For no obvious reason, isolationtester has always insisted that session and step names be written with double quotes. This is fairly tedious and does little for test readability, especially since the names that people actually choose almost always look like normal identifiers. Hence, let's tweak the lexer to allow SQL-like identifiers not only double-quoted strings. (They're SQL-like, not exactly SQL, because I didn't add any case-folding logic. Also there's no provision for U&"..." names, not that anyone's likely to care.) There is one incompatibility introduced by this change: if you write "foo""bar" with no space, that used to be taken as two identifiers, but now it's just one identifier with an embedded quote mark. I converted all the src/test/isolation/ specfiles to remove unnecessary double quotes, but stopped there because my eyes were glazing over already. Like 741d7f104, back-patch to all supported branches, so that this isn't a stumbling block for back-patching isolation test changes. Discussion: https://postgr.es/m/759113.1623861959@sss.pgh.pa.us
PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check". Check src/test/Makefile to see which tests get run automatically. authentication/ Tests for authentication (but see also below) examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level kerberos/ Tests for Kerberos/GSSAPI authentication and encryption ldap/ Tests for LDAP-based authentication locale/ Sanity checks for locale data, encodings, etc mb/ Tests for multibyte encoding (UTF-8) support modules/ Extensions used only or mainly for test purposes, generally not suitable for installing in production databases perl/ Infrastructure for Perl-based TAP tests recovery/ Test suite for recovery and replication regress/ PostgreSQL's main regression test suite, pg_regress ssl/ Tests to exercise and verify SSL certificate handling subscription/ Tests for logical replication
