Analysis of postman core functions - parameterization and test report

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 .

• create a file Format CSV

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

• Batch execution

• 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);
});
