Question: I'm looking for a tool that can create unit tests for my code without requiring a lot of manual effort.

If you need a tool to write unit tests for your code with a minimum of fuss, RoostGPT is a great option. This AI-powered testing tool uses large language models to write unit and API tests at scale, ensuring good test coverage. It automates testing, accelerates projects and plugs into common tools to help you write better code and get better coverage.

Another option is CodeComplete, an AI-powered coding assistant that's available as a self-hosted tool designed for enterprise customers. It's got tools for automated unit test generation, automated documentation, refactoring and migration, all designed to boost developer productivity. With its analytics and permissively-licensed repositories, CodeComplete also helps protect your code and data.

If you're a VS Code user, CodeAI is a useful extension that uses artificial intelligence to help with code generation, unit tests and documentation in multiple programming languages. It's got a free plan with limited AI model calls and more expensive plans for solo developers and pros, but it's a good option for anyone who wants to boost coding productivity.

Last, you could try CodiumAI, which plugs into popular IDEs like Visual Studio Code to write useful tests and review code. It's got tools for useful test generation, code reviews and behavior coverage, all designed to boost productivity and ensure your code is in good shape. It's free for solo developers, but there are paid options for companies.
