testPrettyPrinter

public static <N extends de.monticore.ast.ASTNode>
void testPrettyPrinter(String model,
 de.monticore.antlr4.MCConcreteParser parser,
 PrettyPrinterTester.ParseFunction<N> parseFunc,
 Function<N,String> prettyPrintFunc,
 Predicate<String> additionalCheck)

Tests pretty printing. The Model is parsed, pretty printed and parsed again. The AST of the pretty printed model is expected to be comparable to the AST of the original model.

Type Parameters:

N - the type of the ASTNode after parsing

Parameters:

model - the model to be pretty printed

parser - the parser used to convert the model to an AST

parseFunc - the concrete parse function used, e.g., myParser::parse_StringMyNonTerminal

prettyPrintFunc - the actual pretty printing operation, e.g., ast -> MyMill.prettyPrint(ast, true)

additionalCheck - additional check on the pretty printed String
