Instant experience | further improve application device compatibility with cts-d

author / Android Partner engineer Sachiyo Sugimoto

Android Its advantage lies in its diverse equipment ecosystem ,Android Support more than 2.4 Ten thousand different types of equipment , And has billions of users around the world . since Android Early versions begin , We will continue to work on Android Compatibility program , To ensure carrying Android The equipment of the system can provide a stable and consistent environment for applications .

• Android Compatibility program

Android The core of the compatibility plan is the compatibility test suite (CTS), This kit contains 200 More than ten thousand are used for inspection Android Test cases implemented by the device , Ensure that developers' applications can run on various devices , And provide users with a consistent application experience .

The equipment manufacturer will run throughout the development of the equipment CTS, And find and fix errors as soon as possible . these years , We continue to expand the suite by adding new test cases , Now CTS Already contains more than 200 Ten thousand test cases .CTS Continue to expand , We continue to introduce new test cases to cover the following Android New fields involved in development .

Although most CTS The tests are conducted by Android Written by an engineer , But we believe that application developers have unique views on the issue of device compatibility . therefore , In order to combine the feedback and suggestions of application developers to further enhance CTS, We have launched a new test suite built and run by application developers —— CTS-D.

What is? CTS-D？

CTS-D It is a new one supported by application developers CTS modular , Focus on the pain points you see in your respective fields . You can build test cases and contribute them to CTS-D To help other developers find these problems , It also works CTS-D Suite to verify compatibility . In the long run , We hope to work with you and Android The developer community works closely , Better help CTS-D Development .

We know that many developers have created their own test cases , To verify the compatibility of different devices . We hope to cooperate with you , Introduce these tests into AOSP, You can view the first submission , Learn about the early contributions made by the community CTS-D test .

adopt CTS-D, We can better extend this type of test , To help device manufacturers and application developers identify and share problems more effectively .

How to use CTS-D？

CTS-D Is an open source test suite , Can be found in AOSP Upper use , Therefore, any application developer can use it as a testing tool . Use CTS-D Help to further reduce the number of application developers 、 Equipment manufacturer and Google Communication costs between , So as to solve the problem quickly and efficiently .

If a device fails CTS-D test , You can use the issue tracking page template to feed back issues to us . After verifying the problem of the equipment , Will work with partners to solve . Besides , We also highly recommend equipment manufacturers to use CTS-D To find out the problem , And reduce its impact .

Start using CTS-D！

If you plan to use CTS-D, Please submit the test code to AOSP Before , Use the problem tracking page template to share your test plan with us .Android The team will review the test plan and evaluate whether your test meets the conditions . We expect developers to submit more test cases about power management .

And CTS equally , new CTS-D Test cases must meet the qualification requirements , And can only execute the following : 

1. Android All public... Described in the developer documentation API Behavior ;

2. Android Compatibility definition document (CDD) All of the MUST requirement ;

3. AOSP Existing in CTS Uncovered test cases .

Please note that , We need some time to review the new CTS-D The test case , Thank you for your patience . You are welcome to try it as soon as possible CTS-D, Let's work together to create a better Android Experience ！ We also welcome your continued attention "Android developer " WeChat official account , Learn more in time .
