Examples of org.springframework.mock.env.MockPropertySource

org.springframework.mock.env.MockPropertySource
Simple {@link PropertySource} implementation for use in testing. Acceptsa user-provided {@link Properties} object, or if omitted during construction,the implementation will initialize its own. The {@link #setProperty} and {@link #withProperty} methods are exposed forconvenience, for example:
```
 {@code PropertySource source = new MockPropertySource().withProperty("foo", "bar");}
```
