Injecting test doubles instead of beans using Springockito

In this recipe, we will replace an existing bean with a test double using Springockito's annotations. (refer to Springockito core at https://bitbucket.org/kubek2k/springockito/wiki/Home, Springockito annotations at https://bitbucket.org/kubek2k/springockito/wiki/springockito-annotations).

Getting ready

To add Springockito annotations to your classpath, refer to the following dependency configurations. The configuration for Gradle is as follows:

testCompile 'org.kubek2k:springockito-annotations:1.0.9'
and Maven
<dependency>
	<groupId>org.kubek2k</groupId>
	<artifactId>springockito-annotations</artifactId>
	<version>1.0.9</version>
</dependency>            

Our system under test is the person's tax transferring system, as shown in the following code:

public class TaxTransferer {

    private final TaxService taxService;

    public TaxTransferer(TaxService taxService) {
        this.taxService...
