Speeding up the code-test cycle for Java developers
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…

In plain words
This tool speeds up the testing workflow for Java developers by enabling direct function invocation without executing the entire call hierarchy. It features Direct Invoke, which allows developers to call any Java function independently—for example, testing an HTTP endpoint without triggering its full call stack. Built on the concept of IntelliJ's Evaluate Expression feature, it eliminates the need to set breakpoints and pause execution, making code exploration and sanity testing faster during development.

I built a tool to get instant test results2022 · github.com · ▲96I got sick of the old software development loop: Change code -> Run tests -> wait -> wait some more -> look at failures. I decided to build a tool that will enable you to: Change code -> look at failures. No wait time, no explicit test running. Under the hood: - Runs the whole test suite and collects code coverage per test. - For each auto file save, analyzes the changes on the tests. - Runs changed tests in the background. - Display results, the loop time from change to test results is approx 250ms. Instead of: code -> alt+tab -> arrow up -> rerun all the tests -> wait ... -> test results…

Talanoa▲343Hi 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…
