DataTestSetup class final

What makes a test context the slice of a @DataTest: the data beans of an application and the starter's auto-configuration, an in-memory database, and nothing else.

It gives springBootTest two things for the application it describes: properties, which leave out the auto-configuration of the other starters, and an initializer, which leaves out the application's other beans (DataTestSlice) and replaces its databases (TestDatabase). The generated code of a @DataTest class does it; in a test written as functions, do it by hand, and wrap each test in runInTestTransaction:

void main() {
  final data = DataTestSetup(springApplication);
  final app = springBootTest(
    springApplication,
    properties: data.properties,
    initializers: [data.initializer],
  );

  test('saves a book', () => runInTestTransaction(app.context, () async {
    await app.getBean<BookRepository>().save(Book(title: 'Dune'));
  }));
}

Spring (Java): the annotations of @DataJdbcTest: @TypeExcludeFilters, @AutoConfigureDataJdbc, @AutoConfigureTestDatabase and @Transactional.

Constructors

DataTestSetup(SpringApplication application, {List<Type> include = const [], bool replaceDatabase = true})

The slice of application: its data beans, those of the types in include, and the databases replaced unless replaceDatabase is false.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

include → List<Type>

The beans added to the slice by the types of their classes.

final

initializer → ApplicationContextInitializer

The initializer of the slice, for springBootTest(initializers:): it replaces the databases and leaves out the beans, in each context the test starts.

no setter

properties → Map<String, Object?>

The properties of the slice: spring.autoconfigure.exclude names the auto-configuration modules of the application that are not autoConfigurationNames (the web, cache, security... starters).

no setter

replaceDatabase → bool

Whether the databases of the properties are replaced.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Properties

autoConfigurationNames → List<String>

The names of the auto-configuration modules a slice keeps: the core one, logging and the data starter's own.
