Dx Devops Test Failures Analyze

Analyze DevOps Center Test Failures

Parses a test failure or Code Analyzer violation payload, explains it in plain language, produces prioritized improvement suggestions, and — only on explicit user request — creates a tracked fix work item. Parts 1–2 are pure reasoning (no writes); Part 3 is an optional, confirmation-gated write.

Never expose raw JSON, stack traces, or internal Salesforce error codes to the user. Always translate to file name, method, line, and plain description.

Prerequisites

• Parts 1–2 (analysis): If the failure payload is already in context, no prerequisites are needed — this is pure reasoning. If you must fetch the payload yourself, run prerequisites (references/prerequisite-checks.md, Prereqs 1–4) and obtain the execution result via dx-devops-test-suite-run (its polling step).
• Part 3 (work item): Run Prerequisites 1–4. You also need a DevopsProjectId to file under and an OwnerId (assignee). See references/work-item-creation.md.

Part 1 — Classify and explain each failure

Determine the failure category, then for each failure extract and translate to plain language: offending file/class, method, line number, the rule or assertion violated, and a fix direction (without writing code). Group failures by category if more than one.

Output format:

textCopy code
Test failure summary:

<N> failure(s) found:

1. [<Category>] `<ClassName>.cls` — `<methodName>()` at line <N>
   What happened: <plain-language description>
   Rule violated: <ruleName or assertion description>
   Fix direction: <plain-language suggestion>

Full category/pattern tables and Code Analyzer rule translations: references/failure-categories.md and references/code-analyzer-violations.md.

Empty / no-data case: If the payload contains no failures or violations, report that clearly (e.g. "No failures found in the provided execution results.") and stop. Do NOT fabricate failures or suggestions.

Part 2 — Improvement suggestions

Run this after execution completes with failures, not on static source. For each failed test, reason over the failure message (the primary signal) to identify what the test is not handling, then produce a specific, actionable suggestion and a fix location (Test vs Production code). The full failure-pattern → suggestion mapping is in references/failure-categories.md.

textCopy code
Test improvement suggestions based on execution results:

`<testMethodName>()` — [Assertion Failure / Exception / etc.]
Failure: "<failure message>"
What this reveals: <plain-language explanation>
Suggestion: <specific, actionable recommendation>
Fix location: Test | Production code

Overall: <N> improvement(s) across <M> failed test(s).

Do not rewrite the test — only describe what needs to change and why. Fix location: Production code indicates a code defect exposed by a sound test (track separately, not a test-quality blocker). Fix location: Test indicates the test needs hardening (setup, assertions, edge cases).

Part 3 — Create a fix work item (optional, on request only)

Trigger only when the user wants to create a fix work item, log a remediation, or assign a failure to a developer. This is a write operation with a mandatory confirmation gate. Follow references/work-item-creation.md for inputs, the subject/assignee/project confirmation gate, the sf data create record --sobject WorkItem call, and error handling.

Use WorkItem (no namespace) — DevopsWorkItem is not a supported sObject in this org version.

If no DevopsProject exists in the org, report that the work item cannot be created until a project is set up — do NOT fabricate a project or proceed.
