Introduction

This builds a test binary which contains the NLUnitTests and can be flashed onto a device. The device is controlled using the included RPCs, through the python test runner.

Building

• Download the Simplicity Commander command line tool, and ensure that commander is your shell search path. (For Mac OS X, commander is located inside Commander.app/Contents/MacOS/.)

• Download and install a suitable ARM gcc tool chain (For most Host, the bootstrap already installs the toolchain): GNU Arm Embedded Toolchain 12.2 Rel1

• Install some additional tools(likely already present for CHIP developers):

#Linux sudo apt-get install git libwebkitgtk-1.0-0 ninja-build

#Mac OS X brew install ninja

• Supported hardware:

  MG24 boards :

  • BRD2601B / SLWSTK6000B / Wireless Starter Kit / 2.4GHz@10dBm
  • BRD2703A / SLWSTK6000B / Wireless Starter Kit / 2.4GHz@10dBm
  • BRD4186A / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@10dBm
  • BRD4186C / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@10dBm
  • BRD4187A / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@20dBm
  • BRD4187C / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@20dBm

OR use GN/Ninja directly

      ```
      cd ~/connectedhomeip/src/test_driver/efr32/
      git submodule update --init
      source third_party/connectedhomeip/scripts/activate.sh
      export SILABS_BOARD=BRD4187C
      gn gen out/debug
      ninja -C out/debug
      ```

• To delete generated executable, libraries and object files use:

    ```
    cd ~/connectedhomeip/src/test_driver/efr32/
    rm -rf out/
    ```
  

Running The Tests

Build the runner using gn:

```
cd <connectedhomeip>/src/test_driver/efr32
gn gen out/debug
ninja -C out/debug runner
```

Or build using build script from the root

```
cd <connectedhomeip>
./scripts/build/build_examples.py --target linux-x64-nl-test-runner build
```

The runner will be installed into the venv and python wheels will be packaged in the output folder for deploying.

Then the python wheels need to installed using pip3.

```
pip3 install out/debug/chip_nl_test_runner_wheels/*.whl
```

Other python libraries may need to be installed such as

```
pip3 install pyserial
```

• To run the tests:

  python -m nl_test_runner.nl_test_runner -d /dev/ttyACM1 -f out/debug/matter-silabs-device_tests.s37 -o out.log
