Class DefaultEnvironment

java.lang.Object
org.kiwiproject.base.DefaultEnvironment
All Implemented Interfaces:
KiwiEnvironment
public class DefaultEnvironment extends Object implements KiwiEnvironment
A default implementation of the KiwiEnvironment interface. Normal usage is to define a private KiwiEnvironment and initialize it to a new instance of this class, for example in a constructor:

Then wherever you would normally call things like System.currentTimeMillis(), use the corresponding method from KiwiEnvironment instead, e.g. env.currentTimeMillis().

For testing environment-related code, inject a mock instance via a constructor. A common pattern is to provide a separate constructor that accepts a KiwiEnvironment specifically for test code to use; often this should be made package-private (default scope). Other constructors will generally call this constructor. For example: 

  private KiwiEnvironment env;

  public Foo() {
      this(new DefaultKiwiEnvironment());
  }

  Foo(KiwiEnvironment env) {
      this.env = env;
  }
