RevAjaxMutator

Written by Yuta Maezawa and greatest contributors

Description

A tool for "mutation testing" and "automated program repair" of Ajax Web Applications

Let's Get Started

Maven Settings

Add our in-house Maven repository.

<repositories>
	<repository>
		<id>jp.mzw.mvn-repo</id>
		<url>http://mvn-repo.mzw.jp</url>
	</repository>
</repositories>

Then, RevAjaxMutator is available in a project under test.

<dependency>
	<groupId>jp.mzw.revajaxmutator</groupId>
	<artifactId>RevAjaxMutator</artifactId>
	<version>0.1</version>
</dependency>

Configuration

Deploy localenv.properties on the class path.

chrome_bin       = /path/to/google-chrome-stable
chromedriver_bin = /path/to/chromedriver

firefox_bin      = /path/to/firefox
geckodriver_bin  = /path/to/geckodriver-0.15.0/geckodriver

phantomjs_bin    = /path/to/phantomjs-2.1.1-linux-x86_64/bin/phantomjs

 #selenium_hub_ip=http://localhost:5000

proxy_ip         = 127.0.0.1
proxy_port       = 8080

timeout          = 5

RevAjaxMutator will use the driver in the order above.

In addition, deploy another property file for an application under test.

url 			    	  	  = http://mzw.jp:80/yuta/research/ram/example/after/faulty/quizzy/main.php

path_to_js_file 		  = quizzy/quizzy.js
path_to_html_file 		= main.php
path_to_testcase_file = src/main/java/jp/mzw/revajaxmutator/test/quizzy/QuizzyTest.java

ram_record_dir        = jscover/quizzy
jscover_report_dir    = record/quizzy

Setting up Selenium-grid (optional)

To use Selenium-grid (distributed processing), uncomment selenium_hub_ip from localenv.properties and change the value as appropriate. Selenium-grid also requires a "hub" machine and the "worker" machines properly setup and configured.

To setup the hub, input the following into an available machine:

$ docker pull selenium/hub
$ docker run -d -p 5000:4444 --name selenium-hub -P selenium/hub

For each worker machine:

(Remove the "--env SE_OPTS" parameter if hub is on the same machine as the worker.)
(Remove the "--add-host" parameter if you are not using the examples from "ram-test".)
$ docker run -d -P --name selenium-worker \
  --add-host ram-test.mzw.jp:172.17.0.1 \
  --env HUB_PORT_4444_TCP_ADDR=172.17.0.1 \
  --env HUB_PORT_4444_TCP_PORT=5000 \
  --env SE_OPTS="-host XX.XX.XX.XX -port YYYY"

CTRL+P, CTRL+Q

Test Case

Test cases need to be extended from jp.mzw.revajaxmutator.test.WebAppTestBase. Otherwise, you need to instantiate our record/rewrite proxy server manually.

import jp.mzw.revajaxmutator.test.WebAppTestBase;
public class YourAppTest extends WebAppTestBase {...

Example test cases can be found at: https://gitlab.mzw.jp/yuta/ram-test-2

Run

To run RevAjaxMutator against a particular project (in this case, Roundcubemail from ram-test-2) :

records webpage files locally -- needed for mutating files and testing the results:
$ java -cp ${class-path} jp.mzw.revajaxmutator.CLI \
    record \
    jp.mzw.revajaxmutator.test.roundcubemail.RoundcubemailConfig \
    jp.mzw.revajaxmutator.test.roundcubemail.RoundcubemailTest

generate test coverage -- speeds up mutation:
$ java -cp ${class-path} jp.mzw.revajaxmutator.CLI \
    test-each \
    jp.mzw.revajaxmutator.test.roundcubemail.RoundcubemailConfig \
    jp.mzw.revajaxmutator.test.roundcubemail.RoundcubemailTest
    
try to automatically find the correct mutation that fixes the failing test:
$ java -cp ${class-path} jp.mzw.revajaxmutator.CLI \
    validate-concurrently \
    jp.mzw.revajaxmutator.test.roundcubemail.RoundcubemailConfig \
    jp.mzw.revajaxmutator.test.roundcubemail.RoundcubemailTest

Enjoy RevAjaxMutator!
