In order to serve you well, Testacular needs to know about your project. That's done through a configuration file.
For an example file, see test/client/testacular.conf.js which contains most of the options.
You can write the config file by hand or copy paste it from another project.
A third way is to use testacular init
to generate it.
# This will ask you a few questions and generate a new config file
# called my.conf.js
$ testacular init my.conf.js
When starting testacular, you can pass a path to the configuration file as an argument.
By default, Testacular will look for testacular.conf.js
in the current directory.
# Start Testacular using your configuration
$ testacular start my.conf.js
For more info about configuration file, see the configuration file docs.
Some of the configurations can be specified as a command line argument, which overrides the configuration from the config file.
Try testacular start --help
if you want to see all available options.
