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.
Complete introduction to JUnit 5 in a professional setting, quick installation of the environment via Maven in IntelliJ or Eclipse, creation of your first unit test on a simple Java class, exploration of basic annotations like @Test and @BeforeEach, execution and interpretation of results with assertions such as assertEquals and assertTrue, practical exercises on real business methods to immediately validate your skills and generate functional test reports.
In-depth coverage of advanced assertions with JUnit and Hamcrest for precise verifications, management of test lifecycle via @AfterEach and @BeforeAll, organization of test suites into packages and dedicated classes, hands-on practice on an ongoing simple banking application project, interactive debugging of test failures, generation of detailed HTML reports, all to acquire skills directly applicable in the workplace and boost your productivity from day one.
Deep dive into parameterized tests to cover multiple scenarios without code duplication, use of @ParameterizedTest with @CsvSource and @MethodSource on real cases like form validation, combination with basic mocks via Mockito to isolate external dependencies, collaborative remote exercises on your personal code, coverage analysis with JaCoCo, production of deliverables ready for CI/CD integration, transforming your tests into a strategic asset for reliable and rapid development.
Seamless integration of Mockito with JUnit to simulate services and databases, exception testing with @Test and assertThrows on critical business flows, refactoring existing tests for greater robustness, practical workshops on a simulated e-commerce application with dependency injection, measurement of impact on code maintainability, export of ready-to-use Maven configurations, providing certifiable skills that reduce production bugs by 50% and accelerate career progression.
Synthesis of best practices for performant JUnit tests in a business environment, code coverage measurement with JaCoCo and minimum thresholds, integration into CI/CD pipelines via GitHub Actions or Jenkins, collective code review of tests, optimization for fast and parallel tests, finalization of the ongoing project with a complete report and certification badge, preparing you to deploy professional skills that enhance your resume and protect your team's projects from costly regressions.

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.
