2. ImportBeanDefinitionRegistrard 구현체 생성
<- 해당 구현체는 Spring @Configration이 선언된 클래스에 대해서 실행된다.
3. 테스트를 진행할 Annotation Interface를 생성
4.TestContext객체생성
테스트 클래스들은 Mybatis mapperScan을 기반으로 생성하였음.
TestScan 클래스
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@Documented
@Import(TestSannerRegistarar.class)
public @interface TestScan {
String[] value() default {};
String[] basePackages() default {};

Class<? extends Annotation> annotationClass() default Annotation.class;
Class<?> markerInterface() default Class.class;
String sqlSessionTemplateRef() default "";
String sqlSessionFactoryRef() default "";
}
TestScannerRegistarar 클래스

TestMapper 클래스
