2017-09-29test/py: add skip marker for reliance on toolsStephen Warren
Some tests use external tools (executables) during their operation. Add a test.py mark to indicate this. This allows those tests to be skipped if the required tool is not present. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2017-07-22tests: test_dfu.py: Add example udev rule for host_usb_dev_nodeTom Rini
If one does not already have a rule to create a custom device node when a given device enumerates it can be useful to have udev create a bus path based node to the entry in /dev/bus/usb that was just enumerated. Given that DFU itself does not require a /dev entry it is a good idea to provide a rule that will generate one. Signed-off-by: Tom Rini <trini@konsulko.com>
2016-05-06test/py: dfu: wait for USB device to go away at bootStephen Warren
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. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2016-04-25tests: py: dfu: Provide functionality to set test and dummy files alt settingsLukasz Majewski
After concatenation of "dfu_alt_info" variable from "dfu_alt_boot" and "dfu_alt_system" it may happen that test and dummy files alt settings are different than default 0 and 1. This patch provides the ability to set different values for them. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Acked-by: Stephen Warren <swarren@nvidia.com> --- Changes for v3: - replace variables declarations with ones read from configuration file - remove not necessary str() conversion at DFU host command generation Changes for v2: - generate "alt_info" automatically - use file names as alt settings instead of numerical values - extend in-code documentation
2016-04-25tests: py: dfu: Add functionality to set different u-boot's dfu env variableLukasz Majewski
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. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Acked-by: Stephen Warren <swarren@nvidia.com> --- Changes for v3: - None Changes for v2: - Rewrite of "alt_info_env_name" variable description - Use of get() method on python's dictionary to easily obtain default value
2016-04-25tests: py: dfu: Add variables to store dfu alt numbers for test and dummy filesLukasz Majewski
This patch replaces hardcoded (i.e. 0 and 1) values passed to dfu_{read|write} with variables. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Acked-by: Stephen Warren <swarren@nvidia.com> --- Changes for v3: - Replace per module global variables with ones defined inside a function Changes for v2: - None
2016-01-28test/py: dfu: allow boardenv to specify test sizesStephen Warren
Allow the env__dfu_configs boardenv data to specify the set of DFU transfer sizes to test. Manually specifying test sizes is useful if you wish to test multiple DFU configurations (e.g. SD card ext4 filesystem, SD card whole raw partition, RAM, etc.), but don't want to test every single transfer size on each, to avoid bloating the overall time taken by testing. If the boardenv doesn't specify a set of sizes, the built-in list is used as a default, preserving backwards-compatibility.

2016-01-28test/py: Provide custom IDs when parametrizing testsStephen Warren
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.

2016-01-28test/py: Quote consistencyStephen Warren
When converting test/py from " to ', I missed a few places (or added a few inconsistencies later). Fix these. Note that only quotes in code are converted; double-quotes in comments and HTML are left as-is, since English and HTML use " not '.

2016-01-28test/py: use " for docstringsStephen Warren
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>
2016-01-28test/py: dfu: error out if USB device already existsStephen Warren
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. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2016-01-28test/py: add DFU testStephen Warren
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.
