Visual testing is a quality assurance discipline that consists in automatically comparing the rendered output of an interface between two versions, to detect regressions invisible to classic functional tests. Where a unit test verifies that a function returns the right value, a visual test verifies that what the user sees stays consistent with what was intended.
This page gathers articles from the Delta-QA blog dedicated to visual testing across all its facets: comparison methods (pixel by pixel, perceptual, structural), market tools, integration into CI/CD pipelines, measurable ROI for QA teams. Whether you are discovering the discipline or seeking to industrialize your practice, you will find here the guides, comparisons and field feedback to move forward.
Delta-QA is a no-code visual testing tool, with an On-Premise option — the purpose of this blog is also to honestly share the strengths and limits of each approach, without hiding the trade-offs.
