The company suggested that I write a test code, but I don't have any previously written code, and I have to study and write it on my own. I was at a loss when I searched Google, and when I heard Captain Pangyo's lecture while studying Tasna View, I immediately took the new lecture because he released it. He explains the environment settings and error parts well, so I can work without spending too much time following along compared to other lectures.

I took this course because I felt like I was lacking in things I had been doing unit tests all the time. I am not a professional developer, but it was very helpful for me while working on toy projects. Thank you!

I've only been doing unit tests with Jest every day, but this time I'm learning about Cypress and E2E tests for the first time. I found it really interesting while studying, so I had fun listening to the lecture! Thank you for the great lecture again :)

Just as important as the ability to implement features quickly is ensuring the stability and completeness of the implemented features. You need to carefully check every time whether the code you've written affects existing functionality.
Repeatedly checking feature functionality is tedious and cumbersome. Especially since it delays our time to leave work, we should never test only manually by hand.
Test code and test automation help us spend our precious time on more valuable things. Let's deepen our understanding of testing through this course to work smarter and become a recognized frontend developer!
📌 6 years of writing test code. A course that fully conveys the deep expertise accumulated through countless back-and-forth exchanges with QA (Quality Assurance) professionals
📌 A practice-focused course (90%) that teaches from the basics of testing theory through 1 mini project and 1 real-world project
📌 Not sure why we test or how to write test code? The course explains it clearly.
📌 How do professionals think about test code in practice? We'll show you everything about how to write it effectively.
📌 We introduce methods for designing test scenarios from a user's perspective.
I'm interested in testing.
I hear that test code is important, but I don't know where to start.
I want to become good at frontend development
I can implement features fairly well,
but what should I do
to become a next-level developer?
It's annoying to check everything every time I deploy
It's so tedious to manually check if features are working every time I deploy a service. Is there an easier way?
Your hands, not just your head, will understand why test code is necessary and what needs to be tested.
You'll learn how to write test code concisely and effectively.
You can break the habit of manually checking things repeatedly and automate feature verification.
You'll be able to take the code quality and completeness of your web application to the next level.
You'll find it easier to work with the Cypress testing tool.
Basic concepts of testing and overall testing theory
We explain the overall testing theory and fundamental concepts that web developers must know through course materials.
From basic usage of testing tools to error interpretation
We'll cover everything from basic usage of testing tools to useful features for each UI. In particular, through live coding, you can experience creating errors together, analyzing them, and fixing them.
Test scenario design methods and progressive refactoring
I'll share my years of experience in writing test scenarios. You'll learn to systematically structure the code you've learned and improve the quality of your test code through refactoring.
Start with a mini project and finish with a real-world project.
Learn both basic and advanced concepts by writing test code for a simple counter app and a feature-rich shopping mall site. Packed with practical tips from real-world experience
