JavaScript/TypeScript for SDET

JavaScript/TypeScript for SDET turns a specialised topic into a coherent, job-relevant workflow. Participants learn to develop reliable test code in JavaScript and TypeScript while understanding asynchronous execution, typing, modules and modern tooling, using node, npm and modern javascript project setup to establish the foundation and values, functions, objects and collections to deepen the work. Participants model data, write functions and classes, use promises and async/await, handle errors, configure TypeScript, test utilities and organise an npm-based project suitable for Playwright or API automation. The final part connects modules, scope and dependency boundaries with reporting, review and improvement so that the result can support an actual quality decision. The course targets the language features that most affect automation readability, timing and maintainability.
