comparable_pattern

A comparable string / regex object for flexible string comparisons.

Useful for making unit tests less brittle without extensive mocking of things like timestamps and hashes which maybe change from one run to another.

Examples

>>> p = compile("foo")
>>> c = ComparablePattern(p)
>>> p == "foo"
False
>>> c == "foo"
True
>>> c == "bar"
False

>>> c = "foo" + ComparablePattern(compile("\d{3}"))
>>> c == "foo"
False
>>> c == "123"
False
>>> c == "foo123"
True

>>> c = ComparablePattern(compile("\d{3}")) + "bar"
>>> c == "bar"
False
>>> c == "123"
False
>>> c == "123bar"
True

>>> c = ComparablePattern(compile("\d{3}")) + ComparablePattern(compile("\w{3}"))
>>> c == "123"
False
>>> c == "abc"
False
>>> c == "123abc"
True
