Why this program matters

Without mastery of Mockito 2026, 70% of unit tests fail in production, generating bugs that cost 50 000€ per incident according to Standish Group reports.
Teams lose 35% of time on manual debugging, delaying deliveries and impacting company revenue.
In 2026, 82% of Java recruiters reject profiles without advanced mocking skills, blocking promotions and career moves.
Every quarter without training widens the competitive gap, exposes teams to security vulnerabilities, and multiplies maintenance costs by 4.

Learning objectives

Master the fundamentals of Mockito 2026 for professional unit tests
Develop skills in creating certifying mocks and stubs
Configure interaction verifications in enterprise projects
Implement spies and Mockito annotations for optimal coverage
Optimize unit tests with Mockito in CI/CD environments
Design robust test suites tailored to professional training

Program

Module 1Mockito 2026 Fundamentals: installation and first mocks (Maven, Gradle, JUnit)

Dive into the world of Mockito 2026 by installing the environment via Maven or Gradle, create your first professional unit test project, explore the @Mock and @InjectMocks annotations to simulate real dependencies, perform practical exercises on simple Java classes, produce basic mocks and validate essential interactions with the trainer for a solid and confident foundation.

Module 2Stubbing with Mockito 2026: simulating behaviors and responses (when/thenReturn, ArgumentMatchers)

Learn to stub methods with when().thenReturn() to anticipate all scenarios, use ArgumentMatchers for flexible mocks on varied parameters, apply these techniques to concrete enterprise cases like web services, chain exercises on complex business flows, generate test reports and optimize your code for easy and performant maintenance from day one.

Module 3Verifications with Mockito 2026: validating interactions and spies (verify, ArgumentCaptor)

Master verify() to control method calls and their precise order, integrate spies to partially test real objects, capture complex arguments with ArgumentCaptor in advanced tests, work on examples inspired by enterprise legacy code, perform collaborative lab sessions to detect hidden bugs, and document your verifications for certifying and professional traceability.

Module 4Ongoing Project with Mockito 2026: advanced tests and CI/CD integration (BDDMockito, complete project)

Finalize a complete ongoing project integrating all Mockito 2026 tools, transition to BDDMockito for a narrative and readable test style, configure integration in Jenkins or GitHub Actions for smooth CI/CD, test realistic exceptions and timeouts, collectively review the code with expert feedback, deliver a certifying test suite ready for production and boost your professional skills immediately.

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.
