Each attempt gives you 20 random questions in 20 minutes from a 200-question bank covering type annotations and inference, any vs unknown, unions and literal types, enums and tuples, narrowing, typed functions, interfaces, utility types, classes and access modifiers, generics and typing Playwright page objects and fixtures. Submit to see your score, the correct answers and an explanation for every question.

What this mock test covers

The questions follow Module 3 of the free Playwright with TypeScript tutorial. Revise these lessons if a question catches you out:

Sample questions with answers

  • Q. What is TypeScript?
    Answer: A typed superset of JavaScript that compiles to plain JavaScript
    TypeScript adds static types to JavaScript. All valid JavaScript is valid TypeScript (with type checking on top).
  • Q. When does TypeScript catch type errors?
    Answer: At compile time (in the editor or with tsc), before the code runs
    Static checking finds mistakes like typos and wrong argument types while you write code.
  • Q. Which command type-checks a project without emitting JavaScript files?
    Answer: npx tsc –noEmit
    `tsc –noEmit` runs the compiler purely for type checking. It is useful because Playwright does not type-check tests.
  • Q. Which file configures the TypeScript compiler?
    Answer: tsconfig.json
    `tsconfig.json` holds compiler options such as `strict`, `target` and `module`.
  • Q. What does `"strict": true` in tsconfig.json enable?
    Answer: A family of stricter checks such as strictNullChecks and noImplicitAny
    Strict mode catches many more bugs and is recommended for test projects.
