"TDD in Python with pytest" workshop
This is a Python package used for the "TDD in Python with pytest" workshop.
The master branch contains an empty project with no tests. The develop branch points to the full project, and each commit is a step in the workshop. The commit messages are prefixed with either "T" or "C", to show if that commit adds "Tests" or "Code".
The description of the project is the following:
The goal is to write a class Calc that performs calculations: addition, subtraction,
multiplication, and division. Addition and multiplication shall accept multiple arguments.
Division shall return a float and division by zero shall return the string "inf".
Multiplication by zero must raise a ValueError exception. The class will also provide
a function to compute the average of an iterable. This function gets two optional upper
and lower thresholds to remove outliers.(some of the requirements are silly but they help understanding some TDD concepts)
Instructions
- Clone the repository
- Create a virtual environment:
python3 -m venv <venvname>(where is the name of the environment, e.g.myvenv) - Activate it:
source <venvname>/bin/activate - Install requirements:
pip install -r requirements/dev.txt - Edit the
pytest.inifile and add the virtualenvironment to thenorecursedirsoption
[pytest]
minversion = 2.0
norecursedirs = .git .tox requirements* <venvname>
python_files = test*.py- Run
pytest -svvto check that everything has been correctly installed. You should get a result like
