This repository contains a Java implementation of Weighted Pushdown Systems. Additionally, it contains an implementation of Boomerang and IDEal based on a Weighted Pushdown System.
All projects inside this repository are pushed to GitHub's Maven repository for every release.
To include a dependency from this repository to your poject, you first have to add the repository to your pom file:
<dependencies>
<dependency>
<groupId>de.fraunhofer.iem</groupId>
<artifactId>WPDS</artifactId>
<version>3.0.5</version>
</dependency>
</dependencies>
<repositories>
<repository>
<id>CodeShield-Security</id>
<url>https://maven.pkg.github.com/CodeShield-Security/SPDS/</url>
</repository>
</repositories>
To build and install WPDS into your local repository, run
mvn clean install -DskipTests
in the root directory of this git repository. If you do not want to skip the test cases, remove the last flag.
Boomerang code examples can be found here. Code examples for IDEal are given here.
The projects Boomerang and IDEal contain JUnit test suites. As for JUnit, the test methods are annotated with @Test and can be run as normal JUnit tests. However, these methods are not executed but only statically analyzed. When one executes the JUnit tests, the test method bodies are supplied as input to Soot and a static analysis is triggered. All this happens in JUnit's @Before test time. The test method itself is never run, may throw NullPointerExceptions or may not even terminate.
If the static analysis succeeded, JUnit will officially label the test method as skipped. However, the test will not be labeled as Error or Failure. Even though the test was skipped, it succeeded. Note, JUnit outputs a message:
org.junit.AssumptionViolatedException: got: <false>, expected: is <true>
This is ok! The test passed!
