初始化类的属性的2种写法：
如下要注意python对文件名称、类、方法名的命名
方式一：原始的定义
class User1:
# 初始化账号和密码
def __init__(self):
# 账号和密码
self.__username = None
self.__password = None
def getnsername(self):
return self.__username
def getpassword(self):
return self.__password
def setusername(self, username):
self.__username = username
def setpassword(self, password):
self.__password = password
if __name__ == '__main__':
usr1 = User1()
usr1.setusername("admin")
usr1.setpassword("8888")
print(usr1.getnsername())
print(usr1.getpassword())
方式二：可以跳过pytest的限制（pytest的对类的方法不能有init()方法）
class User:
# 初始化类的属性：账号、密码
__username = None
__password = None
def getname(self):
return self.__username
def getpassword(self):
return self.__password
def setusername(self, username):
self.__username = username
def setpassword(self, password):
self.__password = password
if __name__ == '__main__':
usr = User()
usr.setusername("admin")
usr.setpassword("8888")
print(usr.getname())
print(usr.getpassword())
三、pytest的命名规则：
1.模块名必须以test_开头或者以_test结尾
2.测试类必须以Test开头，并且不能有init方法
3.测试方法以test开头
四、方式二和java的对类的定义是一样的：
创建User类：（可以对比其相似度）
public class User {
private String username;
private String password;
public User() {
super();
}
public String getUsername() {
return username;
}
public String getPassword() {
return password;
}
public void setUsername(String username) {
this.username = username;
}
public void setPassword(String password) {
this.password = password;
}
public User(String username, String password) {
this.username = username;
this.password = password;
}
@Override
public String toString() {
return "User{" +
"username='" + username + '\'' +
", password='" + password + '\'' +
'}';
}
public static void main(String[] args) {
User user = new User();
user.setUsername("admin");
user.setPassword("8888");
System.out.println(user.getUsername());
System.out.println(user.getPassword());
}
}
