Esther.ai - AI Powered QA & Cybersecurity Testing - Full List of 42 Test TypesSoftware ConsultantsUpdated on Sep 16, 2026 View more like this | Visit POMPANO BEACH, FL | Contact Esther.ai Corporation |
Esther.ai accelerates and reduces the cost of introducing new market features by leveraging generative Artificial Intelligence (AI) to create, execute and report on Quality Assurance (QA) testing.
Esther minimizes software testing costs, time and effort.
She detects issues, defects and vulnerabilities earlier in the Software Development Life Cycle (SDLC) and increases both functional and non-functional testing coverage, all without the need for scarce human resources.
Not only will Esther find broken code, she will fix it! ("Find and Fix")
Esther uses AI to power QA (Quality Assurance) and cybersecurity testing at large scale for browser-based websites and applications. Up to now, this has always necessitated human intervention.
Main Differentiators (vs. other forms of QA testing)
1- 100% automated - human resources are scarce.
2- Push a button and go - no need to prime the system with scripts or other human intervention.
3- Fast - lightening speed compared to legacy processes
4- Find - identify suspected issues with clickable specificity
5- Fix - once Esther finds the problem, she can fix it on the spot. Users can choose to proceed or not.
6- Accessibility - Esther can mimic a human user to ~95%. "Test this website as if you were visually impaired."
7- 42 automated test types - including security, vulnerability & penetration testing (with certain tests, such as security, she can't replace humans at 100% - just ~80% - the last ~20% needs to be performed by a human.)
8- Cost - pennies on the dollar!

These are not real actors - can you believe it? : )
Esther is a QA & testing software powered entirely by Artificial Intelligence.
Esther performs 42 test types and she is 100% AI-driven - no human intervention is needed for her core operation. After she identifies defects (as a tester) she then repairs them (as a developer.)
"Find and Fix" - The Holy Grail of QA and cybersecurity.
Esther is unique in this regard, and to our knowledge, there is none other like her.
Our Founder & CEO, Rick A. Hensbergen, has extensive experience in testing and security, primarily in the banking sector, including with Metro Bank, Deutsche Bank, Lloyds Banking Group, Bank of America, Barclays, Merrill Lynch, J.P. Morgan and Royal Bank of Canada.
Three of our forty-two tests address cybersecurity:
- Security Testing
- Penetration Testing
- Vulnerability Testing
We are bootstrapped and close to landing our first customers!

38- Compliance Testing
Technical Testing
1- Unit Testing - Tests individual pieces (units) of code to ensure they work as expected. The goal is to catch bugs early and ensure each part functions correctly before integration.
2- API Testing - Checks if different software components communicate properly via APIs, ensuring data is sent and received accurately to prevent broken connections.
3- ETL Testing - Verifies the Extract, Transform, and Load (ETL) process to ensure data moves correctly between systems, preventing incorrect, missing, or duplicate data in reports.
4- Data Warehouse Testing - Tests large-scale data storage for accuracy and performance to ensure business reports and analytics are based on reliable data.
5- Backend Testing - Focuses on the server-side components, databases, and APIs to prevent crashes, slowdowns, and incorrect data handling.
6- Component Testing - Tests individual software components in isolation to identify and fix issues early before integrating them into the system.
7- Database Testing - Ensures data integrity, performance, and consistency in databases by verifying that queries and transactions work correctly.
8- Smoke Testing - A quick test to check if the main features of an application function correctly, ensuring it's stable enough for further testing.
9- Infrastructure Testing - Verifies that servers, networks, and cloud services work properly to prevent downtime and performance issues.
10- Configuration Testing - Ensures software runs correctly on different hardware, operating systems, and settings, preventing deployment issues.
11- Firmware Testing - Validates software embedded in hardware devices to ensure they operate correctly under expected conditions.
12- Version Compatibility Testing - Checks if a new software version works well with older versions to prevent compatibility issues when updating.
13- Interface Testing - Tests how different systems or components interact to prevent failures due to broken connections.
14- Code Review & Static Analysis - Examines code without running it to detect bugs, security risks, and inefficiencies before deployment.
