Is there a flash memory test for the ESP8266

Is there a program / sketch that I can load into my ESP and have it tell me the TRUE flash memory size? I have had several boards that will work fine, but then I load another board with the same program and it fails. I suspect fake or bad flash memory, but I have no way to prove it.

Look in examples ESP8266 for CheckFlashConfig.

There are also different ways to connect some memory chips. Some boards use fewer pins to connect to the flash.
When programming in Tools - Flash Mode select DOUT Compatible.
