Interface Test-parse the har File

Interface Test-parse the har File

Previously, I have studied how to obtain the har file required by our tool in different ways for business testing. Now we have obtained the har file provided by business testing, first, we need to parse the information stored in these files, especiallyentriesField Information, In the omnipotentgithubI found a toolkit.

Address

Har

Because this jar package is not available for download in the maven repository, You need to download the source code to your local computer, package it, and upload it to your own private repository for other developers to download.

Source code

The main class isHarUtils.java, There are two classes required for execution under the command line (HarCli.java,ViewHar.java). For the main functions of these two classes, please refer to my previous article Java command line program build tool-airline. The last thing left is the entity classes in the model package, which correspond one by one.harObject.

Provides the following methods to obtainHarObject:

Method	Explanation
Read (File)	Generate the har object with the har file as the parameter
Read (JsonElement)	Take the JsonElement object as the parameter
Read (Reader)	Get har object from byte stream
Read (String)	Get har object from string
ConnectReferences (Har har)	Associate pages in the pages and enties fields in the har File

Instance

public class HarParserTest {    @Test    public void parserFile() throws Exception {        File file = new File("/Users/wuxian/Desktop/interface/www.baidu.com.har");        Har har = HarUtils.read(file);        System.out.println("HarParserTest.parserFile() : " + har.toString());    }}

Summary

We get the Har information, and we can do a lot of work. We use the har file to parse all URLs and parameters so that we can get a batch of interface information. So what can we do? Wait for the future.
