How it works

7 marathon days, and each one brings you:

01

Your own pace

The theory and practice open right away — you go through each day at your own pace.

02

Theory of the day

One clear piece of material, no fluff.

03

Practice

A task on a real case, followed by a worked solution.

04

Star rule of the day

One takeaway that stays with you.

Marathons

Pick your week

Three topics, one format: 7 days of theory, practice and a worked solution.

Basic API knowledge

API marathon: 7 days under the hood

Inna Osinna

7 everyday actions — and each day you see what the backend does with them.

7-day programme

  1. Day 1
    Login. What is inside the token?
    JWT under the hood

Bonus: Test scenarios for the refresh token.

Result

At least 10 bugs found and new test scenarios. A level above most junior API QA candidates.

Junior / Middle

Test design in practice: 7 days challenge

Inna Osinna and Alina Pasevina

One test design technique a day — with practice and a worked solution.

7-day programme

  1. Day 1
    Test analysis
    Test analysis canvas: what the system is, who uses it, what is critical

Bonus: Test design artifact templates.

Result

Your own set of artifacts (Test analysis canvas, tables, state transition diagrams) and the ability to explain why you test exactly this.

Claude Skill: automating requirements analysis

Inna Osinna

From a checklist in your head to your own skill that reviews requirements.

7-day programme

  1. Day 1
    The requirement is “clear”. But is it testable?
    7 requirement quality criteria

Result

A working skill for requirements review, dozens of issues found in requirements and your first AI artifact in your portfolio (published on GitHub).

Who it is for

Sound familiar?

If even one of these is about you, a marathon is for you.

You only see the UI — half the picture

Postman is open, DevTools too, but where to look and what to look for is unclear.

Your test design lives “in your head”

You write tests, but explaining why these ones and why they are enough is hard.

Requirements arrive “verbally”

You review requirements by eye, and AI answers differently every time — so there is no trust.

Questions

FAQ

How do I get access after paying?

Right after payment WayForPay sends an email to the address you enter at checkout, with a link to the marathon in Telegram. If there is no email, check your spam folder or message @innaosinna on Telegram with a screenshot of the payment.

What do I need in advance?

It depends on the marathon: each description above has a “You will need” list. For API — Chrome, Postman desktop and Google Sheets; for Claude Skill — a Claude account (the free plan is enough) and Google Docs.

How much time a day?

About 30 minutes: a short intro, the theory of the day and a practical task.

Can my company pay, or can I get documents?

If you need help with a company payment, message @innaosinna on Telegram. We will discuss the details and prepare the documents needed for the payment.
