We all know that there are loads of APIs and functions that we can automatically test with CTS-traded. Still, the point is that wat about all the other APIs and services that can’t be tested within a computerized environment?

Thus, CTS Verifier appears every time an API or a function that cannot be examined on a device outwardly standard input. These are the situations that are involved in audio quality, touchscreen effectiveness, accelerometer accuracy, and reactivity, camera quality, and specialties that are meant so particularly for human communication that they are difficult to test without social interaction.

As a common rule, installed devices should support a high degree of customization. They should be always-on and offer themselves as an always-present gateway to the Internet.

Every established device company aspires to customize its devices by increasing the functionality of the OS as much as attainable. There is a cause of why Android was designed as a robust platform for controlling aftermarket applications.

Thus, after customizing Android as per device requirements, if the user needs to run Google play store applications, they oblige to provide what is identified as compatibility to these applications.

CTS stands for Compatibility Test Suite. It is a popular-grade test suite, designed by Google, to recognize areas of conflict at the quickest attainable stage of growth and to assure that all floated features of the Android OS operate to Google’s high measures.

Hence, it is necessary for devices running an Android operating system to have achieved CTS testing, whether that device is a phone, tablet, smartwatch, TV device, in-car system, or, indeed, any other product of Android that may be accesible.

However, the CTS works on a desktop machine and executes test cases straight on the attached devices or an emulator. Well, CTS is a collection of unit tests designed to be combined into the daily workflow of the engineers developing a tool. Thus, its primary purpose is to expose incompatibilities at the beginning and to assure that the software stays cooperative throughout the development method.

Well, the CTS is an automatic testing mechanism which comprises two major software components:-

  • The CTS works on your desktop or laptop and controls test execution.
  • Singular test cases are performed on the Device Under Test (DUT).
  • The test events are written as JUnit tests in Java and packaged as Android .apk files to work on the actual Android device target.

The CTS Verifier is used for standardized testing, which implements tests for APIs and functions that can’t be tested on a fixed device outwardly manual input. Illustrations include Accelerometer, audio quality, etc.

The CTS Verifier is a device utilized for manual testing and covers the following software elements:-

  • The CTS verifier application that is administered on the device below tests and assembles the results.
  • The executable or script that are administered on the desktop or laptop to give data or additional authority for some test instances in the CTS Verifier app.

Requirements to Setup and run Android CTS Verifier

All the requirement that you need while setting up a CTS verifier:-

  • The Android device that has confirmed Android API adaptability by actively passing the CTS. This is the device below test (DUT).
  • Linux computer with a USB 2.0 cooperative port. All attachments to the DUT go by this port.
  • Thus, the second Android device with a recognized cooperative Bluetooth, Wi-Fi direct, and NFC host card emulation (HCE) implementation.
  • Lastly, a Wi-Fi router configured with an access point name and password. The router should have the capacity to disconnect from the Internet, but not powered off.

Well, achieving CTS compatibility for an Android device is a significant step to obtain GMS License, and eInfochips just befall to be one of the few service companies that can assist you in getting a GMS License. Thus, if a customer requires to validate their product for Android compatibility, it can help them by these following ways:-

  • Test the Android-based product and provide a detailed analysis report based on the result generated by CTS.
  • Provide a solution for displeased CTS tests on your product.
  • CTS customization targeted to your product and advanced functionalities.

Moreover, there are four types of test cases that are included in CTS:-

  • Unit Tests: To examine atomic units of code inside the Android platform; for example, a single class, just as java.util.HashMap.
  • Functional Tests: To examine a mixture of APIs together in higher-level use-cases.
  • Robustness Tests: To examine the persistence of the system below stress.
  • Performance Tests: To examine the production of the system against determined benchmarks, for illustration, presenting the number of frames per second.


However, we have implemented a full guide about the CTS verifier. Covering all is key points with proper explanation. Thus we hope that this article will help you, and it may be benefited with your manual work and tests.
