Hi. My project has both unit and property tests. Unit tests are using a mocking library but I don’t need my property tests to run with the mocks, so I decided to split my test env into two: test
and property_test
using test.exs
and property_test.exs
config files respectively. Finally, I’m running these tests using the commands:
$ MIX_ENV=property_test mix test test/property/
$ MIX_ENV=test mix test test/unit
Now, I would like to instead create custom commands to simplify things using Mix’s aliases but I don’t know how to achieve it. Like how would that look like ? I don’t know how to tell Mix which env it should execute each alias with. This is what I have so far in my mix.exs
def cli do
[preferred_envs: ["test.unit": :test, "test.property": :property_test]]
end
defp aliases() do
[
"test.property": ["test test/property/"],
"test.unit": ["test test/unit"]
]
end
But I’m still getting this error
** (Mix) “mix test” is running in the “property_test” environment. If you are running tests from within another command, you can either:
set MIX_ENV explicitly:
MIX_ENV=test mix test.another
set the :preferred_envs for “def cli” in your mix.exs:
def cli do
[preferred_envs: [“test.another”: :test]]
end
