npm install jest-pdf-snapshot =========================== CAUTION ===========================

``javascript
const { toMatchPdfSnapshot } = require('jest-pdf-snapshot');
expect.extend({ toMatchPdfSnapshot });
test('Snapshot matches', () => {
const pdf = fs.readFileSync('../resources/test1.pdf');
expect(pdf).toMatchPdfSnapshot();
});
`
Would give you following files:
``
├── resources/test1.pdf
└── __tests__
├── pdf_snapshots
│ ├── __diff_output__
| | └── pdf-snapshot-test-js-snapshot-is-different-1-diff.pdf
| | (in case snapshot doesn't match)
│ └── pdf-snapshot-test-js-snapshot-matches-1.pdf
└── pdf-snapshot.test.js
If you want to play with working example, see our mock project in __tests__/mock_project, which we use for integration tests.
After you've set up diff-pdf, you can install jest-pdf-snapshot just with:
`shell``
npm install --save-dev jest-pdf-snapshot
