Atomic Talk Title: Test Dominance in the era of Micro Frontends

Micro frontends are the frontend counterpart to micro services in the backend. With the explosion of digital transformation across the past few years, many enterprises primarily small-medium businesses and large organisations started investing in the web to scale their business in terms of growth. This indirectly led to bloated monoliths which became very difficult to manage over time, in terms of product planning, development, testing, releases and maintenance. As a result, developers and principal architects explored various approaches to break the code apart and manage them better, which brought in the idea of Micro Services, and most importantly Micro Frontends!
In this talk, I would discuss about – what are Micro Frontends, correlate it with some examples, benefits they offer and how can they be tested in the best possible way, so as to deliver & release top-notch product features to production with premium quality, and in an agile manner.

Talk Takeaways

•  All tests must run against the team’s code, in isolation wherever possible and around team boundaries to efficiently test Micro Frontends
•  Use Shadow DOM for new micro-frontends, as it can help eliminate complexities due to leaking styles, if Micro Frontends are mixed with Monolith UIs
•  Same Test Strategy can be used to test monolith applications. It can also be leveraged for testing micro frontends individually
• Each micro frontend must have its own comprehensive suite of automation tests, that would help improve overall code quality
