# Unit tests Unit tests test some smaller individual parts of code (mainly functions and classes) and are run by micropython directly. ## How to run them Run all tests: ```sh make test ``` Run a specific test file: ```sh make test TESTOPTS=test_apps.bitcoin.signtx.py ``` __WARNING__: unittests cannot run with frozen emulator, use `make build_unix` to create non-frozen emulator. ## Usage Please use the unittest.TestCase class: ```python from common import * class TestSomething(unittest.TestCase): test_something(self): self.assertTrue(True) ``` Usage of `assert` is discouraged because it is not evaluated in production code (when `PYOPT=1`). Use `self.assertXY` instead, see `unittest.py`.
