Is there a more efficient way to use assert with arrays in C? -

in 1 part of program need use assert test multiple arrays (5 sets total), , wondering if there's more efficient way besides doing right now, creating new array every time. fyi have assert.h @ beginning of program.

void unittest3d(void){     double test1[3] = {0,0,0};     double test2[3] = {5,0,0};     assert(find3ddistance(test1,test2) - 5) < 0.001);      double test3[3] = {-2, -3, 3.4};     double test4[3] = {-2, -3, -1.6};     assert(find3ddistance(test3,test4) - 5) < 0.001);      double test5[3] = {-2, -3.2, -5};     double test6[3] = {3, 1.8, 0};     assert(find3ddistance(test5,test6) - sqrt(75)) < 0.001);     return;     }
