In this episode, Russell, Tara, Ben Dowen, and Al Goodall explore end-to-end testing.

Starting with some light-hearted banter on coffee, triggered by Ben.

From what start to what end?

A recurring theme is being clear with what we mean when we say end-to-end

The group reflect on:

• Using a term alongside terms like user journey and which user
• Being clear about what 'flow' is being tested
• Not to test everything
• Is it a sign of low testability and a smell of something

Integrations

Often, these tests cross architecture and boundaries, and check some form of integration

• Use the smallest unit of test to validate your goal
• End-to-End tests are expensive - time, effort, fragility, environments
• Help reduce risk as ownership crosses teams in modern systems
• They find important failures
