pystache.tests.test_context module

Unit tests of context.py.

class pystache.tests.test_context.ContextStackTestCase(methodName='runTest')

Bases: TestCase, AssertIsMixin, AssertStringMixin, AssertExceptionMixin

Test the ContextStack class.

test__repr()

test__str()

test_copy()

test_create__context()

Test passing a ContextStack instance.

test_create__dictionary()

Test passing a dictionary.

test_create__kwarg()

Test passing a keyword argument.

test_create__none()

Test passing None.

test_create__object()

Test passing an object.

test_create__precedence_keyword()

Test precedence of keyword arguments.

test_create__precedence_positional()

Test precedence of positional arguments.

test_dot_notation__autocall()

test_dot_notation__dict()

test_dot_notation__missing_attr_or_key()

test_dot_notation__missing_part_terminates_search()

Test that dotted name resolution terminates on a later part not found.

Check that if a later dotted name part is not found in the result from the former resolution, then name resolution terminates rather than starting the search over with the next element of the context stack. From the spec (interpolation section)–

5) If any name parts were retained in step 1, each should be resolved against a context stack containing only the result from the former resolution. If any part fails resolution, the result should be considered falsey, and should interpolate as the empty string.

This test case is equivalent to the test case in the following pull request:

test_get__key_missing()

Test getting a missing key.

test_get__key_present()

Test getting a single dot (“.”).

test_get__single_dot__missing()

Test getting a single dot (“.”) with an empty context stack.

test_init__many_elements()

Check that passing more than two items to __init__() raises no exception.

test_init__no_elements()

Check that passing nothing to __init__() raises no exception.

test_pop()

Test pop().

test_push()
