Testmode

Alter existing site content and other configurations when running tests.

This is a module to support testing, so it is not expected to be used in
production (although, it adheres to Drupal coding standards and has good test
coverage).

Development of this module takes place on GitHub: https://github.com/AlexSkrypnyk/testmode

Use case

Running a Behat test on the site with existing content may result in
false positives because of the live content being mixed with test content.

Example: a list of 3 featured articles. When the test creates 3 articles and make
them featured, there may be existing featured articles that will confuse tests
resulting in false positive failure.

How it works

1. When writing Behat tests, all test content items (nodes,
terms, users) follow specific pattern. For example, node titles start with
[TEST] .
2. A machine name of a view, which needs to be tested, is added to
Testmate configuration form.
3. Behat test tagged with @testmode will put
the site in test mode that will filter-out all items in the view that do not
fit the pattern, leaving only content items created by the test.
