What you want is the `.at(index)` method: [.at(index)][1] .

So, for your example:

`expect(component.find(&#39;MyInnerComponent&#39;).at(1)).toHaveProp(&#39;title&#39;, &#39;Good-bye&#39;);`


  [1]: http://airbnb.io/enzyme/docs/api/ShallowWrapper/at.html

If you are to test certain things **_on each one_** also consider iterating through the matched set:

    component.find(&#39;MyInnerComponent&#39;).forEach( (node) =&gt; {
        expect(node.prop(&#39;title&#39;)).toEqual(&#39;Good-bye&#39;)
    })

     const component = wrapper.find(&#39;MyInnerComponent&#39;).at(1); 
     //at(1) index of element 0 to ~
  
     expect(component.prop(&#39;title&#39;)).to.equal(&#39;Good-bye&#39;);

TL;DR;

use **findAll** along with **.at(1)**

    const innerComponent = component.findAll(&#39;MyInnerComponent&#39;).at(1);
    expect(innerComponent).toHaveProp(&#39;title&#39;, &#39;Good-bye&#39;);


What are the differences between [Yarn][1] and NPM?
At the time of writing this question I can only find some articles on the Internet showing what&#39;s the Yarn equvalent of an NPM command like [this][2].
  
Do they have the same functionalities (I know Yarn does local caching and looks like you only need to download a package once) but other than this is there any benefits for moving from NPM to Yarn?

I know that most decimals don&#39;t have an exact floating point representation (https://stackoverflow.com/questions/588004).

But I don&#39;t see why `4*0.1` is printed nicely as `0.4`, but `3*0.1` isn&#39;t, when
both values actually have ugly decimal representations:

    &gt;&gt;&gt; 3*0.1
    0.30000000000000004
    &gt;&gt;&gt; 4*0.1
    0.4
    &gt;&gt;&gt; from decimal import Decimal
    &gt;&gt;&gt; Decimal(3*0.1)
    Decimal(&#39;0.3000000000000000444089209850062616169452667236328125&#39;)

Why does the floating-point value of 4*0.1 look nice in Python 3 but 3*0.1 doesn&#39;t?

I&#39;m testing a React component with Jasmine Enzyme shallow rendering.

Simplified here for the purposes of this question...

    function MyOuterComponent() {
      return (
        &lt;div&gt;
          ...
          &lt;MyInnerComponent title=&quot;Hello&quot; /&gt;
          ...
          &lt;MyInnerComponent title=&quot;Good-bye&quot; /&gt;
          ...
        &lt;/div&gt;
      )
    }

`MyOuterComponent` has 2 instances of `MyInnerComponent` and I&#39;d like to test the props on each one.  

The first one I know how to test.  I use `find` with `first`...

    expect(component.find(&#39;MyInnerComponent&#39;).first()).toHaveProp(&#39;title&#39;, &#39;Hello&#39;);

However, I&#39;m struggling to test the second instance of `MyInnerComponent`.

I was hoping something like this would work...

    expect(component.find(&#39;MyInnerComponent&#39;).second()).toHaveProp(&#39;title&#39;, &#39;Good-bye&#39;);

or even this...

    expect(component.find(&#39;MyInnerComponent&#39;)[1]).toHaveProp(&#39;title&#39;, &#39;Good-bye&#39;);

But of course neither of the above work.  

I feel like I&#39;m missing the obvious.  

But when I look through the [docs](http://airbnb.io/enzyme/docs/api/shallow.html) I don&#39;t see an analogous example.

Anyone?

How do you include a space before the closing tags in self closing tags with WebStorm/IntelliJ-based products?

Default settings turns `&lt;ReactComp /&gt;` to `&lt;ReactComp/&gt;`, which is against one of the rules ([jsx-space-before-closing][1]) in the commonly used AirBNBs Javascript style guide.

How can I load image from local directory and include it in ```reactjs img src``` tag?

I have an image called ```one.jpeg``` inside the same folder as my component and I tried both ```&lt;img src=&quot;one.jpeg&quot; /&gt;``` and ```&lt;img src={&quot;one.jpeg&quot;} /&gt;``` inside my ```render```function but the image does not show up. Also, I do not have access to ```webpack config``` file since the project is created with the official ```create-react-app``` command line util.


Update: This works if I first import the image with ```import img from &#39;./one.jpeg&#39;``` and use it inside ```img src={img}```, but I have so many image files to import and therefore, I want to use them in the form, ```img src={&#39;image_name.jpeg&#39;}```. 

How do I reference a local image in React?

Updated for TypeScript 2.1
====

[TypeScript 2.1 now supports object spread/rest][1], so no workarounds are needed anymore!

----------


Original Question
----

TypeScript supports [JSX spread attributes][2] which is commonly used in React to pass HTML attributes from a component to a rendered HTML element:

    interface LinkProps extends React.HTMLAttributes {
      textToDisplay: string;
    }
    
    class Link extends React.Component&lt;LinkProps, {}&gt; {
      public render():JSX.Element {
        return (
          &lt;a {...this.props}&gt;{this.props.textToDisplay}&lt;/a&gt;
        );
      }
    }

    &lt;Link textToDisplay=&quot;Search&quot; href=&quot;http://google.com&quot; /&gt;

However, React introduced a [warning if you pass any unknown props to an HTML element][3]. The above example would produce a React runtime warning that `textToDisplay` is an unknown prop of `&lt;a&gt;`. The suggested solution for a case like this example is to use [object rest properties][4] to extract out your custom props and use the rest for the JSX spread attributes:

    const {textToDisplay, ...htmlProps} = this.props;
    return (
      &lt;a {...htmlProps}&gt;{textToDisplay}&lt;/a&gt;
    );

&lt;s&gt;But TypeScript does not yet support this syntax. I know that hopefully some day [we will be able to do this in TypeScript][5].&lt;/s&gt; (***Update**: [TS 2.1 now supports object spread/rest][1]! Why are you still reading this??*) In the meantime what are some workarounds? I&#39;m looking for a solution that doesn&#39;t compromise type-safety and finding it surprisingly difficult. For example I could do this:

    const customProps = [&quot;textDoDisplay&quot;, &quot;otherCustomProp&quot;, &quot;etc&quot;];
    const htmlProps:HTMLAttributes = Object.assign({}, this.props);
    customProps.forEach(prop =&gt; delete htmlProps[prop]);

But this requires the use of string property names that are not validated against the actual props and thus prone to typos and bad IDE support. Is there a better way we can do this?

In React, are there any real differences between these two implementations?
Some friends tell me that the `FirstComponent` is the pattern, but I don&#39;t see why. The `SecondComponent` seems simpler because the render is called only once.

First:

    import React, { PropTypes } from &#39;react&#39;
    
    class FirstComponent extends React.Component {
    
      state = {
        description: &#39;&#39;
      }
    
      componentDidMount() {
        const { description} = this.props;
        this.setState({ description });
      }
    
      render () {
        const {state: { description }} = this;    
        return (
          &lt;input type=&quot;text&quot; value={description} /&gt; 
        );
      }
    }
    
    export default FirstComponent;

Second:

    import React, { PropTypes } from &#39;react&#39;
    
    class SecondComponent extends React.Component {
    
      state = {
        description: &#39;&#39;
      }
    
      constructor (props) =&gt; {
        const { description } = props;
        this.state = {description};
      }
    
      render () {
        const {state: { description }} = this;    
        return (
          &lt;input type=&quot;text&quot; value={description} /&gt;   
        );
      }
    }
    
    export default SecondComponent;


Update:
I changed `setState()` to `this.state = {}` (thanks joews), However, I still don&#39;t see the difference. Is one better than other?

React component initialize state from props

I have the following function in a React component:

    onUploadStart(file, xhr, formData) {
      formData.append(&#39;filename&#39;, file.name);
      formData.append(&#39;mimeType&#39;, file.type);
    }

This is my test that at least gets the spy to be called: 

    const formData = { append: jest.fn() };
    const file = { name: &#39;someFileName&#39;, type: &#39;someMimeType&#39; };
    eventHandlers.onUploadStart(file, null, formData);

    expect(formData.append).toHaveBeenCalledWith(
      [&#39;mimeType&#39;, &#39;someMimeType&#39;],
      [&#39;fileName&#39;, &#39;someFileName&#39;]
    );

However, the assertion is not working:

    Expected mock function to have been called with:
     [[&quot;mimeType&quot;, &quot;someMimeType&quot;], [&quot;fileName&quot;, &quot;someFileName&quot;]]
    But it was called with:
      [&quot;mimeType&quot;, &quot;someMimeType&quot;], [&quot;filename&quot;, &quot;someFileName&quot;]

What is the right way to use `toHaveBeenCalledWith`?

I&#39;m trying to add unit tests to my Angular 2 app. In one of my components, there is a button with a `(click)` handler. When the user clicks the button a function is called which is defined in the `.ts` class file. That function prints a message in the console.log window saying that the button has been pressed. My current testing code tests for printing of the `console.log` message:

    describe(&#39;Component: ComponentToBeTested&#39;, () =&gt; {
        var component: ComponentToBeTested;

        beforeEach(() =&gt; {
            component = new ComponentToBeTested();
            spyOn(console, &#39;log&#39;);
        });

        it(&#39;should call onEditButtonClick() and print console.log&#39;, () =&gt; {
            component.onEditButtonClick();
            expect(console.log).toHaveBeenCalledWith(&#39;Edit button has been clicked!);
        });
    });

However, this only tests the controller class, not the HTML. I don&#39;t just want to test that the logging happens when `onEditButtonClick` is called; I also want to test that `onEditButtonClick` is called when the user clicks the edit button defined in the component&#39;s HTML file. How can I do that?

Unit testing click event in Angular

I get that `.toEqual()` checks equality of all fields for plain objects:

```typescript
expect(
	{&quot;key1&quot;:&quot;pink  wool&quot;,&quot;key2&quot;:&quot;diorite&quot;}
).toEqual(
	{&quot;key2&quot;:&quot;diorite&quot;,&quot;key1&quot;:&quot;pink wool&quot;}
);
```

So this passes.

But the same is not true for arrays:

```typescript
expect([&quot;pink wool&quot;, &quot;diorite&quot;]).toEqual([&quot;diorite&quot;, &quot;pink wool&quot;]);
```

There does not seem to be a matcher function that does this in the jest docs, i.e. that tests for the equality of two arrays irrespective of their elements positions. Do I have to test each element in one array against all the elements in the other and vice versa? Or is there another way?


Is there an Array equality match function that ignores element position in jest.js?

I&#39;m fairly new to the Javascript world (coming from Android) so I&#39;ve been reading up on how to setup Mocha/Jasmine to get my test environment in place.  I&#39;ve noticed a convention of &quot;spec&quot; in reference to test directories, file suffix, suite names, and/or tests/assertions.  

Is this specific to testing in Javascript?  And what does &quot;spec&quot; actually stand for?  Specification, Expectation, or ?

I am trying to test a style attribute for a React component. What is the best way to get style params in the test?

At this moment, my best option is to test if the HTML includes the string, but I think there is a better option.

Case:

How to unit test a method of react component?

Hy, I don&#39;t know how to mock an inline function in React component&#39;s child

My stack: `sinon`, `chai`, `enzyme`; 

Component usage:

    &lt;ListItem onClick={() =&gt; someFn()} /&gt;

Component&#39;s render:

    render() {
        return (
          &lt;li&gt;
            &lt;a href=&quot;#&quot; onClick={e =&gt; {
                e.preventDefault();
                this.props.onClick();
              }}
            &gt; whatever &lt;/a&gt;
          &lt;/li&gt;
        );
      }

Here we have `onClick` function that calls `e.preventDefault()`. How to tell to `&lt;a href&gt;`(`link`) to not to call `e.preventDefault()`? How can I mock an `onClick`?

Below is what I have tried in tests:

Shallow copy setup

    function setup() {
      const someFn = sinon.stub();
    
      const component = shallow(
        &lt;ListItem
          onClick={() =&gt; {
            someFn();
          }}
        /&gt;
      );
    
      return {
        component: component,
        actions: someFn,
        link: component.find(&#39;a&#39;),
        listItem: component.find(&#39;li&#39;),
      }
    }

And the test

      it(&#39;simulates click events&#39;, () =&gt; {
        const { link, actions } = setup();
        link.simulate(&#39;click&#39;); //Click on &lt;a href&gt;
        expect(actions).to.have.property(&#39;callCount&#39;, 1); //will be fine if we remove e.preventDefault()
      });

Test&#39;s output error:

    TypeError: Cannot read property &#39;preventDefault&#39; of undefined

How to mock e.preventDefault in react component&#39;s child

I have a react component(this is simplified in order to demonstrate the issue):

    class MyComponent extends Component {
        handleNameInput = (value) =&gt; {
            this.searchDish(value);
        };
        
        searchDish = (value) =&gt; {
          //Do something
        }
    
        render() {
            return(&lt;div&gt;&lt;/div&gt;)
        }
    }

Now I want to test that `handleNameInput()` calls `searchDish` with the provided value.

In order to do this I would like to create a [jest mock function][1] that replaces the component method.

Here is my test case so far:

    it(&#39;handleNameInput&#39;, () =&gt; {
       let wrapper = shallow(&lt;MyComponent/&gt;);
       wrapper.searchDish = jest.fn();
       wrapper.instance().handleNameInput(&#39;BoB&#39;);
       expect(wrapper.searchDish).toBeCalledWith(&#39;BoB&#39;);
    })

But all I get in the console is `SyntaxError`:

&gt; SyntaxError
&gt;       
&gt;       at XMLHttpRequest.open (node_modules/jsdom/lib/jsdom/living/xmlhttprequest.js:458:15)
&gt;       at run_xhr (node_modules/browser-request/index.js:215:7)
&gt;       at request (node_modules/browser-request/index.js:179:10)
&gt;       at DishAdmin._this.searchDish (src/main/react/components/DishAdmin.js:155:68)
&gt;       at DishAdmin._this.handleNameInput (src/main/react/components/DishAdmin.js:94:45)
&gt;       at Object.&lt;anonymous&gt; (src/main/react/tests/DishAdmin.test.js:122:24)


So my question is, how do I properly mock component methods with enzyme?

How to mock React component methods with jest and enzyme

I recently wanted to test that some custom method gets conditionally called in the `componentDidMount` method of a React component.

    componentDidMount() {
      if (this.props.initOpen) {
        this.methodName();
      }
    }

I&#39;m using Jest as my testing framework, which includes `jest.fn()` for mocks/spies.  I&#39;ve read that this would be fairly trivial to test with Sinon, by doing something like the following:

    sinon.spy(Component.prototype, &quot;methodName&quot;);
    const wrapper = mount(&lt;Component {...props} /&gt;);
    expect(wrapper.instance().methodName).toHaveBeenCalled();

I&#39;m trying to recreate this with Jest like so:

    Component.prototype.methodName = jest.fn();
    const wrapper = mount(&lt;Component {...props} /&gt;);
    expect(wrapper.instance().methodName).toHaveBeenCalled();

This code fails and throws the following error:

    jest.fn() value must be a mock function or spy.
    Received:
      function: [Function bound mockConstructor]

Is it possible to test this functionality with Jest? And if so, how?
