How do you generate dynamic (parameterized) unit tests in python?
...ass TestSequence(unittest.TestCase):
@parameterized.expand([
["foo", "a", "a",],
["bar", "a", "b"],
["lee", "b", "b"],

def test_sequence(self, name, a, b):
self.assertEqual(a,b)
Which will generate the tests:

Best practices for exception management in Java or C# [closed]
...e the issues are
pretty easy to see there. Let's say I
create a method foo that declares it
throws exceptions A, B, and C. In
version two of foo, I want to add a
bunch of features, and now foo might
throw exception D. It is a breaking
change for me to add D to the throws
clause of th...

...oss this "need", it ultimately boils down to this construct:
public class Foo<T> {
private T t;
public Foo() {
this.t = new T(); // Help?
}
}
This does work in C# assuming that T has a default constructor. You can even get the runtime type by typeof(T) and get the con...
Getting values from query string in an url using AngularJS $location
...e so:
$location.search().user
If you wish not to use a key, value like ?foo=bar, I suggest using a hash #test_user_bLzgB ,
