-
mock_openLine Iteration
Example Uses
Below are some example uses for some of the features.
Temporary Files
def test_using_temp_file(self):
with TestFile(TEST_FILE, TEST_DATA) as tf:
# File TEST_FILE now exists with TEST_DATA inside.
tf.append(MORE_TEST_DATA)
# File TEST_FILE now has TEST_DATA with MORE_TEST_DATA appended.
# File TEST_FILE no longer exists.RunTimer
A RunTimer is provied to help compare run times of code.
with RunTimer() as t:
t0 = t.split()
t1 = t.split()
t2 = t.overall()mock_open Line Iteration
When mocking a file using mock_open, "code-under-test" using line iteration (as in the example below) will not work as expected. (do_something will not be called.)
def my_function(fn):
with open(fn, 'r') as f:
for l in f:
do_something(l)To enable line iteration you can use add_line_iter_to_mock_open.
@patch('builtins.open', new_callable=mock_open, read_data='line 0\nline 1\n')
def test_function(self, open_mock):
add_line_iter_to_mock_open(open_mock)
# Line iteration over the mock_open read_data will now work.Additional Asserts
To use the additional asserts, add the mixin to your TestCase class.
class MixedTestCase(TestCase, AdditionalAssertsMixin):
def test_a_test:
self.assertIsEmpty([])
self.assertIsNotEmpty(('hello',))The new asserts are:
| Method | Checks that ... |
|---|---|
assertIsEmpty(c) |
len(c) == 0 |
assertIsNotEmpty(c) |
len(c) > 0 |
