What it is
Apex Hammer is an internal Salesforce regression testing process performed before major service upgrades. It automatically executes all customer Apex unit tests twice—once in the current version and once in the release candidate version—to identify and resolve potential functional regressions before new releases are deployed.
Features
- Automated execution of all customer Apex unit tests twice per major release cycle
- Comparison of test results between the current platform version and the upcoming release candidate version
- Proactive identification and patching of platform regressions by Salesforce engineering before release deployment
Best for
- Load Testing scenarios across typical web and service stacks
- Organizations budgeting for commercial licenses or subscriptions
- Groups comfortable scripting in Apex
Not the best fit when
- Strictly air-gapped environments with no approved cloud path
- Projects that require a fully free open-source stack only
Architecture and concurrency
Apex Hammer runs as a cloud service: scenarios use Apex, while generators and orchestration are vendor-managed.
