Pytest learning ----- pytest operation mode and pre post packaging of interface automation testing

One 、Pytest Advantage cognition ：

1. It can combine all automated testing tools
2. Skip the failure case and rerun the failure
3. combination allure Production aesthetics report
4. and Jenkins Continuous integration
5. Many powerful plug-ins

 pytest-html： production html Test report 
 pytest-xdist： Multithreading 
 pytest-ordering： Change the order of use case execution 
 pytest-rerunfailures： Failed case re crawl 
 allure-pytest: Aesthetic test report 

In general projects , Will use requerments.text Document save plug-in name , Carry out batch one-time installation

pip install -r requerments.txt

Two 、 Operation mode ：

1. Operation mode of main function ：main Method run
2. Command operation mode
pytest -vs
-v： More details
-s： Debugging information
-n= Handle ： Multithreading
--reruns= Numbers ： Failed use case rerun
--reruns= Numbers ： Failed use case rerun
--html=./report.html： Generate html The report

Use cases run in groups

1. Group use cases ：
2. Use cases are annotated ：

#@pytest.mark. Group name    as follows ：

@pytest.mark.smoke

[pytest]
## Run the command , for example ： -vs -m "smoke" Group execution names are fixed 
addopts = -vs 
# Test case file directory 
testpaths = ./testcases
python_files = test_*.py
python_classes = Test*
python_functions = test_*
## grouping 
markers =
    smoke:maoyan
    case:gongneng

3、 ... and 、 Front and back , fixture

1. Simple distinction ： Direct call method , But when there are too many interfaces , More trouble

    def setup(self):
        print(" Before each use case is executed , Do it all once ")
    def teardown(self):
        print(" After each use case is executed , Do it all once ")

2. Realize partial pre ： If you only want one use case to precede , For example, you need to connect to the database when logging in .

You need to use a device ：

Parameter Introduction ：

@pytest.fixture(scope=" Scope ",params=" Data driven ",autouse=" Whether to execute automatically ",ids=" Custom parameters ",name=" rename ")
Scope ： Can function 、 class 、 modular 、 package 、session

Usage method ：

1. The device needs to be labeled on the pre-set function
2. Call the device between other methods and functions

as follows ： Some pre wakeups are performed in a file

import time

import pytest
import requests
# Implement device label pre , Annotate ,yieid Wake up and return 
@pytest.fixture(scope="function")
def conn_getbase():
    print(" Successfully connected to database ")
    yield
    print(" Closing database succeeded ")

class TestSendRequsets:
    # When there are too many interfaces , It is troublesome and redundant 
    # def setup(self):
    #     print(" Before each use case is executed ")
    #
    # def teardown(self):
    #     print(" After each use case is executed ")

    def test_getImgCode(self):
        #  Interface url
        t = time.time()
        timess = str(int(round(t * 1000)))
        times = str(int(t))
        url = "http://124.71.230.185:9002/jeecg-boot/sys/randomImage/" + "" + timess
        #  Parameters 
        data = {
            "_t": times,
        }
        # # get request 
        rep = requests.request('get', url, params=data)
        print(rep.text)

    #  Tagged as smoke Group use cases 
    @pytest.mark.smoke
    def test_Login(self,conn_getbase):
        # post request 
        url = "http://124.71.230.185:9002/jeecg-boot/sys/login"
        #  Parameters 
        data = {
            "captcha": "[email protected]#2021",
            "checkKey": 1637811815838,
            "password": "123456",
            "remember_me": 1,
            "username": "admin"
        }
        rep = requests.request('post', url, json=data)
        statues = rep.json()["success"]
        message = rep.json()["message"]
        if statues:
            print("")
        else:
            # raise Exception(message)
            print(message)


if __name__ == '__main__':
    pytest.main();

3. Encapsulate flexible calls

In general ：@pytest.fixture() Hui He conftest.py Use files together

conftest.py The name is fixed , Function as follows ：

1. There are many uses py Share pre configuration between files .
2. When the method inside is called , No need to import , Can be called between
3. You can have more conftest.py file , There can also be different levels

conftest.py For details of the document, please see the next chapter

Realization ：

1. Create between directories conftest.py file
2. Paste the above code into conftest.py In file

#  Pre function 
import pytest

@pytest.fixture(scope="function")
def conn_getbase():
    print(" Successfully connected to database ")
    yield
    print(" Closing database succeeded ")
