    This is the raw JSON adapter for unexpected-htmllike

    If expects and creates objects with type, props and children keys.

    type is the element type name

    props is an object with key-value of the properties of the element

    children is always an array (even for a single child or no children) of the sub-elements, also objects in the same format.


    You need to instantiate a new instance of the adapter in order to use it. With the instance, you can set options (using setOptions({ ... })) to influence how certain things are returned to unexpected-htmllike.

    var UnexpectedHtmlLike = require('unexpected-htmllike');
    var RawAdapter = require('unexpected-htmllike-raw-adapter');
    var adapter = new RawAdapter();
    var rawHtmlLike = new UnexpectedHtmlLike(adapter);
    // Now you can use rawHtmlLike.diff(...) etc



    Available options:

    • concatTextContent - (default false) set this to true, to concatenate text content items.
    • convertToString - (default false) converts the content to strings. This is useful when comparing against a rendered result, where only strings are available, but you want to maintain the separate items
    • convertMultipleRawToStrings - (default: false) - converts content to strings, when there is more than one content item. This is done specifically for comparing with rendered react elements, where the type is the original for single children, but is already converted to a string when there are multiple raw siblings

    For example, with the following JSX, when rendered with the react-test-renderer

      Button was clicked {this.state.clickCount} times

    The <button> will have 3 content items:

    (Let's say this.state.clickCount === 10)

    [ 'Button was clicked ', 10, ' times' ]

    If you're diffing with unexpected-htmllike, these 3 content items must match exactly. When setting concatTextContent to true, this would result in a single string content item

    [ 'Button was clicked 10 times' ]

    If the convertToString option is true, the following is returned

    [ 'Button was clicked ', '10', ' times' ]

    The options take immediate effect, and can be changed per instance of the adapter (hence, you could, although not recommended), set the options differently for the actualAdapter and the expectedAdapter for unexpected-htmllike
