Test, mock, intercept and modify Apollo Client's operations — in both browser and unit tests!
Read the Medium article about Laika: Mock GraphQL Subscriptions with Laika — the only Apollo Client mocking tool you’ll need
Features
-
mock responses in either unit tests or browser tests (think Puppeteer or Cypress)
- simulate error state
- simulate loading state
- simulate subscriptions (pushing data to the client at any given point)
- it can work in production code without affecting the size of the bundle (laika is lazily loaded)
- captures the variables that were called for a given operation for assertions
- log all the data passing through from the network (or whatever Links are after this one)
- record your user story
- generate fixtures and working mock code for use in your tests
- modify backend responses before they reach your components (e.g. to fuzz-test unexpected behavior)
Usage
Alternatives
-
MockedProvider- the official Apollo mocking tool designed for unit tests; offers no subscription mocking or recording functionality
