Environment variables

Using environment variables is a powerful way of running the same tests in different environments.

.env file#

You can add environment variables in your .env file, and Capter will automatically read it.

# testing locally
# testing prod


You can also run the CLI with the environment variables inline in the command:

URL=http://localhost:3000 capter test

Using the variables#

To use the environment variable, you can use the template tag syntax and the env context:

# .capter/products.yml
name: products
- name: fetch all products
# grab the base URL from an environment variable
url: ${{ env.URL }}/api/products
- !expect status to_equal 200
- !expect body to_be_array

Variables in CI#

When you run the CLI in a CI environment, all environment variables provided by that CI will be available in the env scope. For example, if you use GitHub Actions, this is what you can do.
