This is pytest-codeblocks, a [pytest](https://pytest.org/) plugin for testing code
blocks from README files. It supports Python and shell code.

Install with

```sh
pip install pytest-codeblocks
```

and run pytest with

```sh
pytest --codeblocks
```

```sh

pytest-codeblocks will only pick up code blocks with `python` and `sh`/`bash`/`zsh`
syntax highlighting.

#### Marking code blocks

It is possible to use `pytest.mark` for marking code blocks. For example,
to skip a code block use `pytest.mark.skip` or `pytest.mark.skipif`:

````markdown
Lorem ipsum

<!--pytest.mark.skip-->

```python
foo + bar  # not working
```

dolor sit amet.
````

```markdown
<!--pytest.mark.skipif(sys.version_info <= (3, 7), reason="Need at least Python 3.8")-->
```

You can skip code blocks on import errors with

```markdown
<!--pytest-codeblocks:importorskip(sympy)-->
```

Skip the entire file by putting

```markdown
<!--pytest-codeblocks:skipfile-->
```

in the first line.

For expected errors, use `pytest.mark.xfail`:

````markdown
The following gives an error:

<!--pytest.mark.xfail-->

```python
1 / 0
```
````

#### Merging code blocks

Broken-up code blocks can be merged into one with the `pytest-codeblocks:cont` prefix

````markdown
Lorem ipsum

```python
a = 1
```

dolor sit amet

<!--pytest-codeblocks:cont-->

```python
# this would otherwise fail since `a` is not defined
a + 1
```
````

If you'd like to prepend code that you don't want to show, you can just comment it out;
pytest-codeblocks will pick it up anyway:

````markdown
Lorem ipsum

<!--
```python
a = 1
```
-->

dolor sit amet

<!--pytest-codeblocks:cont-->

```python
# this would otherwise fail since `a` is not defined
a + 1
```
````

#### Expected output

You can also define the expected output of a code block:

````markdown
This

```sh
print(1 + 3)
```

gives

<!--pytest-codeblocks:expected-output-->

```
4
```
````

(Conditionally) Skipping the output verfication works by prepending the first
block with `skip`/`skipif` (see [above](#skipping-code-blocks)).
