Is there any place where I can find test vectors for point addition and doubling of ECC? I want to extensively test my implementation of point addition and doubling. I have only one test vector with me. I need more values to test.

In the web, I could find test vectors only for key pair generation and  signature verification. So if anybody can refer me a link containing test vectors, it will be of great help!

Thankyou.
You can check Elliptic Curve Calculator.
It has point addition and scalar multiplication. For doubling, adding the same points(P+P) should do the work.
