I have been using cakephp for a while, and I have made some updates to
the cakephp testing and code coverage framework which I would like to
submit for review. If there is a better way to achieve this, or this
already exists in cakephp, I would be grateful if someone can send me
pointers.
Changes included in the patch
- Add test hook functions to email sending, Session flash display and
page redirection to enable asserting these operations in the test
suite.
- Remove caching of DB schema during test suite execution. Without
this test suite fails when there are many models & controllers that
use different fixtures
- Enhancements to allow code coverage when executing group test cases,
specifically ALL
test cases, and provide a clickable file list for code coverage
summary.
- Enable code coverage tracking only while running the actual test
cases, instead of all code.
Reason: Much quicker execution test suite execution with coverage.
Also is there a good way of checking is the test suite is running as
opposed to real code? I have noticed in different places where they
check the url for the pattern 'test.php', which might fail if this
pattern is part of the url.
I am using a define called 'TEST_SUITE' which I am setting at the
start of the test suite execution, but there should be a better way of
doing this.
The patch follows below.
Cheers,
