What you will learn

Understand the differences between Monolithic and Microservices Architecture

Realize the Importance and necessity of Contract Testing in the Microservices Architecture

Learn to build effective Contract Tests using Pact Testing tool to test the Inter communication between two Systems

Understand writing Consumer Driven & Provider Tests to generate the Integration check of two services

Deeper Understanding of Pact Contract Testing tool and its related Orchestrator tools like Pact flow to centrally manage Contract files

Description

" Contract Testing " is one of the most buzzing word in the Software Industry especially in the projects which relies heavily on Microservices Architecture.
Contract testing is the Modern way of testing communication/Contract between two any Systems (Such as Microservice, Angular NodeJS, Java Apps).    In Agile world, Contract Testing  is heavily used in the bottom of the Test Pyramid  to identify the bugs in early development cycle. 
***For More details, Please watch Preview lectures of this course to get detail understanding of how and Why Contract Testing****
In this course, We shall be using Pact Contract testing tool (Java Library) to test the inter communication contract between Microservices

What this Course offers?

This course  helps you to understand all the concepts revolving around Contract testing first to make you realize the importance of having these tests in the Projects
And then introduces the Contract testing tool called Pact and gets deep dive into writing Consumer & Provider driven Contract tests to test Microservices Inter communication.
I will also show you different helper orchestrator tools available such as Pactflow to centrally manage Contract files across the Projects.

On course completion, You will have thorough understanding of how Microservices communication works internally and how can we test this communication using Pact Contract Testing tool.

Course is good to start with pact broker but there are several places where I felt course could have had better explainations. Overall good course.

Course seems pretty outdated, especially the code source. Would have loved to have this in an IntelliJ environment with more current JDK. Maybe maintain the sources on a github repo might also help. What would also be great it to use a step-by-step to build an API application using PACT instead of providing a huge code project of unknown code.

Yep. After the setup of consumer/provider microservices that was a little bit tricky it became more smoothly.

Hello, I am unable to proceed the course due to NoPactFoundException error. A same question is there in qna section, no answer is provided. Please give some solution

This is SO TERRIBLE. Avoid this course even if it offers you 1 cent as a sale price. Please, value your time. You can find much more effective and comprehensive guidelines on the official Pact website.

Absolute disappointment, the code examples provided simply do not work, I fixed some of them myself. The tests written also do not work. I had to stop watching this tutorial, and look somewhere else on the internet for the same topic. This course seems to be outdated. I've taken other courses for the same author and they were all good. Not this one though, don't waste your money on it.

Already setting up the example servers is not working and i refrained from asking as some of the questions were already 10 months old so i didnt expect to get an answer.

Los comentarios son muy deficientes y muchas veces no se comprendía la idea a la que quería llegar, además de tener algunos videos x2 automáticamente, lo cual generaba que tuviera que estar más atento a los subtítulos que al código.

The course explained very well, I wish would have covered more concepts with multiple examples of http codes and errors

I think you need to write in Headers about, this example for JVM. I expect more theoretical information but in this course more hands-on writing tests in the vacuum.

Got PactsNotFoundException and tried so many ways. even the code which he provided also I have run in my STS but showing same error no response till now

In general it's cool, but I miss some points on e.g. how to make post, put, patch & delete requests with path, maybe also how to test on contract some websockets

Very nice i detail explanations. Contract testing is very new to me but after completing course feeling confident. Thanks

The course is outdated and has many dependencies errors and when it is managed to raise it to the new dependencies, the project does not work. Do not buy it because it does not work properly. the course serves to know how it was done a year ago, not for today because there are comments from the author in the code that are even incomplete. I wrote to him to see if he answers me and there is no answer to date

bit long winded - i do appreciate though that the lecture is trying to cover all skill levels. There is also in the back of my mind a question about whether describing the monolith as a single server is more accurate than just describing it as a single code base providing a single repo point for delivering multiple services. I dont think most corporate instances would have a single server
