QuickStart

Add the following to your project's pom.xml:

<dependency>

<groupId>org.skyscreamer</groupId>

<artifactId>jsonassert</artifactId>

<version>0.9.0</version>

</dependency>

And use JSONAssert.assertEquals just like you'd used Assert.assertEquals in existing JUnit test cases. That's it.

Behind the scenes, JSONAssert, converts your "expected" string to a JSON object, and compares that to the result you want to test. It performs a logical comparison -- much like the don't-do-this example above, but a lot cleaner. On test failure, the result messages are very specific and should simplify troubleshooting.
