# JSON-Java-unit-test

Unit tests to validate the JSON-Java GitHub project code<br>
https://github.com/douglascrockford/JSON-java<br>

*These tests are a work in progress. Help from interested developers is welcome.*<br>
More coverage is needed, but more importantly, improvements to test quality is needed.<br>

Test harness: http://junit.org<br>
Coverage: http://www.eclemma.org/<br>

Eclipse is the recommended development environment.
Run individual tests or <b>JunitTestSuite</b> using *EclEmma Coverage*, or execute the <b>TestRunner<b> application directly.<br>

Test filenames should consist of the name of the module being tested, with the suffix "Test". 
For example, <b>Cookie.java</b> is tested by <b>CookieTest.java</b>.
When adding a new unit test, don't forget to update <b>JunitTestSuite.java</b>.

The fundamental issues with JSON-Java testing are:
* <b>JSONObjects</b> are unordered, making simple string comparison ineffective. 
* Comparisons via **equals()** is not currently supported. Neither <b>JSONArray</b> nor <b>JSONObject</b> overrride <b>hashCode()</b> or <b>equals()</b>, so comparison defaults to the <b>Object</b> equals(), which is not useful.
* Access to the <b>JSONArray</b> and <b>JSONObject</b> internal containers for comparison is not currently available.
* <b>JSONObject</b> sometimes wraps entries in quotes, other times does not, complicating comparisons.

When you start working on a test, add the empty file to the repository and update the readme, so that others will know that test is taken.

A unit test has the following stages:

|No test|
|In progress|
|Coverage > 90%|
|Reasonable test cases|
|Checked against previous unit tests|
