Abstract: Systems and methods are provided for facilitating software testing. Test data available for testing computer program testing is stored at a data store. An individual may submit a reservation request for a portion of the test data. A reservation device may reserve the selected portion of the test data such that, while it is reserved, the test data is only modifiable during tests initiated by the individual that reserved it. Other individuals may be restricted from modifying test data they have not reserved. A test data search interface may be used to configure a search query for the test data. An estimated reservation duration may be received with a reservation request, and notifications may be provided when that duration has or is about to expire. The reserved test data may be released for subsequent reservation, or the reservation may be renewed upon receipt of a renewal request.
