With a negative number Predis will count from the end of the arguments list
to calculate the actual number of keys that will be interpreted as elements
for `KEYS` by the underlying `EVAL` command.
Fix also a few bugs found while rewriting the test suite.
In order to be able to run integration tests, the test suite requires
a version of Redis >= 2.4.0.
The units have been splitted into several different groups using
PHPUnit @group annotation to allow developers to enable, disable
and combine certain types of tests. The available groups are:
- disconnected: can run without a Redis server online
- connected: active connection to a Redis server is required
- commands: test dedicated to a specific Redis command
- slow: performs operations that can slow down execution;
A list of the available groups can be obtained by running
phpunit --list-groups
Groups of tests can be disabled or enabled via the XML configuration
file or the standard command-line test runner. Please note that due
to a bug in PHPUnit, older versions ignore the --group option when
the group is excluded in the XML configuration file. Please refer to
http://github.com/sebastianbergmann/phpunit/issues/320 for details
Integration tests in the @connected group check if the command being
tested is defined in the selected server profile (see the value of
the TEST_SERVER_VERSION constant in phpunit.xml). If the command is
not defined in the target server profile, the integration test is
automatically marked as skipped.
We also provide an helper script in the bin directory that can be
used to automatically generate a file with the scheleton of a test
case for a Redis command by specifying the name of the class in the
Predis\Commands namespace. For example, to generate a test case for
SET (represented by the Predis\Commands\StringSet class):
./bin/generate-command-test.php --class=StringSet
The realm of a command is automatically inferred from the name of the
class, but it can be set using the --realm option.
