I am interpreting your question as follows:

Does the test suite test whether an SPF implementation correctly selects a
singular "v=spf1 ..." record in the presence of other, non-"v=spf1" TXT
records?

Answer:

Yes, it does, via the "nospace2" test case, assuming the test suite is
being interpreted correctly.  (The test suite is merely a specification of
scenarios and expected results.  For it to "work" correctly, it depends on
a test suite "driver" feeding the data to an SPF implementation and
checking the results returned.)

A correct test suite driver will find the SPF-type records in the
"nospace2" test's zonedata and synthesize identical TXT-type records from
them (see <http://www.openspf.org/Test_Suite/Schema>).  The "v=spf10"
record (SPF-type or TXT-type) must then be treated as any random non-
"v=spf1" record (just like your "line1" ... "line n" record) by the
implementation and ignored in favor of the other record, which starts
with "v=spf1".

An implementation that croaks on a non-"v=spf1" record even though another
record exists that starts with "v=spf1", will fail the test suite,
provided the test suite driver works correctly.
