Testing
Electron applications combine Node.js and Chromium into a single runtime, making them powerful but uniquely challenging to test. Unlike pure web apps or pure Node.js services, Electron apps have two processes—main and renderer—that communicate via IPC. Jest is the go-to testing framework for the Node.
Testing
Electron apps run web content in a desktop shell with access to Node.js APIs. This combination is powerful — and dangerous. Security vulnerabilities in Electron apps can lead to remote code execution (RCE), making security testing not optional but critical. This guide covers automated security testing for Electron applications: testing
Testing
Playwright has first-class support for Electron application testing since v1.9. Unlike Spectron (deprecated) or older Electron testing approaches, Playwright connects to Electron directly — giving you access to both the renderer process (web content) and the main process (Node.js environment) in a single test. This guide covers Electron
Testing
Desktop apps must work on Linux, macOS, and Windows — and each platform has different rendering engines, file system behaviors, system APIs, and distribution formats. A CI/CD pipeline that only tests on one platform misses platform-specific bugs. This guide covers building cross-platform CI/CD testing pipelines for desktop
Testing
Electron applications present a unique testing challenge: they're web apps running in a desktop shell, combining Chromium's rendering engine with Node.js. Playwright, Microsoft's browser automation library, has native Electron support that lets you drive Electron apps the same way you'd drive
Testing
Electron E2E testing with Playwright tests the full application, but unit tests with Jest run in milliseconds and catch business logic bugs during development. The challenge is that Electron's main process and renderer both have APIs that don't exist in Node.js or jsdom test environments.
