# What is SeaLights

SeaLights empowers development teams for **quality assurance and optimization**. By leveraging **AI** and **machine learning**, SeaLights **blocks untested code changes from reaching production** and **executes only the changed based tests**, for every test type and stage.

SeaLights provides valuable functionalities across the software development lifecycle, helping developers, QA engineers, testers, and stakeholders to **collaborate effectively** and deliver **high-quality software** faster and more efficiently.

## **Quality Visibility**

SeaLights acts as an X-ray for your software, providing **crystal-clear visibility** into its **overall health and quality**. You can track **coverage** not just for individual apps and entire projects, but also **specifically for new and modified code**. This granular insight allows you to identify **areas needing improvement** and understand the **trend of coverage** for recently changed portions.

This empowers you to **assess the effectiveness** of your **testing strategy** and **quality culture**.

## **Proof of Testing for Release**

SeaLights empowers you to **demonstrate to stakeholders** with confidence that **thorough testing** has been conducted before releasing your software. This **proof of testing** provides **documented evidence** of a **rigorous and reliable development process**. This is especially crucial for adhering to **compliance or regulatory requirements** that mandate documented testing procedures.

By showcasing the extent and effectiveness of your testing efforts, SeaLights helps you **build trust and ensure a smooth release process**.

## **Quality Improvement**

SeaLights fosters a **culture of continuous quality improvement** within organizations and teams. This collaborative approach, involving developers, QA engineers, and managers, prioritizes **immediate stability and release readiness** while fostering **long-term code quality and proactive risk reduction**.

By proactively identifying **testing gaps** and **creating new quality processes** with relevant **KPIs**, SeaLights empowers teams to **continuously improve** the overall quality and health of their software.

## **Test Optimization**

SeaLights ensures **precise coverage without compromising quality** by **focusing resources on what matters most**. By **analyzing code changes**, SeaLights prioritizes the most relevant tests, **reducing execution time** and **eliminating unnecessary tests**. This **improves efficiency**, freeing up resources for other testing activities or developer tasks.

Additionally, SeaLights enables **"shift-left testing"**, introducing advanced testing earlier in development for **faster issue detection and resolution**.
