XTS Test Case Development Guide

Introduction

The X test suite (XTS) subsystem contains a set of OpenHarmony compatibility 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 with OpenHarmony during the entire development process.

• The tools software package stores the test case development framework related to acts.

System Types

The following system types are supported:

• Mini system The mini system fits into the devices that come with MCU processors, such as Arm Cortex-M and 32-bit RISC-V, and memory greater than or equal to 128 KiB. This system provides a variety of lightweight network protocols, a lightweight graphics framework, and a wide range of read/write components with the Internet of Things (IoT) bus. Typical products include connection modules, sensors, and wearables for smart home.

• Small system The small system fits into the devices that come with application processors, such as Arm Cortex-A, and memory greater than or equal to 1 MiB. This system provides higher security capabilities, a standard graphics framework, and video encoding and decoding capabilities. Typical products include smart home IP cameras, electronic cat eyes, and routers, and event data recorders (EDRs) for easy travel.

• Standard system The standard system fits into the devices that come with application processors, such as Arm Cortex-A, and memory greater than or equal to 128 MiB. This system provides a complete application framework supporting enhanced interaction, 3D GPU, hardware composer, diverse components, and rich animations. The standard system applies to high-end refrigerator displays.

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

Developing test cases for the mini system

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

1. 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  register 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);
   

2. Create a configuration file (BUILD.gn) of the test module. Create a BUILD.gn (example) build file in each test module directory. Specify the name of the built static library and its dependent header file and library in the build 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" ]
   }

1. Add build 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"
           ]    
       }
   }

1. Run build commands. Test suites are built along with the version build. The ACTS is built together with the debug version.

NOTE The ACTS build middleware is a static library, which will be linked to the image.

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

Executing test cases for the mini system

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 Standard and Small Systems)

Developing test cases for small-system devices (For examples of the standard system, go to the global/i18n_standard directory.)

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

1. 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
     }
   

2. Create a configuration file (BUILD.gn) of the test module. Create a BUILD.gn build file in each test module directory. Specify the name of the built static library and its dependent header file and library in the build file. Each test module is independently built into a .bin executable file, which can be directly pushed 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" ]
   }
   

1. Add build 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"
           ]
       }
   }

1. Run build commands. Test suites are built along with the version build. The ACTS is built together with the debug version. > NOTE > > The ACTS for the small system is independently built to an executable file (.bin) and archived in the suites\acts directory of the build result.

C++-based Test Case Execution (for Standard and Small Systems)

Executing test cases for the small system

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 on 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.

JavaScript-based Test Case Development (for the Standard System)

The HJSUnit framework is used to support automated tests of OpenHarmony applications that are developed using the JavaScript language based on the JS application framework.

Basic syntax of test cases

The test cases are developed with the JavaScript language and must meet the programming specifications of the language.

Table 7 Basic syntax of test cases

Use the standard syntax of Jasmine to write test cases. The ES6 specification is supported.

1. Store the test cases in the entry/src/main/js/test directory, whose structure is as follows:

   ├── BUILD.gn   
   │ └──entry
   │ │ └──src
   │ │ │ └──main
   │ │ │ │ └──js
   │ │ │ │ │ └──default               
   │ │ │ │ │ │ └──pages
   │ │ │ │ │ │ │ └──index             
   │ │ │ │ │ │ │ │ └──index.js        # Entry file
   │ │ │ │ │ └──test                  # Test code 
   │ │ │ └── resources                # HAP resources
   │ │ │ └── config.json              # HAP configuration file

1. Start the JS test framework and load test cases. The following is an example for index.js:

   // Start the JS test framework and load test cases.
   import {Core, ExpectExtend} from 'deccjsunit/index'
   
   export default {
       data: {
           title: ""
       },
       onInit() {
           this.title = this.$t('strings.world');
       },
       onShow() {
           console.info('onShow finish')
           const core = Core.getInstance()
           const expectExtend = new ExpectExtend({
               'id': 'extend'
           })
           core.addService('expect', expectExtend)
           core.init()
           const configService = core.getDefaultService('config')
           configService.setConfig(this)
           require('../../../test/List.test')
           core.execute()
       },
       onReady() {
       },
   }

1. Write a unit test case by referring to the following example:

   // Use HJSUnit to perform the unit test.
   describe('appInfoTest', function () {    
       it('app_info_test_001', 0, function () {
           var info = app.getInfo()
           expect(info.versionName).assertEqual('1.0')
           expect(info.versionCode).assertEqual('3')
       })
   }) 

JavaScript-based Test Case Packaging (for the Standard System)

For details about HAP package compilation, see JS application development guide for the standard system.

Full Compilation (for the Standard System)

1. Perform full compilation. Command:

   ./build.sh suite=acts system_size=standard

Test case output directory: out/release/suites/acts/testcases

Test framework and case output directory: out/release/suites/acts (The test suite execution framework is compiled during case compilation.)

Full Test Case Execution (for Small and Standard Systems)

Setting up a test environment

Install Python 3.7 or a later version on a Windows environment and ensure that the Windows environment is properly connected to the test device.

Test execution directory (corresponding to the out/release/suites/acts directory generated during compilation)

├── testcase                       # Directory for storing test suite files
│ └──xxx.hap                       # HAP file executed by the test suite
│ └──xxx.json                      # Execution configuration file of the test suite
├── tools                          # Test framework tool directory
├── run.bat                        # File for starting the test suite on the Windows platform
├── report                         # Directory for storing the test reports

Executing test cases

1. On the Windows environment, locate the directory in which the test cases are stored (out/release/suites/acts, copied from the Linux server), go to the directory in the Windows command line interface (CLI), and run acts\run.bat.

2. Enter the command for executing the test case.

   • Execute all test cases.

     run acts
