Ersatz is a library for defining mocks in Elixir.
Contributions welcome :-)
Ersatz in a fork of Mox and follows mosts of principles outlined in "Mocks and explicit contracts".
- Mocks are generated based on behaviours during configuration and injected using env variables.
- Add the mock behaviour by specifying functions to be used during tests with
Ersatz.set_mock_implementation/3. - Test your code's actions on the mock dependency using
Ersatz.get_mock_calls/1or the Espec custom matchers.
See the documentation for more information.
Add ersatz to your list of dependencies in mix.exs:
def deps do
[
{:ersatz, "~> 0.2", only: :test}
]
end- clarify documentation
- function to clear all previous calls
- add custom assertions for ExUnit
- function to configure only a return value instead of a complete function
- Test concurrency support. (should be ok, but... )
- add configuration for initializing mocks before start of application under test
Ersatz is a fork of Plataformatec Mox library.
