Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.

Readme
When working with Testing Library within a large project often you need to wrap your component in several providers:
const history = createMemoryHistory();
const locale = 'en';
const user = {name: 'Giorgio'};
render(
<Router history={history}>
<IntlProvider locale={locale}>
<UserContext.Provider value={user}>
<MyComponent />
</UserContext.Provider>
</IntlProvider>
</Router>,
);
This can lead to a lot of overhead and is not very flexible.
Render Composer allows you to declare reusable and configurable wraps that define a single provider. These wraps can then be combined to generate more complex hierarchies.
const RouterWrap = wrap((children, {history}) => (
<Router history={history}>{children}</Router>
)).defaultData(() => ({
history: createMemoryHistory(),
}));
const IntlWrap = wrap((children, {locale}) => (
<IntlProvider locale={locale}>{children}</IntlProvider>
)).defaultData({locale: 'en'});
const UserWrap = wrap((children, {user}) => (
<UserContext.Provider value={user}>{children}</UserContext.Provider>
)).defaultData({user: {name: 'Giorgio'}});
const appRender = RouterWrap.wraps(IntlWrap)
.wraps(UserWrap)
.withRenderMethod(render);
appRender(<MyComponent />);
With NPM:
npm install @gpx/render-composer --save-dev
With Yarn:
yarn add @gpx/render-composer --dev
Now simply import it in your tests:
import wrap from '@gpx/render-composer';
// or
var wrap = require('@gpx/render-composer');
You can create a wrap with the wrap
method:
const Wrap = wrap((children, data) => <div>{children}</div>);
data
is an empty object by default. You can set some default values with defaultData
:
Wrap.defaultData({foo: 'bar'});
If you need the data to be generated every time rather than be static you can also
pass a function to defaultData
:
Wrap.defaultData(() => ({foo: Math.random()}));
You can compose the wraps with the wraps
method. You can chain as many wraps you want:
WrapA.wraps(WrapB)
.wraps(WrapC)
.wraps(WrapD);
Once you are satisfied with your wrap you can get a render method with withRenderMethod
:
import {render} from '@testing-library/react';
const renderWrap = Wrap.withRenderMethod(render);
renderWrap(<MyComponent />);
The generated render method will also accept data to overwrite the default values you defined in your wraps. The data will be returned too:
Wrap.defaultData(() => ({foo: 'bar'}));
// This `foo` will have value `'bar'`
const {foo} = renderWrap(<MyComponent />);
// This `foo` will have value `'baz'`
const {foo} = renderWrap(<MyComponent />, {foo: 'baz'});
Note that wraps are immutable so that they can be defined in one file and exported and combined.
