public class MockConsole
extends PrintStream

A capturing PrintStream that allows you to easily capture console output.

Stores output into an internal ByteArrayOutputStream. Note that this means you could run into memory constraints if you heavily use this class.

Typically used in conjunction with the RestClient.Builder.console(PrintStream) to capture console output for testing purposes.

Example:

// A simple REST API that echos a posted bean. @Rest public class MyRest extends BasicRestObject { @RestPost("/bean") public Bean postBean(@Content Bean bean) { return bean; } } // Our mock console. MockConsole console = MockConsole.create(); // Make a call against our REST API and log the call. MockRestClient .create(MyRest.class) .json5() .logRequests(DetailLevel.FULL, Level.SEVERE) .logToConsole() .console(console) .build() .post("/bean", bean) .run(); console.assertContents().is( "", "=== HTTP Call (outgoing) ======================================================", "=== REQUEST ===", "POST http://localhost/bean", "---request headers---", " Accept: application/json5", "---request entity---", " Content-Type: application/json5", "---request content---", "{f:1}", "=== RESPONSE ===", "HTTP/1.1 200 ", "---response headers---", " Content-Type: application/json", "---response content---", "{f:1}", "=== END =======================================================================", "" );
