Automated testing -- Introduction and use of pytest itself and third-party modules

pytest-html Test report

 install ：
 :pip3 install pytest-html
 
 send ⽤⽅ type ：
 1. command ⾏⽅ type 
 2. To configure ⽂ Pieces of ⾥
 
 command ：
 --html=⽣ Report path / Report name .html
 --junitxml=⽣ Report path / Report name .xml
 
 Should be ⽤：
  command ⾏
 pytest --html=xx.html
 #  At present ⽬ record ⽣ become xx.html⽂ Pieces of 
 pytest --html=./report/result.html
 #  At present ⽬ Recording meeting ⾃ Create report⽂ Clip ,⽂ In clip ⽣ become result.html
 #  Be careful ： There must be no spaces on either side of the equal sign 

pytest-rerunfailures Failure to retry

 install ：pip3 install pytest-rerunfailures

 send ⽤⽅ type ：
  command ⾏
  To configure ⽂ Pieces of 
 command ：--reruns n (n: The number of retries  ) 

  Be careful ： The retry plug-in cannot be connected with setup_class⼀ Start to make ⽤,⾮ The first ⼀ One test ⽅ The law failed , There will be logical errors 

↑↑↑ The above two configuration files refer to ↑↑↑：

[pytest] # command line
addopts = -s --html=./report/res.html --reruns 2 # search dir
testpaths = ./scripts
# search file
python_files = test_rerun_pro.py
# search class
python_classes = Test* # search functions
python_functions = test*

pytest-ordering Control the execution of the test function ⾏ The order ：

 install : pip3 install pytest-ordering

 send ⽤：
 @pytest.mark.run(order=x)
 
 x: All positive or all negative numbers , Value more ⼩, The test of embellishment ⽅ The higher the priority of the law ⾼
 x: When both positive and negative numbers exist , Positive number modification test ⽅ Law priority ⾼
 x: by 0 when , Highest priority ⾼
 x: When it's negative , The priority is lower than the undecorated test ⽅ Law 
 x: A positive number is , priority ⾼ Apply to undecorated tests ⽅ Law 

Skip the test method ：

@pytest.mark.skipif(condtion, reason) #  send ⽤ There are fewer scenes 
 condtion: Required 
 reson： Required 
 Combine ：
 1. Condition is True+ There's a reason   Of board ⾏ skip 
 2. Condition is False+ There's a reason   Do not cling to ⾏ skip 
 3. Only reason   Also hold on to ⾏ skip 
 4.⽆ Conditions +⽆ reason   Also hold on to ⾏ skip 
 5. Only the conditions   newspaper error error 

Of board ⾏ Expected failed operation ：

@pytest.mark.xfail(conditon, reason) #  send ⽤ There are fewer scenes 
condtion: Required 
reson： Required 

 Be careful ： Expected failure ⽅ The Dharma Council acquiesces in ⾏⼀ Secondary test ⽅ Law 

 Combine ：
1. Condition is true + There's a reason   Of board ⾏ Expected failure 
2. The condition is false + There's a reason   Do not cling to ⾏ Expected failure 
3.⽆ Conditions  +  There's a reason   Of board ⾏ Expected failure 
4.⽆ Conditions  + ⽆ reason   Of board ⾏ Expected failure 
5. Conditional  + ⽆ reason   newspaper error abnormal 

 Expected failure ⾏ result ：
1. test ⽅ The law itself breaks ⾔ adopt , result  xpassed
2. test ⽅ The law itself breaks ⾔ Failure ,  result  xfailed

parametrize A parameterized ：

#  Single parameter 
 @pytest.mark.parametrize(" Parameters ", [ Parameter values 1, Parameter values 2, Parameter values 3])
  result ：
 ⽅ FA Huiyun ⾏ list ⻓ degree 
 Code 
import pytest
class Test_001:
	#  Traverse the parameter value list ,⽅ Law movement ⾏ frequency  =  list ⻓ degree 
	@pytest.mark.parametrize("data", [1, 2, 3, 4])
	def test_001(self, data): # paramtrize Parameter name = test ⽅ Method parameter name , The name must be ⼀ Cause 
	""" Judge the value in the list   It's not equal to  2"""
	print("\ndata:", data)
	assert data != 2

#  Multiple parameters 
@pytest.mark.parametrize(" Parameters 1,  Parameters 2", [( Parameters 1 value , Parameters 2 value ),( Parameters 1 value , Parameters 2 value )....])
 Code ：
 import pytest
 class Test_002:
 	#  Multiple parameters in ⼀ In strings 
	 #  test ⽅ The position of method parameters can be changed 
	 # parametrize Middle parameter name   Must be equal to   test ⽅ Method parameter name 
	 @pytest.mark.parametrize("a,b,c", [(1, 2, 3), (3, 4, 5), (5, 6, 11)])
	 def test_002(self, a, b, c):
	 """ The sum of two numbers is calculated  a+b == c"""
	 print("\na:", a)
	 print("\nb:", b)
	 print("\nc:", c)
	 assert a + b == c
