| The macro `MBED_TEST_MODE` is defined when building tests with Mbed CLI versions 1.9.0 and later. You can wrap your application's `main()` function in a preprocessor check to prevent multiple `main()` functions from being defined: | ||

|

| ```c++ | ||
| #if !MBED_TEST_MODE |

For consistency shall this be #ifndef MBED_TEST_MODE? See https://github.com/ARMmbed/pelion-ready-example/blob/master/main.cpp

I went with #if !MBED_TEST_MODE so you could also set MBED_TEST_MODE=0 for testing purposes. Specifying it as #ifndef would always evaluate to false, even if the macro was set to 0. A similar pattern is used within Mbed OS: ARMmbed/mbed-os#8957
