JarCastingPrototest
The small library for creating object by class and fill it random data for easy testing.
From 1.0.2.0 version, you can use annotation with Junit5 extension.
Requirements
- JDK >= 8
- Maven >= 3
Maven configuration
Add the Maven dependency:
<dependency>
<groupId>com.github.nmuzhichin</groupId>
<artifactId>prototest</artifactId>
<version>1.0.2.0</version>
<scope>test</scope>
</dependency>
How to use
Entry point is Prototest class that has methods for creating lazy pipeline.
Method execute() run pipeline and take ready to use object.
Sample
- Generate empty pipeline and run it:
final Empty empty = Prototest.empty().execute();
- Now take by class:
final SomethingClass newObj = Prototest.now(SomethingClass.class);
- Uses flatten, identity, logs methods:
final SomethingClass obj = Prototest
.configure()
.fromClass(SomethingClass.class)
.flatten(it -> Prototest.configure()
.fromClass(SimpleObject.class)
.side(q -> q.setName(it)))
.log()
.execute();
- Complex generate with configuration and listeners:
final TypeListener listener = type -> String.class == type ? RandomStringUtils.randomNumeric(12) : null;
Prototest
.configure(config -> config.addImplementationFor(CustomInterface.class, new CustomInterfaceAbstractImpl("123")))
.registerContainerListener(ContainerPhase.OBJECT_EMMIT, System.out::println)
.registerTypesListener(TypePhase.CONSTRUCTOR_ARGS, listener)
.fromClass(ComplexObject.class)
.log()
.assertions(it -> it.as().nonNull())
.execute();
Annotation sample (from 1.0.2.0)
@ExtendWith(PrototestExtension.class)
@PrototestImplementations({
@PrototestImplementation(className = String.class, value = "123456"),
@PrototestImplementation(className = Integer.class),
@PrototestImplementation(className = Byte.class, value = "123"),
})
public class ExtensionTest {
private final ComplexObject object;
@AsPrototest
private ComplexObject object2;
public ExtensionTest(@AsPrototest final ComplexObject object) {
this.object = object;
}
@Test
void t(@AsPrototest(DefaultConfig.DEFAULT) ComplexObject methodArg) {
Assertions.assertNotNull(methodArg);
Assertions.assertNotNull(object);
Assertions.assertNotNull(object2);
}
}
