c++利用对象实现简单数据的测试:
class TestDataEmptyArray {
public:
static vector<int> get_array() {
std::vector<int> vec {};
return vec;
}
};
class TestDataUniqueValues {
public:
static vector<int> get_array() {
// declare a vector with minimum 2 values that are unique
std::vector<int> vec {1, 2, 3, 4, 5};
return vec;
}
static int get_expected_result() {
//declare the former vector
std::vector<int> vec {get_array()};
//search for the smallest element with algorithm
std::vector<int>::iterator result = std::min_element(std::begin(vec), std::end(vec));
//return the index of the smallest element as a type int
return std::distance(std::begin(vec), result);
}
};
class TestDataExactlyTwoDifferentMinimums {
public:
static vector<int> get_array() {
//declare a vector that has atleast 2 non unique number in it
std::vector<int> vec {1, 2, 3, 4, 3, 2, 1};
return vec;
}
static int get_expected_result() {
//declare tha former vector
std::vector<int> vec {get_array()};
////search for the smallest element with algorithm
std::vector<int>::iterator result = std::min_element(std::begin(vec), std::end(vec));
//return the index of the smallest element as a type int
return std::distance(std::begin(vec), result);
}
};
python 利用装饰器进行实现
class TestDataEmptyArray(object):
@staticmethod
def get_array():
return []
class TestDataUniqueValues(object):
@staticmethod
def get_array():
arr = [2,3,4,6,5]
return arr
@staticmethod
def get_expected_result():
return 0
class TestDataExactlyTwoDifferentMinimums(object):
@staticmethod
def get_array():
arr = [2,3,4,2,4]
return arr
@staticmethod
def get_expected_result():
return 0
相比较来说,python实现的代码更加简洁。
