Security Test Suite
Effective in 2026, to align with our trunk stable development model and ensure platform stability for the ecosystem, we will publish source code to AOSP in Q2 and Q4. For building and contributing to AOSP, use android-latest-release. The android-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP.

CTS 17 release notes
Stay organized with collections
Save and categorize content based on your preferences.
This page includes the key CTS changes introduced in CTS 17 R1.
Infrastructure improvements
Test result aggregation and reporting
The CTS-V reporting structure (including CameraITS) has been refactored to
support granular subtest results. This enhancement enables parallel execution
of subtests to reduce total runtime, and focused reruns of failed subtests
rather than the full module.
Token sharding
Fixed an issue with the enable-token-sharding feature, which sometimes fails
to recognize samples with SIM cards, causing tests to run incorrectly.
Efficiency improvements
Biometrics test optimization
The biometric test suite in CTS-V combines multiple time-based key tests,
reducing the number of authentication prompts from 120 to 72.
Connectivity and ranging modernization
The manual Presence test, which requires a standardized 1 m device setup
for accurate validation, has been replaced by a fully automated Ranging module
(Ranging test).
Wi-Fi test modernization
Updates to the Wi-Fi test suite include the introduction of new
Unsynchronized Service Discovery (USD) tests, migration of existing
Permission tests into a modernized framework, and the removal of legacy manual
Connection tests.
Multimedia and telecom enhancements
The Secure Playback test is introduced to validate secure playback capabilities,
ensuring correct video display and frame rate consistency
secure playback test setup. This is a CTS Verifier test and requires a
Peripheral Playback analysis tool.
Telecom test automation
Manual Telecom tests are replaced by the CtsTelecomTests automated module in
CTS-V-HOST.
CTS modules
The number of test modules and test cases are as follows:
Approximately 1,244 modules depending on the device type.
Approximately 3.1 million test cases for single ABI.
