Android Testing in Chromium

Concepts

Native Unit Tests: Normal Chromium unit tests based on the gtest framework. Tests for native code.
Java Unit Tests: JUnit tests that run on the host machine using Robolectric to emulate Android APIs.
Instrumentation Tests: JUnit tests that run on Android devices (or emulators).
- Unit Instrumentation Tests: Instrumentation tests that test an individual feature. They do not require starting up ContentShell (or Chrome browser). These use BaseActivityTestRule or BlankUiTestActivityTestCase based on BaseActivityTestRule.
- Integration Instrumentation Tests: Instrumentation tests that bring up ContentShell (or Chrome browser) to test a certain feature in the end-to-end flow. These typically use more specialized test rules such as ContentShellActivityTestRule or ChromeActivityTestRule.
