“The developer firewall” in a real empowered shift left scenario.

CI Fuzz supports developers when writing code and locally executing AI tests just from the IDE exactly like for Unit Tests.
The developer firewall

Full transparency and control of what is tested and all flexibility to optimize tests based on needs. No black box voodoo with no control.

Results are put out on a local machine while writing code. For regression testing and for the AI powered issue discovery mode.

No new tooling, no new processes. Just like every Unit Test.

Covers negative testing for hidden issues and edge cases. Find more time to focus on the business logic.

Protects any refactoring and ensures behavior does not change.

Full support for Unit, API and other Integration tests.


Frequently asked question CI Fuzz

Does CI Fuzz find all bugs in software?

No other testing method can generate most relevant test cases faster. While executing we find most issues like exception’s error responses or security vulnerabilities. Testing the business logic for the expected results will still be done with a few standard tests.

CI Fuzz does find all the unexpected behavior for edge case input. Does it find all security issues?

We focus on OWASP Top 10 issues and protect against injections of various types, remote code execution and many more. For system and infrastructure security (server versions, web server configuration, fire walls) use methods like pen testing.

Can CI Fuzz help with functional testing as well?

Wherever you can ensure some code to be functional by e.g. processing an input and in another call undoing this with the output, CI Fuzz can safely test this is the case for all potential input. When you need to ensure a new code segment produces the same results as old code did, CI Fuzz is your tool. CI Fuzz will not be able to check your business logic: Certain input needs to result in certain output. For this you will use your standard tests.

What in a nutshell makes CI Fuzz so special?

It is the different approach. Typical tests check one input and ensure specific output. May it be the expected business processing. May it be input considered to be invalid and handled properly. CI Fuzz automatically finds input that causes different code to be executed. CI Fuzz hooks in all calls and evaluation of conditions like if-then-else and finds ways to trigger different results. And on top and while doing this, all code is security checked.

Can CI Fuzz reach 100% code coverage?

Yes, absolutely. For some code additional input from the person knowing the code might be needed to get the last mile from 80 to 100. CI Sense allows to analyze and easily add required information.

Is there an easy rule of thumb when exactly CI Fuzz replaces a lot of tests and allows to focus on business logic?

In all situations where you can envision a test "Under no circumstances X must ever happen", CI Fuzz is your help to fully cover. You just add a few standard tests to ensure business logic. Security is tested on the fly. All done.

“One of the biggest advantages of instrumented fuzz testing is that you can execute your code in a Software-in-the-Loop simulator. My favourite part of instrumented fuzzing is that finding the root cause is so easy, and for a manager, it means I can save budget.”
