not
being freed. Move the env_set() in setexpr_test_str() to before the
malloc() heap size size is recorded and disable the rest in
setexpr_test_str_oper().

[PATCH 08/30] test: Rename test-main.c to test-dm.c

[Simon Glass]

This is the main test function for driver model but not for other tests.
Rename the file and the function so this is clear.

[PATCH 09/30] test: Add an overall test runner

[Simon Glass]

Add a new test runner that will eventually be able to run any test. For
now, have it run the 'command' unit tests, so that the functionality in
cmd_ut_category() moves into it.

[PATCH 11/30] test: Call test_pre/post_run() from driver model tests

[Simon Glass]

Ultimately we want to get rid of the special driver model test init and
use test_pre_run() and test_post_run() for all tests. As a first step,
use those function to handle console recording.

For now we need a special case for setting uts->start, but that wil go
away once all init is in one place.

[PATCH 18/30] test: Handle driver model reinit in test_pre_run()

[Simon Glass]

For driver model tests we want to reinit the data structures so that
everything is in a known state before the test runs. This avoids one test
changing something that breaks a subsequent tests.

Move the call for this into test_pre_run().

[PATCH 19/30] test: Drop struct dm_test_state

[Simon Glass]

Driver model is a core part of U-Boot. We don't really need to have a
separate test structure for the driver model tests and it makes it harder
to write a test if you have to think about which type of test it is.

Subsume the fields from struct dm_test_state into struct unit_test_state
and delete the former.

[PATCH 25/30] test: Add ut_run_test_live_flat() to run tests twice

[Simon Glass]

Driver model tests are generally run twice, once with livetree enable and
again with it disabled. Add a function to handle this and call it from the
driver model test runner.

Make ut_run_test() private since it is not used outside test-main.c now.

[PATCH 26/30] test: Use a local variable for test state

[Simon Glass]

At present we use a global test state for all driver-model tests. Make use
of a local struct like we do with the other tests.

To make this work, add functions to get and set this state. When a test
starts, the state is set (so it can be used in the test). When a test
finishes, the state is unset, so it cannot be used by mistake.

[PATCH 28/30] test: Use return values in dm_test_run()

[Simon Glass]

Update this function to use the return value of ut_run_list() to check for
success/failure, so that they are in sync. Also return a command success
code so that the caller gets what it expects.

[PATCH 29/30] test: Move the devicetree check into ut_run_list()

[Simon Glass]

Add a check to ut_run_list() as to whether a list has driver model tests.
Move the logic for the test devicetree into that function, in an effort
to eventually remove all logic from dm_test_run().

Proper reStructered text style would be

test/fs
    File system test (shell script)

test/image
    FIT and legacy image tests (shell script and Python)

The first line of each paragraph will be in bold.
