Description copied from class: AnnotationBasedArgumentsProvider

The returned Stream will be properly closed by the default implementation of AnnotationBasedArgumentsProvider.provideArguments(ParameterDeclarations, ExtensionContext), making it safe to use a resource such as Files.lines().

Overrides:

findFactoryMethod

private static Method findFactoryMethod(Class<?> testClass,
 Optional<Method> testMethod,
 String factoryMethodName)

looksLikeAFullyQualifiedMethodName

private static boolean looksLikeAFullyQualifiedMethodName(String factoryMethodName)

findFactoryMethodByFullyQualifiedName

static Method findFactoryMethodByFullyQualifiedName(Class<?> testClass,
 Optional<Method> testMethod,
 String fullyQualifiedMethodName)

findFactoryMethodBySimpleName

private static Method findFactoryMethodBySimpleName(Class<?> clazz,
 Optional<Method> testMethod,
 String factoryMethodName)

Find the factory method by searching for all methods in the given clazz with the desired factoryMethodName which have return types that can be converted to a Stream, ignoring the testMethod itself as well as any @Test, @TestTemplate, or @TestFactory methods with the same name.

Returns:

the single factory method matching the search criteria

Throws:

org.junit.platform.commons.PreconditionViolationException - if the factory method was not found or multiple competing factory methods with the same name were found

isTestMethod

private static boolean isTestMethod(Method candidate)

validateFactoryMethod

private static Method validateFactoryMethod(Method factoryMethod,
 Object testInstance)
