Contract Testing Between Micro Frontends
Learn how contract testing verifies that the interfaces micro frontends expose and consume stay compatible, catching breaking changes before deployment.
The Integration Gap
Unit tests check one MFE in isolation; E2E tests are slow and brittle. Contract testing fills the gap by verifying the agreements between MFEs without running everything together.
What Is a Contract?
A contract is the shape of an interaction between two parties — the exposed module signature, an event payload, or a shared state shape. Both sides must agree on it.
