Grok for Developers: Essentials — Testing Playbook

A focused playbook for testing with Grok. Learners attach a small library-fee module and its shaky tests to a grok.com chat, use Grok to diagnose a failing test and a date-dependent one, write unit and edge-case tests from the written policy, and break the code on purpose to prove the tests really catch bugs. They leave with a reusable prompt pattern for test work and the habit of checking every test themselves, by running it or by tracing it. About 45 minutes including the final.

What this course covers

The course runs across 3 topics, each one a short adaptive session rather than a recorded lecture. The tutor explains the idea, works an example, checks understanding, and adjusts the next step to the answer given.

Diagnosing failing and flaky tests with Grok — Attach the code and tests with the + button, paste the exact test output (or ask for a hand trace), and ask Grok whether the test or the code is wrong according to the written rules, with line numbers, before any fix. Learners fix a date-dependent test by passing in a fixed date instead of reading today's clock.
Writing unit and edge-case tests from the spec — Learners give Grok the policy and ask for tests at every boundary (grace period, cap, child card, early return, unknown item), each with an expected value worked out from the policy. They check expected values by hand and run or trace the tests themselves, because Grok has not run them.
Does the test really guard the behaviour? — Learners break one line on purpose and see which tests fail, spot tests that pass for a wide range of wrong values, and decide whether Grok's suggested change belongs in the test or in the code. In Grok Build the same loop runs on a branch, with Ask mode approving each test run.

Skills you build

Results are measured against named skills in the OneRange taxonomy of more than 10,000 skills, so a manager sees proficiency per skill rather than a completion tick.

Who it is for

Software developers. The material is pitched at beginner level, and takes roughly 45 minutes at a typical pace. Because every session adapts, someone who already knows a topic moves through it quickly instead of sitting through an explanation they do not need.

It sits in the Tool: Grok track of the Vero AI Catalog, and can be assigned to one person, a team, or the whole company.

How it is delivered and assessed

Delivery is conversational and interactive, including code lab, branching scenario exercises. There is no video to sit through and no slide deck to click past.

Understanding is checked with a lab assessment of 5 items, with a pass mark of 70%.

Administrators can copy this course into their own library and adapt it — edit the outline, change the duration, swap the assessment format, or ground it in internal documentation so answers cite the company's own source material.

Also in this track

Grok for Developers: Essentials — Code Review Playbook — A focused playbook for reviewing code with Grok. Learners attach a pull request written by a coding agent to a grok.com chat, ask for severity-ranked, line-referenced findings on correctness, security, risky edits and missing tests, then check each finding against the code instead of trusting it. They leave with a review prompt they can reuse and a short, defensible set of review comments. About 45 minutes including the final.
Grok for Developers: Essentials — Refactoring & Migration Playbook — A focused playbook for safe refactoring and migration with Grok. Learners pin a legacy reminder job's behaviour with characterisation tests, then use a grok.com chat to rename, extract a helper and move off a deprecated Python date function in small steps, checking the tests after each one. They leave with a step-by-step refactor pattern and a migration that changes nothing users see. About 45 minutes including the final.
Grok: Essentials — Research Playbook — A focused playbook for doing research in Grok. Learners run live searches across the web and X with citations, dig into their own files and connected sources, and check every claim - including deciding how much weight an X post deserves - so they leave with a research routine they can trust the same day. About 45 minutes including the final.
Grok for Developers: Essentials — Docs & Onboarding Playbook — A focused playbook for documentation and onboarding with Grok. Learners use a grok.com chat to explain an unfamiliar room-pricing module, catch the false claims in its outdated README, and write a corrected README, doc comments and a handoff note, checking every claim against the code by reading or running it. They leave with a documentation prompt pattern and the habit of verifying before they publish. About 45 minutes including the final.
Grok: Essentials — A practical introduction to getting real work done with Grok. Learners find their way around grok.com and the apps, write clear prompts, work with documents, spreadsheets and images, get live answers with sources from the web and X, and learn what not to share. By the end they can confidently use Grok for everyday writing, analysis and research.
Grok for Developers Pathway — Grok for developers from coding in chat to Grok Build in the terminal, agentic engineering, and guarded production integrations on the Grok API. Also includes 4 optional playbooks (Testing, Code Review, Refactoring & Migration, Docs & Onboarding) to take any time after Essentials; they don't count toward the certificate.

Frequently asked questions

How long does this course take?

It runs roughly 45 minutes at a typical pace. Because every session adapts, someone who already knows a topic moves through it quickly instead of sitting through an explanation they do not need.

How is it assigned to a team?

An administrator assigns it from the Vero dashboard to one person, a team, a department or the whole company, and sees progress and results per person and per skill.

Can we customise it with our own documents and terminology?

Yes. Administrators can copy this course into their own library and adapt it — edit the outline, change the duration, swap the assessment format, or ground it in internal documentation so answers cite the company's own source material.
