# Unit tests
|
||||
|
||||
Unit tests test some smaller individual parts of code (mainly functions and classes) and are run by micropython directly.
|
||||
|
||||
## 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`.
