Running a python script with nose.run(...) from outside of the script's directory results in AttributeError: 'module' object has no attribute 'tests' -

-

i have python application few sub directories. each subdirectory has own tests.py file.

i use nose run of unittests across of these files in 1 shot, creating script run_unit_tests.py calls nose.run(...).

if inside of directory containing run_unit_tests.py, works fine. however, if anywhere else on file system, fails attributeerror: 'module' object has no attribute 'tests'.

here similar directory structure:

myapp/     foo/         __init__.py         tests.py         bar/             __init__.py             tests.py     run_unit_tests.py

in run_unit_tests.py:

class myplugin(plugin):     ...  if __name__ == '__main__':     nose.run(argv=['', 'foo.tests', '--with-my-plugin'])     nose.run(argv=['', 'foo.bar.tests', '--with-my-plugin'])

if run run_unit_tests.py while inside top myapp directory, works fine.

however, if run script while in other folder on file system, fails with:

====================================================================== error: failure: attributeerror ('module' object has no attribute 'tests') ---------------------------------------------------------------------- traceback (most recent call last):   file "/apps/python/lib/python2.7/site-packages/nose/loader.py", line 407, in loadtestsfromname     module = resolve_name(addr.module)   file "/apps/python/lib/python2.7/site-packages/nose/util.py", line 322, in resolve_name     obj = getattr(obj, part) attributeerror: 'module' object has no attribute 'tests'

in fact, if add following run_unit_tests.py, works fine:

import os os.chdir('/path/to/myapp')

what can change inside of nose script such can run script outside of directory?

actually, want careful here. because, reason why happening because imports in test respect to: /path/to/myapp.

so, when run tests working directory, unit test files importing respect directory being project source. if change directories , run location, becomes root, , imports surely fail.

this bring different opinions, make sure sources referenced same project root. if here: 

myapp/     foo/         __init__.py         tests.py         bar/             __init__.py             tests.py     run_unit_tests.py

i run within myapp

furthemore, consider creating tests directory , putting tests in directory, making imports easier manage , better segregating code. however, opinion, please don't feel necessity. whatever works you, go it.

hope helps.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
