Spring Unit Test Generator

Generate unit tests for Spring with AI assistance. The tool analyzes your code, creates practical test cases, and can run them in a sandbox environment so you can quickly check whether the generated tests pass. It helps you improve coverage, catch regressions, and validate behavior without leaving your workflow.

Tests run automatically. This tool doesn't just generate unit tests — it also executes them in a secure sandbox environment and reports pass/fail results, so you get tests that are verified to actually work.

When to enable Web Access and Code Execution

These tools provide different kinds of context and verification. Enable them when they improve the task.

Web Access

Use for current docs

Enable Web Access when the task depends on current documentation, an external API, or a third-party package—especially a new, niche, or less familiar library.

For the best result

  • Paste the official documentation URL into your prompt.
  • Name the package and version you intend to use.
  • Ask the model to follow the linked API instead of relying on memory.
  • For multiple sources, say which source is authoritative.

Example: “Use version 4.x and follow the official documentation at https://docs.example.com/.”

Code Execution

Use for automatic checks

Enable Code Execution when you want the model to run the code, execute tests, reproduce an error, or compare the result with an expected output.

Particularly useful for

  • Algorithms with testable inputs and outputs.
  • Parsing, data transformation, and numerical tasks.
  • Debugging a reproducible error.
  • Checking that dependencies install and tests pass.

Credit note: Running and iterating on code may consume more credits than a single response alone. Leave execution off when you only need a small snippet you can inspect yourself.
