+# How to write C++ ESPHome unit tests
+
+1. Locate the folder with your component or create a new one with the same name as the component.
+2. Write the tests. You can add as many `.cpp` and `.h` files as you need to organize your tests.
+
+**IMPORTANT**: wrap all your testing code in a unique namespace to avoid linker collisions when compiling
+testing binaries that combine many components. By convention, this unique namespace is `esphome::component::testing`
+(where "component" is the component under test), for example: `esphome::uart::testing`.
+
+
+## Running component unit tests
+
+(from the repository root)
+```bash
+./script/cpp_unit_test.py component1 component2 ...
+```
+
+The above will compile and run the provided components and their tests.
+
+To run all tests, you can invoke `cpp_unit_test.py` with the special `--all` flag:
+
+```bash
+./script/cpp_unit_test.py --all
+```
+
+To run a specific test suite, you can provide a Google Test filter:
+
+```bash
+GTEST_FILTER='UART*' ./script/cpp_unit_test.py uart modbus
+```
+
+The process will return `0` for success or nonzero for failure. In case of failure, the errors will be printed out to the console.
