This page defines what our current approach versus our BluePrint for future options

Test-Driven Development is a programming style which says that you 1st write your test cases (from the specs) & then proceed to make them pass.

Automated Tests

Unit Tests

There are additional unit tests available, which also require running with the IFRC_Train preopulate, 'settings.base.prepopulate = 27':

To run all unit tests:

python web2py.py -S eden -M -R applications/eden/modules/unit_tests/suite.py

These unit tests are meant to detect problems early during development, which means you should run them quite often while you're still working on the code (read: before and after every little change you make) rather than expecting them to be run during QA cycles. That again means you would more often need to run tests for particular modules than the whole suite.

For every module in modules/s3 and modules/eden, you can find the corresponding unit test module under modules/unit_tests/eden resp. modules/unit_tests/s3 (if one exists).

To run tests for particular modules:

# e.g. for modules in modules/s3
python web2py.py -S eden -M -R applications/eden/modules/unit_tests/s3/s3resource.py
# e.g. for modules in modules/eden
python web2py.py -S eden -M -R applications/eden/modules/unit_tests/eden/pr.py

It can be a very powerful development strategy - especially for back-end APIs - to first implement unit test cases for the functionality you intend to implement before actually implementing it. Apart from preventing bugs, this helps you to validate your design against requirements, and to keep the implementation simple and focussed. Additionally, the test cases can be a rich source of code samples how to apply your API methods.

Smoke Tests

python web2py.py -S eden -M -R applications/eden/modules/tests/suite.py -A --suite smoke --force-debug --link-depth 16 -V 3

Selenium Tests

python web2py.py -S eden -M -R applications/eden/modules/tests/suite.py

See: wiki:QA/Automated/Selenium for more details

Role Tests

This test is used to check the permissions of user roles. Currently is limited to the IFRC (Red Cross) roles for RMS, but could be extended:

python web2py.py -S eden -M -R applications/eden/modules/tests/suite.py -A --suite roles

Benchmark Tests

The Benchmark Tests are a simple way of measuring the performance

python web2py.py -S eden -M -R applications/eden/modules/unit_tests/s3/benchmark.py

Load Tests

Load Testing will measure the performance of the entire Sahana Eden stack. We recommend using Tsung. See: Testing/Load for more details

Continuous Integration (CI)Server

See: SysAdmin/ContinuousIntegration for how we have set up the CI Server and help to find the exact commands to run the tests.

Test Cases
