X Test Suite

Introduction

The X test suite (XTS) subsystem contains a set of OpenHarmony certification test suites, including the currently supported application compatibility test suite (ACTS) and the device compatibility test suite (DCTS) that will be supported in the future.

This subsystem contains the ACTS and tools software package.

  • The acts directory stores the source code and configuration files of ACTS test cases. The ACTS helps device vendors detect the software incompatibility as early as possible and ensures that the software is compatible to OpenHarmony during the entire development process.
  • The tools software package stores the test case development framework related to acts.

Devices

OpenHarmony supports the following device types:

  • Mini-System Devices (reference memory ≥ 128 KB)

    Such devices are equipped with MCU processors such as ARM Cortex-M and 32-bit RISC-V. They provide rich short-distance connection and peripheral bus access capabilities. Typical products include LinkIoT module devices and sensors in the smart home field. The LinkIoT module is usually used for smart Internet of Things (IoT) devices as the hardware module that implements connectivity functions. In the smart home field, the LinkIoT module is integrated into devices by vendors. For example, a LinkIoT module provides WLAN/Bluetooth access and data connection, and it usually communicates with the chip of smart home devices via a universal asynchronous receiver-transmitter (UART) or general-purpose input/output (GPIO) interface.

  • Small-System Devices (reference memory ≥ 1 MB)

    Such devices are equipped with application processors such as ARM Cortex-A. They provide higher security capabilities, standard graphics framework, and multimedia capabilities for video encoding and decoding. Typical products include IP cameras, electronic cat eyes, and routers in the smart home field, as well as event data recorders (EDRs) in the smart travel field.

  • Standard-System Devices (reference memory ≥ 128 MB)

    Such devices are equipped with application processors such as ARM Cortex-A. They provide a complete application framework supporting enhanced interaction, 3D GPU, hardware composer, diverse components, and rich animations. Typical products include high-end refrigerator displays.

  • Large-System Devices (reference memory ≥ 1 GB)

    Such devices are equipped with application processors such as ARM Cortex-A and provide a complete compatible application framework. Typical products include smart TVs and smart watches.

Table 3 Test types

Type

Definition

Function

Tests the correctness of both service and platform functionalities provided by the tested object for end users or developers.

Performance

Tests the processing capability of the tested object under specific preset conditions and load models. The processing capability is measured by the service volume that can be processed in a unit time, for example, call per second, frame per second, or event processing volume per second.

Power

Tests the power consumption of the tested object in a certain period of time under specific preset conditions and load models.

Reliability

Tests the service performance of the tested object under common and uncommon input conditions, or specified service volume pressure and long-term continuous running pressure. The test covers stability, pressure handling, fault injection, and Monkey test times.

Security

  • Tests the capability of defending against security threats, including but not limited to unauthorized access, use, disclosure, damage, modification, and destruction, to ensure information confidentiality, integrity, and availability.
  • Tests the privacy protection capability to ensure that the collection, use, retention, disclosure, and disposal of users' private data comply with laws and regulations.
  • Tests the compliance with various security specifications, such as security design, security requirements, and security certification of the Ministry of Industry and Information Technology (MIIT).

Global

Tests the internationalized data and localization capabilities of the tested object, including multi-language display, various input/output habits, time formats, and regional features, such as currency, time, and culture taboos.

Compatibility

  • Tests backward compatibility of an application with its own data, the forward and backward compatibility with the system, and the compatibility with different user data, such as audio file content of the player and smart SMS messages.
  • Tests system backward compatibility with its own data and the compatibility of common applications in the ecosystem.
  • Tests software compatibility with related hardware.

User

Tests user experience of the object in real user scenarios. All conclusions and comments should come from the users, which are all subjective evaluation in this case.

Standard

Tests the compliance with industry and company-specific standards, protocols, and specifications. The standards here do not include any security standards that should be classified into the security test.

Safety

Tests the safety property of the tested object to avoid possible hazards to personal safety, health, and the object itself.

Resilience

Tests the resilience property of the tested object to ensure that it can withstand and maintain the defined running status (including downgrading) when being attacked, and recover from and adapt defense to the attacks to approach mission assurance.

C-based Test Case Development and Compilation (for Mini-System Devices)

Developing test cases for mini-system devices

The HCTest framework is used to support test cases developed with the C language. HCTest is enhanced and adapted based on the open-source test framework Unity.

  1. Access the test/xts/acts repository where the test cases will be stored.

    ├── acts
    │ └──subsystem_lite
    │ │ └── module_hal
    │ │ │ └── BUILD.gn
    │ │ │ └── src
    │ └──build_lite
    │ │ └── BUILD.gn
  2. Write the test case in the src directory.

    1 Import the test framework header file.

    #include "hctest.h"
    1. Use the LITE_TEST_SUIT macro to define names of the subsystem, module, and test suite.
    /**  
    * @brief  Registers a test suite named IntTestSuite.
    * @param  test Subsystem name
    * @param  example Module name
    * @param  IntTestSuite Test suite name
    */
    LITE_TEST_SUIT(test, example, IntTestSuite);
    1. Define Setup and TearDown.

    Format: Test suite name+Setup, Test suite name+TearDown.

    The Setup and TearDown functions must exist, but function bodies can be empty.

    1. Use the LITE_TEST_CASE macro to write the test case.

    Three parameters are involved: test suite name, test case name, and test case properties (including type, granularity, and level).

    LITE_TEST_CASE(IntTestSuite, TestCase001, Function | MediumTest | Level1) 
    {  
      // Do something 
    };
    1. Use the RUN_TEST_SUITE macro to register the test suite.
    RUN_TEST_SUITE(IntTestSuite);
  3. Create the configuration file (BUILD.gn) of the test module.

    Create a BUILD.gn (example) compilation file in each test module directory. Specify the name of the compiled static library and its dependent header file and library in the compilation file. The format is as follows:

    import("//test/xts/tools/lite/build/suite_lite.gni")
    hctest_suite("ActsDemoTest") {
        suite_name = "acts"
        sources = [
            "src/test_demo.c",
        ]
        include_dirs = [ ]
        cflags = [ "-Wno-error" ]
    }
  4. Add compilation options to the BUILD.gn file in the acts directory.

    You need to add the test module to the test/xts/acts/build_lite/BUILD.gn script in the acts directory.

    lite_component("acts") {  
        ...
        if(board_name == "liteos_m") {
            features += [    
                ...
                "//xts/acts/subsystem_lite/module_hal:ActsDemoTest"
            ]    
        }
    }
  5. Run compilation commands.

    Test suites are compiled along with version compilation. The ACTS is compiled together with the debug version.

    NOTE: The ACTS compiles middleware as a static library, which will be linked to the image.

C-based Test Case Execution (for Mini-System Devices)

Executing test cases for mini-system devices

Burn the image into the development board.

Executing the test

  1. Use a serial port tool to log in to the development board and save information about the serial port.
  2. Restart the device and view serial port logs.

Analyzing the test result

View the serial port logs, whose format is as follows:

The log for each test suite starts with Start to run test suite: and ends with xx Tests xx Failures xx Ignored.

C++-based Test Case Development and Compilation (for Small-, Standard-, and Large-System Devices)

Developing test cases for small-system devices

The HCPPTest framework is enhanced and adapted based on the open-source framework Googletest.

  1. Access the test/xts/acts repository where the test cases will be stored.

    ├── acts
    │ └──subsystem_lite
    │ │ └── module_posix
    │ │ │ └── BUILD.gn
    │ │ │ └── src
    │ └──build_lite
    │ │ └── BUILD.gn
  2. Write the test case in the src directory.

    1. Import the test framework header file.

    The following statement includes gtest.h.

    #include "gtest/gtest.h"
    1. Define Setup and TearDown.
    using namespace std;
    using namespace testing::ext;
    class TestSuite: public testing::Test {
    protected:
    // Preset action of the test suite, which is executed before the first test case
    static void SetUpTestCase(void){
    }
    // Test suite cleanup action, which is executed after the last test case
    static void TearDownTestCase(void){
    }
    // Preset action of the test case
    virtual void SetUp()
    {
    }
    // Cleanup action of the test case
    virtual void TearDown()
    {
    }
    };
    1. Use the HWTEST or HWTEST_F macro to write the test case.

    HWTEST: definition of common test cases, including the test suite name, test case name, and case annotation.

    HWTEST_F: definition of SetUp and TearDown test cases, including the test suite name, test case name, and case annotation.

    Three parameters are involved: test suite name, test case name, and test case properties (including type, granularity, and level).

    HWTEST_F(TestSuite, TestCase_0001, Function | MediumTest | Level1) {
    // Do something
    }
  3. Create a configuration file (BUILD.gn) of the test module.

    Create a BUILD.gn compilation file in each test module directory. Specify the name of the compiled static library and its dependent header file and library in the compilation file. Each test module is independently compiled into a .bin executable file, which can be directly mounted to the development board for testing.

    Example:

    import("//test/xts/tools/lite/build/suite_lite.gni")
    hcpptest_suite("ActsDemoTest") {
        suite_name = "acts"
        sources = [
            "src/TestDemo.cpp"
        ]
    
        include_dirs = [
            "src",
            ...
        ]
        deps = [
            ...
        ]
        cflags = [ "-Wno-error" ]
    }
    
  4. Add compilation options to the BUILD.gn file in the acts directory.

    Add the test module to the test/xts/acts/build_lite/BUILD.gn script in the acts directory.

     lite_component("acts") {  
    ...
    else if(board_name == "liteos_a") {
            features += [
                ...
                "//xts/acts/subsystem_lite/module_posix:ActsDemoTest"
            ]
        }
    }
  5. Run compilation commands.

    Test suites are compiled along with the version compilation. The ACTS is compiled together with the debug version.

    NOTE: The ACTS for a small system device is independently compiled to an executable file (.bin) and archived in the suites\acts directory of the compilation result.

C++-based Test Case Execution (for Small-, Standard-, and Large-System Devices)

Executing test cases for small-system devices

Currently, test cases are shared by the NFS and mounted to the development board for execution.

Setting up the environment

  1. Use a network cable or wireless network to connect the development board to your PC.

  2. Configure the IP address, subnet mask, and gateway for the development board. Ensure that the development board and the PC are in the same network segment.

  3. Install and register the NFS server on the PC and start the NFS service.

  4. Run the mount command for the development board to ensure that the development board can access NFS shared files on the PC.

    Format: mount NFS server IP address:/NFS shared directory /development board directory nfs

    Example:

    mount 192.168.1.10:/nfs /nfs nfs

Executing test cases

Execute ActsDemoTest.bin to trigger test case execution, and analyze serial port logs generated after the execution is complete.
