Running all python unittests from different modules as a suite having parameterized class constructor - python-unittest

I am working on a design pattern to make my python unittest as a POM, so far I have written my page classes in modules HomePageObject.py,FilterPageObject.py, my base class (for common stuff)TestBase in BaseTest.py, my testcase modules are TestCase1.py and TestCase2.py and one runner module runner.py.
In runner class i am using loader.getTestCaseNames to get all the tests from a testcase class of a module. In both the testcase modules the name of the test class is same 'Test' and also the method name is same 'testName'
Since the names are confilicting while importing it in runner, only one test is getting executed. I want python to scan all the modules that i specify for tests in them and run those even the name of classes are same.
I got to know that nose might be helpful in this, but not sure how i can implement it here. Any advice ?
BaseTest.py

super(TestBase,self).__init__(testName)
def setUp(self):
if self.browser == "firefox":
TestBase.driver = webdriver.Firefox()
elif self.browser == "chrome":
options = ChromeOptions()
options.add_argument("--start-maximized")
TestBase.driver = webdriver.Chrome(chrome_options=options)
self.url = "https://www.airbnb.co.in/"
self.driver = TestBase.getdriver()
TestBase.driver.implicitly_wait(10)

I did this by searching for all the modules of test classes with a pattern and then used __import__(modulename) and called its Test class with desired parameters,

suite = unittest.TestSuite()
test_file_strings = glob.glob('Test*.py')
module_strings = [str[0:len(str)-3] for str in test_file_strings]

mod = __import__(module)
test_names =loader.getTestCaseNames(mod.Test)
for test in test_names:
suite.addTest(mod.Test(test,"chrome"))
runner = unittest.TextTestRunner()
result = runner.run(suite)
This worked but still looking for some organized solutions.

How to load Hydra parameters from previous jobs (without having to use argparse and the compose API)?

I'm using Hydra for training machine learning models. It's great for doing complex commands like python train.py data=MNIST batch_size=64 loss=l2. However, if I want to then run the trained model with the same parameters, I have to do something like python reconstruct.py --config_file path_to_previous_job/.hydra/config.yaml. I then use argparse to load in the previous yaml and use the compose API to initialize the Hydra environment. The path to the trained model is inferred from the path to Hydra's .yaml file. If I want to modify one of the parameters, I have to add additional argparse parameters and run something like python reconstruct.py --config_file path_to_previous_job/.hydra/config.yaml --batch_size 128. The code then manually overrides any Hydra parameters with those that were specified on the command line.
What's the right way of doing this?
My current code looks something like the following:
train.py:
import hydra
#hydra.main(config_name="config", config_path="conf")
def main(cfg):
# [training code using cfg.data, cfg.batch_size, cfg.loss etc.]
# [code outputs model checkpoint to job folder generated by Hydra]
main()
reconstruct.py:
import argparse
import os
from hydra.experimental import initialize, compose
if __name__ == '__main__':
parser = argparse.ArgumentParser()
parser.add_argument('hydra_config')
parser.add_argument('--batch_size', type=int)
# [other flags and parameters I may need to override]
args = parser.parse_args()
# Create the Hydra environment.
initialize()
cfg = compose(config_name=args.hydra_config)
# Since checkpoints are stored next to the .hydra, we manually generate the path.
checkpoint_dir = os.path.dirname(os.path.dirname(args.hydra_config))
# Manually override any parameters which can be changed on the command line.
batch_size = args.batch_size if args.batch_size else cfg.data.batch_size
# [code which uses checkpoint_dir to load the model]
# [code which uses both batch_size and params in cfg to set up the data etc.]
This is my first time posting, so let me know if I should clarify anything.
If you want to load the previous config as is and not change it, use OmegaConf.load(file_path).
If you want to re-compose the config (and it sounds like you do, because you added that you want override things), I recommend that you use the Compose API and pass in parameters from the overrides file in the job output directory (next to the stored config.yaml), but concatenate the current run parameters.
This script seems to be doing the job:
import os
from dataclasses import dataclass
from os.path import join
from typing import Optional
from omegaconf import OmegaConf
import hydra
from hydra import compose
from hydra.core.config_store import ConfigStore
from hydra.core.hydra_config import HydraConfig
from hydra.utils import to_absolute_path
# You can also use a yaml config file instead of this Structured Config
#dataclass
class Config:
load_checkpoint: Optional[str] = None
batch_size: int = 16
loss: str = "l2"
cs = ConfigStore.instance()
cs.store(name="config", node=Config)
#hydra.main(config_path=".", config_name="config")
def my_app(cfg: Config) -> None:
if cfg.load_checkpoint is not None:
output_dir = to_absolute_path(cfg.load_checkpoint)
original_overrides = OmegaConf.load(join(output_dir, ".hydra/overrides.yaml"))
current_overrides = HydraConfig.get().overrides.task
hydra_config = OmegaConf.load(join(output_dir, ".hydra/hydra.yaml"))
# getting the config name from the previous job.
config_name = hydra_config.hydra.job.config_name
# concatenating the original overrides with the current overrides
overrides = original_overrides + current_overrides
# compose a new config from scratch
cfg = compose(config_name, overrides=overrides)
# train
print("Running in ", os.getcwd())
print(OmegaConf.to_yaml(cfg))

mocked function is called but fails assert_called test

I have a test like:
import somemodule
import somemodule2
class SomeTestCase(unittest.TestCase):
def setUp(self):
super().setUp()
self.ft_mock = mock.MagicMock(spec=somemodule.SomeClass,
name='mock_it')
def tearDown(self) -> None:
self.ft_mock.reset_mock(return_value=True, side_effect=True)
#mock.patch('somemodule2.someFunk2',
name = 'mock_2',
spec=True,
side_effect='some val')
def testSomething(self, mock_rr):
m = self.ft_mock
m.addMemberSomething()
self.assertEqual(len(m.addMember.call_args_list), 1)
m.addSomethingElse.return_value = 'RETURN IT'
m.addSomethingElse()
m.addSomethingElse.assert_called_once()
res = somemodule.FooClass.foo()
mock_rr.assert_called()
Here somemodule.FooClass.foo() internally calls someFunk2 from somemodule2 which has been mocked as mock_rr
In the test debug it does call it as i print out a line from someFunk2 but testing it when mock_rr.assert_called() is called, it throws:
AssertionError: Expected 'mock_2' to have been called.
I've tried several ways using patch and patch.object
The issue was that somemodule also imported someFunk2 from somemodule2.
So when patching/mocking, the patched object was from somemodule2 while the object that Needed to be patched was somemodule.someFunk2

the testcase did not run when run as test suite with unittest framework

this is my testrun,there are cases in the imported testclass
from apa_login import Apa_login
from processmap import Show_processmap
import unittest,HTMLTestRunner,apa_login,processmap
def suite(self):
suite = unittest.TestSuite()
suite = unittest.TestLoader().loadTestsFromTestCase(Apa_login)
suite = unittest.TestLoader().loadTestsFromTestCase(Show_processmap)
return suite
if __name__ == '__main__':
runner = unittest.TextTestRunner()
runner.run(suite)
print suite
then it gives me this result??
$ python testrun.py
Ran 0 tests in 0.001s
OK
It should not be 0 tests,right?
You need to pass the TestSuite instance to runner.run() by invoking the suite() function. You're currently passing the suite function itself.
runner.run(suite()) # Pass the TestSuite by invoking suite()
Also note that you should probably remove the self argument from suite() if that function is not part of a class.

How to get sys.exc_traceback form IPython shell.run_code?

My app interfaces with the IPython Qt shell with code something like this:
from IPython.core.interactiveshell import ExecutionResult
shell = self.kernelApp.shell # ZMQInteractiveShell
code = compile(script, file_name, 'exec')
result = ExecutionResult()
shell.run_code(code, result=result)
if result:
self.show_result(result)
The problem is: how can show_result show the traceback resulting from exceptions in code?
Neither the error_before_exec nor the error_in_exec ivars of ExecutionResult seem to give references to the traceback. Similarly, neither sys nor shell.user_ns.namespace.get('sys') have sys.exc_traceback attributes.
Any ideas? Thanks!
Edward
IPython/core/interactiveshell.py contains InteractiveShell._showtraceback:
def _showtraceback(self, etype, evalue, stb):
"""Actually show a traceback. Subclasses may override..."""
print(self.InteractiveTB.stb2text(stb), file=io.stdout)
The solution is to monkey-patch IS._showtraceback so that it writes to sys.stdout (the Qt console):
from __future__ import print_function
...
shell = self.kernelApp.shell # ZMQInteractiveShell
code = compile(script, file_name, 'exec')
def show_traceback(etype, evalue, stb, shell=shell):
print(shell.InteractiveTB.stb2text(stb), file=sys.stderr)
sys.stderr.flush() # <==== Oh, so important
old_show = getattr(shell, '_showtraceback', None)
shell._showtraceback = show_traceback
shell.run_code(code)
if old_show: shell._showtraceback = old_show
Note: there is no need to pass an ExecutionResult object to shell.run_code().

Create a portal_user_catalog and have it used (Plone)

I'm creating a fork of my Plone site (which has not been forked for a long time). This site has a special catalog object for user profiles (a special Archetypes-based object type) which is called portal_user_catalog:
$ bin/instance debug
>>> portal = app.Plone
>>> print [d for d in portal.objectMap() if d['meta_type'] == 'Plone Catalog Tool']
[{'meta_type': 'Plone Catalog Tool', 'id': 'portal_catalog'},
{'meta_type': 'Plone Catalog Tool', 'id': 'portal_user_catalog'}]
This looks reasonable because the user profiles don't have most of the indexes of the "normal" objects, but have a small set of own indexes.
Since I found no way how to create this object from scratch, I exported it from the old site (as portal_user_catalog.zexp) and imported it in the new site. This seemed to work, but I can't add objects to the imported catalog, not even by explicitly calling the catalog_object method. Instead, the user profiles are added to the standard portal_catalog.
Now I found a module in my product which seems to serve the purpose (Products/myproduct/exportimport/catalog.py):
"""Catalog tool setup handlers.
$Id: catalog.py 77004 2007-06-24 08:57:54Z yuppie $
"""
from Products.GenericSetup.utils import exportObjects
from Products.GenericSetup.utils import importObjects
from Products.CMFCore.utils import getToolByName
from zope.component import queryMultiAdapter
from Products.GenericSetup.interfaces import IBody
def importCatalogTool(context):
"""Import catalog tool.
"""
site = context.getSite()
obj = getToolByName(site, 'portal_user_catalog')
parent_path=''
if obj and not obj():
importer = queryMultiAdapter((obj, context), IBody)
path = '%s%s' % (parent_path, obj.getId().replace(' ', '_'))
__traceback_info__ = path
print [importer]
if importer:
print importer.name
if importer.name:
path = '%s%s' % (parent_path, 'usercatalog')
print path
filename = '%s%s' % (path, importer.suffix)
print filename
body = context.readDataFile(filename)
if body is not None:
importer.filename = filename # for error reporting
importer.body = body
if getattr(obj, 'objectValues', False):
for sub in obj.objectValues():
importObjects(sub, path+'/', context)
def exportCatalogTool(context):
"""Export catalog tool.
"""
site = context.getSite()
obj = getToolByName(site, 'portal_user_catalog', None)
if tool is None:
logger = context.getLogger('catalog')
logger.info('Nothing to export.')
return
parent_path=''
exporter = queryMultiAdapter((obj, context), IBody)
path = '%s%s' % (parent_path, obj.getId().replace(' ', '_'))
if exporter:
if exporter.name:
path = '%s%s' % (parent_path, 'usercatalog')
filename = '%s%s' % (path, exporter.suffix)
body = exporter.body
if body is not None:
context.writeDataFile(filename, body, exporter.mime_type)
if getattr(obj, 'objectValues', False):
for sub in obj.objectValues():
exportObjects(sub, path+'/', context)
I tried to use it, but I have no idea how it is supposed to be done;
I can't call it TTW (should I try to publish the methods?!).
I tried it in a debug session:
$ bin/instance debug
>>> portal = app.Plone
>>> from Products.myproduct.exportimport.catalog import exportCatalogTool
>>> exportCatalogTool(portal)
Traceback (most recent call last):
File "<console>", line 1, in <module>
File ".../Products/myproduct/exportimport/catalog.py", line 58, in exportCatalogTool
site = context.getSite()
AttributeError: getSite
So, if this is the way to go, it looks like I need a "real" context.
Update: To get this context, I tried an External Method:
# -*- coding: utf-8 -*-
from Products.myproduct.exportimport.catalog import exportCatalogTool
from pdb import set_trace
def p(dt, dd):
print '%-16s%s' % (dt+':', dd)
def main(self):
"""
Export the portal_user_catalog
"""
g = globals()
print '#' * 79
for a in ('__package__', '__module__'):
if a in g:
p(a, g[a])
p('self', self)
set_trace()
exportCatalogTool(self)
However, wenn I called it, I got the same <PloneSite at /Plone> object as the argument to the main function, which didn't have the getSite attribute. Perhaps my site doesn't call such External Methods correctly?
Or would I need to mention this module somehow in my configure.zcml, but how? I searched my directory tree (especially below Products/myproduct/profiles) for exportimport, the module name, and several other strings, but I couldn't find anything; perhaps there has been an integration once but was broken ...
So how do I make this portal_user_catalog work?
Thank you!
Update: Another debug session suggests the source of the problem to be some transaction matter:
>>> portal = app.Plone
>>> puc = portal.portal_user_catalog
>>> puc._catalog()
[]
>>> profiles_folder = portal.some_folder_with_profiles
>>> for o in profiles_folder.objectValues():
... puc.catalog_object(o)
...
>>> puc._catalog()
[<Products.ZCatalog.Catalog.mybrains object at 0x69ff8d8>, ...]
This population of the portal_user_catalog doesn't persist; after termination of the debug session and starting fg, the brains are gone.
It looks like the problem was indeed related with transactions.
I had
import transaction
...
class Browser(BrowserView):
...
def processNewUser(self):
....
transaction.commit()
before, but apparently this was not good enough (and/or perhaps not done correctly).
Now I start the transaction explicitly with transaction.begin(), save intermediate results with transaction.savepoint(), abort the transaction explicitly with transaction.abort() in case of errors (try / except), and have exactly one transaction.commit() at the end, in the case of success. Everything seems to work.
Of course, Plone still doesn't take this non-standard catalog into account; when I "clear and rebuild" it, it is empty afterwards. But for my application it works well enough.
