Problem: the system test 'is()' checker was poorly thought out. For example, there is no way to check for inequality or for absence of a substring. Solution, step 1: introduce new assert(), copied almost verbatim from buildah, where it has been successful in addressing the gaps in is(). The logical next step is to search the tests for 'die' and for 'run', looking for negative assertions which we can replace with assert(). There were a lot, and in the process I found a number of ugly bugs in the tests themselves. I've taken the liberty of fixing these. Important note: at this time we have both assert() and is(). Replacing all instances of is() would be impossible to review. Signed-off-by: Ed Santiago <santiago@redhat.com>
