Immutable type​

ConstructorPropertiesIntrospector​

0. Prerequisites​

Should satisfy one of below preconditions

  • record type
  • any constructors with @ConstructorProperties
Tip

Multiple constructors with record would be instantiated by constructor with @ConstructorProperties

1. Altering objectIntrospector option​

FixtureMonkey fixtureMonkey = FixtureMonkey.builder()
    .objectIntrospector(ConstructorPropertiesArbitraryIntrospector.INSTANCE)
    .build();

FactoryMethodArbitraryIntrospector​

0. Prerequisites​

  • static factory method

1. Altering objectIntrospector option​

FixtureMonkey fixtureMonkey = FixtureMonkey.builder()
    .objectIntrospector(FactoryMethodArbitraryIntrospector.INSTANCE)
    .build();

JacksonArbitraryIntrospector​

Tip

This practice should add extra module because it depends on third-party library Jackson

0. Prerequisites​

Type should be serializable/deserializable by Jackson

1. Adding dependency​

testImplementation("com.navercorp.fixturemonkey:fixture-monkey-jackson:0.6.12")
<dependency>
  <groupId>com.navercorp.fixturemonkey</groupId>
  <artifactId>fixture-monkey-jackson</artifactId>
  <version>0.6.12</version>
  <scope>test</scope>
</dependency>

2. Altering objectIntrospector option​

If you have custom ObjectMapper​
FixtureMonkey fixtureMonkey = FixtureMonkey.builder()
    .plugin(new JacksonPlugin(objectMapper))
    .build();
If you DON'T have a custom ObjectMapper​
FixtureMonkey fixtureMonkey = FixtureMonkey.builder()
    .plugin(new JacksonPlugin())
    .build();

FieldReflectionArbitraryIntrospector​

0. Prerequisites​

  1. No args constructor
  2. Getter / Setter

1. Altering objectIntrospector option​

FixtureMonkey fixtureMonkey = FixtureMonkey.builder()
    .objectIntrospector(FieldReflectionArbitraryIntrospector.INSTANCE)
    .build();

BeanArbitraryIntrospector​

Tip

BeanArbitraryIntrospector is default objectIntrospector

0. Prerequisites​

  1. No args constructor
  2. Setter
