Running your experiment

Search…

Once you have created an experiment using either create-empirica-app or a git clone.

Running the app locally
Run the app on your local machine with one command:
empirica
This can take a few minutes.
This will start the app that you can access as a participant: http://localhost:3000​
You can access the admin panel here: http://localhost:3000/admin/​
Log in with the username and password found in .empirica/empirica.toml.
Loading the factors and treatments
Treatments and factors can also be entered manually via the admin panel.
Empirica also enables "experiment as code" by which experimental treatments and factors can edited directly in YAML at .empirica/treatments.yaml. 
Testing the app
To run a game, create a new batch with the games of treatments you want to use and click start on the batch.
Open a player tab by going to http://localhost:3000.
The player that you open with http://localhost:3000 is cached on your browser. Whenever you start a game with this player, your local app will keep that information. To play again there are multiple things you can do:
Click on the Reset current session button in the bottom right menu to reset this player, and create a new game for this player to join.
Click on the New Player button in the bottom right menu to open a new tab with a different player (you will see tab with an id).
The app will automatically ("hot") reload when save changes to the code.
