Overview

Concrete build orchestration file that defines the complete Gulp-based build, test, and release pipeline for the TestCafe project.

Description

The Gulpfile.js registers Gulp tasks and steps for: cleaning build artifacts, linting with ESLint, compiling TypeScript server scripts, bundling client scripts with Rollup, generating TypeScript definition files from Mustache templates, compiling LESS styles, running server/client/functional tests with Mocha across various browser configurations (local, headless, SauceLabs, mobile), and building/testing/publishing Docker images.

Usage

Use this file when contributing to the TestCafe project itself. Run tasks via gulp <taskname> to build, lint, test, or release TestCafe.

// Key Gulp tasks (registered via gulp.task / gulpStep)

// Build tasks
gulp.task('clean');             // Removes ./lib directory
gulp.task('lint');              // ESLint on src/**/*.js

// Compilation tasks
gulp.step('compile-client-scripts-bundle');  // Rollup client bundles
gulp.step('compile-ts');                     // TypeScript server compilation
gulp.step('generate-ts-defs');               // .d.ts from Mustache templates
gulp.step('styles');                         // LESS → CSS

// Test tasks
gulp.task('test-server');           // Server-side unit tests
