View Source mix mneme.watch (Mneme v0.9.0-alpha.1)
Runs the tests for a project when source files change.
This task is similar to mix test.watch
,
but updated to work with Mneme:
- interrupts Mneme prompts, saving already-accepted changes
- doesn't re-trigger when test files are updated by Mneme
Setup
To ensure mix mneme.watch
runs in the test environment, add a
:preferred_cli_env
entry in mix.exs
:
def project do
[
...
preferred_cli_env: [
"mneme.watch": :test
],
...
]
end
Command line options
This task runs mix test
under the hood and passes all CLI arguments
to it directly. For instance:
# only run tests tagged with `some_tag: true`
$ mix mneme.watch --only some_tag
# only run tests from one file
$ mix mneme.watch test/my_app/my_test.exs
See the mix test
documentation for more information.
