feat(fuzz): create initial seed corpus from forge test traces #10875
Description
Component
Forge
Describe the feature you would like
Tests contain valuable info on the sequence of interactions expected by a contract as well as input data selected by hopefully informed devs, so it would probably improve coverage guided fuzzing to insert this info into the corpus dir for mutation as opposed to starting from random
test_MyContract() {
MyContract.A(1,2,3)
MyContract.B("foo")
MyContract.C()
}
[ target: , calldata: abi.encode(MyContract.A(1,2,3)), target: , calldata: abi.encode(MyContract.B("foo")) ....
Related: the reverse can be done for reproducers to generate failing tests for debugging
