Subject: General Availability Announcement for HB.js Extension for VSCode 1.3
On behalf of Broadcom, we appreciate your business and the opportunity to provide you with high-quality, innovative software and services. As part of our ongoing commitment to customer success, we regularly release updated versions of our products. Today, we are pleased to announce that HB.js Extension for VSCode 1.3 is now available.
This new release provides enhanced 3270 end-to end testing support – a major enhancement to the HostBridge platform designed to accelerate modernization and testing workflows. Testing 3270 applications has historically been a manual, time-consuming process. With the latest release, HB.js provides the ability to automatically generate 3270 test scripts as high-performance APIs. It allows developers to generate HB.js tests using field name (not screen coordinates), making tests more resilient to screen layout changes. The Application Explorer speeds creation with screen recording and code generation, improving coverage while reducing manual effort.
We encourage you to visit the HB.js Support product information page and Tech Docs.
You can download your copy of HB.js Extension for VSCode 1.3 online at Support where you can also utilize the case management system. To install the product, follow the installation procedures at Tech Docs. If you have any questions or require assistance, contact Support.
To connect, learn, and share with other customers, join and participate in the HostBridge community.
