The monthly Partner Preview Security Bulletins list security vulnerabilities for device makers to fix on their devices. The Android Security Test Suite (STS) validates if security vulnerabilities are addressed on Android devices. STS is updated monthly with the Partner Preview Security Bulletin. STS helps partners to validate that:

• security patches are applied correctly
• corresponding security vulnerabilities are fixed
• device is not otherwise vulnerable

STS uses an automated testing harness with two major software components:

• The STS tradefed test harness runs on your desktop machine and manages test execution.
• Individual test cases are executed on the Device Under Test (DUT). The test cases are written in Java as JUnit tests and packaged as Android .apk files to run on the actual device target.

Types of test cases 测试用例类型

The STS includes the following types of test cases:

• Device Side Tests 设备端测试 are junit tests that are executed from the context of the DUT.
• Host Side Tests 主机端测试 are executed on the host machine, and allow the host to push binaries or other resources to the device.

Setting up STS STS环境设置 请参考CTS设置

STS is similar to Android's Compatibility Test Suite. To get started with STS, follow the CTS setup instructions.
