unit testing - Mock patch decorators python -


hi mock decorator since don't want calling/executing function. can't seem find solution below code

# decorator located in project # located in custom.mydecorators.decorator_file.custom_decorator base = declarative_base()   def custom_decorator(func):   @wraps(func)   def wrapper(*args, **kwargs):     print("this message still printed when try patch function")     try:         #code here         my_var = coolclass()         retval = func(*args, **kwargs)     except exception e:         #rollback code here         raise e      return retval   return wrapper

now i'm trying patch using code

patch('custom.mydecorators.decorator_file.custom_decorator', lambda x: x).start()   class testmockdecoratorscallingclass(unittest.testcase): def test_should_return_success_if_decorators_are_mocked(self):     # code here

my decorators work in non unittest file. if mock decorator fails saying local variable 'my_var' referenced before assignment

note: my_var inside decorator i'm trying mock/patch print message still executed when try patch it

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
