# Test Optimization Savings Breakdown

Test Optimization Savings Breakdown provides a comprehensive overview of test execution performance and savings for a specific app and test stage. 

## Timeline

The page includes a timeline with:

* Build events, with a summary of the test savings (or potential savings) out of the total tests reported 
* System events (e.g. scheduled full test run) 
* User action events (e.g. TIA turned off/on, full run policy change). 

## Test Execution Data & Insights 

Users can view test execution data and detailed insights into each individual build, including:

* **Test Execution Summary and List:** The total number of tests passed / failed, executed / skipped, along with the skipping reason. And a detailed list of all reported tests.
* **Impacted Tests:** Detailed list of code changes and their corresponding tests for each build.
* **AUT (Application Under Test):** Available for apps that combine a few components (apps) for advanced testing (cross app testing), displays the list of apps with the specific branch and build. There is an access to the build monitor (for Admin / DevOps) to explore more technical details. 

## Charts & Graphs

Users can open an additional view with charts describing the savings (in compute time or in number of tests) per build, with a clear visualization of the trends over time and the ability to analyze the potential savings before turning on the TIA.

By combining these elements, the Savings Breakdown empowers users to understand the factors driving test efficiency, pinpoint areas for improvement, and make data-driven decisions to optimize testing processes.

SeaLights Test Optimization simplifies your testing process by analyzing code changes and recommending which tests are directly impacted. Here's how it works:

1. **Automated Test Reporting:** SeaLights automatically collects data from your tests through integrations with various testing frameworks or using its APIs.
2. **Test Optimization Engine (TIA):** Starting from the second build, TIA analyzes code changes and historical data to identify tests impacted by modifications.
3. **Recommendations and Execution:** TIA recommends skipping or prioritizing tests based on their relevance and according to a pre set [Test Selection Policy](https://docs.sealights.io/knowledgebase/test-optimization/test-optimization-strategy/test-selection-policies). These recommendations are automatically applied and executed through integrations or by using the APIs.
