Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Dive into the evolutions of Mocking 2026 with expert environment setup, creating mocks for REST and GraphQL APIs, practical exercises on real network dependencies, using MSW for browser-side interceptions, developing dynamic stubs tailored to concrete business cases, and generating test coverage reports to validate professional skills.
Deepen stubbing with Sinon.js for timers and promises, implement spies on private methods and Node.js modules, practice on Dockerized microservices, test complex asynchronous flows with awaits and generators, analyze mock performance via integrated profilers, and generate testable deliverables for certified enterprise portfolios.
Design persistent fakes for NoSQL and SQL databases using Prisma and Supertest, simulate AWS/Azure cloud error scenarios, integrate mocks into GitHub Actions pipelines, develop mocked end-to-end tests for full-stack applications, optimize resilience with retry mechanisms, and produce an ongoing project demonstrating production-ready expert skills.
Deploy mocks in CI/CD with Playwright and Vitest, measure quality using Istanbul and codecov, refactor legacy test suites for Mocking 2026, integrate automated cleanup hooks, simulate multi-platform environments, and conclude with a collective code review and certification plan to boost enterprise skills.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
