Example 1 with ArgumentConverter

use of org.junit.jupiter.params.converter.ArgumentConverter in project junit5 by junit-team.

the class ParameterizedTestParameterResolver method resolveParameter.

@Override
public Object resolveParameter(ParameterContext parameterContext, ExtensionContext extensionContext) throws ParameterResolutionException {
    Object argument = arguments[parameterContext.getIndex()];
    Parameter parameter = parameterContext.getParameter();
    Optional<ConvertWith> annotation = AnnotationUtils.findAnnotation(parameter, ConvertWith.class);
    // @formatter:off
    ArgumentConverter argumentConverter = annotation.map(ConvertWith::value).map(clazz -> (ArgumentConverter) ReflectionUtils.newInstance(clazz)).map(converter -> AnnotationConsumerInitializer.initialize(parameter, converter)).orElse(DefaultArgumentConverter.INSTANCE);
    // @formatter:on
    try {
        return argumentConverter.convert(argument, parameterContext);
    } catch (Exception ex) {
        throw new ParameterResolutionException("Error resolving parameter at index " + parameterContext.getIndex(), ex);
    }
}
