# Web integration testsThese tests are not hermetic, and use the actual Flutter SDK. Whilethey don't require actual devices, they run `flutter_tester` to test
```These tests are expensive to run and do not give meaningful coverageinformation for the flutter tool (since they are black-box tests thatrun the tool as a subprocess, rather than being unit tests). For thisreason, they are in a separate shard when running on continuousintegration and are not run when calculating coverage.
