How to get the response in different format in Mock Server using Postman?
We can get the Response in different formats in Mock Server. A Mock Server is created to avoid sending requests on the real time or production data. The steps to create a Response in different format in Mock Server are listed below −Step 1 − Click on New from the top of the Postman application. Then click on the Mock Server link.Step 2 − Choose the option GET from the Method field. Add /user/home in the Request Path, 200 in Response Code and the text – This is Postman Tutori in Tutorialspoint in the Response Body field.Step 3 − Provide ...
Read MoreHow to Import Collection in Postman?
We can import Collections in Postman. To perform the this task, follow the below steps −Step 1 − Click on the Import menu in the Postman application.Step 2 − Import pop-up shall open with the options to import from a File, Folder, Link, Raw text and Code Repository.Step 3 − We can either import by clicking on the Upload Files button or by drag and drop option. From the Code repository tab, we can import from GitHub.
Read MoreHow to set Test and Collection Runner in Postman?
We can add test verifications to the Response obtained from a request with the help of scripts. These scripts are incorporated in the Tests tab. The tests only get executed provided the request is successful.A test developed under the Tests tab is written in JavaScript. Once a request is sent, a Response is obtained along with the test results in the Test Results tab. Tests which have passed are marked in green and the failed ones are marked in red.Add the below JavaScript verifications within the Tests tab −tests["Status Code should be 200"] = responseCode.code === 200 tests["Response time lesser ...
Read MoreDifferent types of Asserts in Postman
There are different types of Asserts in Postman. We can add Assertions on different sections of the Response received. Some of the Assert types are listed below −Assert on Response Codepm.test["Status Code is 200"], function(){ pm.response.to.have.status(200) })The above assertion passes if the Response code is 200.pm.test["Status is OK"], function(){ pm.response.to.have.property('status', ' OK') })The above assertion is applied on the Response property – status with value as OK.Assert on Response timepm.test("Response time below 600 milliseconds", function () { pm.expect(pm.response.responseTime).to.be.below(600) })The above assertion passes if the Response time is below 600ms.Assert on Response Formatpm.test("Response is of JSON type ", ...
Read MoreExecuting Tests on Cookies in Postman
We can execute Tests on Cookies in Postman. Once a request gets executed for an endpoint, a Response gets generated. Within a Response, the cookie information gets generated under the Cookies tab.We can add Tests script around cookies and apply Assertions on them for verification. Test scripts are incorporated under the Tests tab. Let us add the below script to verify the value of cookie – Cookie_Postman.pm.test("Verify Cookie value", function(){ pm.expect(pm.cookies.get('Cookie_Postman')).to.eql('value1')})Send the Request. After the Response is received, navigate to the Tests tab. It shows the Assertion in our Test script failed as the expected value of the Cookie_Postman is ...
Read MoreHow to handle Infinite loops in Postman Workflow?
We can handle infinite loops in the Postman workflow. The requests in a Collection get executed in the order in which they appear. However, we can change the workflow with the help of the function - postman.setNextRequest().It is used to direct the next request to be executed. The name of the next request to be executed is passed as a parameter to this function.Syntax postman.setNextRequest("next request name")Let us take an example of a Collection having four requests -We would like Postman to change to a workflow such that the below requests are executed from top to bottom in the order listed ...
Read MorePractice Questions on Time Complexity Analysis in C++
Time complexity of any algorithm is the time taken by the algorithm to complete. It is an important metric to show the efficiency of the algorithm and for comparative analysis. We tend to reduce the time complexity of algorithm that makes it more effective.Example 1Find the time complexity of the following code snippetsfor(i= 0 ; i < n; i++){ cout
Read MoreArduino Time Library Introduction
The Time library provides you with timekeeping functionality on the Arduino. The latest version of the library is documented here.To install it, search for Time in the Library Manager and install the library by Michael Margolis.You’ll have to scroll a bit to find this library.Once the library is installed, if you go to File → Examples → Time, you will be able to see several examples of integrating this library with various sources: GPS, NTP, RTC, etc.The basic idea is that you can set time using the functions −setTime(hours, minutes, seconds, days, months, years);OR, setTime(t);where t is the special time_t ...

Read MoreReference and dereference operator in Arduino
The reference (&) and dereference operators (*) in Arduino are similar to C. Referencing and dereferencing are used with pointers.If x is a variable, then its address is represented by &x.Similarly, if p is a pointer, then the value contained in the address pointed to by p is represented by &p.Examplevoid setup() { // put your setup code here, to run once: Serial.begin(9600); Serial.println(); int x = 10; int *p; p = &x; //p now contains the address of x Serial.print("The value stored in the address pointed by p is: ");Serial.println(*p); } ...
