This introduces the concept of validation errors, where we have a high
level validation error which wraps a more detailed error message.
The higher level `ValidationError` is set up in the generated files, much
like the `NotFoundError` and `ConstraintError` and is accompanied by an
`IsValidationError` check method. Thus, it can be used as follows:
```go
t, err := tx.Team.Create().SetName(input.Name).Save(ctx)
if ent.IsValidationError(err) {
// handle validation error response
}
```
entc integration tests
Regenerating new templates
If you edited one of the files in entc/gen/template or entc/load/template,
run the following command to from entc directory:
go generate ./...
Running the integration tests
docker-compose -f compose/docker-compose.yaml up -d --scale test=0
go test
Use the -run flag for running specific test or set of tests. For example:
go test -run=MySQL
go test -run=SQLite/Sanity
