The End of Manual Unit Testing

Every developer knows unit tests are crucial for code quality. Yet writing and maintaining them consumes up to 35% of development time. Your team faces a constant choice: delay shipping to write tests, or ship faster with less coverage.

CodeBeaver eliminates this tradeoff. Our AI platform analyzes your code and automatically writes comprehensive unit tests with every pull request. No more choosing between speed and quality.

How It Works

The AI agent for software testing.

When you open a pull request, CodeBeaver springs into action:

1

Intelligent Analysis

Our AI reads your code and comments to understand what your functions are supposed to do, just like an experienced developer would.

2

Test Generation

CodeBeaver writes targeted unit tests that cover both common cases and edge scenarios human developers might miss.

3

Automatic Validation

Unlike basic AI solutions that just generate test code, CodeBeaver runs every test it writes. If a test fails, our AI analyzes the failure and iterates until the test passes.

4

Seamless Integration

All tests arrive as a separate pull request you can review and merge. No configuration needed - it works where your team already works.

Why Engineering Teams Choose CodeBeaver for Unit Test AI

01

Ship Faster With Confidence

Your code ships when it's ready, not when tests are written. CodeBeaver handles test writing and maintenance automatically, removing a major bottleneck from your development process.
02

Save 30-45 Minutes Per Developer Daily

That's what our users report saving on average. Instead of writing and updating unit tests, your developers can focus on building features that matter to your users.
03

Zero-Maintenance Testing

When your code changes break existing tests, CodeBeaver automatically updates them. Changes arrive as pull requests, so you maintain full control over your test suite.
04

Native Git Integration

Install in 30 seconds on GitHub, GitLab, or Bitbucket. CodeBeaver works in your existing workflow - no new tools to learn or processes to change.

The CodeBeaver Difference
