# TDD Test Implementation for [Component/Feature Name]

**When to use this template:** Use this when you realize you didn't follow TDD properly, notice inadequate test coverage for a specific feature, or need to pause development to implement better tests for the code you're currently working on.

**When NOT to use this template:** Don't use this for comprehensive test audits, large-scale testing initiatives, or tests that are already part of your current TDD workflow. This is for targeted, immediate test improvements.

## Overview & Context for [Component/Feature]

* **Component/Feature:** [e.g., User Authentication Module or Payment Processing Service]
* **Related Work:** [e.g., Link to Feature Card or Current Sprint Task]
* **Motivation:** [e.g., Noticed edge cases not covered or Realized TDD was skipped during initial implementation]

**Required Checks:**
* [ ] Component or feature being tested is identified above.
* [ ] Related work or original card is linked.
* [ ] Clear motivation for pausing to add tests is documented.

---

## Initial Assessment

> Use this space to capture your immediate thoughts about the testing gap. What made you realize tests were needed? What specific scenarios are you worried about?

* [e.g., Concern: "The login function doesn't test invalid credentials"]
* [e.g., Gap noticed: "No tests for null inputs in parser"]
* [e.g., Realization: "I wrote the whole thing without a single failing test first"]
* [e.g., Risk: "This handles user data but has no validation tests"]

### Current Test Coverage Analysis

| Test Type | Current Coverage | Gap Identified | Priority |
| :--- | :--- | :--- | :---: |
| **Unit Tests** | [e.g., 0% or 45% or Link to coverage report] | [e.g., No tests for error cases] | [P0/P1/P2] |
| **Integration Tests** | [e.g., None or Partial] | [e.g., No tests for database failures] | [P0/P1/P2] |
| **Edge Cases** | [e.g., None] | [e.g., No tests for boundary values] | [P0/P1/P2] |

## TDD Implementation Workflow

| Step | Status/Details | Universal Check |
| :---: | :--- | :---: |
| **1. Write Failing Tests** | [Link to test file or commit] | - [ ] Failing tests are written and committed. |
| **2. Implement Code** | [Summary of changes or Link to implementation] | - [ ] Minimal code to make tests pass is implemented. |
| **3. Verify Tests Pass** | [Test run results or Link to CI run] | - [ ] All new tests are passing. |
| **4. Refactor** | [Refactoring notes or N/A] | - [ ] Code is refactored for quality (or N/A is documented). |
| **5. Regression Check** | [Link to full test suite run] | - [ ] Full test suite passes with no regressions. |

### Test Cases Defined

Document each test case you're implementing below:

| Test Case # | Description | Input | Expected Output | Status |
| :---: | :--- | :--- | :--- | :---: |
| **1** | [e.g., Test invalid email format] | [e.g., "not-an-email"] | [e.g., ValidationError] | [Not Started/In Progress/Complete] |
| **2** | [e.g., Test null password] | [e.g., password=None] | [e.g., ValueError] | [Not Started/In Progress/Complete] |
| **3** | [e.g., Test successful login] | [e.g., valid credentials] | [e.g., 200 OK + token] | [Not Started/In Progress/Complete] |
| **4** | [Test case...] | [Input...] | [Expected...] | [Status...] |

#### Test Implementation Notes (Optional)

> [Paste test code snippets, link to test files, or document testing approach here.]

```python
# Example test structure
def test_invalid_email_format():
    # Arrange
    # Act
    # Assert
    pass
```

## Test Execution & Verification

| Iteration # | Test Batch | Action Taken | Outcome |
| :---: | :--- | :--- | :--- |
| **1** | [e.g., Tests 1-3 or Initial batch] | [e.g., Ran pytest on test_auth.py] | [e.g., 2 passing, 1 failing (expected)] |
| **2** | [e.g., After implementation] | [e.g., Re-ran test suite] | [e.g., All passing] |
| **3** | [e.g., Full regression] | [e.g., Ran entire test suite] | [e.g., No regressions detected] |

---
#### Iteration 1: [Initial Test Run]

**Test Batch:** [e.g., Test cases 1-3: Input validation tests]

**Action Taken:** [e.g., Executed pytest with new test file test_auth_validation.py]

**Outcome:** [e.g., All 3 tests failed as expected - no validation logic exists yet. Ready for implementation phase.]

---
#### Iteration 2: [Post-Implementation Verification]

**Test Batch:** [e.g., Same test cases after implementing validation]

**Action Taken:** [e.g., Implemented validation logic, re-ran tests]

**Outcome:** [e.g., All tests passing. Code coverage increased from 45% to 78%.]

*(Copy and paste the 'Iteration N' block above for each subsequent test cycle.)*

## Coverage Verification

| Metric | Before | After | Target Met? |
| :--- | :---: | :---: | :---: |
| **Line Coverage** | [e.g., 45%] | [e.g., 78%] | [Y/N] |
| **Branch Coverage** | [e.g., 30%] | [e.g., 65%] | [Y/N] |
| **Test Count** | [e.g., 5] | [e.g., 12] | [Y/N] |

* [ ] Coverage report generated and reviewed.
* [ ] All critical paths are now tested.
* [ ] Edge cases identified in assessment are covered.

## Completion & Follow-up

| Task | Detail/Link |
| :--- | :--- |
| **Code Review** | [Link to PR or Self-review notes] |
| **CI/CD Verification** | [Link to successful CI run] |
| **Coverage Report** | [Link to coverage report or Summary] |

### Follow-up & Lessons Learned

| Topic | Status / Action Required |
| :--- | :--- |
| **Similar Gaps Elsewhere?** | [e.g., Yes - Need to check payment module next or No] |
| **Process Improvement** | [e.g., Added pre-commit hook to check coverage or Updated team TDD guidelines] |
| **Future Refactoring** | [e.g., Created ticket TECH-456 to refactor for better testability or N/A] |
| **Documentation Updates** | [e.g., Updated README with testing requirements or N/A] |

### Completion Checklist

* [ ] All test cases defined in the table are implemented.
* [ ] All tests are passing.
* [ ] Code coverage meets or exceeds target for this component.
* [ ] Full regression suite passes with no failures.
* [ ] Code is refactored and clean.
* [ ] Changes are committed and pushed.
* [ ] Follow-up actions are documented or tickets created.
* [ ] Original work (feature/bug) can be resumed with confidence.
