u-boot is cable of support the I2C protocol. if the touchscreen communication protocol is I2C by using i2c command we cant communicate the i2c ?

Yes, I2C communication is supported, but there are no drivers for touchscreen in U-boot.

by using i2c protocol tochscreen can be communicated. so my doubt is by using i2c command can i test the touchscreen

You will be able to test communication with the TS controller, however you will not be able to visualize TS activity on the display.
