The week-by-week path from writing test cases to building the framework that runs them — Python, Selenium and Playwright, API automation, CI, and a real interview question bank at the top.
You already find the bugs other people miss. What you don't have is a route from there to a QA Automation / SDET role — one that assumes your testing instincts are sharp and rebuilds the engineering half from zero.
A repeatable 6-step method for reading a problem and writing the code, so it stops feeling like guesswork.
Selenium, Playwright, requests and pytest — suites that still make sense at 300 tests.
Page objects, fixtures, data-driven design, CI pipelines. The part that separates an SDET from a scripter.
Speed up test design and review with AI without handing it your judgment.
One goal, a skills checklist, and checkpoints that tell you when you're actually ready to move up.
Paste the module's tutor prompt into your AI. It questions and hand-traces with you instead of answering for you.
Auto-graded interview challenges, run in the browser. Green checks mean it stuck.
Python runs locally, so there's no server to wait on. Ten more languages in a sandbox, plus graded challenges.
Open the Code Lab →Write a locator against a live page and watch it highlight as you type. Graded challenges included.
Open the Locator Lab →ATS resume checker, boundary-value generator, QA metrics, bug-report builder. All of it stays in your browser.
Open the Tools →A free, self-paced roadmap from manual testing to a QA Automation / SDET role over 24 weeks. Every module has a goal, in-app lessons with worked examples and drills, and checkpoints — so you always know what's next.
Manual QA testers and junior automation engineers who are already sharp at finding bugs and now want the engineering half: Python, UI and API automation, framework design, and the interview.
Yes. Roadmap, lessons, Code Lab and tools — no paywall, no premium tier, no credit card. An account exists only to save your progress across devices.
No. The first modules rebuild programming logic in Python from zero, assuming only your testing experience. Automation, frameworks and architecture come after, with no gaps skipped.
It's built as a 24-week climb at a part-time pace, but nothing is timed. Your progress is saved, so you can stop for a month and pick up where you left off.
Every module teaches in the app — lessons, worked examples, drills. The AI-tutor prompt is optional on top: it asks questions and hand-traces with you rather than handing over answers.
That's the point of the last module: a bank of the questions QA Automation / SDET loops actually ask, with model answers you can rehearse out loud.
Start on rung one. It's free, and your progress saves from the first checkbox.
Logic building isn't a chapter you read — it's a discipline you repeat. Apply these six steps to every problem in the roadmap until they're automatic. The hand-trace in step 6 is where most of the learning happens.
QALadder is an open, community roadmap that turns manual testers and junior automation engineers into senior QA Automation / SDET engineers. It's a structured 24-week climb — Python and logic, UI and API automation, framework architecture, AI-augmented QA, and a real interview bank — taught with in-app lessons, browser-based practice, and progress that follows you. Nothing is paywalled and nothing is sold on.
New to problem-solving under pressure? Start with our 6-Step Problem-Solving Method → — the repeatable approach every roadmap problem uses.
Ten modules from Python foundations to lead-level strategy — each with a clear goal, a skills checklist, and checkpoints that tell you when you're ready to move on.
Every module teaches right here: plain-English explanations, QA-flavored code examples, and practice drills — no need to leave the app.
Solve auto-graded interview challenges in the browser. Python runs locally with no server; ten more languages run in a secure sandbox.
Seven testing-specific utilities — ATS resume checker, boundary-value generator, metrics calculator and more — all running privately in your browser.
The most-asked QA automation / SDET questions with model answers, so you rehearse the structure of a strong answer — not generic trivia.
Each module ships an optional prompt that turns any AI into a Socratic coach: it questions and hand-traces with you instead of handing over answers.
You can browse the whole roadmap, the lessons, the Code Lab, and the tools without one. A free account only exists to save your progress to the server so it follows you across devices.
Yes. Your progress is visible only to you. We store your name, email, a hashed password, and your checkbox states — nothing else. Your resume and code stay in your browser and are never uploaded.
There's no catch: no paywall, no premium tier, no ads, and we don't sell data. QALadder is built by testers for the QA community.
The site admin, through an in-app editor. Published edits appear for everyone at once, so the roadmap and interview bank stay current.
Absolutely. Many people use it to shore up Python and automation fundamentals or to prep gradually. It's self-paced — go as fast or slow as you like, and your progress waits for you.
Work the 6-Step Method, drill the concept in the Code Lab, and use the module's AI-tutor prompt to get coached through it. Move on only when the checkpoints are true.
Your progress lives in your account and syncs across every device you sign in on. Wiping it clears every ticked topic, checkpoint, and solved challenge from your account and this device — this can't be undone.
Pick the first rung. It's free, and nothing about it expires.
Free forever. Your progress saves automatically.
