Common Test

To run common_test suites:

$ rebar3 ct 

Rebar3 will look in all your applications’ test directories and compile and run any source files named *_SUITE.erl. Unlike regular source directories, the compilation of test modules will not be recursive by default in order to avoid issues with files in data directories. This behaviour can however be turned on manually with the right compilation options.

To run only specific test suites:

$ rebar3 ct --suite=test/first_SUITE,test/second_SUITE 

Rebar3 has a built in common_test runner that supports most test suites and common_test options. If your test suites require use of test specs or cover specs be aware Rebar3 keeps separate build artifacts for each profile so you may need to adjust paths to point to the modules and directories in the relevant profile directory under _build for them to work as expected. If you need to use an unsupported common_test option the following command can be used to run common_test with the path to the compiled beam files Rebar3 generates

$ ct_run -pa `rebar3 path` ... 

The ct command runs as the test profile by default. See Profiles for details.

For available options and their usage see Commands or:

$ rebar3 help ct
