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 Testing Concepts in JavaScript and Mocha
Understand the importance of tests in the application lifecycle. Distinction between unit tests, integration tests, and functional tests. Presentation of Mocha: philosophy, advantages, overview of tools (Chai, Sinon, NYC). Installation of the environment (Node.js, NPM, Mocha). Structure and conventions of tests with Mocha.
Module 2Writing Robust Tests with Mocha and Chai
Mocha test syntax: describe, it, hooks (before, after, beforeEach, afterEach). Using assertions with Chai (should, expect, assert). Handling asynchronous tests (callbacks, promises, async/await). Organizing test suites. Error handling strategies and parameterized tests. Best practices and anti-patterns.
Module 3Advanced: Coverage, CI/CD, Stubs and Mocks
Integrate code coverage tracking with NYC (Istanbul). Stubs, mocks, and spies with Sinon.js to simulate dependencies. Testing Express modules and APIs. Debugging and interpreting failure reports. Integrating tests into a CI/CD pipeline (GitHub Actions, GitLab CI). Tips for maintaining a sustainable and scalable test base.

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.
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.
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.
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.
