Salesforce is the world’s #1 CRM, and it supports this with constant innovation. There has been no shortage of impressive and powerful features introduced over the last few years, but the emergence of Lightning Web Components (LWC) in 2018 has been incredibly impactful.
But while LWC has been a game changer for programmers, it presents a unique set of testing challenges for teams and new developers with limited coding experience. At Provar, we’ve been working hard to deliver solutions to support LWC testing — today, tomorrow, and every upcoming Salesforce release.
In this blog, we’ll give some background on LWC, outline what makes them so tricky to test, and discuss how Provar’s robust suite of automation tools can alleviate these challenges.
What Is LWC?
LWC are modern UI frameworks for building web components and applications on the Salesforce platform. Upon its induction, LWC aimed to offer a more efficient, reliable, and robust way to develop web applications in Salesforce.
Why Are LWC Tough To Test?
LWC offers incredible advantages regarding performance, reliability, and development speed. But they are also notoriously tricky to test. This has nothing to do with any inherent flaws to the framework; LWC is complex, and those complexities translate to testing challenges.
Here are some of the challenges that LWC testing presents.
Complexity of Component Interactions
LWCs are often composed of many interconnected components. Testing these components requires setting up complex interactions, making writing repeatable, reliable tests a real challenge.
XPath and CSS Locator Limitations
Many traditional XPath and CSS locators used to test LWC will be unable to find elements. Often, Shadow DOM encapsulates web components, making them private and undetectable by XPath and CSS locators — and ultimately causing tests to fail.
Steep Learning Curve for LWC Testing
For citizen testers and developers new to testing LWC, understanding the best practices and strategies for effective and efficient testing can be a steep learning curve.
