Quality Engineering: What the Discipline Becomes in 2026
Quality engineering was the shift from testing software to building systems that produce quality. When agents generate most of the code, the job moves again: from writing the checks to designing what counts as evidence.
Selenium Testing in 2026: When It Is Still the Right Answer
Selenium is twenty years old, drives every browser through a standard, and runs in six languages. Those are real advantages. The cost is that everything modern frameworks give you for free, you assemble yourself.
Shift Left Testing: What It Means When Agents Write the Code
Moving testing earlier was always the right idea and mostly failed on economics: writing tests early cost developer time nobody had. When the agent writing the feature can also verify it, that constraint changes.
Smoke Testing: The Check That Should Never Be Slow
A smoke test answers one question: is this build broken badly enough that nothing else is worth running? Its whole value is speed, and the usual failure is letting it grow until nobody wants to wait for it.
Subagents: When Splitting the Context Actually Helps
A subagent is a separate context window doing isolated work. It solves a specific problem, context pollution on long tasks, and it is regularly reached for when a simpler mechanism would have been better.
Test Data Management: The Unglamorous Reason Suites Fail
Most flaky end-to-end tests are not timing problems. They are data problems: tests that assume a record exists, or leave one behind that breaks the next run.
