Squash TA (Test Automation) is an open source tool for automating functional tests and industrialization of their executions. Compatible with several open source PLCs (Ex. Selenium), it allows management of the automated tests of web applications, web services and batches. The features of Squash TA are based on developments initiated in 2009 by Henix. Realized to meet the automation needs of the TRA (Third Party Recipe Applicative) of this SSII, these developments were donated to the community Squash to constitute the base of Squash TA.
