# Testing
In addition to cross-compiling the Dart SDK, test items can also be cross-compiled. Even without the corresponding hardware, you can quickly verify if the source code modifications you made are correct. Below is a simple method for development on the riscv64 platform for your reference.

If you have configured QEMU for RISCV64, you can merge steps 3 and 4 into a single command (omitting some print parameters):
