Postman data driven

One 、 What is data driven

         The process of executing test cases , Essentially different data for execution , Different input and output processes . We can use preset data files , To execute test cases , Achieve coverage of test points .

Two 、postman Data driven steps

scene ： Multiple users log in at the same time

Step one ： Data preparation , The data to be entered is usr,expect

postman Can be used in the csv perhaps json Format

①csv The format is as follows ：

 ②json The format is as follows ：

Step two ： Create test set

Step three ： Create an interface , Fill in URL、 Parameter data ,username Request parameters to get the incoming data { {usr}}

Step three ： stay Test Add assertion in , There are two assertions here , Status code and user name

perhaps ：

//  Verification status code

pm.test(" Status code for 200", function () {

    pm.response.to.have.status(200);

});

 // Verify the user name in the returned data

pm.test(" The user name is correct ", function () {

    var jsonData = pm.response.json();

    pm.expect(jsonData.username).to.eql(data.expect);// Verify that the returned data is consistent with that in the data file

});

Step four ： Execute test set

Step five ： View the run results
