Software testing and QA
Test so you know what actually works.
1:1 online lessons in manual testing, API testing, Playwright and BDD — in Polish
Who it’s for For beginner testers, manual testers moving into automation and developers who want to write better tests.
What we work on You write the test scenarios and tests yourself. I help you decide what to test, in what order and how to keep it maintainable.
Topics you can bring
From the ground up
- Test cases and bug reports that someone will actually read
- API testing: Postman, status codes, contracts
- Exploratory testing: how to find what nobody anticipated
- Your first Playwright test
More advanced
- Playwright: page objects, fixtures, stable selectors
- BDD and Gherkin: acceptance criteria you can automate
- Unit and integration tests on the developer side
- Tests in CI: parallelization, reports, flaky tests
Example sessions
- Scenario A
From a test scenario to an automated test
We take one manual scenario from your work and turn it into a Playwright test. You do the writing, I give pointers.
- Scenario B
A test strategy for a small project
We work out what’s riskiest in your project, where it’s worth investing time and where a manual test is enough.
- Scenario C
Flaky tests
Got tests that pass one run and fail the next? We track down the cause together and fix them so the problem doesn’t come back.
Example outcomeTest scenarios and tests you wrote yourself
How we work
We learn testing on a real application. If you don’t have one of your own, we’ll pick a public practice app or a small project that I’ll prepare.
I care that you understand why a test is written the way it is. A good test describes behavior, not implementation, and doesn’t break with every UI change.
I also bring in the perspective of the developer and of the person responsible for the product, because testing is part of the conversation about risk, not a separate stage at the end.
Sessions are held in Polish.
What I don’t do
- I don’t do your testing for you, and I don’t write take-home interview tasks.
- I don’t prepare you for specific certifications.
