API Contract Test Pack

Tests that fail the build when an endpoint changes shape, so back-end releases stop breaking your clients.

9 working days

Revisions

Ownership

Yours from day one

Overview

What this engagement is

Front-end and mobile teams break not because an API went down, but because a field quietly became nullable. Contract tests catch that. We build a suite that validates every response against its schema, checks status codes and error formats, and asserts the authorisation rules that matter, such as one customer being unable to fetch another customer's record. The suite runs on every pull request, so a breaking change is a failing build rather than a support ticket from a partner three weeks later.

Deliverables

What lands in your repositories

7 items
  • Contract tests for up to 40 endpoints validated against the schema
  • Status code, error format and header assertions per endpoint
  • Authorisation tests confirming role boundaries and object-level access
  • Negative tests covering malformed input and missing fields
  • CI integration with clear reporting on which contract broke
  • Schema snapshots so unintended changes are visible in a diff
  • Documentation on adding tests for new endpoints

Outcomes

What changes once it ships

Breaking changes fail in CI instead of on a customer device

Refactoring becomes safe because the contract is enforced

Shipped mobile clients stop breaking on server releases

Process

How the 4 stages run

  1. 01

    Baseline

    endpoints catalogued and current response shapes captured

  2. 02

    Specify

    expected contracts confirmed with your engineers, gaps flagged

  3. 03

    Build

    tests written per endpoint, including negative and authorisation cases

  4. 04

    Integrate

    suite added to CI and demonstrated with a deliberate break

Booked most often by

  • Teams with a mobile app that cannot be updated as fast as the server
  • Products with external partners consuming the API
  • Backends where refactoring is avoided out of fear

What we need from you

  • API access with credentials for each role
  • An OpenAPI specification if you have one, though we can work without
  • An engineer to confirm intended behaviour where it is ambiguous

These are collected in the technical brief that opens in your dashboard the moment payment clears. The clock starts when they arrive, not before.

Answers

Questions this engagement raises

No. Unit tests check internal logic. These check the promise your API makes to everyone consuming it.

We capture current behaviour and confirm what is intentional. That process usually finds a few surprises.

Yes, through schema and query-level assertions. Same approach, same price.

This is engineering work, not a physical product — nothing ships and there is no stock to run out of. Delivery is to the working days stated above, into systems you control, and the refund terms set out what happens if we miss the date.
