About

---

Welcome to "let's explore pytest", which includes several pytest

examples. pytest is a testing framework that can be used to test Python code,

amongst other things, and lives at www.pytest.org. Python 3 is used exclusively

in this repository, though pytest can test Python 2 software.

These examples assume you are familiar with your shell or commandline, and are

able to set up your environment appropriately.

Environment

---

You will need (the versions we are using are in parentheses):

 - Python 3 (3.6.2)

 - pytest (3.2.1)

 - pytest-mock (1.6.0)

 - pytest-xdist (1.17.1)

The conda environment file `conda_environment.yml` is provided, which all

examples are designed to use.

Table of contents

---

Each example contains multiple `pytest` Python scripts.

 1. *Introductory examples*

    - Introduces pytest.

    - pytest reports failing tests, and has informative output.

    - pytest searches for tests automatically.

 2. *Fixtures, parameterisation, and parallelisation* (requires example 1)

    - Fixtures (decorated with `@pytest.fixture()`) are blocks of functionality

      that allow tests to be written in a modular way.

    - Fixtures are run when the test is run, and their output is passed to the

      test.

    - Fixtures can be used to parameterise tests, reducing code

      duplication. Each test is run individually of the others.

    - Parameterised tests run well in parallel (but be careful when testing

      software that itself runs in parallel!)

 3. *Testing software in isolation using mocking* (requires example 2)
