TestCafe v1.1.0 Released

This release introduces TypeScript 3.0 support and enhanced TypeScript definitions for client functions.

Enhancements

⚙ TypeScript 3 Support (#3401)

TypeScript test files can now use the new syntax features introduced in TypeScript 3.0 and TypeScript 3.3.

⚙ Enhanced TypeScript Definitions for Client Functions (#3431) by @vitalics

The updated type definitions allow the TypeScript compiler to determine client function’s return value type. Static typing now warns you when you call wrong methods for the return value.

const getFoo = ClientFunction(() => 42);
const foo    = await getFoo();
foo.match(/foo/);

Before v1.1.0, an error occurred during test execution:

$ testcafe chrome tests.ts
 Running tests in:
 - Chrome 72.0.3626 / Windows 10.0.0
 Fixture 1
 √ Test 1
 √ Test 2
 ...
 × Test N
   1) TypeError: foo.match is not a function

With v1.1.0, the TypeScript compiler throws an error before tests are started:

$ testcafe chrome tests.ts
  ERROR Cannot prepare tests due to an error.
  Error: TypeScript compilation failed.

  tests.ts (4, 2): Property 'match' does not exist on type 'number'.
