How can I integrate snapshot testing into my CI pipeline?
Integrating snapshot testing into your CI pipeline involves a few key steps. First, ensure you have a testing framework that supports snapshot testing, like Jest. Then, add snapshot tests to your codebase.
What tools do I need to set this up?
You'll need a testing framework like Jest or Mocha, and a CI tool like GitHub Actions, Travis CI, or CircleCI.
Can you give me an example of a snapshot test?
Sure! In Jest, you can create a snapshot test like this: test('renders correctly', () => { const tree = renderer.create(<MyComponent />).toJSON(); expect(tree).toMatchSnapshot(); });
.
How do I ensure my snapshots are up to date?
You can update your snapshots by running the command jest --updateSnapshot
whenever you make changes to your components.
