Test Components

Test Components ensure data quality and pipeline reliability by validating your data at every stage. They provide comprehensive testing capabilities from simple column validations to complex custom business logic, helping you catch data issues early and maintain trust in your data pipelines.

Before you begin

• Ensure you have an Ascend Project and Workspace
• Have existing Components in your Flow to test against
• Review the Tests concept guide for comprehensive testing strategies
