use of liquibase.configuration.ConfigurationValueConverter in project liquibase by liquibase.

the class TestSystem method getConfiguredValue.

/**
 * Returns the configured value for the given propertyName. It will check (in priority order):

 * <li>properties set directly on this object</li>
 * <li>liquibase.sdk.testSystem.[name].[profile(s)].propertyName in the order the profiles are set on this object</li>
 * <li>liquibase.sdk.testSystem.[name].propertyName</li>
 * <li>liquibase.sdk.testSystem.default.propertyName</li>
 * </ol>
 * <br>
 * If a value is not found, it will return null or throw an {@link UnexpectedLiquibaseException} if 'required' is true.
