Troubleshooting Postman issues Preview 05:19

So the API you are calling is not working? Don’t panic and keep calm because in this lecture I will show you a couple of tips on how to troubleshoot the most common problems in Postman.

Working with API requests

In this assignment I have prepared a couple of tasks for you to solve.

How to import a request from your browser in Postman Preview 02:44

This video will show you how to easily create Postman request by importing them directly from your browser.

Introduction Preview 00:39

In this section your are going to start writing tests but at the same time explore more features of Postman such as variables and environments for adding a dynamic behaviour to your requests, workflows and scripts for more advanced scenarios.

The Postman Cheat Sheet & Quick Reference Guide Preview 00:14

Your first API test in Postman Preview 07:22

Let's write a simple test together and understand how everything works.

Resources for this section Preview 00:21

Testing an API Preview 06:47

In this and the following lectures, you will be testing a real-world API and at the same time discover more and more feature of Postman.

We will take trello.com’s API (which is an online tool for managing lists and tasks) and create and test a few requests.

Testing an API - Writing more tests Preview 07:55

Troubleshooting Preview 00:10

Recap: Path parameters vs query parameters Preview 07:17

In this tutorial, I wanted to explain the difference between path params and query params and will exemplify this in Postman.

Create additional requests and tests

Starting from the previous lecture, you will call additional endpoints using the trello API in order to create a complete workflow.

Refactoring Tests Preview 04:03

Now let's refactor the tests that we have written so far, so that they are easier to read.

Variables in Postman Preview 02:06

Variables allow you can create more dynamic requests. 

Postman allows you to save repetitive information in a variable (which is very similar to what a variable is in any programming language). The main motivation for using variables would be to not repeat yourself.

Global variables Preview 10:09

This lectures explain what are global variables and what is their scope.

Environments Preview 06:39

This lecture discusses environment variables, which are defined inside environments, are quite similar to global variables but they have a more narrower scope, which means they are more specialised.

Session variables (new in Postman 6.2!) Preview 08:13

Postman 6.2 introduces a new feature called sessions, which allows you and your team to work more effectively through the addition of session-specific collection, environment, and global variables also called session variables.

In this video, I will show you how to configure and use session variables.

Bulk editing removed new in Postman 6.2!) Preview 03:06

Bulk editing has been removed in Postman 6.2 but in this video I will show you a way on how you can achieve the same result.

Pre-request scripts in Postman Preview 09:26

This lecture deals with pre-request scripts, which are similar to test scripts except as the name implies, pre-request scripts give you a chance to modify the request but before the actual HTTP request is made. 

Make the requests dynamic by taking advantages of variables

We already have a created a few requests which are linked to each other. The goal of this exercise is to practice variables and to reduce the amount of manual work needed in order to test the API.

Understanding different variable scopes / types Preview 11:37

In case you are confused about the different variable types in Postman (global, collection, environment, local, data variables), this lecture is a good way to get an overview.

How to setup different URLs using environments in Postman Preview 08:20

In this video i will show you how to setup different URLs for different servers / environments.

This lectures deals with debugging tests and scripts using the Postman Console.

Notice about the old Postman scripting API Preview 01:59

About this section Preview 01:17

This section gives you the opportunity to practice the skills you have learned so far. It uses real-world APIs to help you gain even more practical experience.

In this section lecture we will use the Github API to create a simple workflow.

We will create a new git repository, post an issue with some content, comment on that issue and so on. We will introduce 2FA authentication in the game and work with the Twilio API to receive a text message (SMS).

So if you have the time, this will be a fun project to work on.

Overview Preview 03:10

In this short lecture I wanted to give you an overview of what you will learn in this entire section. 

What we want to achieve is to run the entire collection (one request after another) and to get an overview of successful or failed tests. There are multiple ways to automate things and next I will give you an overview.

Postman collection runner Preview 07:38

The collection runner is included in Postman and facilitates the first step toward automation. It is a useful way to run the entire collection or just a subset of it (by selecting a specific folder) without any other external tools.

Postman monitors Preview 10:09

Postman Monitors allows you to run your collection at regular intervals. While this is a Pro feature, you can still try it out with a free account (currently you can make 1000 API calls per month).

Introduction to mock servers Preview 00:37

What is a mock server? A mock server is a fake API that simulates a server response, usually for testing purposes. A mock server allows you to mock any server or service that can be accessed by using HTTP.

Why use a mock server? Preview 05:39

Let's first understand what are the use-cases for using a mock server:

• API Design, prototyping and development (1)

• API testing (2)

Create your first mock server Preview 11:44

Learn how to create your first mock server with Postman.

Practical example: using mock servers for front-end development Preview 04:32

I have an Angular application which needs to data from the backend which is not ready yet. Using mock server I will demonstrate how to continue with the development.

Recording responses from an existing API Preview 04:41

Known limitations Preview 02:09

As with any software tool, there are always limitation or disadvantages. So let's what a look at what you should be aware of.

In this lecture I will show you how to debug an upload script and demonstrate it with Postman which can also make requests encoded as "multipart/form-data" so that you can send also a file.

Automatic the upload and testing process with Newman Preview 16:57

We continue the file upload project and move towards automatically running tests by using Newman. 

We will also look into uploading multiple files in a single test-run.

Basic access authentication Preview 05:55

Basic access authentication is a method in which the client provides a username and password while making a request to a protected resource.

Basic authentication is one of the simplest methods of implementing authentication.

I recently encountered it while dealing with microservices, so it is old and simple but still effective.
