Your Test Suite Is Lying To You.
It says "100% Coverage," but your codebase is full of blind spots and hidden behaviors. TestMutant is the automated lie detector that forces you to verify what your code is actually doing.
Eliminate blind spots. Start verifying intent.
The Codebase Knows Things You Don't.
You think you know how your application behaves. You don't.
Over time, your codebase has accumulated "Hidden Behaviors", logic that runs in production but exists in no specification.
The "Ghost Rule":
A developer added a special discount case three years ago. It’s not in Jira. It’s not in the docs. It’s not tested. It is running right now, affecting revenue, and nobody knows it exists.
Documentation is Fiction:
The moment a requirement is written in a ticket, it’s out of date. The only source of truth is the code, but standard tests don't tell you which code is actually protecting your business rules.
We Force the Conversation.
TestMutant does more than catch bugs. It uncovers intent. We challenge your logic to prove it matters.
Exposing the Unknown:
When we break a line of code and your tests stay silent, we expose a piece of logic that is currently operating without a license.
Intelligent Filtering (Zero Noise):
We respect your time. We don't verify every single line of boilerplate. We intelligently filter out the noise to only flag the critical decision points that actually change your application's output.
Living Specifications:
Stop relying on stale tickets. We map every verified behavior to the test that enforces it. The result is a real-time specification that documents exactly which business rules are locked down and guaranteed to work.
The Lie vs. The Truth
Scenario: A hidden perk if (cart > 100...
The Lie (Standard CI)
Status:
Build Passed
The Test:
Checks cart total. It passes.
The Blind Spot:
Code is executing business logic (isVIP) that no test is aware of.
The Risk: Unintended features running wild.
The Truth (TestMutant)
Status:
Shadow Logic Detected
The Test:
We ran the same test. It still passed.
The Insight:
"I removed the VIP perk and nothing failed. Did Product approve this rule?"
The Value: You validate the rule or delete the dead code.
