testexport: support for executing tests over serial

2024-09-01T11:28:10+00:00

Uses TEST_SERIALCONTROL_CMD to open a serial connection to the target and execute commands. This is a drop in replacement for the ssh target, fully supporting the same API. Supported with testexport. To use, set the following in local.conf: - TEST_TARGET to "serial" - TEST_SERIALCONTROL_CMD to a shell command or script which connects to the serial console of the target and forwards that connection to standard input/output. - TEST_SERIALCONTROL_EXTRA_ARGS (optional) any parameters that must be passed to the serial control command. - TEST_SERIALCONTROL_PS1 (optional) A regex string representing an empty prompt on the target terminal. Example: "root@target:.*# ". This is used to find an empty shell after each command is run. This field is optional and will default to "root@{MACHINE}:.*# " if no other value is given. - TEST_SERIALCONTROL_CONNECT_TIMEOUT (optional) Specifies the timeout in seconds for the initial connection to the target. Defaults to 10 if no other value is given. The serial target does have some additional limitations over the ssh target. 1. Only supports one "run" command at a time. If two threads attempt to call "run", one will block until it finishes. This is a limitation of the serial link, since two connections cannot be opened at once. 2. For file transfer, the target needs a shell and the base32 program. The file transfer implementation was chosen to be as generic as possible, so it could support as many targets as possible. 3. Transferring files is significantly slower. On a 115200 baud serial connection, the fastest observed speed was 30kbps. This is due to overhead in the implementation due to decisions documented in #2 above.

TEST_SERIALCONTROL_CMD was set to a bash script which connected with telnet to the target. Additionally tested with QEMU by setting TEST_SERIALCONTROL_CMD to "ssh -o StrictHostKeyChecking=no root@192.168.7.2". This imitates a serial connection to the QEMU instance. Steps: 1) Set the following in local.conf: - IMAGE_CLASSES += "testexport" - TEST_TARGET = "serial" - TEST_SERIALCONTROL_CMD="ssh -o StrictHostKeyChecking=no root@192.168.7.2" 2) Build an image - bitbake core-image-sato 3) Run the test export - bitbake -c testexport core-image-sato 4) Run the image in qemu - runqemu nographic core-image-sato 5) Navigate to the test export directory 6) Run the exported tests with target-type set to serial - ./oe-test runtime --test-data-file ./data/testdata.json --packages-manifest ./data/manifest --debug --target-type serial Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

testimage/oeqa: Drop testimage_dump_host functionality

2023-06-29T09:57:27+00:00

The intent behind these functions was to dump the system state when issues occured but it has never really worked as we'd planned. Regular monitoring as the build runs has largely replaced this as that allows a trend to be seen rather than a spot value which was never really useful. The code is bitrotting and not functioning correctly so drop it.

oeqa/runtime/context: remove duplicate sys.path entries when looking for modules

2022-03-26T09:33:32+00:00

sys.path can contain duplicate entries for each layer, which means that the search in add_controller_list() will find the same name twice and abort. As duplicate directories should be harmless, remove any duplicates before iterating through the entries.

oeqa/runtime: search sys.path explicitly for modules

2021-10-23T16:42:28+00:00

The controller module loading code needs to be told what directories to search for modules via the target_modules_path keyword argument, which is set to BBPATH. However, as the actual module loading is done via importlib this relies on the paths being on sys.path, which it is as base.bbclass puts each layer's lib/ in sys.path. Simplify the code by removing this indirection, and simply search sys.path directly.

oeqa: default runtime json results for testexport

2020-03-29T11:05:31+00:00

Set the json result output dir in the oeqe runtime context to create testresults.json file by default for exported runtime test runs. Use current datetime for the json result property name (not DATETIME from build) to allow multiple result entries.

oeqa/runtime/context.py: support listening port in TEST_SERVER_IP

2019-12-16T23:25:49+00:00

Similar to the existing possibility to specify a port in TEST_TARGET_IP, allow TEST_SERVER_IP to also contain a port. The intention is for this port to be passed into e.g. the http server from the apt / dnf / opkg tests, or any other (custom) tests that might need the target to connect to a service spawned by bitbake / oeqa, where bitbake is actually running inside a docker container.

oeqa/runtime/context.py: ignore more files when loading controllers

2019-10-23T15:30:36+00:00

When loading controllers as (external) modules, the code currently tries to load all files ending with .py. This is a problem when during development using an editor that creates a lock-file in the same directory as the .py file, as the lock file is typically called '.#xxxx.py'. Python will try to load the lock file and fail miserably with an exception: The stack trace of python calls that resulted in this exception/failure was: File: 'exec_python_func() autogenerated', lineno: 2, function: 0001: *** 0002:do_testimage(d) 0003: File: 'poky/meta/classes/testimage.bbclass', lineno: 114, function: do_testimage 0110: netstat -an 0111:} 0112: 0113:python do_testimage() { *** 0114: testimage_main(d) 0115:} 0116: 0117:addtask testimage 0118:do_testimage[nostamp] = "1" File: 'poky/meta/classes/testimage.bbclass', lineno: 294, function: testimage_main 0290: 0291: # the robot dance 0292: target = OERuntimeTestContextExecutor.getTarget( 0293: d.getVar("TEST_TARGET"), logger, d.getVar("TEST_TARGET_IP"), *** 0294: d.getVar("TEST_SERVER_IP"), **target_kwargs) 0295: 0296: # test context 0297: tc = OERuntimeTestContext(td, logger, target, host_dumper, 0298: image_packages, extract_dir) File: 'poky/meta/lib/oeqa/runtime/context.py', lineno: 116, function: getTarget 0112: # XXX: Don't base your targets on this code it will be refactored 0113: # in the near future. 0114: # Custom target module loading 0115: target_modules_path = kwargs.get('target_modules_path', '') *** 0116: controller = OERuntimeTestContextExecutor.getControllerModule(target_type, target_modules_path) 0117: target = controller(logger, target_ip, server_ip, **kwargs) 0118: 0119: return target 0120: File: 'poky/meta/lib/oeqa/runtime/context.py', lineno: 128, function: getControllerModule 0124: # ImportError raised if a provided module can not be imported. 0125: @staticmethod 0126: def getControllerModule(target, target_modules_path): 0127: controllerslist = OERuntimeTestContextExecutor._getControllerModulenames(target_modules_path) *** 0128: controller = OERuntimeTestContextExecutor._loadControllerFromName(target, controllerslist) 0129: return controller 0130: 0131: # Return a list of all python modules in lib/oeqa/controllers for each 0132: # layer in bbpath File: 'poky/meta/lib/oeqa/runtime/context.py', lineno: 163, function: _loadControllerFromName 0159: # Raise ImportError if a provided module can not be imported 0160: @staticmethod 0161: def _loadControllerFromName(target, modulenames): 0162: for name in modulenames: *** 0163: obj = OERuntimeTestContextExecutor._loadControllerFromModule(target, name) 0164: if obj: 0165: return obj 0166: raise AttributeError("Unable to load {0} from available modules: {1}".format(target, str(modulenames))) 0167: File: 'poky/meta/lib/oeqa/runtime/context.py', lineno: 173, function: _loadControllerFromModule 0169: @staticmethod 0170: def _loadControllerFromModule(target, modulename): 0171: obj = None 0172: # import module, allowing it to raise import exception *** 0173: module = __import__(modulename, globals(), locals(), [target]) 0174: # look for target class in the module, catching any exceptions as it 0175: # is valid that a module may not have the target class. 0176: try: 0177: obj = getattr(module, target) Exception: ImportError: No module named 'oeqa.controllers.'
