Modern test framework
Coverage patterns
Code coherence detection
Modern runtime
Everything you need to hire junit engineers
Live JUnit 5 execution, parameterization questions, and integrity detection for Java testing.
Live JUnit 5 execution
Candidates write and run parameterized and lifecycle-aware tests inside the assessment.
JUnit 5 MCQ library
Curated questions on parameterized tests, @ParameterizedTest, custom extensions, lifecycle callbacks, and assertions.
Parameterized test execution
Real JUnit execution with @ParameterizedTest, @CsvSource, @ValueSource, and custom argument providers.
AI code review
Claude-powered analysis of test coverage, assertion quality, and lifecycle management.
Pair-programming interviews
LiveKit video + collaborative editor for live test-writing sessions.
AI-proof integrity
Code coherence AI flags ChatGPT-generated tests; keystroke biometrics catch takeovers.
JUnit templates
Parameterized, nested, and custom-extension JUnit templates ready to go.
Time analytics
Measure time-per-test to calibrate difficulty.
Built-in pipeline
Job posts, kanban pipelines, structured feedback, PDF reports.
Built for JUnit hiring, end to end
Skill signal, integrity, and pipeline — all in one platform.
Test JUnit mastery and test design
Great JUnit engineers leverage parameterization for coverage and custom extensions for setup. ClarityHire runs live JUnit so you see actual test-design skill.
- Parameterized test design and argument providers
- Lifecycle callbacks (@BeforeEach, @BeforeAll)
- Custom extensions and test conditions (@EnabledIf, @Tag)
Catch ChatGPT-generated code before you hire
LLM-generated code arrives as large clean pastes with no iterative debugging. Authentic coding shows typing rhythm, edits, and refactors. Code coherence AI plus keystroke biometrics score the session, not just the output.
- Edit pattern analysis (type → test → refactor)
- Keystroke biometrics detect takeovers mid-session
- Per-signal authenticity score on every submission
From application to offer in one platform
Post the role, invite candidates, run assessments, schedule live interviews, collect structured feedback, and export a PDF report — all without leaving ClarityHire. No stitched-together ATS, video tool, and assessment platform.
- Job boards with branded careers page
- Kanban pipelines with stage automations
- PDF hiring reports for stakeholders
From posting to offer in four steps
Post the role
Use a ready-made template or build from scratch. Embed the posting on your branded careers page in minutes.
Invite candidates
Send assessments by email or CSV bulk import. Each candidate gets a unique, revocable token-protected link.
They build, you watch
Candidates code in a real Monaco editor with integrated execution. Integrity signals run silently in the background.
Interview + offer
Top candidates advance to a collaborative video interview. Structured feedback, PDF report, offer letter.
Frequently asked questions
What JUnit topics can I assess?+
Parameterized tests (@ParameterizedTest, @CsvSource, @ValueSource), custom extensions, lifecycle callbacks (@BeforeEach, @AfterEach, @BeforeAll), assertions, test naming, nested test classes, and parameterized test organization.
Can candidates use custom argument providers?+
Yes. JUnit 5 custom ArgumentsProvider implementations work in the live editor. Candidates can implement reusable test data generators.
How do you detect if a candidate used ChatGPT or Copilot?+
Code coherence AI analyzes the edit pattern of every session. LLM-generated code typically arrives as large clean pastes with no iterative debugging — those patterns get flagged with evidence. Keystroke biometrics catch takeovers mid-session, and paste events are logged with code-size correlation.
Can I run live pair-programming interviews?+
Yes. LiveKit-powered video plus a collaborative Monaco editor (Yjs CRDT) lets you and the candidate co-edit in real time. Recording, transcription, and structured scorecards are built in.
Do I still need a separate ATS?+
No. ClarityHire includes job boards, candidate pipelines, stage automations, bulk CSV import, and PDF reports. Most teams replace their ATS + assessment tool + interview platform with a single ClarityHire subscription.
