示例1: SkASSERT
DEF_TEST(PathOpsDPoint, reporter) {
for (size_t index = 0; index < tests_count; ++index) {
const SkDPoint& pt = tests[index];
SkASSERT(ValidPoint(pt));
SkDPoint p = pt;
REPORTER_ASSERT(reporter, p == pt);
REPORTER_ASSERT(reporter, !(pt != pt));
SkDVector v = p - pt;
p += v;
REPORTER_ASSERT(reporter, p == pt);
p -= v;
REPORTER_ASSERT(reporter, p == pt);
REPORTER_ASSERT(reporter, p.approximatelyEqual(pt));
SkPoint sPt = pt.asSkPoint();
p.set(sPt);
REPORTER_ASSERT(reporter, p == pt);
REPORTER_ASSERT(reporter, p.approximatelyEqual(sPt));
REPORTER_ASSERT(reporter, p.roughlyEqual(pt));
p.fX = p.fY = 0;
REPORTER_ASSERT(reporter, p.fX == 0 && p.fY == 0);
REPORTER_ASSERT(reporter, p.approximatelyZero());
REPORTER_ASSERT(reporter, pt.distanceSquared(p) == pt.fX * pt.fX + pt.fY * pt.fY);
REPORTER_ASSERT(reporter, approximately_equal(pt.distance(p),
sqrt(pt.fX * pt.fX + pt.fY * pt.fY)));
