Validation

This is a library used to validate java object against a set of validation rules.

This is inspired by mockito and hamcrest so it should be familiar to use if you know those tools.

Limitations

It requires that the objects follow the java bean convention with a field and a getter is present.

How to use

build the project and import it with maven.

<dependency>
  <groupId>com.github.ingarabr.validator</groupId>
  <artifactId>validation</artifactId>
  <version>{validation.version}</version>
</dependency>

Building up a rule

First we need to specify the field we need:

field(SomeBean.class).getValue();

Now we can add a validation condition to it:

validation(field(SomeBean.class).getValue(), mustHaveValue());

This can be chain into other validation conditions like and, or etc.

To verify that an object is valid against the validation condition the API expose two method. isValidateObject that gives a boolean result and validateObject that gives a set of violations. The set it empty if no validation condition is violated.

Validation validation = validation(field(SomeBean.class).getValue(), hasOneOfTheValues("foo1", "foo2"));
boolean isValid = fieldCondition.isValidateObject(new SomeBean().value("foo1"));

See the test for more example of usage.
