1. Parametric processing

A parameterized ： For an interface , There are a large number of test data that need to be verified in batch , Changing request parameters one by one is too time-consuming and labor-consuming , It is more efficient to use parameterized batch data processing , The general implementation is through document parameterization .

The first line of information in the file It needs to match the parameter variable

Batch execution Insert picture description here

Parameterized assertion
Add assertion data

//  Set a variable assert
assert = pm.variables.get("assert");
//  break   said  message  word   paragraph   value   by  success 
pm.test("message The field values for success", function () {
    
var jsonData = pm.response.json();
 pm.expect(jsonData.message).to.eql(assert);
});

2. Postman Generate test reports

Postman Use runner Runtime , The generated report can only be in Postman Inside view , It's not very convenient . So you can generate a HTML The report , Open it through the browser

Postman Need generation HTML Reports need to use newman, With the help of newman Tool generation .

2.1 install newman

newman It's using node.js Development , Specially for postman A tool plug-in for generating test reports . We need to install node.js、newman、newman plug-in unit ：newman-reporter-html

download node.js：https://nodejs.org/en/ Proposed installation 15 perhaps 16 edition

npm install -g cnpm –

registry=https://registry.npm.taobao.org install newman: open cmd, Input npm install -g newman

install newman-reporter-html open cmd, Input npm install -g newman-reporter-html

2.2newman The command runs the use case

newman run Use case set .json -e Environmental documents .json -d Data files .json -r html --repoter-html-export report.html

newman run Use case set .json The meaning of running a use case set

-e Environmental documents .json Specify the running environment

-d Data files .json Specify the data to run

-r html Generate html The report

–reporter-html-export report.html Appoint html Report name is report.html

You need to export the script before execution / Data files / Environment files such as ：

newman run token.postman_collection.json -d logindata.txt -e pinter project .postman_environment.json -n 3 -r html --reporter-html-export .\
