Program

Module 1Advanced Unit Testing: Mocks, Stubs, and Dependency Isolation (JUnit, Mockito, pytest)

Discover advanced isolation techniques through hands-on workshops using JUnit and Mockito for Java, or pytest for Python, simulating databases and external APIs. Analyze real e-commerce application cases, create parameterized mocks for testing asynchronous behaviors, measure coverage with JaCoCo or Coverage.py, produce detailed reports and deliverables ready to integrate into your professional codebase, while optimizing test execution speed.

Module 2Unit Testing Strategies: Expert TDD, Refactoring, and CI/CD Integration (GitHub Actions, Jenkins)

Dive into advanced TDD with complex katas like Game of Life or microservices. Refactor legacy test suites to make them maintainable, integrate them into CI/CD pipelines using GitHub Actions and Jenkins, test edge cases with data generators, evaluate robustness via mutation testing with PITest, collaborate in pairs on simulated enterprise projects, generate coverage badges for dashboards, and leave with a certifiable portfolio of deployable unit tests.

Evaluation method

  • Technical MCQ on mocks and TDD with an 80% passing score
  • Practical case study: refactoring a real-world test suite
  • Final project evaluated by an expert: implementing a CI/CD pipeline with unit tests

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.
