# sf-testing: Salesforce Test Execution & Coverage Analysis

Use this skill when the user needs **Apex test execution and failure analysis**: running tests, checking coverage, interpreting failures, improving coverage, and managing a disciplined test-fix loop for Salesforce code.

## When This Skill Owns the Task

Use `sf-testing` when the work involves:
- `sf apex run test` workflows
- Apex unit-test failures
- code coverage analysis
- identifying uncovered lines and missing test scenarios
- structured test-fix loops for Apex code

Delegate elsewhere when the user is:
- writing or refactoring production Apex → [sf-apex](../sf-apex/SKILL.md)
- testing Agentforce agents → [sf-ai-agentforce-testing](../sf-ai-agentforce-testing/SKILL.md)
- testing LWC with Jest → [sf-lwc](../sf-lwc/SKILL.md)

---

## Required Context to Gather First

Ask for or infer:
- target org alias
- desired test scope: single class, specific methods, suite, or local tests
- coverage threshold expectation
- whether the user wants diagnosis only or a test-fix loop
- whether related test data factories already exist

---

## Recommended Workflow

### 1. Discover test scope
Identify:
- existing test classes
- target production classes
- test data factories / setup helpers

### 2. Run the smallest useful test set first
Start narrow when debugging a failure; widen only after the fix is stable.

### 3. Analyze results
Focus on:
- failing methods
- exception types and stack traces
- uncovered lines / weak coverage areas
- whether failures indicate bad test data, brittle assertions, or broken production logic

### 4. Run a disciplined fix loop
When the issue is code or test quality:
- delegate code fixes to [sf-apex](../sf-apex/SKILL.md) when needed
- add or improve tests
- rerun focused tests before broader regression

### 5. Improve coverage intentionally
Cover:
- positive path
- negative / exception path
- bulk path (251+ records where appropriate)
- callout or async path when relevant

---

## High-Signal Rules

- default to `SeeAllData=false`
- every test should assert meaningful outcomes
- test bulk behavior, not just single-record happy paths
- use factories / `@TestSetup` when they improve clarity and speed
- pair `Test.startTest()` with `Test.stopTest()` when async behavior matters
- do not hide flaky org dependencies inside tests

---

## Output Format

When finishing, report in this order:
1. **What tests were run**
2. **Pass/fail summary**
3. **Coverage result**
4. **Root-cause findings**
5. **Fix or next-run recommendation**

Suggested shape:

```text
Test run: <scope>
Org: <alias>
Result: <passed / partial / failed>
Coverage: <percent / key classes>
Issues: <highest-signal failures>
Next step: <fix class, add test, rerun scope, or widen regression>
```

## Cross-Skill Integration

| Need | Delegate to | Reason |
|---|---|---|
| fix production code or author tests | [sf-apex](../sf-apex/SKILL.md) | code generation and repair |
| create bulk / edge-case data | [sf-data](../sf-data/SKILL.md) | realistic test datasets |
| deploy updated tests | [sf-deploy](../sf-deploy/SKILL.md) | rollout |
| inspect detailed runtime logs | [sf-debug](../sf-debug/SKILL.md) | deeper failure analysis |

## Score Guide

| Score | Meaning |
|---|---|
| 108+ | strong production-grade test confidence |
| 96–107 | good test suite with minor gaps |
| 84–95 | acceptable but strengthen coverage / assertions |
| < 84 | below standard; revise before relying on it |
