Learning objectives

  • Master the new features of JUnit 2026 to design ultra-high-performance unit tests in a professional context.
  • Develop custom extensions to boost automated testing skills for the enterprise.
  • Optimize parallel and dynamic test suites to accelerate certified development cycles.
  • Implement advanced mocking and injection strategies for resilient production tests.
  • Design detailed test reports integrating Jest and JUnit for exemplary professional traceability.
  • Deploy JUnit 2026 in Selenium and Cypress CI/CD pipelines, strengthening team certification skills.

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.

Conduct benchmarks on virtual clusters, integrate with Jest for hybrid JS assertions, and analyze bottlenecks with built-in profilers. Perform hands-on labs on scalable microservices, produce reproducible configurations, and apply best practices for 10x faster tests in certified professional environments.

Module 4Advanced JUnit 2026 Integrations: Selenium, Cypress, and Playwright (Hybrid Testing, Pipelines)

Integrate JUnit 2026 with Selenium for E2E unit tests, Cypress for fluid scripts, and Playwright for cross-browser testing in GitHub Actions pipelines. Develop hybrid runners with semantic tags, manage adaptive timeouts, and automate visual assertions. Work on real critical web app cases, generate unified dashboards, and deploy modular setups to boost enterprise automated testing skills.

Module 5JUnit 2026 Best Practices and Deployment: Reports, Monitoring, and Certification (Jest/JUnit, Final Project)

Synthesize JUnit 2026 best practices for production monitoring with custom listeners, integrating Jest for unified coverage and JUnit XML for CI tools. Complete a final project on a legacy app migration, produce a certifying report with KPI metrics, and simulate Qualiopi audits. Optimize for legacy code, discuss anti-fragile patterns, and receive a personalized action plan for immediate team deployment.

Evaluation method

  • Daily technical quizzes on JUnit 2026 new features with automated scoring.
  • 4-hour capstone project: expert test suite deployed in real CI/CD.
  • Peer-review evaluation and Qualiopi certification validating advanced skills.

Learning method

  • Intensive hands-on practice on live code with shared IDEs in-person.
  • Case studies from Fortune 500 companies migrated to JUnit 2026.
  • Individual mentoring by certified experts for advanced debugging.
  • Real-time CI/CD pipeline simulations with Selenium and Cypress tools.

Methods, materials and delivery

The Training JUnit 2026 - Mastering High-Performance 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 JUnit 2026 - Mastering High-Performance 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 JUnit 2026 - Mastering High-Performance 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.
