Brownie uses the attest framework for testing in combination with tox. This allows us to easily create unit tests, to test our documentation and to run all tests using various configurations defined through their test environments.
Usually you just want to run all tests, in order to do that simply execute:
$ make test
Sometimes you may want to run tests only in a specific test environment, in order to do that you need to use tox directly:
$ tox -e <testenv>
If you are developing a specific feature you rarely care about the tests for all the modules you are currently not working on. In this case you can select the module you want to test by calling tox and passing the name of the module:
$ tox -- <module>
<module> can be any module in brownie.tests which has a attest.Tests collection under the attribute tests. If you want to run the tests in multiple modules you can do that by passing each name as an argument to tox.
At the moment the following test environments are available:
