CasperJS-as-a-Service

CasperJS is a navigation scripting and testing utility for PhantomJS and SlimerJS written in JavaScript. CasperJS-as-a-Service makes CasperJS available as a web service. Dockerfile included.

How to run CasperJS-as-a-Service in Docker?

The following command makes CasperJS-as-a-Service available at 127.0.0.1:31337:

export HOSTPORT=31337
docker run -d --name casperjs -p 127.0.0.1:$HOSTPORT:80 metmajer/casperjs-as-a-service

How to issue a CasperJS script job?

CasperJS-as-a-service makes a /job endpoint available, which serves requests via HTTP POST:

curl -f -H "Content-Type: application/json" http://127.0.0.1:$HOSTPORT/job -d '{
    "git": {
      "uri": "https://github.com/casperjs/casperjs.git",
      "contextDir": "samples"
    },
    "casper": {
      "script": "dynamic.js"
    }
  }'

How to issue a CasperJS test job?

CasperJS-as-a-service makes a /job endpoint available, which serves requests via HTTP POST:

curl -f -H "Content-Type: application/json" http://127.0.0.1:$HOSTPORT/job -d '{
    "git": {
     "uri": "https://github.com/casperjs/casperjs.git",
      "contextDir": "samples"
    },
    "casper": {
      "mode": "test",
      "script": "googletesting.js"
    }
  }'

You can advise CasperJS-as-a-Service to run all tests inside git.contextDir when casper.mode is set to test and casper.script is left undefined.

curl -f -H "Content-Type: application/json" http://127.0.0.1:$HOSTPORT/job -d '{ \
    "git": {
      "uri": "https://github.com/casperjs/casperjs.git",
      "contextDir": "samples"
    },
    "casper": {
      "mode": "test"
    }
  }'

Note that this will only work with directories that do not contain navigation scripts (with CasperJS, navigation scripts and tests service a different purpose and have to be invoked in different ways). In the above example, casperjs will fail with the following error:

Test file: /tmp/92e6b4e3-4eb2-4838-a13d-a2f6c1b6b73c/samples/bbcshots.js
FAIL Fatal: you can't override the preconfigured casper instance in a test environment.
#    type: error
#    file: /tmp/92e6b4e3-4eb2-4838-a13d-a2f6c1b6b73c/samples/bbcshots.js
#    subject: false
#    error: "Fatal: you can't override the preconfigured casper instance in a test environment."
#    stack: in create() in phantomjs://platform/casper.js:54
