Automatic test maintenance

CodeBeaver automatically adapts your tests to your code changes. When you change your code, CodeBeaver updates the tests - unless there's a bug.

Integrations & Support

Same workflow, easier testing

CodeBeaver integrates with your existing workflow and tools, so you can focus on shipping features.

GitHub, GitLab, Bitbucket

CodeBeaver integrates with GitHub, GitLab, and Bitbucket, so you can use it in your existing workflow. We also support GitHub self-hosted.

Auto-configuration

CodeBeaver can automatically configure itself for common frameworks, such as pytest, unittest, jest, and so on.

Triggers

CodeBeaver can kick in automatically every time you open a Pull Request. But you can also activate it for a specific set of files, for your whole codebase, for a particular commit.

Pre-Commit Hooks

Got pre-commit hooks in your repository? Great. CodeBeaver respects and executes any pre-commit hooks you have configured, ensuring a consistent workflow. No need to set anything up.

Can't I just generate tests with Copilot or Cursor?

Writing the initial test is only 10% of the work. The real time sink is:

Running the tests and fixing syntax errors
Debugging failing assertions
Sifting through test results
Maintaining tests as your code evolves

CodeBeaver handles all of this for you - delivering ready-to-merge, working tests that actually run.

How it works

Process Overview

You Open a Pull Request

Your development team opens a Pull Request or commits new code to your repository (Read the documentation about triggers)

CodeBeaver Runs the Tests

CodeBeaver automatically runs your existing test suite against the changes. In most cases, there's no setup required – CodeBeaver analyzes your codebase and intelligently determines how to run your tests.

Test Failure Analysis

If any test fails, CodeBeaver analyzes the failure and determines if it's due to a bug or to an old test.

Bug Analysis

After finding a bug in the code being tested, CodeBeaver writes a detailed report to help you fix the bug.

Tests are Updated or Added

When necessary, CodeBeaver generates new tests or updates existing ones to ensure comprehensive test coverage.

Validation

CodeBeaver validates all newly generated tests by running them against your codebase, discarding any that fail to perform as expected.

Pre-commit Checks

Just like a human developer, CodeBeaver executes any configured pre-commit hooks and additional checks in your workflow.

Pull Request Creation

CodeBeaver creates a new Pull Request in GitHub, GitLab or Bitbucket, using your original code changes as the base. The PR appears in your workflow just as if it came from another member of your development team.

Don't worry about unit tests again.

CodeBeaver writes and runs your tests - spotting bugs.
