Simulated Device How-To (Linux)

This document contains instructions on how to build, run, and interact with a simulated device. All virtual accessories live in examples/placeholder/linux/apps.

Each accessory needs to be hosted into a subfolder. It will be the name of the application. For example app1 will create a binary named chip-app1.

If some parameters need to be overridden, a CHIPProjectConfig.h file can be placed under an ‘include’ folder into the app folder. For example examples/placeholder/linux/apps/app1/include/CHIPProjectConfig.h

Simulated Device: simulation of an application in which tests can be added. It is defined by a ZAP config file and tests can be added with a YAML file.

Prerequisite

• Building Prerequisites
• Prepare For Building
• Code Generate
• ZAP Installed

Building the default Simulated App with Script

In order to utilize the app against a commissioner or controller, the app will need to be specifically built.

1. To build the chip-app1 binary completing the following steps:

   ./scripts/examples/gn_build_example.sh examples/placeholder/linux out/debug/simulated/ chip_tests_zap_config=\"app1\"
   

Build the App with gn and ninja (alternative)

In order to utilize the app against a commissioner or controller, the app will need to be specifically built.

1. To only build the chip-app1 binary completing the following steps:

   source scripts/activate.sh
   gn gen --check --root=examples/placeholder/linux out/simulated --args="chip_tests_zap_config=\"app1\""
   ninja -C out/simulated
   

Running the app

Now that the building is completed there is a chip-app1 binary created. This binary can be executed on a linux os.

./out/debug/simulated/chip-app1

Running the app with test parameter

Now that the building is completed there is a chip-app1 binary created. This binary can be executed on a linux os with test commands.

./scripts/tests/yaml/runner.py [TEST NAME] app1

Interacting with the simulated app

Now that the building the app and starting it is complete, you will be able to interact with it using chip-tool

1. Follow the instruction to build chip-tool in the chip-tool readme.

2. Run this command to commission with whatever is listed on the “SetupQRCode:” line in the log output:

     ./out/debug/standalone/chip-tool pairing code 0x654321 MT:-24J0AFN00KA0648G00
   

3. Most tests will start at this point and now an send cluster commands with chip-tool as follow.

   ./out/debug/standalone/chip-tool onoff on 0x654321 1
   ./out/debug/standalone/chip-tool onoff read on-off 0x654321 1
   ./out/debug/standalone/chip-tool onoff write on-time 1 0x654321 1
   

   See chip-tool readme for additional commands.

Adding simulated Tests via YAML

In order to validate commissioner/controller behavior, tests need to be added to the simulated device test framework. To achieve this, YAML files are created.

1. YAML test file are located in YAML folder

2. Test names must follow a strict format dues to CI of test recognition. The format is as follows:

   • Test_TC_[CATEGORY ABBREVIATION]_[SECTION NUMBER]_[SUBSECTION NUMBER]_Simulated.yaml
   • IMPORTANT: The test name must end in Simulated with the capital.

3. Available properties can be found in YAML Test Name

4. An Additional property is as follows:

   Name	Description
   wait	The command that is expected to be received on the app from the controller.

5. Test_TC_DM_1_3_Simulated is an example of a written test that runs on the simulated device.
