你这是 自动化测试 的面试题?? 课程作业?? 我也没用过这个pytest,也不知道是否理解正确了题意(甚至觉得题目有点问题。。)
现学现卖,第一题大概这样实现吧:# conftest.py
import pytest
import pymysql
@pytest.fixture(scope='function')
def db_session():
conn = pymysql.connect(
host='localhost',
user='root',
password='123456',
database='mydb',
)
yield conn
# test_pymysql.py
import pymysql
def test_init(db_session):
assert db_session.user.decode() == 'root'
assert db_session.db.decode() == 'mydb'
# assert 0
def test_conn(db_session):
assert db_session.open == True
def test_execute_sql(db_session):
conn = db_session
with conn.cursor() as cursor:
cursor.execute("drop table if exists foo;")
cursor.execute("create table if not exists foo(`id` int, `name` varchar(20), `age` int);")
cursor.execute("insert into foo(`id`,`name`,`age`) values(1001, 'Alice', 18), (1002, 'Bill', 20);")
cursor.execute("commit;")
cursor.execute("select * from foo")
result = cursor.fetchall()
# for row in result: print(row)
assert result == ((1001, 'Alice', 18), (1002, 'Bill', 20))
# assert 0
def test_close_conn(db_session):
db_session.close()
try:
db_session.ping(reconnect=False)
except pymysql.err.Error as e:
# print(e, e.args)
assert 'Already closed' in e.args[0]
# assert 'Not closed ?' in e.args # deliberately fails
