Quality Strict

Quality (Strict)

Description

Strict testing, coverage, and quality requirements for coverage phase. 90% is mandatory.

Pre-Commit Requirements

BEFORE creating ANY commit (mandatory, no exceptions):

1. make fmt - Format code
2. make check - ALL tests pass (100%)
3. make lint - ALL complexity/file size checks pass
4. make check-coverage - ALL metrics (lines, functions, branches) at 90.0%
5. make check-dynamic - ALL sanitizer checks pass (ASan, UBSan, TSan)

If ANY check fails: fix ALL issues, re-run ALL checks, repeat until everything passes.

Never commit with ANY known issue - even "pre-existing" or "in another file".

Test Execution

By Default: Tests run in parallel, with 24 parallel tests on this machine.

• MAKE_JOBS=24 - up to 24 concurrent tests
• PARALLEL=1 - all 4 check-dynamic subtargets in parallel

When you need clear debug output (serialize execution):

PARALLEL=0 MAKE_JOBS=1 make check
PARALLEL=0 MAKE_JOBS=1 make check-valgrind

Best practice: Test individual files during development, run full suite before commits.

Example:

make build/tests/unit/array/basic_test && ./build/tests/unit/array/basic_test

Build Modes

make BUILD={debug|release|sanitize|tsan|coverage}

• debug - Development builds with symbols
• release - Optimized production builds
• sanitize - Address and undefined behavior sanitizers
• tsan - Thread sanitizer
• coverage - Code coverage analysis

Quality Gates

• Use make check to verify tests while working on code changes
• Use make lint && make check-coverage before commits - 90% coverage is MANDATORY
• CRITICAL: Never run multiple make commands simultaneously. Different targets use incompatible compiler flags and will corrupt the build.

Coverage Phase Mindset

• Every uncovered line is a bug waiting to happen
• Every untested branch is a failure mode you haven't verified
• LCOV exclusions are a last resort, not a shortcut
• Zero tolerance for coverage gaps
