abstract
how to use pytest.
1.requirements
Jetson Xavier NX
ubuntu18.04
docker
python3.x
2.Install necessary modules
pip install pytest pytest-cov
3.Create files and directories
pytest directory : contains a set of test code
test_function.py : test code
function:target function
workspace ├── pytest/ │ ├── __init__.py │ └── test_function.py │ ├── __init__.py └── function.py
4.Write code in function.py and test_function.py
function.py
def inc(x): return x + 1
test_function.py
from .. import function # import function def test_answer(): assert function.inc(4) == 5
5.test
Execute the following command in the directory where function.py is stored
pytest
pass case
