The Learni story

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

Why this program matters

  • 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.

Program

Module 1Advanced Fundamentals of Mocking 2026: API and Dependency Simulation (Jest, WireMock, Native Tools)

Dive into Mocking 2026 protocols to faithfully recreate external APIs, install and configure advanced Jest with MSW to intercept HTTP requests, perform exercises on real microservices, create your first dynamic mocks with regex patterns, test error and timeout scenarios, produce an initial coverage report, and optimise for fast enterprise deployments.

Module 2Stubs and Spies in Mocking 2026: Asynchronous State Management (Sinon.js, Nock, Promises)

Explore smart spies in Mocking 2026 to track calls and arguments, integrate Sinon.js into async flows with async/await, simulate NoSQL databases via persistent mocks, practice on real e-commerce cases with network delays, generate conditional stubs based on inputs, analyse test performance metrics, and validate deliverables ready for GitHub Actions in professional teams.

Module 3Scalable Mocks in Mocking 2026: CI/CD and Container Integration (Docker, Kubernetes Mocks)

Design containerised mocks with Mocking 2026 for Kubernetes, deploy isolated test environments via Docker Compose, automate mocked pipelines with GitLab CI, test inter-service interactions on ongoing projects, implement reusable mock factories, measure impact on 50% reduced build times, and document certified configurations for Qualiopi audits in enterprises.

Module 4Resilient Tests with Mocking 2026: Edge Cases and Security (OWASP Mocks, Fuzzing)

Master secure mocks in Mocking 2026 against injections and leaks, integrate OWASP ZAP to validate simulated vulnerabilities, practice advanced fuzzing on GraphQL APIs, generate realistic attack scenarios with chaos engineering, optimise for 95% edge case coverage, analyse real-time mock logs, and produce a business-ready remediation plan for DevSecOps teams.

Module 5Optimisation and Deployment with Mocking 2026: Monitoring and Best Practices (Prometheus, ELK)

Finalise your expertise with mock monitoring via Prometheus in Mocking 2026, integrate ELK Stack for test dashboards, conduct code review on the complete ongoing project, optimise for zero flakiness in production-like environments, deploy Git hooks for auto-generated mocks, evaluate ROI with quantified metrics, and leave with certified skills ready to boost enterprise deployments.

Evaluation method

  • Expert MCQ on Mocking 2026 protocols and advanced tools
  • Practical evaluation via ongoing mocked project in CI/CD
  • Oral defence of deployed mocking strategies

Learning method

  • Courses by expert trainer in mocking for major accounts

  • Digital learning support and provided source code

Methods, materials and delivery

The Training Mocking 2026 - Optimising Advanced Unit Tests program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training Mocking 2026 - Optimising Advanced Unit Tests program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Training Mocking 2026 - Optimising Advanced Unit Tests program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Learni programs are available inter-company and intra-company, onsite or remote. Enrollments are possible up to 48 business hours before the program starts. Our programs are eligible for corporate funding paths. Contact us to discuss your training project and funding options.

Our method

Training quality, guaranteed at every step

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
