What is the difference between native, hybrid, and mobile web apps from a testing perspective?

Short answer

Short answer: Native apps are platform-specific binaries (Swift/Kotlin) with full device API access. Hybrid apps wrap a WebView in a native shell (Ionic/Cordova). Mobile web apps run entirely in the browser. Each requires different tooling and has different test characteristics.

Detail

Native apps are compiled for a specific platform — Swift/Objective-C on iOS, Kotlin/Java on Android. They have direct access to all device hardware and are tested with UIAutomator2 (Android) or XCUITest (iOS) via Appium, or with the native frameworks directly. They behave consistently within their platform but require separate codebases and separate test suites.

Hybrid apps embed a WebView inside a native container. The UI is HTML/CSS/JS, but native features (camera, push notifications) are accessed via a bridge. Appium can control the native shell, but testing content inside the WebView requires switching context (driver.context('WEBVIEW_...')). This context switching is one of the most common sources of test brittleness in hybrid app automation.

Mobile web apps run in the mobile browser (Safari on iOS, Chrome on Android) and are tested with standard WebDriver tools. They have the fewest device-API capabilities but the simplest test setup — your existing Playwright or Selenium suite can target mobile browsers with the right device emulation or real device browser session.

// WHAT INTERVIEWERS LOOK FOR

Clear definition of each type, with specific test tooling implications — particularly the WebView context switch required for hybrid apps.

// COMMON PITFALL

Confusing hybrid apps with Progressive Web Apps (PWAs). PWAs are mobile web apps with service worker capabilities — they run in the browser, not in a native WebView shell.
