Capter CLI

Run your tests anywhere

The Capter CLI works great both locally and in CI – and it runs on Linux, OSX and Windows.

npm install capter --save-dev

Create a test

Adding tests is incredibly fast. Create your own to get started, or run the command below:

$ capter init
name: users
- name: create user
url: POST ${{ env.URL }}
- !expect status to_equal 201
- !expect to_equal

Run the CLI

Once you have a test, all you have to do is run the CLI and it will find and run it:

$ capter test

Compose advanced requests

Create advanced API request flows using previous payloads and external data.

Composing requests

name: users
- name: create user
id: user
url: POST ${{ env.URL }}

- name: delete user
url: DELETE ${{ env.URL }}
id: ${{ }}
- !expect status to_equal 204

But wait... There's more!
