JSON Patch Tests

These are test cases for implementations of IETF JSON Patch (RFC6902).

Some implementations can be found at jsonpatch.com.

Test Format

Each test file is a JSON document that contains an array of test records. A test record is an object with the following members:

doc: The JSON document to test against
patch: The patch(es) to apply
expected: The expected resulting document, OR
error: A string describing an expected error
comment: A string describing the test
disabled: True if the test should be skipped

All fields except 'doc' and 'patch' are optional. Test records consisting only of a comment are also OK.

Files

tests.json: the main test file
spec_tests.json: tests from the RFC6902 spec

Writing Tests

All tests should have a descriptive comment. Tests should be as simple as possible - just what's required to test a specific piece of behavior. If you want to test interacting behaviors, create tests for each behavior as well as the interaction.

If an 'error' member is specified, the error text should describe the error the implementation should raise - not what's being tested. Implementation error strings will vary, but the suggested error should be easily matched to the implementation error string. Try to avoid creating error tests that might pass because an incorrect error was reported.

Please feel free to contribute!
