LineWeb QA Mixed Media Boundary

This production quality assurance course validates mixed-media delivery and commercial access boundaries without completing any real payment. The curriculum combines a directly hosted MP4 resource, an approved public YouTube lesson, a written scenario, and ordered sections. The opening section checks that a free preview can be played before purchase, that the player presents a stable aspect ratio, and that the surrounding layout remains usable on common screen sizes. The protected section checks that paid content is not exposed to a learner who has not purchased or otherwise received access. It also verifies that the course page presents a clear commercial call to action, while the learning route refuses unauthorized access. The written scenario asks the learner to compare free preview behaviour with enrolled behaviour and document any inconsistency. This course is deliberately priced only to exercise cart and checkout boundaries. Testers must not enter payment information, submit an order to a provider, or simulate a successful charge. The expected outcome is that free preview media loads from the SwapED domain, protected media remains unavailable before access is granted, and course metadata stays consistent across the listing, detail page, instructor panel, and cart. The course should preserve section order, content status, accessibility flags, duration, and price after publication. The learner must not be able to alter progress for content belonging to another course, create discounts, access instructor editing routes, or retrieve hidden materials by changing an identifier. On mobile layouts, embedded and hosted video players should fit the available width without horizontal clipping. The cart should remain fully visible and its controls should not overlap. If checkout is reached, only presentation, navigation, validation messages, and the absence of debug strings may be inspected. No transaction should be finalized. Findings should record the role, URL, viewport, content item, expected behaviour, actual behaviour, and whether a clean refresh changes the result. The course contains only synthetic QA content and approved public or first-party media.
