Testing, Debugging, and Production Readiness

Prove that running software behaves correctly and decide whether it can ship. Independent verification and test-level choice, evaluating AI-written tests, systematic debugging and root-cause analysis, defect triage, regression evidence, readiness gates, rollback plans, and a defensible ship or no-ship decision.

By the end of this Course, you can verify a running feature against its claims independently, debug a reported failure to a confirmed root cause, prevent its return with regression evidence, and produce a readiness record that supports a defensible ship or no-ship decision.

01Verify behavior independently — derive every expected result from the stated claim rather than from the implementation that produced it
02Turn a design specification and a change intent into falsifiable claims, then choose the lowest test level that can actually falsify each one
03Write unit, integration, and end-to-end verification that fails for the right reason and stays readable a year later
04Evaluate an AI-written test the way a skeptic would: mirror assertions, incidental strings, mocked-away subjects, and assertions that can never fail
05Read coverage honestly — what executing a line proves, what it does not, and why a coverage number is never a readiness gate
06Debug systematically from a reproducible failure to a confirmed root cause, instead of changing code until the symptom disappears
07Triage defects by user impact and blast radius, and turn each confirmed fix into a regression test that would have caught it
08Assemble a readiness record — evidence, residual risk, rollback plan, monitoring — and make a ship or no-ship decision you can defend

What You'll Gain
  • Turns "the tests passed" into a claim you can defend line by line to the person who gets paged at 3am
  • Treats AI-written tests as evidence to be audited rather than work already done
  • Separates what a passing check actually proves from what a release summary would prefer to imply
  • Uses worked code examples and scenario-based assessments drawn from real release decisions
Who Is This Course For?
  • Design Engineers who can implement and review a change and now have to prove the running software actually works
  • UX and product designers who own a feature end to end and must decide, with evidence, whether it is safe to release
  • Designers working with AI-generated code who need to judge whether a generated test proves anything at all
  • Anyone approaching the Design Engineer Capstone, where a production-ready slice must be defended live
Course Features
  • 3 progressive Levels and 30 substantive bilingual Lessons
  • Worked, untranslated code examples in every implementation-heavy Lesson
  • 30 Lesson Quizzes with 10 scenario-based questions each
  • 3 Level Exams with 15 transfer questions each
