+# validator.js test for JetStream
+
+Measures the performance of the validator.js library by running the core test suite.
+
+## Build Instructions
+
+```bash
+# install required node packages.
+npm ci
+# build the workload, output is ./dist
+npm run build
+```
+
+## Workloads
+
+The workload is a modified copy of the validator.js [test suite](https://github.com/validatorjs/validator.js/tree/master/test).
+Several files are combined together and contents copied to the `runTest` method.
+
+Modifications to the original:
+- Any tests that depend on node internal values have been removed.
+- Date constructions with an arg-array differs between browser and thus they
+  are replaced by direct arguments.
+- Direct calls to validater.xzy() are replaced with validatorjs.xzy() to not
+  conflict with the default argument to the mock test() method.
