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 creating sophisticated mocks to perfectly isolate external dependencies in your unit tests, configure spies to monitor function calls and validate precise interactions, apply these techniques to concrete enterprise application cases with personalized code review, produce robust test suites, and create a first deliverable: a fully mocked, tested, and documented module.
Analyze the coverage of your unit tests in depth using professional tools like Istanbul and SonarQube, identify uncovered areas in enterprise legacy code, implement strategies to achieve 90% coverage without overloading suites, practice on real projects with automated report generation, and finalize an optimization plan with GitHub badges to demonstrate your advanced unit testing skills.
Adopt a rigorous Test-Driven Development approach to design unit tests from the specification phase, chain complex katas on enterprise business scenarios such as secure user management, refactor iteratively for clean and maintainable codebases, integrate advanced assertions with Chai or Jest matchers, and produce a red thread project where every feature is validated by certifiable and performant unit tests.
Master the pitfalls of unit testing asynchronous code by simulating APIs with nock and MSW, test complex flows including promise chains and network error handling, apply timeouts and retries for professional robustness, practice on real enterprise microservices, and generate performance reports with advanced HTTP mocks, resulting in a deliverable: a unit test suite covering 100% of asynchronous edge cases.
Configure complete CI/CD pipelines to run your unit tests on every commit, integrate mandatory coverage thresholds with GitHub Actions or Jenkins, analyze flakes and stabilize suites for reliable production deployments, test on simulated enterprise repos with parallelization and caching, and deploy a ready-to-use workflow with documentation, enhancing your certifiable skills in automated software quality.
The Unit Testing Training - Mastering Advanced Automated 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.
For the smooth delivery of the Unit Testing Training - Mastering Advanced Automated Tests program, the following equipment is required:
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.
Assessment of skills acquired during the Unit Testing Training - Mastering Advanced Automated Tests program is performed through:

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.
