Talking about interface test (2)

2022-06-26 01:40:00 【NitefullSand】

1. Type of interface test

It mainly includes three kinds of tests ：

  1. Web The interface test ,
  2. Application program interface （API, application programming interface） test ,
  3. Database test .

In fact, the meaning is UI Interface to database , All the processes that the data flow goes through .

1、LAMP（Linux Apache MySQL PHP）/LNMP（Linux Nginx MySQL PHP）： Only Web The server , No application server ：

  • Web browser To Web The server ： Web The interface test , test Requests and responses .
  • Web The server To database server ： Application interface test , test PHP.

2、Linux / Windows + Java / Asp.net(C#) + Apache/Nginx + Tomcat/IIS + MySQL/Oracle/SQL server

  • Web browser To Web The server ： Web The interface test , test Requests and responses .
  • Web The server To application server ： Contractual services ,WebService,JavaAPI,WebAPI,WCF,.net Remoting： test Java perhaps C# Process business logic （JavaEE/ ASP.NET MVC）, Generally speaking, testing Service.
  • application server To database server ： Data processing services , test Java perhaps C# Processing data , Read the data into the database .

Here's what we need to focus on Web The interface test .

Web Method of interface test ：

  • Python perhaps Java,C# Programming , Trigger request , Read response , Analyze the response data and compare with the source data .
  • With tools ：Postman perhaps SoapUI（ Not recommended ）

Postman It was originally a Chrome Browser plug-ins , Now... Has been provided Windows、MacOS and Linux A standalone installation of . Next use Windows To install and use .

2. Postman Installation

  1. download Postman Installation package , It is divided into 32 position and 64 position .https://www.getpostman.com

  2. install Postman

  3. Registered users (Sign Up) And login (Sign In)

    Snap23.png

  4. You can log in from multiple computers , The tests done will be synchronized automatically .

    Snap24.png

  5. After installing and logging in, you can start testing .

    Snap25.png

3. Web Test point of interface

Web Interface by HTTP(S) request , It's a URL,URL Request the results , You get the data , There are two main data formats , A kind of JSON, A kind of XML. It mainly uses JSON demonstration .

  • JSON, yes JavaScript Object Notation,JavaScript Object notation . It's used to show JavaScript The object of , perhaps JavaScript Data etc. . because JavaScript Widely used in Web Front page of , therefore JSON Mainly used in Web Interface . Main application scenarios ：
    • APP Communication between mobile terminal and server . Use the application layer HTTP agreement , adopt Web Interface reads data and processes （ Submit ） data .
    • Web Communication between the front end and the server , Often the server is a third party , The main scenario is Payment and third party login .
      • JD.COM web End call Wechat payment 、 TenPay pay 、 Alipay pay 、 UnionPay payment 、 E-currency payment ...
      • JD.COM web End Support Wechat login 、QQ Sign in 、 Micro-blog login
      • JD.COM web End Show Third party logistics information （ Shun Feng 、 sto 、 Tact ...）
      • Public data , stay web End /APP End of the weather forecast 　 It is provided by a third-party interface .
  • XML,Extensible Markup Language, Extensible markup language ,HTML Namely XML A form of , adopt Pairing of labels , And the hierarchy of labels , To determine the content of the data .XML Mainly used in the backend Data transfer of application program interface , such as Java,C# etc. .XML Older formats .

Let's use an example , To separate JSON and XML Represents the following tabular data .

employee_idfirst_namelast_nameemailphone_numberhire_datejob_idsalary
100StevenKingSKING515.123.45676/17/1987AD_PRES24000
101NeenaKochharNKOCHHAR515.123.45689/21/1989AD_VP17000

First use JSON In the form of ,JSON yes “ Key value pair ”（Key Value） In the form of

 

{
  "employees": [{
    "employee_id": 100,
    "first_name": "Steven",
    "last_name": "King",
    "email": "SKING",
    "phone_number": "515.123.4567",
    "hire_date": "6/17/1987",
    "job_id": "AD_PRES",
    "salary": 24000
  },
  {
    "employee_id": 101,
    "first_name": "Neena",
    "last_name": "Kochhar",
    "email": "NKOCHHAR",
    "phone_number": "515.123.4568",
    "hire_date": "9/21/1989",
    "job_id": "AD_VP",
    "salary": 17000
  }]
}

Corresponding XML Format ：

 

<?xml version="1.0" encoding="UTF-8" ?>
<employees>
    <employee>
        <employee_id>100</employee_id>
        <first_name>Steven</first_name>
        <last_name>King</last_name>
        <email>SKING</email>
        <phone_number>515.123.4567</phone_number>
        <hire_date>6/17/1987</hire_date>
        <job_id>AD_PRES</job_id>
        <salary>24000</salary>
    </employee>
    <employee>
        <employee_id>101</employee_id>
        <first_name>Neena</first_name>
        <last_name>Kochhar</last_name>
        <email>NKOCHHAR</email>
        <phone_number>515.123.4568</phone_number>
        <hire_date>9/21/1989</hire_date>
        <job_id>AD_VP</job_id>
        <salary>17000</salary>
    </employee>
</employees>

Web The definition of the interface determines the test content

  1. Method：GET POST PUT DELETE
  2. URL: The address of the interface
  3. Request parameters ： Each parameter name , Type of parameter , The range of parameters , Is the parameter optional , Whether the parameter has a default value
  • Equivalence class ： Valid equivalent parameters , Invalid equivalent parameter
  • The boundary value ： Departure point , Upper point , Inside point
  • Orthogonal test method ：× factor × state
  • sometimes , Association between parameters ： province , City , county （ District ）, Pay particular attention to illegal （ Invalid ） The associated
  1. Assertion ： Check the contents of the response
  • Text ： Whether the body contains some characters
  • Text ：JSON perhaps XML Key value pair check for , Quantity check xx.length
  • The status code of the response ：200, 403
  • Response time : 100ms, 200ms
    *5. authentication ： Do you have access to the interface

  1. The actual object of the interface ： data

    1. The format of the data
    2. Content of data

    ​

4. Postman Use

  1. test Knowing weather API：https://www.seniverse.com/

5. Web Interface authentication

Web Preparation of interface test

  1. HTTP Protocol request and response
    request ：GET/POST
    Respond to ：html/JSON/XML/CSS/JavaScript/png..
  2. The concept of testing
    Assertion ： Check the contents of the returned response .
    Test design ： Design the use case according to the requested parameters
  3. Read the interface documentation
    The way of request and URL
    Request parameters and response parameters
  4. Use authentication when requesting interfaces
    basic authorization Basic certification , Enter your username and password

On the basis of the above four , Be careful Web The interface needs authentication , Especially the payment business , Here is an example , And is POST request + Basic Auth authentication , To illustrate this part .

Steps of the example ：

  1. open https://www.pingxx.com/ Ping++ Online payment website , Create an account , And login , An application will be created automatically .

    Snap27.png

  2. Enter the automatically created application , Enter the application control panel interface .

  3. obtain APP[id], Get... As shown in the figure , And use it later

    Snap28.png

  4. obtain Test Secret Key, Get... As shown in the figure , And still wait to use

    Snap29.png

    Snap30.png

  5. Follow the steps below , Look up API file , And start testing .

    Snap31.png

     

    Snap32.png

     

    Snap33.png

  6. choice Charge, Create a Payment order , Look up API Request parameters of the document , Response parameter , still Methods and URL

    Snap34.png

  7. stay Postman Create a new test in , Input POST and URL

    Snap35.png

  8. Set parameters , You need to use APP[id], Obtained for the previous step .

    Snap36.png

  9. stay Use... In request authentication ,Basic Auth, Input Obtained in the previous steps Test Secret Key, As user name .

    Snap37.png

     

    Snap38.png

  10. Add test assertions .

use JavaScript Script , Inquire about JSON The value of the object , And check . Click on the ready-made menu on the right , Checks are automatically generated JSON Framework .

 

var jsonData = JSON.parse(responseBody);
tests[" Check object value "] = jsonData.object === "charge";
tests[" Check order_no value "] = jsonData.order_no === "99887766554433221100";
tests[" Check amount value "] = jsonData.amount === 9900;

​

  • Example 2： Create a red envelope Web The interface test

  1. Interface description of wechat red packet payment interface test

    Create a red envelope Web Interface description

  2. stay Postman Input in POST Methods and URL

    Paste_Image.png

  3. stay Postman in Use Http Basic Auth authentication . Enter the previously obtained Secret_test_key. according to API Operations performed by the document

    Paste_Image.png

    stay Postman In the operation

    Paste_Image.png

    Paste_Image.png

  4. Input Requested parameters , Be careful POST Requested request parameters , Input to Body in

    ​

    enter text

  5. stay Test Set assertion , Just now I said to set Object Validation of the .

    Enter the following ：

    Assertion 

    var jsonData = JSON.parse(responseBody);
tests[" Check  Object  attribute "] = jsonData.object === "red_envelope";
tests[" Check   amount of money   attribute "] = jsonData.amount === 6000;

    ​

  6. Click on Send, Check .

    result

  7. Go to the management platform to view the order results .

    Paste_Image.png

6. Postman Other functions of

Postman Support the export of use cases and the synchronization of accounts .

Snap41.png

7. Python requests Use

Postman As a tool , Yes UI The tool can be operated completely Web API（Application Programming Interface）, Some scenes , You also need to operate in an automated test scenario Web API. about Python There are two main tool operations HTTP Web API.

  • urllib （python Self contained , But grammar is anti human ）
  • requests （ A third party , however HTTP Request for human), We recommend this requests Tools .

and Selenium equally ,requests It is also a third-party tool library . analogy Selenium Operating the browser ,requests operation HTTP request .

Deploy requests The process of

 

pip install requests

requests There are two common ways

  1. requests.get()
  2. requests.post()

Both of the above methods will return one Response Class object . Be careful Response class Belong to requests.

As an automated interface testing tool , Be similar to Selenium, We need to use Page-Object How to design

  • Every Page Write a URL The function of .
    • get_realtime_weather_by_ip
    • get_realtime_weather_by_city
    • get_realtime_weather_by_location
    • ... Company
    • ... Language
  • Every page Not at all Direct use requests
    • encapsulation requests To box_requests.py
    • Create a class , Used to remove from the package box_requests.py Return to our customized result （ Respond to ）
  • In each use case , Inherit unittest.TestCase, call Page, To test
    • The test data should be extracted , Put it in csv perhaps In the database

8. ordinary GET Request instance

  • The weather is real

GET/weather/now.json

Get the weather of the specified city . Paying users can access all data , Free users only return the weather phenomenon text 、 Code and temperature 3 Data . notes ： Chinese cities do not support cloud cover and dew point temperature .

Request address example

Specific steps ：

  • encapsulation requests To box_requests.py

    import requests
from model.http_response import HttpResponse

class BoxRequests:

 according to  Postman  Execution of this test . Select the following data ：

- headers
- data：params

 Put the above two data , become Python  The dictionary is passed to  requests.post()  in ,

 Check... In the resulting response  Json  The value of the object .

1.  modify  box_requests, add to  post_json Method 

   ```python
   def post_json(self, url, data=None, json=None, **kwargs):
       """
            use  POST  Method request for  URL
           :param url:
           :param data:  Data submitted 
           :param json:  The submitted  json （ Optional ）
           :param kwargs:  Additional parameters 
           :return:
           """
       r = requests.post(url, data, json, **kwargs)
       http_response = HttpResponse()
       http_response.status_code = r.status_code
       http_response.json_dict = r.json()
       return http_response

  1. establish page, Serve test cases 

    class PingxxChargeCreatePage:
    base_url = "/charges"

    def create_charge(self, host, data, headers):
        br = BoxRequests()

        #  use  host  and   overall situation  base_url  Piece together  URL
        http_response = br.post_json(host + self.base_url,
                                     data=data,
                                     headers=headers)
        return http_response

    ​

  2. establish test_case

    import unittest

class PingxxApiTests(unittest.TestCase):
    test_secret_key = None
    app_id = None
    page = None
    host = None

    def setUp(self):
        self.app_id = "app_rfv1SGmPKijLnPef"
        self.test_secret_key = "c2tfdGVzdF80bXpqelRpenpQQ0NqVEt5VEN5VGVqYlA6"
        self.host = "https://api.pingxx.com/v1"
        self.page = PingxxChargeCreatePage()

    def test_create_charge_by_wechat(self):
        data = {
            "order_no": "88888888666666664444444422222222",
            "app[id]": self.app_id,
            "channel": "wx",
            "amount": 10000000,
            "client_ip": "192.168.1.202",
            "currency": "cny",

        headers = {"Authorization": "Basic %s" % self.test_secret_key}

        r = self.page.create_charge(self.host, data, headers)
        self.assertEqual(200, r.status_code, " The status code returned incorrectly ！")
        expected_object = "charge"
        actual_object = r.json_dict["object"]
        self.assertEqual(expected_object, actual_object, " Check whether the object is payment failed ！")
