1、 Preface

　　 When I haven't actually done interface test before , The concept of interface testing is rather vague , Only Baidu , View various interface instances , And then it doesn't work , Now, all kinds of interfaces are lost , Finally, I have a practical understanding . Because it's just a functional test of the interface , So now it's using postman Do a test , It's easier , Of course, this is just the beginning of interface testing , It's just the tip of the iceberg , In the future, efforts will be made to interface pressure 、 Interface performance 、 Interface automation is moving closer .

2、 Interface theory

　　 We often say that the interface is API, Interface test is a test to test the interface between system components . The interface test is mainly used to detect the interaction points between the external system and the system as well as between the internal subsystems . The focus of the test is to check the exchange of data , Transfer and control the management process , And the mutual logical dependence between systems .

　　 In fact, interface testing is no different from normal function testing , The difference is that the function test is to enter values on the page , Submit the data to see the result , And interface tests don't have pages , Specify the call address on the document through the interface , Request parameters , Splicing message , Then send the request , Check the return result .

                            

 

3、 Interface instance

One 、POST

POST Requests are used to send data , Below XX For example, the system allocates processing plants

1、 Product manager's PRD The documentation requirements are as follows （ Modify the interface of the distribution processing plant as follows ）：

1） New factories are added in the interface of distribution processing factory ID Field , Integer types , Not required ;

2.） If the picking list has been approved , Limit the allocation of processing plants only in the status to be audited , If not, remind “ Picking list is not to be approved , Can't allocate processing plants ”;

2、 The developer's interface documentation is as follows ：

The name of the interface ：XX The system allocates the factory interface

Interface path ：POST
/process/requisitionOrder/updateDistributeStatus

Request parameters ：

Headers：

Body：

{
  "factoryId": "123",// Processing factory ID
  "factory": "XX dress ",// Name of processing plant 
  "produce_order_id": [// Production and voucher making （ Pure number ）  Multiple use , Separate 
    1134360
  ]
}

Return the data ：

{
  "msg": "success",
  "code": "0",
  "info": " Successful operation "
}

3、 The tester's test cases are as follows ：

4、 The tester performs the test cases as follows ：

1） open Postman, Fill in the interface information , The specific operation is shown in the figure

notes ： In the interface document URL No environmental address , So will URL When copying to the address bar , Add the address of the environment , For example, the address of the test environment + Interface URL,

Of course, if there are multiple environments , You can use the environment to configure functions , The specific configuration steps are in 4） Step by step .

2） Combine test cases , After combining and transforming the parameter information , Check back JSON Data and PRD Is it consistent

3） After the test case traversal is complete , That's it POST Interface function test requested .

4） Here's a description of postman Environment configuration of

First step , Pictured

The second step , Pictured

The third step , Pictured

Step four , Pictured

Step five , Pictured （ This is for situations with multiple environments , For example, there are usually test environments 、 Acceptance environment 、 Production environment ）

Two 、GET

GET Requests are used to get data , Let's say XX For example, the system obtains the delivery bill ,（ Only some data information is listed below for demonstration ）

1、 Product manager's PRD The documentation requirements are as follows ：

2、 The developer's interface documentation is as follows ：

The name of the interface ： Synchronize the delivery bill to XX system interface

Interface path ：GET
/purchase/prepareOrder/importListFromPlm

Request parameters ：

Query：

Return the data ：

{
    "msg": "success",
    "code": "0",
    "info": {
        "list": [
            {
                "billNo": "ML201902205005",         // Bill number 
                "billDate": "2019-02-20",           // Bill date 
                "factory": " The production department of sarvan clothing - Ye Lin ",   // Name of supplier 
                "materialSku": "16MLZS0513-628",    // materiel SKU
                "num": 20,                          // Number 
                "purchasePrice": 0,                 // Purchase unit price 
                "billSum": 0,                       // The amount of the bill 
            }
        ]
    }
}

3、 The tester's test cases are as follows ：

4、 The tester performs the test cases as follows ：

1） open Postman, Fill in the interface information , The specific operation is shown in the figure

notes ： In the interface document URL No environmental address , So will URL When copying to the address bar , Add the address of the environment , For example, the address of the test environment + Interface URL,

Of course, if there are multiple environments , You can use the environment to configure functions , For specific configuration steps, please refer to POST Description of

2） Combine test cases , After combining and transforming the parameter information , Check back JSON Data and PRD Is it consistent

3） After the test case traversal is complete , That's it GET Interface function test requested

 

 

Thank everyone who reads my article carefully ！！！

If you can use the following information, you can take it away directly ：

1、 Self study development or test the necessary complete project source code and environment

2、 Test all templates in the work （ test plan 、 The test case 、 Test report, etc ）

3、 Classic interview questions for software testing

4、Python/Java Automation test practice .pdf

5、Jmeter/postman Interface test full set of video acquisition

I personally sorted out some technical materials I have sorted out in my software testing career in recent years , contain ： e-book , Resume module , Various work templates , Interview treasure , Self study projects, etc . Please leave a message in the comment area. Thank you .
