Advanced Mainframe Test Automation with Precision & Efficiency
Avo Assure’s no-code test automation optimizes mainframe testing by enabling full-stack validation across IBM 3270, 5250, and green screen applications, ensuring seamless workflows and data integrity.
Complex Mainframe Testing Challenges
Legacy System Complexity
Testing IBM 3270, AS/400 (iSeries), and mainframe batch processes require extensive expertise.
High Manual Effort & Test Execution Time
Script-based and manual testing lead to inefficiencies.
Data Validation Across Interfaces
Ensuring consistency between mainframe databases (VSAM, DB2) and external systems is challenging.
Complex Batch Processing & Job Scheduling
Validating batch jobs and workflows is manual and error-prone.
