Learning objectives

  • Understand the fundamentals of unit and functional tests for JavaScript
  • Install, configure, and use Mocha to set up automated test suites
  • Write effective unit, integration, and functional tests
  • Leverage assertions with Chai to enrich test scenarios
  • Practice mocking and stubbing to isolate tested functionalities
  • Integrate Mocha tests into continuous integration workflows (CI/CD)
  • Analyze code coverage reports and improve software quality

Our social commitment

A school kit donated to a child for every training

To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.

  • Backpack, notebooks and essential supplies
  • Distributed through our partner charities
  • Included, at no extra cost to you

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

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 1Introduction to Automated Tests and Getting Started with Mocha

1. Why test? Presentation of key concepts: unit test, integration test, functional test. 2. Installation and configuration of Mocha (local environment and Node.js/front-end project). 3. Structure of a test with Mocha: describe(), it(), before(), after(). 4. Getting started with first assertions using Chai. 5. Practical exercises on setting up a test environment and first tests on simple functions.

Module 2Deep Dive and Structuring Test Suites

1. Writing and organizing complex test suites (files, nested describe, advanced hooks). 2. Using Chai: assert, expect, should, exception handling. 3. Handling asynchronous tests: promises, callbacks, async/await. 4. Mocking and stubbing practice with Sinon.js. 5. Practical exercises: REST API testing, dependency isolation, time manipulation, exception verification.

Module 3Industrialization, Continuous Integration, and Test Optimization

1. Generating test reports and code coverage with Istanbul (nyc) and Mocha. 2. Setting up a scalable test strategy, TDD/BDD concepts. 3. Integrating tests into CI/CD workflows (GitHub Actions, Gitlab CI, Jenkins). 4. Best practices for maintaining a tested and maintainable codebase: refactoring, test maintenance, handling false positives/negatives. 5. Practical cases on Node.js or front-end (React/Vue) application project, correction of the red thread project followed throughout the training.

Evaluation method

  • MCQ at the end of each day
  • Red thread project to complete (tests on a complete application created during the training)
  • Correction and personalized feedback at the end of the course

Learning method

  • Lectures illustrated with live demonstrations
  • Guided exercises and case studies
  • Test development on a real project as a common thread
  • Provision of detailed course materials and Mocha/Chai/Sinon test templates

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

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.
