Go LeetCode Framework

A Go-based framework to make solving LeetCode problems easier.

Adapted from a video by Tom on the Internet

🚀 Features

• ⚙️ Auto-generated test files using gotests
• 🔁 Auto-reloading test runner using gow
• 🧪 Write, test, and iterate quickly on Go solutions to coding problems
• 🗂 Clean structure, minimal setup

🚧 Getting Started

First, install the required tools:

go install github.com/cweill/gotests/...@latest
go install github.com/mitranim/gow@latest

Then:

# 1. Clone the repo
git clone https://github.com/alex-r89/go-leetcode-framework.git
cd go-leetcode-framework

# 2. Create a new folder for the problem
mkdir your_challenge_name

# 3. Generate a test file (also creates the solution file if missing)
gotests -all -w -parallel your_challenge_name

# 4. Open the test file and:
#    - Use your editor to expand the generated test struct (VSCode: cmd + .)
#    - Fill in example inputs from LeetCode into `args`
#    - Fill in expected output into `want`
#    - Repeat for as many test cases as needed

# 5. Run the tests using gow
gow test 1-two-sum/1-two-sum.go 1-two-sum/1-two-sum_test.go

Now you can iteratively fill in your function logic and instantly see if the test cases pass.

📁 Structure

Each problem lives in its own folder, containing the solution file and its corresponding _test.go file.

.
├── 1-two-sum/
│   ├── 1-two-sum.go
│   └── 1-two-sum_test.go
├── 2-longest-substring/
│   ├── 2-longest-substring.go
│   └── 2-longest-substring_test.go
...

---

🧪 Example

See 1-two-sum/1-two-sum.go and 1-two-sum/1-two-sum_test.go for a basic example of how a solution and its tests are structured.
