Evaluate your unit test skills
You can install wrong through Python Package Index (PyPI):
pip install wrong
To evaluate your unit test skills, first write test functions for any of the modules in wrong. (We chose wrong.sort here) Then, import sort and run your test.
from wrong import sort
def test_sort_sorted():
a = [1, 2, 3, 4]
answer = [1, 2, 3, 4]
sort(a)
assert a == answer
def test_sort_unsorted():
a = [1, 4, 2, 3]
answer = [1, 2, 3, 4]
sort(a)
assert a == answer
If some of your unit tests fail, try testing with other implementations of sort with wrong.importer(module_name, function_id).
import wrong
sort = wrong.importer('sort', 0)
def test_sort_sorted():
a = [1, 2, 3, 4]
answer = [1, 2, 3, 4]
sort(a)
assert a == answer
def test_sort_unsorted():
a = [1, 4, 2, 3]
answer = [1, 2, 3, 4]
sort(a)
assert a == answer
sort has 1 correct implementation with id 0, and 4 incorrect implementations with ids 1, 2, 3, 4. If your tests pass for all correct implementations and fail for all incorrect implementations, your unit tests are working as intended!
