Remove test_server as a standalone application
The test_server application has previously been deprecated. In OTP 19, we will move relevant parts of test_server into the common_test application. Test suites that include test_server.hrl must be updated to include ct.hrl instead. Test suites that include test_server_line.hrl must removed that inclusion. Test suites that call the test_server module directly will continue to work in OTP 19. The test suites for Erlang/OTP are built and executed in exactly the same way as previously. Here are some more details. The modules test_server*.erl and erl2html2.erl in lib/test_server/src have been moved to common_test/src. The test_server.hrl and test_server_line.hrl include files have been deleted. The macros in test_server.hrl have been copied into lib/common_test/include/ct.hrl. The ts*.erl modules and their associated data files in lib/test_server/src has been been moved to the new directory lib/common_test/test_server. The ts* modules are no longer built to lib/common_test/ebin. They will only built when 'make release_tests' is executed. The test suite for test_server has been moved to lib/common_test/test. The rest of the files have been deleted.
