Document

Create a new MockPropertySource named #MOCK_PROPERTIES_PROPERTY_SOURCE_NAME and backed by the given Properties object.

Usage

From source file:io.bitsquare.app.BitsquareEnvironmentTests.java

@Test
public void testPropertySourcePrecedence() {
    PropertySource commandlineProps = new MockPropertySource(BITSQUARE_COMMANDLINE_PROPERTY_SOURCE_NAME)
            .withProperty("key.x", "x.commandline");

    PropertySource filesystemProps = new MockPropertySource(BITSQUARE_FILESYSTEM_PROPERTY_SOURCE_NAME)
            .withProperty("key.x", "x.env").withProperty("key.y", "y.env");

    ConfigurableEnvironment env = new BitsquareEnvironment(commandlineProps) {
        @Override//from  www  .  jav a2 s.  co  m
        PropertySource<?> filesystemProperties() {
            return filesystemProps;
        }
    };
    MutablePropertySources propertySources = env.getPropertySources();

    assertThat(propertySources.precedenceOf(named(BITSQUARE_COMMANDLINE_PROPERTY_SOURCE_NAME)), equalTo(0));
    assertThat(propertySources.precedenceOf(named(SYSTEM_PROPERTIES_PROPERTY_SOURCE_NAME)), equalTo(1));
    assertThat(propertySources.precedenceOf(named(SYSTEM_ENVIRONMENT_PROPERTY_SOURCE_NAME)), equalTo(2));
    assertThat(propertySources.precedenceOf(named(BITSQUARE_FILESYSTEM_PROPERTY_SOURCE_NAME)), equalTo(3));
    assertThat(propertySources.precedenceOf(named(BITSQUARE_CLASSPATH_PROPERTY_SOURCE_NAME)), equalTo(4));
    assertThat(propertySources.precedenceOf(named(BITSQUARE_DEFAULT_PROPERTY_SOURCE_NAME)), equalTo(5));
    assertThat(propertySources.size(), equalTo(6));

    assertThat(env.getProperty("key.x"), equalTo("x.commandline")); // commandline value wins due to precedence
    assertThat(env.getProperty("key.y"), equalTo("y.env")); // env value wins because it's the only one available
}
