E2E and Integration Testing

E2E and Integration Testing

We design and implement end-to-end and integration tests that validate real user flows and system behaviour. These tests give you confidence that the system works as a whole—or that key integrations and APIs behave as expected—before each release.

What We Cover

• Scope — Critical paths, APIs, and contracts: what to cover first and how to keep tests maintainable so they do not become a bottleneck.
• Environments and data — Test environments, fixtures, and data setup so tests run reliably, stay fast, and do not depend on production data.
• Tooling — Playwright, Cypress, or other E2E and API testing tools aligned with your stack and team skills.
• Maintainability — Structure and patterns (e.g. page objects, shared helpers, clear assertions) so tests stay useful as the product evolves and do not block delivery.

Critical Paths and User Flows

We identify the flows that matter most to your users and your business—sign-up, checkout, core workflows—and prioritise E2E coverage for those. We avoid testing every possible path; instead we focus on the journeys that would cause the most damage if they broke and that are stable enough to justify the cost of E2E maintenance.

API and Contract Tests

Integration tests for APIs and services help you catch breaking changes early. We can add tests that call your APIs with realistic payloads, validate responses, and—where relevant—use contract testing (e.g. Pact) so that consumers and providers stay in sync. These tests typically run faster than full E2E and fit well in CI.

Dealing with Flaky Tests

Flaky tests undermine confidence and waste time. We help you reduce flakiness through stable selectors, explicit waits, isolated data, and clear failure messages. When a test is inherently flaky, we help you decide whether to fix it, quarantine it, or replace it with a more stable kind of test.
