Make your own Java Annotations

Annotations, a form of metadata, provide data about a program that is not part of the program itself. Annotations have no direct effect on the operation of the code they annotate. Annotations have been a powerful part of Java, but most times we tend to use them rather than create them.

Passing Data to Future Steps in Spring Batch

An ExecutionContext is a set of key-value pairs containing information that is scoped to either StepExecution or JobExecution. Spring Batch persists the ExecutionContext, which helps in cases where you want to restart a batch run (e.g., when a fatal error has occurred, etc.). All that is needed is to put any object to be shared between steps into the context and the framework will take care of the rest. After restart, the values from the prior ExecutionContext are restored from the database and applied.

Mockito doesn’t give a Hangover – Java Unit Tests

Mockito is a mocking framework. It is a Java-based library used to create simple and basic test APIs for performing unit testing of Java applications. It internally uses the Java Reflection API to generate mock objects for a specific interface. Mockito is in top 10 Java library across all libraries, not only the testing tools.

JUnit Annotations with Example
