Test Development - ten years of sharpening one sword (VII) interface test tool postman

Before contact interface test , I used a tool called Fiddler, It's a very good Web Debugging tools , It can record all client and server's http and https request , Allow you to monitor , To set breakpoints , Even modify input and output data . For example, you monitor Baidu's search interface , Set breakpoints before sending the request , Modify the contents of the query parameters when the breakpoint takes effect , Then send the request , The returned response is the search result for the modified content .

It took a while HttpClient after , The code doesn't want to be maintained , So I learned to use PostMan and JMeter Used for interface testing .

PostMan Used to be Google Chrome A powerful plug-in for , Later, it became an independent client , The function is also more powerful and perfect , Newer versions of UI Here's the picture .

PostMan The primary use of is also very simple ：

1. In the figure Post Location , selection http Request type , frequently-used Post,Put,Get etc. .

2. URL, Generally, only fixed url, Parameters are not included , Of course, you can also fill in , But there is no next item Params clear .

3. Params, To configure URL Parameter information in , Please refer to Baidu search results page for details URL, It will contain the search content you entered ;

4. Authorization, If the interface needs authentication , You need to fill in the corresponding parameters ;

5. Header, Requested header Content , There are default parameters , You can also modify , Or add custom header;

6. Body, Request incoming data , It's usually json Format .

7. Pre-request, A simple code base is needed here to begin , The script can dynamically set the parameters of this request or other custom operations .

8. Tests, Assertions can be added to this script , Judge whether the response is correct , Eliminate the steps of human verification .

above , yes PostMan The basic application of the newer version , Then click execute , Just view the response results .

Of course , From its UI You can see the function module icon on the left ,PostMan My ambition is still great , such as Mock Service Can provide the server Mock function , Provide interface instead of uncompleted function , For testing ;Monitor Provide detection function , It can reflect interface performance index, etc .

PostMan I don't use much , Just verify the interface functionality , Don't make a fool of yourself about other functions .
