¶
Implementation of simple resource sharing cache for unit tests
-
class
plainbox.testing_utils.resource.
Dict
[source]¶ Bases:
dict
A dict() that can be weakly referenced
See: http://docs.python.org/3/library/weakref.html
-
clear
() → None. Remove all items from D.¶
-
copy
() → a shallow copy of D¶
-
fromkeys
()¶ Returns a new dict with keys from iterable and values equal to value.
-
get
(k[, d]) → D[k] if k in D, else d. d defaults to None.¶
-
items
() → a set-like object providing a view on D's items¶
-
keys
() → a set-like object providing a view on D's keys¶
-
pop
(k[, d]) → v, remove specified key and return the corresponding value.¶ If key is not found, d is returned if given, otherwise KeyError is raised
-
popitem
() → (k, v), remove and return some (key, value) pair as a¶ 2-tuple; but raise KeyError if D is empty.
-
setdefault
(k[, d]) → D.get(k,d), also set D[k]=d if k not in D¶
-
update
([E, ]**F) → None. Update D from dict/iterable E and F.¶ If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
-
values
() → an object providing a view on D's values¶

class

List
[source]¶ Bases:
list
A list() that can be weakly referenced
See: http://docs.python.org/3/library/weakref.html
-
append
(object) → None -- append object to end¶
-
clear
() → None -- remove all items from L¶
-
copy
() → list -- a shallow copy of L¶
-
count
(value) → integer -- return number of occurrences of value¶
-
extend
(iterable) → None -- extend list by appending elements from the iterable¶
-
index
(value[, start[, stop]]) → integer -- return first index of value.¶ Raises ValueError if the value is not present.
-
insert
()¶ L.insert(index, object) – insert object before index
-
pop
([index]) → item -- remove and return item at index (default last).¶ Raises IndexError if list is empty or index is out of range.
-
remove
(value) → None -- remove first occurrence of value.¶ Raises ValueError if the value is not present.
-
reverse
()¶ L.reverse() – reverse IN PLACE
-
sort
(key=None, reverse=False) → None -- stable sort *IN PLACE*¶

ResourceCache
(weak=True)[source]¶ Bases:
object
Cache for expensive operations.
If your test needs to compute something (slowly) and reuse it in various different test_ methods then this will save time.
