如何将rest-assured日志变成可打印的文本文件[英] How to get rest-assured log into something printable in a text file

问题描述

I'm working into a method trying to change the default rest-assured log (which goes to the console) to a file using log4j.

It's a JUnit project which methods finally call to a REST facade, which have methods like this one.

 private ResponseSpecification responseSpecification(RequestSpecification requestSpecification, Matcher matcher, int statusCode) {
        ResponseSpecification responseSpecification = requestSpecification.expect().statusCode(StatusCode).body(".", is(matcher));
        if (log) {
            responseSpecification = responseSpecification.log().all();
        }
        return responseSpecification;
    }

Following the official doc, I've changed the method like this:

private ResponseSpecification responseSpecification(RequestSpecification requestSpecification, Matcher matcher, int statusCode) {
    final StringWriter writer = new StringWriter();
    final PrintStream captor = new PrintStream(new WriterOutputStream(writer), true);
    ResponseSpecification responseSpecification = requestSpecification.filter(logResponseTo(captor)).expect().statusCode(statusCode).body(".", is(matcher));
    System.out.println("writer = " + writer.toString() + " <-");
    return responseSpecification;
}

But writer.toString() prints always a void string (the old implementation works fine). Maybe I'm doing something wrong, but what? :(

I need to get something printable which can be managed by log4j, in this or other way.

Can anyone help me?

I've just solved the problem writing this into the RestSuite.setUp() method

RestAssured.config = config().logConfig(new LogConfig(defaultPrintStream));

and keeping intact the old code.

private ResponseSpecification responseSpecification(RequestSpecification requestSpecification, Matcher matcher, int statusCode) {
    ResponseSpecification responseSpecification = requestSpecification.expect().statusCode(StatusCode).body(".", is(matcher));
    if (log) {
        responseSpecification = responseSpecification.log().all();
    }
    return responseSpecification;
}

I hope it can help to someone in a future.

Might be useful too: Here a class which redirects the restAssured log() calls to a supplied logger:

import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintStream;
import org.slf4j.Logger;

/**
 * A wrapper class which takes a logger as constructor argument and offers a PrintStream whose flush
 * method writes the written content to the supplied logger (debug level).
 * <p>
 * Usage:<br> 
 * initializing in @BeforeClass of the unit test:
 * <pre>
 *          ToLoggerPrintStream loggerPrintStream = new ToLoggerPrintStream( myLog );
 *          RestAssured.config = RestAssured.config().logConfig(
 *                                 new LogConfig( loggerPrintStream.getPrintStream(), true ) );
 * </pre>
 * will redirect all log outputs of a ValidatableResponse to the supplied logger:
 * <pre>
 *             resp.then().log().all( true );

PrintStream fileOutPutStream = new PrintStream(new File("somefile.txt"));
RestAssured.config = config().logConfig(new LogConfig().defaultStream(fileOutPutStream)); 

Use a printStream to point to a file & give a filename you want to print the log. Put the above code in your setup method for the tests & then just call log on your RequestSpecification instance as below

requestSpecification.log().all();
