WAchecker is designed with its extensibility in mind. Additional tests can be generally added without any modifications to WAchecker. WAchecker is also written in a popular scripting language Python to make it accessible to many programmers.
People interested in Web accessibility are encouraged to improve existing tests and write new ones. If you do so, please share the results with other WAchecker users to help improving overall Web accessibility, see Contact Information.
This section is just a brief guideline to writing and improving test. Refer to test source code for examples and additional information.
