Why this program matters

  • Without mastery of unit tests in Java, 68% of bugs escape development and surface in production, multiplying correction costs by 100 according to the NIST institute.

  • Each incident costs a company an average of 8 000 €, with 40% of developers' time lost to urgent debugging, slowing deliveries and growth.

  • Your untested code exposes the company to critical security breaches and customer loss, while your career stagnates against more reliable competitors.

  • Every month without solid skills amplifies these risks, turning promising projects into costly failures.

Our method

How Learni guarantees the quality of your Unit Tests in Java with JUnit training

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.
