 ## Workflow
 
-### Step 1: Plan Test Scenarios
+### Step 1: Map User Journeys to Test Scenarios
 
-Identify critical business processes (e.g., Lead → Opportunity → Quote → Order). Map user journeys to testable flows and prioritize by risk:
+Before writing any test code, map critical business processes to testable scenarios. Use this template:
 
-- HIGH: financial, compliance, data integrity across objects
-- MEDIUM: standard CRUD with automation (triggers, flows)
-- LOW: UI polish, optional fields
+```
+Journey: [Business Process Name]
+  Trigger: [What starts the process — user action, API call, scheduled job]
+  Objects: [All SObjects touched in sequence]
+  Automation: [Triggers, Flows, Process Builders, Queueables involved]
+  Integrations: [External callouts, Platform Events, CDC]
+  Exit: [Expected end state — records, notifications, events]
+```
+
+**Prioritize by risk:**
+
+| Priority | Criteria | Examples |
+|----------|----------|---------|
+| **CRITICAL** | Financial, compliance, data integrity across 3+ objects | Order → Invoice → Payment, Lead conversion with territory assignment |
+| **HIGH** | Core CRUD with multi-step automation chains | Opportunity stage progression with approval process |
+| **MEDIUM** | Standard automation with single trigger/flow | Case escalation, Task auto-creation |
+| **LOW** | Read-only operations, reporting, optional fields | Dashboard refresh, field history tracking |
+
+For each scenario, define these test dimensions:
+
+| Dimension | What to Test |
+|-----------|-------------|
+| Happy path | Normal flow with valid data |
+| Bulk (200 records) | Trigger context maximum — catches non-bulkified code |
+| Bulk (10K records) | Batch/async context — catches governor limit issues at scale |
+| Null / empty inputs | Missing required relationships, blank fields |
+| Permission boundaries | Standard User, Community User, Admin — `System.runAs()` |
+| Cross-object integrity | Parent-child cascades, rollup summaries, lookup filters |
+| Async chain completion | Queueable → Queueable chains, Batch → Batch sequences |
+| Platform Event delivery | Publish → Subscribe → Side-effect verification |
+| Error recovery | DML failures, callout timeouts, partial success scenarios |
+
+### Step 2: Create Test Data Architecture
+
+Design a `TestDataFactory` that builds the complete object hierarchy for your E2E scenarios. This is the foundation — poor test data is the #1 cause of flaky E2E tests.
+
+**Principles:**
+- Build data top-down: Account → Contact → Opportunity → OpportunityLineItem
+- Use `@TestSetup` for the shared base hierarchy (runs once per test class)
+- Use `TestDataFactory` methods for scenario-specific variations
+- Never use `SeeAllData=true`
+- Never hardcode record IDs — query by Name or ExternalId
+- Create test users in `@TestSetup` with appropriate profiles/permission sets
 
-For each scenario, define: happy path, edge cases (null inputs, 0 records, 200-record bulk), and governor limit boundaries.
+**Data volume targets:**
 
-### Step 2: Create Apex E2E Tests
+| Context | Volume | Why |
+|---------|--------|-----|
+| Unit test | 1-5 records | Fast, isolated |
+| E2E trigger test | 200 records | Trigger context limit |
+| E2E batch test | 2,000+ records | Batch chunk processing |
+| E2E bulk load | 10,000+ records | Governor limit stress test (use Batch Apex in test) |
 
-Use `@TestSetup` for shared data, `TestDataFactory` for all record creation, and `Test.startTest()`/`Test.stopTest()` to reset governor limits around the code under test.
+### Step 3: Create Apex E2E Tests
+
+Use `Test.startTest()`/`Test.stopTest()` to reset governor limits around the code under test. This is critical for E2E tests where setup consumes significant limits.
+
+**Key patterns for E2E:**
 
-Key patterns:
 - `@TestSetup` — create the full data hierarchy once per class
 - `HttpCalloutMock` / `Test.setMock()` — mock all external callouts
 - `Test.getEventBus().deliver()` — force synchronous Platform Event delivery
 - `System.runAs()` — test permission-sensitive operations
+- `Limits.getQueries()` / `Limits.getDmlStatements()` — assert governor limit consumption
 
-See skill `sf-apex-testing` for full TestDataFactory and governor limit patterns.
+See skill `sf-e2e-testing` for complete code examples covering:
+- Full sales cycle (Lead → Opportunity → Quote → Order)
+- Flow integration testing (Record-Triggered Flows with E2E verification)
+- Platform Event publish → subscribe → side-effect verification
+- Async job chains (Queueable → Queueable completion)
+- Multi-user permission testing with `System.runAs()`
+- Performance assertions (SOQL count, DML count within bounds)
 
-### Step 3: Create LWC Integration Tests
+### Step 4: Create LWC Integration Tests
 
-Use Jest with `@salesforce/apex` mocks. For imperative Apex calls use `jest.fn()` + `mockResolvedValue`. For `@wire`-decorated properties use `createApexTestWireAdapter` from `@salesforce/sfdx-lwc-jest`.
+Use Jest with `@salesforce/apex` mocks for LWC integration testing. E2E LWC tests differ from unit tests in that they exercise multi-component interaction and full data flow.
 
-Always clean the DOM in `afterEach` and call `jest.clearAllMocks()`. See skill `sf-lwc-testing` for full wire adapter patterns.
+**E2E LWC test patterns:**
+- Parent-child component communication via events
+- Multiple wire adapters loading in sequence
+- Error state propagation (Apex throws → component shows error)
+- Navigation after successful operations (`NavigationMixin`)
+- Toast notification assertions after DML operations
 
-Run LWC tests:
+Always clean the DOM in `afterEach` and call `jest.clearAllMocks()`. See skill `sf-lwc-testing` for complete wire adapter and event testing patterns.

+# Run LWC tests with coverage

-Run in scratch org for isolation. For CI, run multiple times at different hours to detect flakiness caused by async platform-side timing. Target: code coverage > 85% (75% minimum), all critical-path tests passing, zero flaky tests.
+**Coverage targets:**
 
-### Step 5: Handle Flaky Tests
+| Level | Target | When |
+|-------|--------|------|
+| Minimum | 75% | Salesforce deployment requirement |
+| Standard | 85% | Production-ready, covers major paths |
+| Comprehensive | 95%+ | Critical financial/compliance code |
+
+### Step 6: Handle Flaky Tests
+
+Flaky tests erode confidence in the test suite. Diagnose systematically:
+
+| Root Cause | Symptom | Fix |
+|------------|---------|-----|
+| Async timing | Test passes sometimes, fails on platform lag | Ensure `Test.stopTest()` after enqueue; use `Test.getEventBus().deliver()` |
+| Order-dependent queries | Results vary across runs | Add explicit `ORDER BY` in test SOQL |
+| Sharing rule access | Works for admin, fails for test user | Use `System.runAs()` with appropriate profile |
+| Platform Events | Subscriber doesn't fire | Use `Test.getEventBus().deliver()` for synchronous delivery |
+| Mixed DML | Inserting User and business object in same transaction | Separate into different `System.runAs()` blocks |
+| Timezone sensitivity | Date comparisons fail in different orgs | Use `Date.today()` not hardcoded dates; use UTC for DateTime |
+| SOQL row ordering | Query returns different row first | Always `ORDER BY` and `LIMIT` in test queries |
+| Parallel test execution | Tests interfere with shared data | Use unique identifiers (timestamp + test name) in test data |
+
+**Flaky test remediation process:**
+1. Run the failing test 5 times in isolation — if it passes consistently, the issue is test interference
+2. Run with `--synchronous` flag to disable parallel execution
+3. Check `ApexTestResult` for governor limit proximity (>80% of any limit = fragile)
+4. Add `System.debug` checkpoints at failure points and review debug logs
+
+### Step 7: CI Integration
+
+For CI pipelines, structure E2E tests to run in stages:
+
+```
+Stage 1: LWC Jest (fast, local, no org needed)
+  └── npm run test:unit -- --coverage
+
+Stage 2: Apex Unit Tests (focused, fast)
+  └── sf apex run test --class-names "UnitTest1,UnitTest2" --wait 10
+
+Stage 3: Apex E2E Tests (slower, full integration)
+  └── sf apex run test --test-level RunLocalTests --wait 15
+
+Stage 4: Deploy Validation (pre-production gate)
+  └── sf project deploy validate --test-level RunLocalTests --target-org staging
+```
+
+For large orgs, use `RunRelevantTests` (API 66.0+) to run only tests affected by the changed metadata.
+
+## E2E Test Organization
+
+Name E2E test classes with the `E2E` suffix to distinguish from unit tests:
+
+```
+force-app/test/default/classes/
+  ├── unit/
+  │   ├── AccountServiceTest.cls
+  │   └── ContactTriggerHandlerTest.cls
+  └── e2e/
+      ├── LeadConversionE2ETest.cls
+      ├── OrderFulfillmentE2ETest.cls
+      └── CaseEscalationE2ETest.cls
+```
 
-| Root Cause | Fix |
-|------------|-----|
-| Async timing (Queueable/Batch) | Ensure `Test.stopTest()` is called after enqueue |
-| Order-dependent queries | Add explicit `ORDER BY` in test SOQL |
-| Sharing rule access | Use `System.runAs()` with appropriate user profile |
-| Platform Events | Use `Test.getEventBus().deliver()` for synchronous delivery |
+Each E2E test class should:
+- Test one complete business workflow end-to-end
+- Have a `@TestSetup` method that builds the full data hierarchy
+- Include at minimum: happy path, bulk (200), and error/negative test methods
+- Assert on downstream side-effects (Tasks created, Events published, child records updated)
 
 ## Escalation
 
 Stop and ask the human before:
 - Creating a new scratch org (may consume org limits or require specific definition files)
 - Running any operation that modifies or deletes real test data in a non-scratch org
 - Modifying an existing test class that already has passing tests — confirm intended scope first
+- Running tests against a production org (even read-only tests consume API limits)
 
 Never proceed past an escalation point autonomously.
