The LexicalPath instance methods dirname(), basename(), title() and
extension() will be changed to return StringView const& in a further
commit. Due to this, users creating temporary LexicalPath objects just
to call one of those getters will recieve a StringView const& pointing
to a possible freed buffer.
To avoid this, static methods for those APIs have been added, which will
return a String by value to avoid those problems. All cases where
temporary LexicalPath objects have been used as described above haven
been changed to use the static APIs.
Split out the functionality to gather multiple tests from the filesystem
and run them in turn into Test::TestRunner, and leave the JavaScript
specific test harness logic in Test::JS::TestRunner and friends.
This will not show the colorful human-readable file results and final
test results summary but instead output a JSON blob containing all test
information, which can then be processed by other programs easily.
