charms.harness_extensions.v0.declarative_tester_charm

This is a library providing a utility for unittesting code that's meant to be used in charms.

So not charm code per se, but e.g. library code, extensions, etc...

Basic usage:

from charms.harness_extensions.v0.charm_tester import harness_factory def test_lib(): harness = harness_factory() harness.begin() charm = harness.charm

@charm.run
def _initialize(self):
    self.lib = CharmLib(self)

@charm.listener(charm.on.my_lib_event)
def _on_my_lib_event(self, event):
    assert event.foo == 'bar'

assert not _on_my_lib_event.called
harness.do_things_to_trigger_lib_event()
assert isinstance(_on_my_lib_event.called, MyExpectedEventType)
