Learning objectives

  • Master the fundamentals of JUnit 5 for professional and certifiable unit tests
  • Develop reliable test suites adapted to business projects
  • Implement essential annotations and assertions to validate Java code
  • Design parameterized and mocked tests for optimal coverage
  • Integrate JUnit into a modern development workflow with Maven or Gradle
  • Optimize unit tests to accelerate team development cycles

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.

Program

Module 1JUnit Fundamentals: Installation and First Tests (JUnit 5, Maven, IDE)

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.

Module 2Assertions and Organization: Structuring Robust JUnit Tests (Hamcrest, Lifecycle)

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.

Module 3Parameterized JUnit Tests: Varying Input Data (ParameterizedTest, CsvSource)

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.

Module 4Mocks and Exceptions in JUnit: Managing Dependencies (Mockito, assertThrows)

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.

Module 5JUnit Best Practices: Coverage and CI/CD (JaCoCo, GitHub Actions)

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.

Evaluation method

  • Quiz to validate acquired knowledge on JUnit at the end of the training
  • Continuous evaluation through practical exercises and ongoing project
  • Oral defense of the unit tests project in front of the expert trainer

Learning method

  • Courses led by an active expert Java trainer
  • Practical exercises on real business cases with JUnit
  • Progressive ongoing project throughout the training
  • Complete course materials provided to each participant

Methods, materials and delivery

The Training JUnit - Mastering Unit Tests in Java 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 - Mastering Unit Tests in Java 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 - Mastering Unit Tests in Java 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.
