Generating meaningful tests for busy devs

With CodiumAI, you get non-trivial tests (and trivial, too!) suggested right inside your IDE, so you can code smart, create more value, and stay confident when you push.
Code, as you meant it.

Write code that works
the way you meant it to

By analyzing your code, docstring, and comments, and by interacting with you,
TestGPT suggests tests as you code. All you have to do is accept and commit them.

    coefficients: NDArray[float64], vector: NDArray[float64]) -> NDArray[float64]:
    
    if (check_valid_input(coefficients, vector) == False):
        return np.array((), dtype=float)

    rows, columns = np.shape(coefficients)

    # augmented matrix
    augmented_mat = create_augmented_matrix(coefficients, vector)

    # scale the matrix leaving it triangular
    augmented_mat = scale_matrix(augmented_mat, rows)

    x = retroactive_resolution_full_augmented_mat(augmented_mat, columns)
    return x

Code smart

Get full visibility of how your code behaves and how the changes you make affect the rest of your code.

Create value

Spend fewer hours writing questionable test cases and more time developing useful features for your users.

Stay confident

Unlike code coverage quotas, meaningful tests actually check your code’s functionality. So you get the confidence needed to commit.

Generates meaningful tests that help
you understand how your code behaves

Generate meaningful tests, find edge cases and suspicious behaviors, and be empowered to write reliable code.

CodiumAI works like a charm! I would highly suggest it to every developer. It is easy to use, and it decreases the development time significantly (especially for the ones who do not like writing tests). Kudos to the developers!

When I started using CodiumAI, all the guesswork disappeared immediately, and my confidence soared. I identified use cases that could be buggy, well before my contributions reached the tests. It boosted the quality of my work and reduced the time I spent on writing test cases.

Using CodiumAI, I was able to spare the time that I would have to spend thinking about use cases that should be tested, and still got really reliable unit tests, written in the way that I needed, and also with an explanation about what each one of them was testing.

Really simple to use, and does a lot of the “heavy lifting” required when testing your code. Best feature for me is the explanations of the tests generated, as it helps you avoid allowing false positives.

Writing unit tests is extremely important and any developer needs to know. This tool helps me a lot to increase the coverage of my tests with my Python codes, I’m loving it!

CodiumAI is a game changer in test writing. It’s easy to use, flexible, and helps you catch errors early in a development process. It’s a must have tool for any developer who cares about quality of their code.

I was blown away by how CodiumAI was easy to use. Just by performing the analysis and creating the tests, it helped me remember what the code is supposed to do, and provided safeguards for future refactoring or re-writing efforts. I highly recommend CodiumAI to anyone looking to streamline their code testing process, especially when dealing with legacy or undocumented code.

CodiumAI isn't perfect

You should always double-check the tests CodiumAI generates

AI and ML have come a long way, but they're far from perfect. So while CodiumAI helps you break fewer things and be more productive, it needs your help to do so. That's why we designed it to be interactive – so you can edit the tests it generates and perfect them.

Found a bug?

I have a few
questions…

  • Why don’t I just ask ChatGPT/Copilot to write my tests? How is CodiumAI different?

    Unlike general-purpose code completion or generation tools, CodiumAI is focuses on code integrity: generating tests that help you understand how your code behaves, finding edge cases and suspicious behaviors, and making your code more robust. CodiumAI is not another fancy ‘Language-model-API in your IDE’, because - a. We’re pro at testing-domain prompting b. We parallelize and chain multiple prompts to create a unique variety of meaningful tests c. We efficiently gather broad code context for the prompts d. We let you interact on each test separately.

  • When will I be able to start using CodiumAI? Is it free?

    You already can! Just download our free VSCode extension and/or JetBrains plugin and get meaningful tests. CodiumAI is free for individual developers, and we even plan to publish an open-source. In the future, we'll launch a paid plan for enterprises.

  • What languages are supported?

    We support Python, JavaScript, and TypeScript in VScode & JetBrains IDEs. We will support Java soon.

  • How does CodiumAI make sure my code stays secure?

    We take security, privacy, and compliance very seriously. CodiumAI only analyzes the code necessary to give it enough context to generate meaningful tests, and the data is SSL encrypted. Also, we are SOC2 certified.

  • Does CodiumAI write perfect tests?

    AI and ML have come a long way, but nothing's perfect. While CodiumAI can boost your productivity and improve code integrity, please always double-check the tests it generates. We are here to give you superpowers, but you still need to think and use them wisely.

  • I want to join you guys!

    We’d love to have that conversation. Feel free to email us at [email protected], please attach your resume.
