Introduction to Test and Behavior Driven Development

Successful developers need to not only build the right software but build it right. To know your software works correctly, you need to test each unit of code. One of the best methods for this unit-level testing is test driven development. This course provides a detailed overview of test driven development (TDD). First, you’ll learn what automated testing is and why it is essential for building robust applications resilient to failure. You’ll explore the basics of testing, including test cases, testing levels, and the traditional release cycle. You’ll learn about TDD and its complement, behavior driven development (BDD): TDD tests individual units of code while BDD tests how these units work together. Then you’ll examine TDD in detail. You’ll explore TDD’s benefits, concepts, and popular tools, and you’ll hone your new testing skills through hands-on labs. You’ll create TDD test cases by writing test assertions and building test fixtures, and you’ll run these test cases by using the Nose testing package. You’ll then practice more advanced TDD methods such as increasing code coverage, generating and using fake data, and testing mock objects.

The course offered by Coursera is Amazing. The Couch was good & the way he delivers & the way he teaches was good. But the review system is very slow. Which will let peers do the review.

This course was well planned and easy to follow. The demo lessons were very helpful with understanding how tests should be conducted. Great class, and great instructor.

Very good. Try to complete the final project without copying the solution for a better understanding of what is a test-first approach.

Very good course, although I wish they focused more on TDD Workflow examples rather than Python specifically.

I didn't know how important it is to test my code until after taking this course. The course is well structured, and well explained with hands-on practice which bolster understanding. I really enjoyed every minute of learning about tests and the different techniques for writing a good test.

This couse is very helpful to understanding "crafting" work of programming. It's not about the python language, but about how the developer can manage his/her attention and how to progressively change requirements into codes with confidence.

Hello, I'm not able to access modules 11, 12, and 13. I paid the complete course fee and after completing module 10, I found out that modules 11 and 12 are locked...

The course is about CI/CD. it's ridiculos

I would say that I absolutely loved it! The course was packed full of useful concepts, all of which were explained in a clear and easy-to-follow manner. But what really set this course apart was the emphasis on practice. Through a series of engaging exercises, I was able to put my newly acquired knowledge into action, and really start to solidify my understanding of TDD. Overall, I would highly recommend this course to anyone interested in learning more about TDD. It's a fantastic way to get started, and I know that I'll be referring back to the concepts and techniques that I learned here for years to come.

Good balance of theory and practical labs, concepts were well explained with a good level of detail. The course has improved how I code and made my development more test-driven. I would recommend this course if you want to write more robust and higher quality code. The course seemed geared towards e-commerce/ commercial apps. I think an improvement would be to show how to write tests in additional domains i.e working with data other than account data. For example I would have liked to know how to mock/patch more complex classes.

Really awesome. John Rofrano is a really great teacher and has a lot of practical experience. In this course, you will learn everything you need about Software Testing, both theory and practical materials, and you will be given all the questions that you may face. This course's lab is based on Python, but don't worry, he will teach you everything you need to understand and practice. I didn't know Python, but it was really easy, and I enjoyed this course and completed all the labs by myself

The course is well structured and easy to follow. The instructor is great and explains the concepts and details in an easy understandable way. The only downside that I see is that the "nose" package used in course is not actively maintained any more (and, as far as I know, does not work with recent Python versions). Nevertheless, this hardly impacts the overall experience. If you want to get a decent understanding on how to apply TTD, give this course a shot.
