Tests a format-agnostic normalizer.

@dataProvider providerTestCustomBooleanNormalization

Parameters

string[] $test_modules: The test modules to install.

string $format: The format to test. (NULL results in the format-agnostic normalization.)

FieldItemSerializationTest

Test field level normalization process.
