Strategies for Streamlining Elixir Upgrade Testing

Source: youtube.com

In her presentation, Jenny Bramble emphasizes the importance of collaboration between developers and testers to de-risk the process of upgrading legacy Elixir applications. She advises against exhaustive regression testing, which can be time-consuming and resource-intensive, instead recommending a focused approach to identify and conduct the most critical tests. Bramble also highlights the necessity of reading release notes thoroughly, understanding the potential impact of changes on current systems, and crafting specific testing scenarios based on this understanding. Furthermore, she urges the clear documentation of what is not being tested, as much as what is being tested, which includes understanding the risk and consequences of potential missed issues. The talk underlines the benefits of having a clear communication strategy, both for sharing test plans and justifying decisions, in order to build trust and reduce fear around the upgrade process.
