The weekly promoted builds of GlassFish vary in stability but have passed a minimum level of testing, which includes the quicklook tests, a sub-set of CTS tests (representative collection of 263 J2EE 1.4 tests) and a sub-set of SQE tests (22 in number). A build is not promoted unless it passes quicklook, CTS smoke and SQE smoke tests.
