Why people use Test Assertion Density Calculator
Test Assertion Density Calculator for finding hollow JS tests
This Connector automates that audit. Your agent scans the files and tells you exactly where the density is too low.
What Vinkius changes
You stop trusting hollow coverage numbers.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

- Real-world use case 01
Cleaning up legacy suites
A developer finds a massive TypeScript file with high coverage but zero real tests and uses the Connector to find the gaps.
- Real-world use case 02
PR verification
An engineer asks their agent to check if a new PR introduces empty test blocks before merging code.
- Real-world use case 03
Refactoring safety
After a major refactor, you verify that your assertion density hasn't dropped across the entire suite.

Before you connect
Questions about Test Assertion Density Calculator.
The practical details behind the request, access and result.
How can I find empty tests in my JavaScript project with Test Assertion Density Calculator?
The capability scans your files and points to specific lines where assertions are missing. This helps you clean up hollow test blocks instantly.
Can Test Assertion Density Calculator help with TypeScript coverage?
Yes, it is specifically designed to analyze density in JavaScript and TypeScript suites to ensure real validation is happening.
Does Test Assertion Density Calculator work with existing coverage reports?
It provides a different metric than standard coverage. It looks at the ratio of assertions to blocks rather than just line execution.
How do I know if my test density is too low using Test Assertion Density Calculator?
You can use the health assessment feature to compare your current metrics against established industry standards.
Can I use Test Assertion Density Calculator to automate PR reviews?
Yes, you can ask your agent to scan new files for empty tests as part of your automated review process.
How does the capability identify empty tests?
The capability uses deterministic regex to find test blocks (it, test, dscribe) and checks if they contain any assertion keywords like expect, assert, or should.
What is a good assertion density?
A density of 2.0 or higher is considered robust, while anything below 0.5 indicates a high probability of ineffective test structures.
Can I use this with Vitest or Jest?
Yes, as long as your test files use standard keywords like it, test, expect, or assert, the capability will accurately calculate metrics.
