# Guava Testlib: Google Testing Libraries for Java

Guava testlib is a set of Java classes for more convenient
unit testing.

## Adding Guava Testlib to your build

Guava testlib's Maven group ID is `com.google.guava` and its artifact ID is `guava-testlib`.

To add a dependency on Guava testlib using Maven, use the following:

```xml
<dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava-testlib</artifactId>

    private final transient ClassSanityTester tester;

    SerializableDummyProxy(ClassSanityTester tester) {
      this.tester = tester;
    }

    @Override
    <R> R dummyReturnValue(TypeToken<R> returnType) {
      return tester.getDummyValue(returnType);
    }

    @Override
    public boolean equals(@Nullable Object obj) {

# We run this separately so that its change to the default toolchain doesn't affect anything else.
