Use whenever you want to implement with TDD — whether a new feature, a bugfix, a refactor, or any behavior change.\nargument-hint: \"[feature, bug, or behavior to implement]\"\ndisable-model-invocation: true\n---\n\n# Test-Driven Development (TDD)\n\n## Overview\n\nWrite the test first. Watch it fail. Write minimal code to pass.\n\n**Core principle:** If you didn't watch the test fail, you don't know if it tests the right thing.\n\n**Violating the letter of the rules is violating the spirit of the rules.**\n\n## The Iron Law\n\n```\nNO PRODUCTION CODE WITHOUT A FAILING TEST FIRST\n```\n\nWrite code before the test? Delete it. Start over.\n\n**No exceptions:**\n\n- Don't keep it as \"reference\"\n- Don't \"adapt\" it while writing tests\n- Don't look at it\n- Delete means delete\n\nImplement fresh from tests. Period.\n\n## Outside-In Development\n\nStart every feature with a high-level test that describes behavior from the user's perspective. Run it, read the failure, and let that failure dictate your next move. As failures push you down the stack, write a new failing test at each layer you drop into — never write code for a layer without a failing test at that layer demanding it.\n\nRead `examples/outside-in-testing.md` for a walkthrough of the philosophy and `examples/testing-pyramid.md` for how test types combine into an optimal suite.\n\n### One Change, One Run\n\nAfter every change — writing a test, adding a route, creating a file, implementing a method — run the affected test immediately:\n\n```bash\nbundle exec rspec spec/features/guest_searches_for_items_spec.rb\n```\n\nThe failure message is your instruction for what to do next. Don't batch changes and don't guess ahead: one change, one run, read the failure, decide. If you made two changes before running, you no longer know which one the test is reacting to.\n\n### Drop Down by Writing the Next Failing Test\n\nA failure rarely means \"write this exact line.\" It usually means \"the layer below isn't there yet.\" When the active test's failure points to a layer that has behavior of its own — a controller action, an endpoint, a model method — **drop down and write a failing test at that layer before building it.**\n\nThink of it as a stack of failing tests:\n\n- The **active** test is the one whose failure you're reading right now.\n- Its failure points to a missing lower layer → write a new failing test at that layer. It becomes the active test.\n- Drive that test with Red-Green-Refactor. If _it_ forces you down another level, push another failing test.\n- When the active test goes green, pop it: rerun the test one layer up. Its next failure drives the next move.\n\nDrop to whichever layer the failure names — not always one rung at a time. Continue until the top-level feature spec is green with nothing left on the stack.\n\nThe ladder of test types, top to bottom:\n\n| When the failure points to…                                         | Write this failing test      |\n| ------------------------------------------------------------------- | ---------------------------- |\n| End-to-end behavior from the user's perspective                     | Feature / system spec        |\n| A controller action, response, status, or redirect                  | Request (or controller) spec |\n| Logic in a model, service object, query, calculation, or validation | Model / unit spec            |\n\nFeature and request specs are integration tests: real database records, no mocks — except external services (use webmock or fakes), so the suite runs offline. Unit specs isolate the object under test: mock collaborators aggressively, because the goal is to prove _this_ object, not its collaborators. Difficulty testing two objects in isolation signals too-tight coupling.\n\n### Build Directly Only for Inert Glue\n\nA few things have no behavior of their own, so they get no test of their own — but you still add them only because a failing test one layer up demanded them:\n\n- The route line (a request spec failing with `No route matches` drives it)\n- An empty class or module to clear a `NameError`\n- Trivial markup a feature spec's content expectation already covers\n\nEverything with behavior gets its own failing test first. When in doubt, drop down and write the test.\n\nThe testing pyramid: many unit tests at the bottom, fewer request specs in the middle, a few feature specs at the top. Unit tests are fast and precise; feature tests prove the system works end-to-end. Each plays to its strengths.\n\n## Red-Green-Refactor\n\nThe cycle every test follows — feature spec, request spec, and model spec alike. Each failing test on the stack runs this loop; a test going green is what lets you pop back up to the layer above.\n\n```dot\ndigraph tdd_cycle {\n    rankdir=LR;\n    red [label=\"RED\\nWrite failing test\", shape=box, style=filled, fillcolor=\"#ffcccc\"];\n    verify_red [label=\"Verify fails\\ncorrectly\", shape=diamond];\n    green [label=\"GREEN\\nMinimal code\", shape=box, style=filled, fillcolor=\"#ccffcc\"];\n    verify_green [label=\"Verify passes\\nAll green\", shape=diamond];\n    refactor [label=\"REFACTOR\\nClean up\", shape=box, style=filled, fillcolor=\"#ccccff\"];\n    next [label=\"Next\", shape=ellipse];\n\n    red -> verify_red;\n    verify_red -> green [label=\"yes\"];\n    verify_red -> red [label=\"wrong\\nfailure\"];\n    green -> verify_green;\n    verify_green -> refactor [label=\"yes\"];\n    verify_green -> green [label=\"no\"];\n    refactor -> verify_green [label=\"stay\\ngreen\"];\n    verify_green -> next;\n    next -> red;\n}\n```\n\n### RED — Write Failing Test\n\nWrite one minimal test showing what should happen.\n\n<Good>\n\n```ruby\nRSpec.describe Item, \".search\" do\n  it \"filters items by the search term\" do\n    desired_item = create(:item, name: \"Widget\")\n    _other_item = create(:item, name: \"Gadget\")\n\n    expect(Item.search(\"Widget\")).to eq [desired_item]\n  end\nend\n```\n\nClear name, tests real behavior, one thing.\n\n</Good>\n\n<Bad>\n\n```ruby\nit \"search works\" do\n  relation = spy(\"relation\")\n  allow(Item).to receive(:where).and_return(relation)\n\n  Item.search(\"Widget\")\n\n  expect(Item).to have_received(:where).with(name: \"Widget\")\nend\n```\n\nVague name, tests spy interactions not real behavior, proves nothing about whether search actually returns the right items.\n\n</Bad>\n\n**Requirements:**\n\n- One behavior\n- Clear name\n- Feature specs: real records, no mocks (except external services)\n- Unit tests: mock collaborators, test the object in isolation\n\n### Verify RED — Watch It Fail\n\n**MANDATORY. Never skip.**\n\n```bash\nbundle exec rspec spec/models/item_spec.rb\n```\n\nConfirm:\n\n- Test fails (not errors)\n- Failure message is expected\n- Fails because feature missing (not typos)\n\n**Test passes?** You're testing existing behavior. Fix test.\n\n**Test errors?** Fix error, re-run until it fails correctly.\n\n### GREEN — Minimal Code\n\nWrite simplest code to pass the test.\n\n<Good>\n\n```ruby\nclass Item < ApplicationRecord\n  def self.search(term)\n    where(name: term)\n  end\nend\n```\n\nJust enough to pass.\n\n</Good>\n\n<Bad>\n\n```ruby\nclass Item < ApplicationRecord\n  def self.search(term, fuzzy: false, limit: nil, scope: :all)\n    # YAGNI — the test asked for name filtering, not a search framework\n  end\nend\n```\n\nOver-engineered.\n\n</Bad>\n\nDon't add features, refactor other code, or \"improve\" beyond the test.\n\n### Verify GREEN — Watch It Pass\n\n**MANDATORY.**\n\n```bash\nbundle exec rspec spec/models/item_spec.rb\n```\n\nConfirm:\n\n- Test passes\n- Other tests still pass\n- Output pristine (no errors, warnings)\n\n**Test fails?** Fix code, not test.\n\n**Other tests fail?** Fix now.\n\n### REFACTOR — Clean Up\n\nAfter green only:\n\n- Remove duplication\n- Improve names\n- Extract helpers\n\nKeep tests green. Don't add behavior.\n\n### Repeat\n\nPop the stack. Rerun the test one layer up and read its next failure — it drives the next move: build inert glue, or push a new failing test for the next layer down. Keep going until the top-level feature spec is green and the stack is empty.\n\n## Good Tests\n\n| Quality          | Good                                | Bad                                              |\n| ---------------- | ----------------------------------- | ------------------------------------------------ |\n| **Minimal**      | One thing. \"and\" in name? Split it. | `it \"validates email and domain and whitespace\"` |\n| **Clear**        | Name describes behavior             | `it \"test1\"`                                     |\n| **Shows intent** | Demonstrates desired API            | Obscures what code should do                     |\n\n## Why Order Matters\n\n**\"I'll write tests after to verify it works\"**\n\nTests written after code pass immediately. Passing immediately proves nothing:\n\n- Might test wrong thing\n- Might test implementation, not behavior\n- Might miss edge cases you forgot\n- You never saw it catch the bug\n\nTest-first forces you to see the test fail, proving it actually tests something.\n\n**\"I already manually tested all the edge cases\"**\n\nManual testing is ad-hoc. You think you tested everything but:\n\n- No record of what you tested\n- Can't re-run when code changes\n- Easy to forget cases under pressure\n- \"It worked when I tried it\" ≠ comprehensive\n\nAutomated tests are systematic. They run the same way every time.\n\n**\"Deleting X hours of work is wasteful\"**\n\nSunk cost fallacy. The time is already gone. Your choice now:\n\n- Delete and rewrite with TDD (X more hours, high confidence)\n- Keep it and add tests after (30 min, low confidence, likely bugs)\n\nThe \"waste\" is keeping code you can't trust. Working code without real tests is technical debt.\n\n**\"TDD is dogmatic, being pragmatic means adapting\"**\n\nTDD IS pragmatic:\n\n- Finds bugs before commit (faster than debugging after)\n- Prevents regressions (tests catch breaks immediately)\n- Documents behavior (tests show how to use code)\n- Enables refactoring (change freely, tests catch breaks)\n\n\"Pragmatic\" shortcuts = debugging in production = slower.\n\n**\"Tests after achieve the same goals — it's spirit not ritual\"**\n\nNo. Tests-after answer \"What does this do?\" Tests-first answer \"What should this do?\"\n\nTests-after are biased by your implementation. You test what you built, not what's required. You verify remembered edge cases, not discovered ones.\n\nTests-first force edge case discovery before implementing. Tests-after verify you remembered everything (you didn't).\n\n30 minutes of tests after ≠ TDD. You get coverage, lose proof tests work.\n\n## Common Rationalizations\n\n| Excuse                                  | Reality                                                                  |\n| --------------------------------------- | ------------------------------------------------------------------------ |\n| \"Too simple to test\"                    | Simple code breaks. Test takes 30 seconds.                               |\n| \"Controller's just wiring, skip a spec\" | Wiring has behavior — routing, params, response. Write the request spec. |\n| \"I'll run the test once at the end\"     | You won't know which change caused which failure. One change, one run.   |\n| \"I'll test after\"                       | Tests passing immediately prove nothing.                                 |\n| \"Tests after achieve same goals\"        | Tests-after = \"what does this do?\" Tests-first = \"what should this do?\"  |\n| \"Already manually tested\"               | Ad-hoc ≠ systematic. No record, can't re-run.                            |\n| \"Deleting X hours is wasteful\"          | Sunk cost fallacy. Keeping unverified code is technical debt.            |\n| \"Keep as reference, write tests first\"  | You'll adapt it. That's testing after. Delete means delete.              |\n| \"Need to explore first\"                 | Fine. Throw away exploration, start with TDD.                            |\n| \"Test hard = design unclear\"            | Listen to test.
