示例1: SECTION
#include <stdio.h>
#include <unordered_map>
#include "huffman.h"
using namespace ptlmuh006;
TEST_CASE("Files correctly compressed", "[compression]") {
HuffmanTree huff;

//GIVEN: A string of data
std::string data = "aaabbbccc dddddddddd\nccc";
//WHEN: We count the frequency of the characters in the string of data
std::unordered_map<char, int> freqTbl = huff.countFrequency(data);
//THEN: We should get a correct frequency table with characters mapped to tallys
REQUIRE( freqTbl.size() == 6 );
REQUIRE( freqTbl['a'] == 3 );
REQUIRE( freqTbl['b'] == 3 );
REQUIRE( freqTbl['c'] == 6 );
