## Running the Correctness Test

*Note*: currently the assertions in this test fail when running it in a local environment because the [test expects a large population](https://github.com/world-federation-of-advertisers/cross-media-measurement/blob/v0.5.29/src/test/kotlin/org/wfanet/measurement/integration/k8s/SyntheticGeneratorCorrectnessTest.kt#L99) and the local EDP simulators are [configured to use a small population](https://github.com/world-federation-of-advertisers/cross-media-measurement/blob/v0.5.29/src/main/k8s/local/edp_simulators.cue#L44). For the test to pass, it needs to be switched to population small.

nit: rephrase this to include clear instructions on what code changes to make to get the test to pass

Additional context would be that the local EDP simulators use a small population as single machines tend not to have enough memory to handle large populations. If they have enough RAM and are willing to wait longer for the test to run, they can technically swap the simulators to use the large pop instead of swapping the test to use the small one. We don't need to include instructions for that though :)
