use of org.junit.platform.commons.util.ReflectionUtils in project junit5 by junit-team.

the class ParameterizedTestExtension method provideTestTemplateInvocationContexts.

    Method templateMethod = context.getRequiredTestMethod();
    ParameterizedTestNameFormatter formatter = createNameFormatter(templateMethod);
    AtomicLong invocationCount = new AtomicLong(0);
    // @formatter:off
    return findRepeatableAnnotations(templateMethod, ArgumentsSource.class).stream().map(ArgumentsSource::value).map(ReflectionUtils::newInstance).map(provider -> AnnotationConsumerInitializer.initialize(templateMethod, provider)).flatMap(provider -> arguments(provider, context)).map(Arguments::get).map(arguments -> consumedArguments(arguments, templateMethod)).map(arguments -> createInvocationContext(formatter, arguments)).peek(invocationContext -> invocationCount.incrementAndGet()).onClose(() -> Preconditions.condition(invocationCount.get() > 0, () -> "Configuration error: You must provide at least one argument for this @" + ParameterizedTest.class.getSimpleName()));
// @formatter:on
