ct_run
Description
The ct_run program is automatically installed with Erlang/OTP and the Common Test application (for more information, see section Installation in the User's Guide). The program accepts different start flags. Some flags trigger ct_run to start Common Test and pass on data to it. Some flags start an Erlang node prepared for running Common Test in a particular mode.
The interface function ct:run_test/1, corresponding to the ct_run program, is used for starting Common Test from the Erlang shell (or an Erlang program). For details, see the ct manual page.
ct_run also accepts Erlang emulator flags. These are used when ct_run calls erl to start the Erlang node (this makes it possible to add directories to the code server path, change the cookie on the node, start more applications, and so on).
With the optional flag -erl_args, options on the ct_run command line can be divided into two groups:
- One group that Common Test is to process (those preceding -erl_args).
- One group that Common Test is to ignore and pass on directly to the emulator (those following -erl_args).
Options preceding -erl_args that Common Test does not recognize are also passed on to the emulator untouched. By -erl_args the user can specify flags with the same name, but with different destinations, on the ct_run command line.
If flags -pa or -pz are specified in the Common Test group of options (preceding -erl_args), relative directories are converted to absolute and reinserted into the code path by Common Test. This is to avoid problems loading user modules when Common Test changes working directory during test runs. However, Common Test ignores flags -pa and -pz following -erl_args on the command line. These directories are added to the code path normally (that is, on specified form).
Exit status is set before the program ends. Value 0 indicates a successful test result, 1 indicates one or more failed or auto-skipped test cases, and 2 indicates test execution failure.
If ct_run is called with option -help, it prints all valid start flags to stdout.
