We're in the process of converting the existing testsuite machinery to
|
|
use the new style DejaGnu framework. Eventually, we'll abandon
|
|
../mkcheck.in in favor of this new testsuite framework.
|
|
|
|
Basically, a testcase contains dg-keywords (see dg.exp) indicating
|
|
what to do and what kinds of behaviour are to be expected. New
|
|
testcases should be written with the new style DejaGnu framework in mind.
|
|
|
|
The V3 testing framework supports additional keywords for the purpose
|
|
of easing the job of writing testcases. All V3-keywords are of the
|
|
form @xxx@. Currently supported keywords include:
|
|
|
|
@require@ <files>
|
|
The existence of <files> is essential for the test to complete
|
|
successfully. For example, a testcase foo.C using bar.baz as
|
|
input file could say
|
|
// @require@ bar.baz
|
|
The special variable % stands for the rootname, e.g. the
|
|
file-name without its `.C' extension. Example of use (taken
|
|
verbatim from 27_io/filebuf.cc)
|
|
// @require@ %-*.tst %-*.txt
|
|
|
|
@diff@ <first-list> <second-list>
|
|
After the testcase compiles and ran successfully, diff
|
|
<first-list> against <second-list>, these lists should have the
|
|
same length. The test fails if diff returns non-zero a pair of
|
|
files.
