=head1 NAME

test.pl - pgBackRest Unit Tests

=head1 SYNOPSIS

test.pl [options]

 Test Options:
   --module             test module to execute
   --test               execute the specified test in a module
   --run                execute only the specified test run
   --process-max        max processes to run for compression/transfer (default 1)
   --dry-run            show only the tests that would be executed but don't execute them
   --no-cleanup         don't cleaup after the last test is complete - useful for debugging
   --db-version         version of postgres to test (all, defaults to minimal)
   --log-force          force overwrite of current test log files
   --no-lint            disable static source code analysis
   --build-only         compile the C library / packages and run tests only
   --coverage-only      only run coverage tests (as a subset of selected tests)
   --smart              perform libc/package builds only when source timestamps have changed
   --no-package         do not build packages
   --no-ci-config       don't overwrite the current continuous integration config
   --dev                --no-lint --smart --no-package --vm-out --process-max=1

 Configuration Options:
   --psql-bin           path to the psql executables (e.g. /usr/lib/postgresql/9.3/bin/)
   --test-path          path where tests are executed (defaults to ./test)
   --log-level          log level to use for tests (defaults to INFO)
   --quiet, -q          equivalent to --log-level=off

 VM Options:
   --vm                 docker container to build/test (u12, u14, co6, co7)
   --vm-build           build Docker containers
   --vm-force           force a rebuild of Docker containers
   --vm-out             Show VM output (default false)
   --vm-max             max VMs to run in parallel (default 1)

 General Options:
   --version            display version and exit
   --help               display usage and exit
