phantomcss-kit v0.2.5

phantomcss-kit

This NPM utility library provides a quick way to run a pre-defined PhantomCSS test suite against your web page.

Requirements

• Python is required to run CasperJS.

Usage

1. Install:

npm i phantomcss-kit --save-dev

2. Create a page you would like run the tests against. Mark the elements to test using the pk-test attribute:

<div pk-test="first">Hello!</div>

The value of pk-test will be used as the name of the test case.

3. Run the tests:

pk-test --url=%ABSOLUTE_PAGE_URL%

Generating test cases

To generate new test cases, use the --rebase flag:

pk-test --url=%ABSOLUTE_PAGE_URL% --rebase

Running a local web server

If you don't have a local web server at hand, you can start one together with the test suite:

pk-test --url=%ABSOLUTE_PAGE_URL% --serveDir=%PATH_TO_TEST_FOLDER%

You can set a custom port using the optional --port argument.

Configuring a delay

In case you are unable to take a screenshot of some element because it hasn't loaded yet, you can configure a fixed delay before taking screenshots:

pk-test --url=%ABSOLUTE_PAGE_URL% --wait=3000

Tolerance

The tolerance level can be adjusting using the --tolerance argument:

pk-test --url=%ABSOLUTE_PAGE_URL% --tolerance=1.25
