For example, in many circumstances, +[\fBconfigure\fR] will be automatically called shortly after +[\fBpackage require tcltest 2.1\fR] succeeds with arguments +from the variable \fB::argv\fR. This is to support test suites +that depend on the old behavior that \fBtcltest\fR was automatically +configured from command line arguments. New test files should not +depend on this, but should explicitly include .CS -test testOnUnixWithoutThreads-1.1 { - this test runs only on unix and only if we're not testing - threads -} { - -constraints {unixOnly && !testthread} - -body { - # some script goes here - } -} +eval tcltest::configure $::argv .CE - +to establish a configuration from command line arguments. .SH "KNOWN ISSUES" There are two known issues related to nested evaluations of [\fBtest\fR]. The first issue relates to the stack level in which test scripts are |
