# Test Collections
Collections are reusable groupings of test cases for efficient test planning. They can be built manually by selecting specific test cases, or dynamically using filter rules (e.g., "all test cases in the Auth folder with type=Regression"). Collections streamline cycle creation by allowing bulk addition of relevant test cases.
### Overview
The Overview tab stands from different cards:
* Main card contains the main data
* Test Case Sources card shows how testcases added to this collection
* Details shows main attributes
* Usage Insights highlights how frequently the collection being used
### Test Cases
Test Cases tab shows which test cases has been added manually to the collection.
### Rules
Rules can be created to ensure quick test cycle creation, based on always evolving test cases.
**Folder rules**: Select a folder with its possible children
**Field Conditions**: Select the field, then select the expected values
**Groups**: combine multiple conditions with AND/OR to build complex rules
{% hint style="info" %}
User can always decide to build rules with Visual, Basic or BQL filters.
{% endhint %}
### Planning
Default assignee can be set on Planning tab, so that adding a collection to a cycle would automatically fill testers to executions. This is just a default value, it can be changed in the cycle any time.
