# Generate coverage report
./scripts/coverage-report.sh

# Review report
cat coverage/coverage-report.md

# Identify gaps
grep "❌" coverage/coverage-report.md

Output:

• Coverage percentages
• Untested files list
• Recommendations

# Generate stubs for all untested files
./scripts/generate-missing-tests.sh

# Review generated files
ls -la src/tests/unit/cli/
ls -la src/tests/unit/lib/

Output:

• Test skeleton files in src/tests/unit/
• Executable permissions set
• Placeholder tests to implement

# Edit generated test file
vim src/tests/unit/cli/test-doctor.sh

# Replace skip_test placeholders with actual tests
# Example:
test_doctor_checks_docker() {
  # Was: skip_test "Not implemented yet"

  # Now:
  local output
  output=$(bash "$CLI_COMMAND" 2>&1)
  assert_contains "$output" "Docker"
}

Reference:

• Use patterns from TESTING-QUICK-START.md
• Source enhanced framework: test-framework-enhanced.sh
• Use mocks when needed: mock-infrastructure.sh

# Run specific test
./src/tests/unit/cli/test-doctor.sh

# Run all CLI tests
find src/tests/unit/cli -name "test-*.sh" -exec {} \;

# Run all unit tests
find src/tests/unit -name "test-*.sh" -exec {} \;

Output:

• Test results (pass/fail/skip)
• Test summary
• Exit code (0 = all passed)

# Re-run coverage report
./scripts/coverage-report.sh

# Compare to previous report
diff coverage/coverage-report-old.md coverage/coverage-report.md
