Web applications typically consist of an HTML-based front-end and back-end services, which provide particular functionality like credit-card processing or user-management. The front-end heavily depends on those back-end services, and if the back-end is not accessible or under development, it is hard or even impossible to continue testing the frond-end. With the new embedded SV capabilities of Silk4J, the back-end services are no longer a bottleneck for development testers. Instead, you can simply simulate key services and avoid waiting for the back-end to be ready. Using SV with Silk4J is as simple as recording a test case.
