Fred Hauschel
Last position:
Software Architect and Developer at Personal project
A recurring problem in my own AI-supported projects: requirements analysis, use cases, and architecture decisions can be created quickly with AI support, but they remain hard to trace and scattered across Markdown files – knowledge is lost as soon as it is no longer in the context window. arknet turns requirements engineering and architecture knowledge into structured, verifiable data instead of plain text: requirements, use cases, and architecture decisions as a continuously linked knowledge graph, traceable from the requirement to the architecture decision – queryable for both people and AI agents alike. Technically based on RDF/OWL and its own MCP server.
Result: MCP daemon running, Docker image automatically published on GHCR, nine hexagonal modules, eleven ADRs (including an open-core licensing model). Requirements engineering and ubiquitous language hexagon active. Publicly available since 07/2026 as a Community Edition under Apache-2.0 (github.com/kogn-io/arknet), together with the Claude Code plugin and the GHCR image; open-core model.
Label: Java, Maven, RDF, RDF4J, OWL, SPARQL, Model Context Protocol, Spring AI, Docker, GitHub, Git, Claude Code, Obsidian, DDD, Hexagonal Architecture, ArchUnit, JUnit, AssertJ

About the technology
Test foundations
JUnit is the standard testing framework for Java. It is used to write unit tests, verify business rules, and protect code during refactors. Teams rely on it to keep backend services, libraries, and build pipelines stable.
What experts deliver
- Clean test suites for Java applications
- JUnit 5 and JUnit Jupiter migration work
- Assertions, parameterized tests, and test lifecycle setup
- Integration with Maven, Gradle, and CI checks
Strong specialists know when a test should stay small and when a wider test belongs in the suite.
Ecosystem skills
JUnit usually sits next to Mockito, AssertJ, Hamcrest, Testcontainers, and Spring Test. Good professionals understand test doubles, fixture design, and how to keep tests readable as systems grow. They also know how to fit JUnit into a clean build process.
When to bring help
Companies bring in freelance expertise when tests are missing, flaky, or hard to maintain. That often happens during Java modernization, CI hardening, or a move from JUnit 4 to JUnit 5. In Munich, this is common in software teams that need short, focused support without slowing product work.
What good work looks like
- Tests cover real behavior, not implementation noise
- Names explain intent clearly
- Setup is small and reusable
- Failures point to a real defect quickly
A strong JUnit specialist writes tests that support change instead of blocking it.
Local delivery
JUnit work can be done fully remote, which suits most Java teams well. On-site sessions in Munich help when the codebase is large, the team wants shared testing standards, or migration decisions need close discussion. Clear communication in English, and sometimes German, is often enough for smooth delivery.
Frequently asked questions
Key details about JUnit, drawn from the questions we get asked most.
JUnit is used to write automated tests for Java code, especially unit tests that check one class or one behavior at a time. It also supports broader testing patterns when a team needs integration checks around services, repositories, or APIs.
JUnit 5 is the modern choice for most new work because it gives teams a more flexible API and a clearer extension model. JUnit 4 still appears in older codebases, so many freelancers are hired to migrate tests gradually without breaking the build.
JUnit is the default testing framework in many Java teams, while TestNG is often chosen for its different annotations and test grouping style. In practice, the right choice depends on the existing codebase, the build setup, and whether the team wants a standard path that fits the wider Java ecosystem.
A strong JUnit specialist usually also knows Mockito, AssertJ, and sometimes Testcontainers or Spring Test. They should be comfortable with Maven or Gradle, CI pipelines, and basic design choices that make tests easier to maintain.
JUnit help is most useful when tests are sparse, brittle, or slow to run, or when a Java team is cleaning up a legacy codebase. It is also valuable during framework upgrades, release hardening, and before a larger refactor.
Yes. JUnit tasks are often well suited to remote work because they center on code review, test writing, and build feedback. On-site time in Munich can still help when teams want direct workshops or need to align on testing conventions quickly.
Look for tests that are readable, stable, and tied to business behavior. Good JUnit work avoids over-mocking, keeps setup tidy, and makes failures easy to understand, which matters more than chasing test volume.
JUnit Jupiter is the programming and extension model introduced with JUnit 5. It is what most specialists use today for writing tests, while the older JUnit 4 style remains in many legacy systems and may still need support during migration.
The average hourly rate of freelancers in Munich, Germany who have used JUnit in their recent projects is 91 €, which corresponds to a daily rate of about 732 € based on an 8-hour working day.
