Version Control

This repository is a monorepo managed by Lerna. This means that all components are centrally managed here, even though we publish them to NPM as separate packages.

Testing in create react app v3+

If you want to have Jest tests in Create React App here an example on how we added them: commit link to patterns library examples. Keep in mind that this is just an example and some configs might not be needed for your case.

Refering to the commit diff: cleaner would be to have, instead of the .babelrc that adds the babel preset "@babel/react", the preset directly inside config/jest/jestPreprocess.js

Testing with Selenium, Testcafe and other UI testing tools

By default, pattern-library web components make use of ShadowDOM. To trigger interactions inside such web component you need to access the DOM via the ShadowRoot. Schematically, this works like this: UI Testtool -> Driver -> native DOM selector -> ShadowRoot -> querySelector

Here is a concrete example in Java using Selenium:

public WebElement expandRootElement(WebElement element, WebDriver driver) {
    WebElement ele = (WebElement) ((JavascriptExecutor) driver)
            .executeScript("return arguments[0].shadowRoot",element);
    return ele;
}

Calling this method gives you the ShadowRoot in your Selenium environment. Beware: when calling findElement on the return value of expandRootElement only the following selectors will work:

• By.id
• By.className
• By.cssSelektor

Dealing with F(lash) O(f) U(nstyled) C(ontent)

As described in ARCHITECTURE.md, FOUC can be mitigated by using the CSSpseudo selector: :not(:defined). Below please find an example of how we can show to the user that the <axa-footer> is not yet defined (pulsating blocks). The selector :not(:defined) won't work in IE11 and therefore there won't have any effect on it. Following the principle of graceful degradation, this if fine, since the only downside in IE11 is that it doesn't look as good as the other browsers while no real functionality has been lost.

<style>
  axa-footer:not(:defined) {
    background-color: #3b3fd8;
    color: #3b3fd8;
    display: block;
  }

  axa-footer:not(:defined) svg {
    display: none;
  }

  axa-footer:not(:defined) a {
    color: #FFF;
    background: #FFF;
    display: inline-block;
    margin-left: 10px;
    pointer-events: none;
    margin-top: 10px;
    opacity: 0.2;
    transition:opacity 500ms ease-out;
    animation: pulseloadingaxafooter 1s infinite;
  }

  @keyframes pulseloadingaxafooter {
  0% {
    opacity: 0.2;
  }
  50% {
    opacity: 0.3;
  }
  100% {
    opacity: 0.2;
  }
}
</style>
