[![NPM version](https://img.shields.io/npm/v/markdown-it-testgen.svg?style=flat)](https://www.npmjs.org/package/markdown-it-testgen)


> This package parses fixtures in commonmark spec format and generates tests for
[markdown-it](https://github.com/markdown-it/markdown-it) parser and
[plugins](https://www.npmjs.org/browse/keyword/markdown-it-plugin).


```bash
npm install markdown-it-testgen
```


## Fixture format

Each fixture can have optional metadata in yaml format:

```yaml
---
desc: Batch description # file name used if not exists.
skip: true              # mark batch as pending
---
```

Then tests should follow in this format:

```
optional header
.
source
data
.
parsed
data
.


header2
.
src
.
result
.
```

If header missed - line number will be used instead.


## API
