Mutation testing for Elixir
Muzak
Mutation testing for Elixir!
Getting Started
To get started with mutation testing, first add muzak
as a dependency in your mix.exs
file and
set the preferred_cli_env
for muzak
to test
:
defmodule MyApp.Mixfile do
def project do
[
# ...
preferred_cli_env: [muzak: :test]
]
end
# ...
defp deps do
[
# ...
{:muzak, "~> 1.1", only: :test}
]
end
end
You're now ready to get started!
$ mix deps.get
$ mix muzak
Muzak will then randomly generate up to 1000 mutations in your application and run your test suite against each of them. If your application contains more than 1000 possible mutations, then you may see different results for subsequent runs.
