I've got a class, in the constructor it loads a CSV file from disc. I'd
like only 1 instance of the class to be instantiated. However, when
running
multiple unit tests, multiple instances of the class are created. What's
the best way for me to avoid this? It takes about a few seconds to load
the
CSV file.
Use a factory function:
_instance = None
def createFoo(parameters):
if _instance is None:
_instance = Foo(parameters)
return _instance
and replace all occurrences of Foo(parameters) with createFoo(parameters).
For new-style classes, you may override the __new__ method instead.
Perhaps I didn't understand your problem correctly because this is
unrelated to unit testing...
