示例1: TestDrawListRandom
void TestDrawListRandom(int numEntries) {
DrawList<MyData> list;
std::vector<double> configured;
std::vector<double> drawn;
const unsigned int cnt = numEntries;
const unsigned int numDraw = cnt * 4096;
double probSum = 0;
list.resize(cnt);
drawn.resize(cnt);
configured.resize(cnt);
// fill
for (unsigned int i = 0; i < cnt; ++i) {
double rnd = double(rand()) / double(RAND_MAX);
configured[i] = rnd;
list.set(i, MyData(i,i), rnd);
probSum += rnd;
}
// draw
for (unsigned int i = 0; i < numDraw; ++i) {
MyData& d = list.draw();
drawn[d.x]++;
}
// compare
for (unsigned int i = 0; i < cnt; ++i) {
double a = (configured[i] / probSum);
double b = (drawn[i] / numDraw);
ASSERT_NEAR(a, b, a*0.50); // allow 50% difference between cfg and drawn
}
