unittest

1.执行命令：

python -m unittest E:\lpjx-ui_test\lpjx-web-ui\testcase\web\testcases_pytest\test_XT-0501-002.py

python -m unittest E:\lpjx-ui_test\lpjx-web-ui\testcase\web\testcases_pytest\test_login_DL-001.py

unittest.main(argv=['', 'TestAdd.test_add']

2.组件：

3.TestCase使用方法：

4.断言方法：

5.TestSuite使用： 注意：运行需要借助于TextTestRunner类

6.TestLoader使用：

discover(test_dir, pattern=匹配模式)

参数说明：

• test_dir: 为指定的测试用例的目录,它会搜索该目录的所有文件
• pattern：为匹配模式，如要查找所有的.py格式文件，你就可以写为'test*.py'，这样就会搜索test_dir目录下所有以test开头，以py结尾的文件。

7.TextTestRunner使用：

8.参数化:需先导包：ddt,parametrized

- 传单个字符串：
@data("bb")
def test_run_b(self,b):
    print(b)     #bb

@data(("a","b","c","d"))
@unpack
def test_run_c(self,para1,para2,para3,para4):
    print(para1,para2,para3,para4)   #a b c d

@data(["a", "b", "c", "d"])
@unpack
def test_run_d(self, para1, para2, para3, para4):
    print(para1, para2, para3, para4)   #a b c d

- 传几组字符串-data  字典怎么传？
@data(("ae","be"), ("ce","de"))
@unpack
def test_run_e(self, para1, para2): #会生成2条用例
    print("test_run_e:"+para1+" "+ para2)   
#.test_run_e:ae be
#.test_run_e:ce de

@data(["aa", "bb"], ["cc", "dd"])
@unpack
def test_run_f(self, para1, para2):  # 会生成2条用例
    print(" test_run_f:"+para1+" "+para2)
#. test_run_f:aa bb
#. test_run_f:cc dd

@data({"aa":"bb"}, {"cc":"dd"}) #字典报错???
@unpack
def test_run_g(self, aa, cc):  # 会生成2条用例
    print(" test_run_g:"+aa+" "+cc)

- 传几组字符串-parameterized
@parameterized.expand([("ai","bi"), ("ci","di")])
def test_run_i(self, username, password):
    print(" test_run_i:" + username + " " + password)
#. test_run_i:ai bi
#. test_run_i:ci di

- 传json文件
{
  "user1": {"username": "111", "password": "as"},
  "user2": {"username": "222", "password": "ad"},
  "user3": {"username": "A320098207", "password": "Cszxqc@2022"}
}
@file_data("E:\demo-selenium-pytest\data\login2.json") #json
def test_run_g2(self, username, password):  # 会生成2条用例
    print(" test_run_g2:"+username+" "+password)
#. test_run_g2:111 as
#. test_run_g2:222 ad
#. test_run_g2:A320098207 Cszxqc@2022

- 传yaml文件：
user1:
  username: "111"
  password: "as"
user2:
  username: "222"
  password: "ad"
user3:
  username: "A320098207"
  password: "Cszxqc@2022"
@file_data("E:\demo-selenium-pytest\data\login.yaml")  #yaml
def test_run_g3(self, username, password):  # 会生成2条用例
    print(" test_run_g3:" + username + " " + password)
#. test_run_g3:111 as
#. test_run_g3:222 ad
#. test_run_g3:A320098207 Cszxqc@2022

- 传txt文件：
111,as
222,ad
A320098207,Cszxqc@2022
def readtxt():
    params = []
    file = open("E:\demo-selenium-pytest\data\login3.txt", "r", encoding="utf8")
    for line in file.readlines():
        params.append(line.strip("\n").split(","))
    return params
@ddt
class test_query_userinfo2(unittest.TestCase):
    @data(*readtxt())  #txt
    @unpack
    def test_run_h(self, username, password):  #
          print(" test_run_h:" + username + " " + password)
#.EE test_run_h:111 as
#. test_run_h:222 ad
#. test_run_h:A320098207 Cszxqc@2022
