Problem with "Nothing to build"

I have a device that similar to arduino uno board “guizduino SE”. I try to store and program it by platformio in vs code. it turns out that say “Nothing to build. Please put your test suites to the ‘C:\Users\User\Documents\PlatformIO\Projects\Test_2\test’ folder
Uploading stage has failed, see errors above. Use pio test -vvv option to enable verbose output.” I hope you help me with my problem. thank you inadvance.
