Passing Params to DSS 1) Test parameters are 'imported' automatically into the javascript to be executed. In particular, the following parameters are 'imported': Software assets parameters (i.e. parameters defined in Testlink's build description) DUT provisioning parameters (i.e. parameters defined in Testslink's test case as 'DUT parameters') Application control parameters (i.e. parameters defined in Testslink's test case as 'Application parameters') 2) The parameters are available in javascript via autotestEnv map. For example to access the outFile value use 'autotestEnv.outFile' in your javascript 3) The default behavior described above can be overridden in your test script by setting the equipment's 'target.ccs.jsEnvArgsFile' variable.
