+{: .no_toc}
+
+- TOC
+{:toc}

+
+The process of integrating a project written in Java or any other language
+running on the Java Virtual Machine (JVM) with OSS-Fuzz is very similar to the
+general
+[Setting up a new project]({{ site.baseurl }}/getting-started/new-project-guide/)
+process. The key specifics of integrating a JVM project are outlined below.
+
+## Jazzer
+
+Java fuzzing in OSS-Fuzz depends on
+[Jazzer](https://github.com/CodeIntelligenceTesting/jazzer), which is
+pre-installed on the OSS-Fuzz base docker images. As Jazzer operates directly
+on the bytecode level, it can be applied to any project written in a JVM-based
+language. More information on how Jazzer fuzz targets look like can be found in
+its
+[README's Usage section](https://github.com/CodeIntelligenceTesting/jazzer#usage).
+
+## Project files
+
+### Example project
+
+We recommend viewing
+[json-sanitizer](https://github.com/google/oss-fuzz/tree/master/projects/json-sanitizer)
+as an example of a simple Java-only fuzzing project. Additional examples,
+including one for a Java project with native dependencies, are part of the
+[java-example](https://github.com/google/oss-fuzz/tree/master/projects/java-example)
+project.
+
+### project.yaml
+
+The `language` attribute must be specified as follows:
+
+```yaml
+language: jvm
+```
+
+The only supported fuzzing engine is libFuzzer (`libfuzzer`). So far the only
+supported sanitizers are AddressSanitizer (`address`) and
+UndefinedBehaviorSanitizer (`undefined`). For pure Java projects, specify
+just `address`:
+
+```yaml
+fuzzing_engines:
+  - libfuzzer
+sanitizers:
+  - address
+```
+
+### Dockerfile
+
+The Dockerfile should start by `FROM gcr.io/oss-fuzz-base/base-builder-jvm`
+
+The OSS-Fuzz base Docker images already come with OpenJDK 15 pre-installed. If
+you need Maven to build your project, you can install it by adding the following
+line to your Dockerfile:
+
+```docker
+RUN apt-get update && apt-get install -y maven
+```
+
+Apart from this, you should usually not need to do more than to clone the
+project, set a `WORKDIR`, and copy any necessary files, or install any
+project-specific dependencies here as you normally would.
+
+### Fuzzers
+
+In the simplest case, every fuzzer consists of a single Java file with a
+filename matching `*Fuzzer.java` and no `package` directive. An example fuzz
+target could thus be a file `ExampleFuzzer.java` with contents:
+
+```java
+public class ExampleFuzzer {
+    public static void fuzzerTestOneInput(byte[] input) {
+        ...
+        // Call a function of the project under test with arguments derived from
+        // input and throw an exception if something unwanted happens.
+        ...
+    }
+}
+```
+
+### build.sh
+
+For JVM projects, `build.sh` does need some more significant modifications
+over C/C++ projects. Below is an annotated example build script for a
+Java-only project with single-file fuzz targets as described above:
+
+```sh
+# Step 1: Build the project
+
+# Build the project .jar as usual, e.g. using Maven.
+mvn package
+# In this example, the project is built with Maven, which typically includes the
+# project version into the name of the packaged .jar file. The version can be
+# obtained as follows:
+CURRENT_VERSION=$(mvn org.apache.maven.plugins:maven-help-plugin:3.2.0:evaluate \
+-Dexpression=project.version -q -DforceStdout)
+# Copy the project .jar into $OUT under a fixed name.
+cp "target/sample-project-$CURRENT_VERSION.jar" $OUT/sample-project.jar
+
+# Specify the projects .jar file(s), separated by spaces if there are multiple.
+PROJECT_JARS="sample-project.jar"
+
+# Step 2: Build the fuzzers (should not require any changes)
+
+# The classpath at build-time includes the project jars in $OUT as well as the
+# Jazzer API.
+BUILD_CLASSPATH=$(echo $PROJECT_JARS | xargs printf -- "$OUT/%s:"):$JAZZER_API_PATH
+
+# All .jar and .class files lie in the same directory as the fuzzer at runtime.
+RUNTIME_CLASSPATH=$(echo $PROJECT_JARS | xargs printf -- "\$this_dir/%s:"):\$this_dir
+
+for fuzzer in $(find $SRC -name '*Fuzzer.java'); do
+  fuzzer_basename=$(basename -s .java $fuzzer)
+  javac -cp $BUILD_CLASSPATH $fuzzer
+  cp $SRC/$fuzzer_basename.class $OUT/
+
+  # Create an execution wrapper that executes Jazzer with the correct arguments.
+  echo "#!/bin/bash
+# LLVMFuzzerTestOneInput for fuzzer detection.
+this_dir=\$(dirname \"\$0\")
+if [[ \"\$@\" =~ (^| )-runs=[0-9]+($| ) ]]; then
+  mem_settings='-Xmx1900m:-Xss900k'
+else
+  mem_settings='-Xmx2048m:-Xss1024k'
+fi
+LD_LIBRARY_PATH=\"$JVM_LD_LIBRARY_PATH\":\$this_dir \
+\$this_dir/jazzer_driver --agent_path=\$this_dir/jazzer_agent_deploy.jar \
+--cp=$RUNTIME_CLASSPATH \
+--target_class=$fuzzer_basename \
+--jvm_args=\"\$mem_settings:-Djava.awt.headless=true\" \
+\$@" > $OUT/$fuzzer_basename
+  chmod +x $OUT/$fuzzer_basename
+done
+```
+
+The [java-example](https://github.com/google/oss-fuzz/blob/master/projects/java-example/build.sh)
+project contains an example of a `build.sh` for Java projects with native
+libraries.
+
+## FuzzedDataProvider
+
+Jazzer provides a `FuzzedDataProvider` that can simplify the task of creating a
+fuzz target by translating the raw input bytes received from the fuzzer into
+useful primitive Java types. Its functionality is similar to
+`FuzzedDataProviders` available in other languages, such as
+[Python](https://github.com/google/atheris#fuzzeddataprovider) and
+[C++](https://github.com/google/fuzzing/blob/master/docs/split-inputs.md).
+
+On OSS-Fuzz, the required library is available in the base docker images under
+the path `$JAZZER_API_PATH`, which is added to the classpath by the example
+build script shown above. Locally, the library can be obtained from
+[Maven Central](https://search.maven.org/search?q=g:com.code-intelligence%20a:jazzer-api).
+
+A fuzz target using the `FuzzedDataProvider` would look as follows:
+
+```java
+import com.code_intelligence.jazzer.api.FuzzedDataProvider;
+
+public class ExampleFuzzer {
+    public static void fuzzerTestOneInput(FuzzedDataProvider data) {
+        int number = data.consumeInt();
+        String string = data.consumeRemainingAsString();
+        // ...
+    }
+}
+```
+
+For a list of convenience methods offered by `FuzzedDataProvider`, consult its
+[javadocs](https://codeintelligencetesting.github.io/jazzer-docs/jazzer-api/com/code_intelligence/jazzer/api/FuzzedDataProvider.html).

+# Integrating a Python project
+{: .no_toc}
+
+- TOC
+{:toc}
+---
+
+
+The process of integrating a project written in Python with OSS-Fuzz is very
+similar to the general
+[Setting up a new project]({{ site.baseurl }}/getting-started/new-project-guide/)
+process. The key specifics of integrating a Python project are outlined below.
+
+## Atheris
+
+Python fuzzing in OSS-Fuzz depends on
+[Atheris](https://github.com/google/atheris). Fuzzers will depend on the
+`atheris` package, and dependencies are pre-installed on the OSS-Fuzz base
+docker images.
+
+## Project files
+
+### Example project
+
+We recommend viewing [ujson](https://github.com/google/oss-fuzz/tree/master/projects/ujson) as an
+example of a simple Python fuzzing project, with both plain-Atheris and
+Atheris + Hypothesis harnesses.
+
+### project.yaml
+
+The `language` attribute must be specified.
+
+```yaml
+language: python
+```
+
+The only supported fuzzing engine is libFuzzer (`libfuzzer`). The supported
+sanitizers are AddressSanitizer (`address`) and
+UndefinedBehaviorSanitizer (`undefined`). These must be explicitly specified.
+
+```yaml
+fuzzing_engines:
+  - libfuzzer
+sanitizers:
+  - address
+  - undefined
+```
+
+### Dockerfile
+
+The Dockerfile should start by `FROM gcr.io/oss-fuzz-base/base-builder-python`
+
+Because most dependencies are already pre-installed on the images, no
+significant changes are needed in the Dockerfile for Python fuzzing projects.
+You should simply clone the project, set a `WORKDIR`, and copy any necessary
+files, or install any project-specific dependencies here as you normally would.
+
+### build.sh
+
+For Python projects, `build.sh` does need some more significant modifications
+over normal projects. The following is an annotated example build script,
+explaining why each step is necessary and when they can be omitted.
+
+```sh
+# Build and install project (using current CFLAGS, CXXFLAGS). This is required
+# for projects with C extensions so that they're built with the proper flags.
+pip3 install .
+
+# Build fuzzers into $OUT. These could be detected in other ways.
+for fuzzer in $(find $SRC -name '*_fuzzer.py'); do
+  fuzzer_basename=$(basename -s .py $fuzzer)
+  fuzzer_package=${fuzzer_basename}.pkg
+
+  # To avoid issues with Python version conflicts, or changes in environment
+  # over time on the OSS-Fuzz bots, we use pyinstaller to create a standalone
+  # package. Though not necessarily required for reproducing issues, this is
+  # required to keep fuzzers working properly in OSS-Fuzz.
+  pyinstaller --distpath $OUT --onefile --name $fuzzer_package $fuzzer
+
+  # Create execution wrapper. Atheris requires that certain libraries are
+  # preloaded, so this is also done here to ensure compatibility and simplify
+  # test case reproduction. Since this helper script is what OSS-Fuzz will
+  # actually execute, it is also always required.
+  # NOTE: If you are fuzzing python-only code and do not have native C/C++
+  # extensions, then remove the LD_PRELOAD line below as preloading sanitizer
+  # library is not required and can lead to unexpected startup crashes.
+  echo "#!/bin/sh
+# LLVMFuzzerTestOneInput for fuzzer detection.
+this_dir=\$(dirname \"\$0\")
+LD_PRELOAD=\$this_dir/sanitizer_with_fuzzer.so \
+ASAN_OPTIONS=\$ASAN_OPTIONS:symbolize=1:external_symbolizer_path=\$this_dir/llvm-symbolizer:detect_leaks=0 \
+\$this_dir/$fuzzer_package \$@" > $OUT/$fuzzer_basename
+  chmod +x $OUT/$fuzzer_basename
+done
+```
+
+## Hypothesis
+
+Using [Hypothesis](https://hypothesis.readthedocs.io/), the Python library for
+[property-based testing](https://hypothesis.works/articles/what-is-property-based-testing/),
+makes it really easy to generate complex inputs - whether in traditional test suites
+or [by using test functions as fuzz harnesses](https://hypothesis.readthedocs.io/en/latest/details.html#use-with-external-fuzzers).
+
+> Property based testing is the construction of tests such that, when these tests are fuzzed,
+  failures in the test reveal problems with the system under test that could not have been
+  revealed by direct fuzzing of that system.
+
+We recommend using the [`hypothesis write`](https://hypothesis.readthedocs.io/en/latest/ghostwriter.html)
+command to generate a starter fuzz harness.  This "ghostwritten" code may be usable as-is,
+or provide a useful template for writing more specific tests.
+
+See [here for the core "strategies"](https://hypothesis.readthedocs.io/en/latest/data.html),
+for arbitrary data, [here for Numpy + Pandas support](https://hypothesis.readthedocs.io/en/latest/numpy.html),
+or [here for a variety of third-party extensions](https://hypothesis.readthedocs.io/en/latest/strategies.html)
+supporting everything from protobufs, to jsonschemas, to networkx graphs or geojson
+or valid Python source code.
+Hypothesis' integrated test-case reduction also makes it trivial to report a canonical minimal
+example for each distinct failure discovered while fuzzing - just run the test function!
+
+To use Hypothesis in OSS-Fuzz, install it in your Dockerfile with
+
+```shell
+RUN pip3 install hypothesis
+```
+
+See [the `ujson` structured fuzzer](https://github.com/google/oss-fuzz/blob/master/projects/ujson/hypothesis_structured_fuzzer.py)
+for an example "polyglot" which can either be run with `pytest` as a standard test function,
+or run with OSS-Fuzz as a fuzz harness.

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
