Test code blocks in your READMEs.

This is pytest-codeblocks, a pytest plugin for testing code blocks from README files. It supports Python and shell code.

Install with

pip install pytest-codeblocks

and run pytest with

pytest --codeblocks

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

Skipping code blocks

Prefix your code block with a pytest-codeblocks:skip comment to skip

Lorem ipsum

<!--pytest-codeblocks:skip-->

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

dolor sit amet.

Conditionally skipping code blocks works with skipif, e.g.,

<!--pytest-codeblocks:skipif(sys.version_info <= (3, 7))-->

Merging code blocks

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

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:

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:

This

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

gives

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

```
4
```

Expected errors

Some code blocks are expected to give errors. You can verify this with

The following gives an error:

<!--pytest-codeblocks:expect-error-->

```python
1 / 0
```

The keyword expect-exception is also possible.
