示例1: testClear
void LinkedHashMapTest::testClear() {
LinkedHashMap<int, std::string> hashMap;
hashMap.put(1, "one");
hashMap.put(3, "three");
hashMap.put(2, "two");
hashMap.clear();
CPPUNIT_ASSERT_EQUAL_MESSAGE("Clear failed to reset size", 0, hashMap.size());
for (int i = 0; i < 125; i++) {
CPPUNIT_ASSERT_THROW_MESSAGE(
"Failed to clear all elements",
hashMap.get(i),
NoSuchElementException);
}
// Check clear on a large loaded map of Integer keys
LinkedHashMap<int, std::string> map;
for (int i = -32767; i < 32768; i++) {
map.put(i, "foobar");
}
map.clear();
CPPUNIT_ASSERT_EQUAL_MESSAGE("Failed to reset size on large integer map", 0, map.size());
for (int i = -32767; i < 32768; i++) {
CPPUNIT_ASSERT_THROW_MESSAGE(
"Failed to clear all elements",
map.get(i),
