Corporate training quote

Testing a web application by hand before every release burns an enormous amount of team time, and the bigger the system gets the less of it actually gets covered. The bugs users hit are usually in the paths nobody re-clicked. Playwright is Microsoft open-source automation tool that drives Chromium, Firefox and WebKit from a single codebase, with built-in auto-waiting that removes most of the mysterious flaky failures older tools were known for. This course takes

learners from zero to a working automated test suite: installation and project structure, writing tests and assertions, choosing locators that survive UI changes, handling forms and file uploads, reusing a saved login state, organizing code with the page object pattern, testing APIs alongside the UI, capturing screenshots, video and traces on failure, and finally running the whole suite automatically in CI/CD on every code change. (2 days, 6 hours per day, 12 hours in total, Beginner to Intermediate level.)

Objectives

Understand test automation and decide what is worth automating
Install Playwright and set up a test project the whole team can share
Write tests and assertions that verify what the business actually cares about
Choose locators that do not break when the UI changes
Handle waiting correctly so tests do not fail at random
Test forms, file uploads and logins that many tests depend on
Organize the suite with page objects and fixtures so it stays maintainable
Test APIs alongside the UI to seed data and verify results
Run the suite in CI/CD and read reports with screenshots and video on failure

Who this course is for

Web developers who want to cut the repeated manual testing before each release
QA engineers and software testers starting with test automation
Teams on older test tools who keep hitting unexplained flaky failures
DevOps engineers who want tests wired into the CI/CD pipeline
Small teams with no full-time QA who still want a test suite they can trust

Prerequisites

Basic understanding of how the web works and of HTML structure
Reasonable JavaScript or TypeScript skills (class examples use TypeScript)
Comfortable with the command line and installing tools on your own machine
Some Git experience makes the CI/CD section run more smoothly

Curriculum

Course Details

A 2-day course, 6 hours per day (12 hours in total), delivered as lectures with hands-on labs in every section. Beginner to Intermediate level. We provide a practice web application with forms, login, file upload and data tables so learners can cover every situation. Learners take home a lab guide, complete sample test code for every lab, and a working CI configuration. Playwright is open source and can be used in the organization at no licensing cost.

Day 1: Playwright Fundamentals and Writing Tests

Section 1: Test Automation Concepts

The cost of manual testing and the hidden cost as the system grows
Levels of testing: unit, integration and end-to-end, and what each is for
Deciding what belongs in automation and what should stay manual
What sets Playwright apart from earlier generations of test tools

Section 2: Installation and Project Structure

Installing Playwright and all three browsers in a single command
Test project structure and the configuration file you need to know
Running tests headed, headless and in UI mode
Lab: install Playwright and get the sample tests passing on all browsers

Section 3: Writing Tests and Assertions

Test file structure and grouping tests so they read clearly
Driving the browser: navigating, clicking, typing, selecting and scrolling
Writing assertions for text, state and elements on the page
Lab: write your first end-to-end test against the practice application

Section 4: Locators and Selecting Elements

Choosing locators that survive future UI changes
Selecting by text, role and label instead of depending on HTML structure
Handling repeated lists, tables and deeply nested elements
Lab: rework the locators in an existing test so a layout change no longer breaks it

Section 5: Waiting and Flaky Tests

Playwright auto-waiting and why you should not add fixed delays
Waiting for specific conditions: data loading, navigation and API calls
Why a test passes sometimes and fails others, and how to trace the cause systematically
Lab: fix an intermittently failing test so it passes reliably every run

Day 2: Structure, APIs and CI/CD

Section 6: Forms, Files and Login

Filling every kind of form control: text fields, selects and date pickers
Uploading and downloading files and verifying the result
Saving login state so tests do not have to log in again every time
Lab: write tests that log in once and reuse that state everywhere else

Section 7: Page Objects and Code Organization

The page object pattern and separating UI detail from test logic
Using fixtures to prepare the environment and data before a test runs
Separating test data from code so one test can run against many data sets
Lab: refactor your tests into maintainable page objects

Section 8: Testing APIs Alongside the UI

Calling APIs directly from Playwright to seed data before a UI test
Verifying backend results after acting through the interface
Intercepting and mocking API responses to test hard-to-produce cases
Lab: write a test that seeds data over the API then verifies it in the UI

Section 9: Reporting and Debugging

Reading the test report and seeing exactly which step failed
Capturing screenshots, video and traces automatically on failure
Using Trace Viewer to replay every step of a failed test
Using Codegen to draft tests, and what to watch out for in the generated code

Section 10: Running in CI/CD

Running the suite automatically on every code change or pull request
Running tests in parallel and sharding across machines for speed
Handling secrets and configuration across dev and staging environments
Lab: configure the suite to run automatically in CI and publish its report

Section 11: Capstone and Real-World Use

Capstone: build a suite covering the critical paths of one web application end to end
Deciding which paths are worth automating first
Keeping the suite from becoming a maintenance burden over time
Workshop: present your suite and review its structure together
