Karma-html NPM

Description

Use karma-html to test your html files in the browser with karma

karma-html loads the chosen .html files into the iframe elements in the context.html karma browser runner.
karma-html allows you to open, refresh, close and set the dimensions of the iframes through your test suits whenever you want.
karma-html gives you the access to the Document object of each loaded .html file through your test suits. Testing .html files via its Document objects seems much more genuine and reliable than when HTML content is appended into the div containers.

See also karma-jasmine-dom [npm] (Set of 19 jasmine custom matchers configured for karma to test html DOM)

Ok, I've already tested my .html files, I don't need it anymore, I want to close them. [see below]
I've got million .html files to test! I'd prefer to open, test and close each .html file separately, rather than open them all at once! [see below]
How do I know, if the .html file has been loaded successfully and whether it is ready to be tested? [see below]
The .html files are loading for ages! Perhaps something's not right... I want to set timeout! [see below]
I want to test the responsiveness of the layout. [see below]

Config

use npm install karma-html --save-dev
Add "karmaHTML" as a reporter in the karma config file
Add karmaHTML object in the client object in the karma config file

module.exports = function(config) {
  config.set({ 
    //other karma settings
    reporters: ["karmaHTML"],
    client: {
      karmaHTML: {
        //all karma-html settings
      }
    }
  });
};

client.karmaHTML properties

All config properties (excluding client.karmaHTML.source) are optional. For the omitted properties, the properties of the incorrect type or value, the default values will be used instead.

client.karmaHTML.`source`

Type: Array
Default: If the source property is of the incorrect syntax or does not indicate any (or existing) .html file, the suitable hint errors will occure with the clear explanation what to fix. The karma will run without karma-html module if the client.karmaHTML.source property is incorrect anyway.
Description: Indicates the .html file(s) that should be loaded into the iframes. The array should include object-type items with src property, that indicates the .html file path and the tag property, that can further be used in the unit tests to get the control of the particular .html file. The tag names should respect JavaScript identifiers constructing rules: [A-Za-z0-9_$], began with letter, _ or $

You do not have to load .html files in the karma config file files array, if you've already loaded them in the client.karmaHTML.source array.
Remember, to load all resources files of you .html files in the karma config file files array.

Syntax example

module.exports = function(config) {
  config.set({
    files: [
      //no need to load your index.html and template.html here
      //all resources of your .html files should be loaded here
	  {pattern: './public/*.js', watched:true, served:true, included:true},
	  {pattern: './public/*.png', watched:false, served:true, included:false},
	  {pattern: './public/fonts/*', watched:false, served:true, included:false}
    ],
    client: {
      karmaHTML:{
        source: [
          {src:'./public/index.html', tag:'index'},
          {src:'./public/template.html', tag:'tmpl'}
        ]
      }
    }
  });
};

client.karmaHTML.`auto`

Type: Boolean
Default: false
Description: If true, the .html files are loaded into the iframes automatically (immediately after the context.html karma browser runner is loaded). If false, the .html files can be loaded manually by invoke open() method [see below].

client.karmaHTML.`timeout`

Type: Number
Default: 0 (no timeout)
Description: The number of milliseconds the iframe server request can take before automatically being terminated. When a timeout happens, the onstatechange method [see below] fires and returns false.

client.karmaHTML.`abort`

Type: Number
Default: 0 (no abort)
Description: The number of milliseconds the loading resources can take before automatically being terminated. When an abort happens, the onstatechange method [see below] fires and returns false.

client.karmaHTML.`width`

Type: String
Default: "90%"
Description: The CSS width of the iframe, that the .html file is about to be loaded into. The value (eg. 600px) is appended to the iframe element as the attribute style="width:600px". Each valid CSS values and units are allowed. Incorrect values will be ignored and the default value will be used instead.

client.karmaHTML.`height`

Type: String
Default: "80vh"
Description: The CSS height of the iframe, that the .html file is about to be loaded into. The value (eg. 600px) is appended to the iframe element as the attribute style="height:600px". Each valid CSS values and units are allowed. Incorrect values will be ignored and the default value will be used instead.

Syntax of `client.karmaHTML` configuration example

module.exports = function(config) {
  config.set({
    //all the karma config here
    client: {
      //all the client config here
      karmaHTML:{
        source: [
          {src:'./public/index.html', tag:'index'},
          {src:'./public/template.html', tag:'tmpl'}
        ],
        auto: true,
        timeout: 10000,
        abort: 60000,
        width: "730px",
        height: "30vw"        
      }
    }
  });
};

`karmaHTML` and `Tag` objects

`window.karmaHTML` | `karmaHTML`

When you configured your karma config file, you have got the access to the karmaHTML object with all features (methods and properties) to control your .html files. The karmaHTML object is created and appended to the window object when the context.html karma browser runner is opened via cmd karma start command.

object structure

KarmaHTML {
  0: Tag
  1: Tag
  index: Tag
  tmpl: Tag
  length: 2
  onstatechange: function() | undefined
  __proto__: {
    open: function()
    close: function()
    reload: function()
    height: (get|set) function()
    width: (get|set) function()
    elementList: {}
    tagList: []
    config: {}
  }
}

`karmaHTML.tagName` | `karmaHTML[Number]`

karmaHTML object lets you controll all .html files, while Tag objects let you control each .html file separately.
Tag objects are generated automatically.
The number of accessible Tag objects is equal to the number of .html files defined in the karma config file.
The Tag objects are accessible via karmaHTML object.
Assuming, that you want to test index.html file of the index tag and the template.html file of the tmpl tag [as above], you would get the two Tag objects with: karmaHTML.index or karmaHTML[0] and karmaHTML.tmpl or karmaHTML[1]

object structure

Tag {
  tag: String
  itemNum: Number
  document: HTMLDocument | null
  iframe: HTMLIFrameElement | null
  src: String
  hasIframe: Boolean
  ready: Boolean
  onstatechange: function() | undefined
  __proto__: {
    _root: karmaHTML
    open: function()
    close: function()
    reload: function()
    height: (get|set) function()
    width: (get|set) function()
  }
}

iframe `Document` object access

How to get the browser access to the Document Object of each .html file loaded into the iframes? Assuming, that you want to test index.html file of the index tag and the template.html file of the tmpl tag [as above]:

You can get the access via the `karmaHTML` object

To get the access to any iframe Document object of loaded .html file, use karmaHTML['tag_name'].document

To get the access to the Document object of index.html file, use karmaHTML.index.document
To get the access to the Document object of template.html file, use karmaHTML.tmpl.document

It gives you the access to the Document object if its iframe is appended to the DOM. Use the open() method or configure the karma config file setting appropriately: client.karmaHTML.auto:true [as above]

You can get the access via the window Object

Each iframe Document object's reference is added to the window object as document_0, document_1, document_2, etc. property. The document_Xs are numbered according to the order of client.karmaHTML.source items (started from 0)

To get the access to the Document object of index.html file, use window.document_0 (or just document_0)
To get the access to the Document object of template.html file, use window.document_1 (or just document_1)
etc.

It gives you the access to the Document object if its iframe is appended to the DOM. Use the open() method or configure the karma config file setting appropriately: client.karmaHTML.auto:true

Methods

The methods can be used: 1. As global methods; eg. karmaHTML.open()
Then it affects all iframes of all .html files (all files are opened at once) 2. As tag methods; eg. karmaHTML.index.open()
Then it affects only the iframe of the .html file of index tag (the index.html is opened only)

`open()`

Syntax: karmaHTML.open() | karmaHTML.tagName.open()
Description: Appends the iframe element into the DOM and loads the .html file.

The karmaHTML.open() opens all .html files defined in the karma config file. If some of the .html files are already opened, the open() method opens only those of the .html files, that are not yet appended to the DOM.
The karmaHTML.index.open() does the same only with the .html file of the index tag. If the particular .html file is already opened, the open() method is ignored.

Parameters: karmaHTML.open(dimensions)

parameter	Syntax	Description
`dimensions`	`{width:String,height:String}`	It sets the CSS width and height properties of the iframe(s). The width and height property are the equivalents of the `karmaHTML.width` and `karmaHTML.height` properties. If the iframe is already opened, only its dimensions will be changed.

example

karmaHTML.open({width:'700px',height:'10%'});   //appends the iframes for all html files with specified dimensions
karmaHTML.index.open({height:'auto'});   //appends only html file of the tag index with specified height dimension
karmaHTML.tmpl.open({width:null,height:null}); //appends html file of tmpl tag with default width and height

`close()`

Syntax: karmaHTML.close() | karmaHTML.tagName.close()
Description: Removes iframe from the document.

The karmaHTML.close() closes (if opened) all iframes of all .html files defined in the karma config file.
The karmaHTML.tmpl.close() does the same only with the .html file of the tmpl tag. If the particular .html file is already closed, the close() method is ignored.

`reload()`

Syntax: karmaHTML.reload() | karmaHTML.tagName.reload()
Description: Refreshes the Document of .html file(s) in the iframes.

The karmaHTML.reload() refreshes all opened iframe Documents.
The karmaHTML.index.reload() refreshes the Document of the .html file of the index tag. If the iframe is not opened, it opens it and loads the .html file instead.

Properties

karmaHTML properties:

`width`

(getter) Syntax: karmaHTML.width
Return value type: Object
(setter) Syntax: karmaHTML.width = String
Description: Sets or returns the width dimension of the iframes of all .html files defined in the karma config file.

`karmaHTML.width = String`

Sets the CSS width of all iframes, eg. karmaHTML.width = '50%'
You can set the width regardless all iframes are appended to the DOM
When used before karmaHTML.open(), the iframes will be opened with the new width value
The value (eg. '600px') is appended to the iframe elements as the attribute style="width:600px"
All valid CSS values and units are allowed
Incorrect values will be ignored and the width will not be changed
Use karmaHTML.width = null to reset all iframes width CSS style to its default values (to the value defined in the karma config file as client.karmaHTML.width [see above], or - if not defined - to the module default value 90%)
Also check out karmaHTML.index.width property

for(var i=0; i<karmaHTML.length; i++){
  karmaHTML[i].open({width:w[i],height:h[i]});
}

`onstatechange`

Syntax: karmaHTML.onstatechange = function(ready,tag,status,statusText){...}
Return value type: Function | undefined
Description: Take the action when the state of any .html file defined in the karma config file changes.

If you want to observe the particular .html file of chosen tag name, rather than all .html files defined in the karma config file, check out karmaHTML.index.onstatechange property

1. Defining `onstatechange`:

Define onstatechange as a function(). This function() will be automatically fired in the following situations:

the html resources are loaded (the response parameter is passed as true)
the iframe html page is reloaded (the response parameter is passed as true)
the iframe html page is closed (the response parameter is passed as false)
the abort is terminated (the response parameter is passed as false)

tag (String) parameter indicates which .html file's state has been changed
response (Number) parameter passes HTTP numerical response message, eg. 200, 404
responseText (String) parameter passes HTTP textual response message, eg. OK, Not Found

3. Un-defining `onstatechange`:

To stop firing onstatechange defined function(), re-define onstatechange property with any other - than function - value type.

karmaHTML.onstatechange = null;
karmaHTML.onstatechange = false;
karmaHTML.onstatechange = "";

syntax example

karmaHTML.onstatechange = function(ready,tag,status,statusText){
    if(ready) {
       if(tag==='index') run_index_tests();
       if(tag==='tmpl') run_tmpl_tests();
    }
}
karmaHTML.open();

jasmine syntax example

describe("The index.html iframe document",function(){
  beforeAll(function(done){
    karmaHTML.index.onstatechange = function(ready){
      if(ready) done(); //if the #Document is ready, fire tests!
    };
    karmaHTML.index.open();
  });
  it("should be a real Document object",function(){
    var iframeDocument = karmaHTML.index.document;
    expect(iframeDocument.constructor.name).toEqual('HTMLDocument');
  });	
});

The value (eg. '600px') is appended to the iframe element as the attribute style="width:600px"
All valid CSS values and units are allowed
Incorrect values will be ignored and the width will not be changed
Use karmaHTML.index.width = null to reset this iframe width CSS style to its default value (to the value defined in the karma config file as client.karmaHTML.width [see above], or - if not defined - to the module default value 90%)

If you set your karma config file client.karmaHTML.auto property to true, your .html files may be loaded before you define onstatechange property to catch the moment of loading finish. Then you can use the following code, to check out, whether your .html file is already loaded:

if(karmaHTML.index.ready) run_index_tests();

`onstatechange`

Syntax: karmaHTML.index.onstatechange = function(ready,tag,status,statusText){...}
Return value type: Function | undefined

karmaHTML.index.onstatechange = function(ready){
    if(ready) run_index_tests();
}
karmaHTML.tmpl.onstatechange = function(ready){
    if(ready) run_tmpl_tests();
}

karmaHTML.index.open();
karmaHTML.tmpl.open();

Common problems

1. `fs` `glob` Errors in your CMD

If you use Webpack, it is recommended to add node: {fs: "empty"} to your webpack config file, in order to avoid fs module problems when loading karma-html

Examples

1. Test your `.html` files of tag `'index'` and `'tmpl'` separately

karmaHTML.index.onstatechange = function(state){
  if(state){
    run_index_tests();
    this.close(); //or karmaHTML.index.close();
    this._root.tmpl.open(); //or karmaHTML.tmpl.open();
  }
};
karmaHTML.tmpl.onstatechange = function(state){
  if(state){
    run_tmpl_tests();
    this.close(); //or karmaHTML.tmpl.close();
  }
};

karmaHTML.index.open();

Step-by-step configuration

We will use Jasmine framework for testing, Mocha reporter to report our tests results in the terminal, karmaHTML package to test our html files, karma-jasmine-dom package to test DOM objects with DOM custom matchers and Chrome browser to run our html templates for testing. 1. Create new folder New project anywhere and create the following folders and files (empty) structure inside of it:

New project
 ├ tests
 │  └ tests.js
 ├ karma.conf.js
 └ index.html

Open the New project folder and open your terminal there (with the location set to New project folder)
Install neccessary packages with npm by executing the following command:
- npm install karma karma-jasmine jasmine-core karma-chrome-launcher karma-mocha-reporter karma-html karma-jasmine-dom
In the karma.conf.js file add the following content:

module.exports = function(config) {
  config.set({
    files: [
      {pattern: 'tests/*.js',watched:true,served:true,included:true}
    ],
    //load karma-mocha-reporter and karma-html
    reporters: ['mocha','karmaHTML'],
    //load karma-jasmine-dom and karma-jasmine
    frameworks: ['jasmine-dom','jasmine'],
    //load karma-chrome-launcher
    browsers: ['Chrome'],
    client: {
      //If false, Karma will not remove iframes upon the completion of running the tests
      clearContext:false,
      //karma-html configuration
      karmaHTML: {
        source: [
          //indicate 'index.html' file that will be loaded in the browser
          //the 'index' tag will be used to get the access to the Document object of 'index.html'
          {src:'./index.html', tag:'index'}
        ],
        auto: true
      }
    }
  });
};

It should work just fine right now, run karma start in the terminal and it should:
- prompt the positive tests results in the terminal
- open the Chrome browser and display the iframe with our (empty) index.html template
Add the following HTML content example to our index.html file:

<!DOCTYPE html>
<html>
  <head>
    <title>New project</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
  </head>
  <body>
    <h3 id="header">Hello world!</h3>
    <p id="paragraph">This is our html template.</p>
  </body>
</html>

Add the following jasmine test suits into our tests/tests.js file:

//describe, beforeAll, it, expext - are the Jasmine default methods
//karmaHTML is the karma-html package object with the access to all its features

describe("The index.html iframe document",function(){
  
  beforeAll(function(done){
    //load DOM custom matchers from karma-jasmine-dom package
    jasmine.addMatchers(DOMCustomMatchers);
    
    //lets open our 'index.html' file in the browser by 'index' tag as you specified in 'karma.conf.js'
    karmaHTML.index.open();
    
    //karmaHTML.index.onstatechange fires when the Document is loaded
    //now the tests can be executed on the DOM
    karmaHTML.index.onstatechange = function(ready){
      //if the #Document is ready, fire tests
      //the done() callback is the jasmine native async-support function
      if(ready) done();
    };
  });
  
  it("should be a real Document object",function(){
    var _document = karmaHTML.index.document;
    expect(_document.constructor.name).toEqual('HTMLDocument');
  });
  
  it("should contain paragraph and header that are the siblings",function(){
    //karmaHTML.index.document gives the access to the Document object of 'index.html' file
    var _document = karmaHTML.index.document;
    //use all document javascript native methods on it
    var header = _document.getElementById('header');
    var paragraph = _document.getElementById('paragraph');
    
    //these are the karma-jasmine-dom custom matchers
    expect(paragraph).toBeNextSiblingOf(header);
    expect(header).toBePreviousSiblingOf(paragraph);
  });
});

Run karma start again in the terminal and it should:
- prompt the positive two tests results in the terminal
- open the Chrome browser and display the iframe with our index.html template loaded to run the tests on its DOM
Read the documentation above to use all the features of karma-html!
