pg_probackup/tests

****see wiki

Note: For now these tests work on Linux and "kinda" work on Windows

Note: tests require python3 to work properly.

Windows Note: For tablespaces tests to work on Windows, you should explicitly(!) grant current user full access to tmp_dirs

Check physical correctness of restored instances:
 Apply this patch to disable HINT BITS: https://gist.github.com/gsmol/2bb34fd3ba31984369a72cc1c27a36b6
 export PG_PROBACKUP_PARANOIA=ON

Check archive compression:
 export ARCHIVE_COMPRESSION=ON

Enable compatibility tests:
 export PGPROBACKUPBIN_OLD=/path/to/previous_version_pg_probackup_binary

Specify path to pg_probackup binary file. By default tests use <Path to Git repository>/pg_probackup/
 export PGPROBACKUPBIN=<path to pg_probackup>

Remote backup depends on key authentication to local machine via ssh as current user.
 export PGPROBACKUP_SSH_REMOTE=ON

Run tests that are relied on advanced debugging features. For this mode, pg_probackup should be compiled without optimizations. For example:
CFLAGS="-O0" ./configure --prefix=/path/to/prefix --enable-debug --enable-cassert --enable-depend --enable-tap-tests --enable-nls

 export PGPROBACKUP_GDB=ON

Run suit of basic simple tests:
 export PG_PROBACKUP_TEST_BASIC=ON

Run ptrack tests:
 export PG_PROBACKUP_PTRACK=ON

Run long (time consuming) tests:
 export PG_PROBACKUP_LONG=ON

Usage:
 sudo echo 0 > /proc/sys/kernel/yama/ptrace_scope
 pip install testgres
 export PG_CONFIG=/path/to/pg_config
 python -m unittest [-v] tests[.specific_module][.class.test]
