IntelliJ plugin to auto generate boilerplate code for Java unit tests
Generate a test class with code to construct the source class, initialize the dependencies and create test methods. Each test method contains code to initialize the arguments, invoke the source-method and compare the returned value to an expected value.

In plain words
IntelliJ plugin that generates boilerplate code for Java unit tests. It automatically creates test classes with constructors for the source class, initializes dependencies, and generates test methods that set up arguments, invoke methods, and assert expected values. The plugin uses a customizable Velocity template system to adapt test generation for different frameworks and dependencies.

JavaFactory – IntelliJ plugin to generate Java code2025 · github.com · ▲44Hi HN, I built a code generator plugin for IntelliJ that uses LLMs to create repetitive Java code like implementations, tests, and fixtures — based on custom natural-language patterns and annotation-based references. Most tools like Copilot or Cursor aim to be general, but fail to produce code that actually fits a project structure or passes tests. So I made something more explicit: define patterns + reference scope, and generate code consistently. In this demo, 400 lines of Java were generated in 20 seconds — and all tests passed: https://www.youtube.com/watch?v=ReBCXKOpW3M…
- SUSpeeding up the code-test cycle for Java developers2023 · ▲69
Hello HN, I am Parth. In my experience, the current form of testing automation takes too long. To solve this, I am creating a developer tool to speed up the code-test cycle for Java developers. It has two main parts: Direct Invoke - lets you call any Java function directly, without the need to execute the whole call hierarchy. (e.g. an HTTP endpoint) In my normal coding workflow, I use the “Evaluate Expression” feature inside IntelliJ IDE. I usually put a breakpoint somewhere in the code and after hitting the breakpoint by calling an HTTP api, let the execution remain paused while I explore…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
