Pull request overview
This PR aims to stabilize the Behat acceptance tests by eliminating flaky, real HTTP requests (notably to audio.com) and replacing them with deterministic mocked responses within the WP-CLI test framework.
Changes:
- Added HTTP request mocking for
audio.comoEmbed discovery infeatures/provider.feature. - Consolidated provider scenarios by removing
features/add-oembed-provider.featureand moving relevant scenarios intofeatures/provider.feature. - Removed multiple
@require-wp-*scenario gates fromfeatures/fetch.featureandfeatures/cache.feature.

|---|---|
| features/provider.feature | Adds mocked audio.com discovery responses, moves provider scenarios here, and adjusts the limited-response-size scenario. |
| features/add-oembed-provider.feature | Deleted (scenarios appear consolidated into features/provider.feature). |
| features/fetch.feature | Removes @require-wp-* gating across scenarios. |
| features/cache.feature | Removes @require-wp-4.9 gating on cache-find scenarios. |

- This PR description focuses on stabilizing audio.com tests via HTTP request mocking, but this file also removes a large number of
@require-wp-*gates (and related WP-version rationale comments). That changes the supported test matrix/scope beyond the stated purpose; please either restore the gates if they’re still needed or update the PR description to reflect the broadened intent.
Background:
Given a WP install
Scenario: Get HTML embed code for a given URL
# Known provider not requiring discovery.
When I run `wp embed fetch https://www.youtube.com/watch?v=dQw4w9WgXcQ --width=500`
Then STDOUT should contain:

The “Discover a provider with limited response size” scenario now makes a real HTTP request to https://developer.wordpress.org/news/. This reintroduces an external dependency and undermines the goal of stabilizing tests via HTTP mocking; it can still be flaky (network, redirects, content changes) and may fail in restricted CI environments. Consider using the HTTP mocking step for this URL too (or keep using the audio.com URL with a mocked HTML response sized to exercise the limit logic).

The docstring in this STDOUT expectation has inconsistent indentation on the audio.com/ line compared to the surrounding docstrings. Depending on how the Gherkin parser dedents docstrings, this can introduce a leading space in the expected substring and make the STDOUT should contain assertion fail unexpectedly.

This change removes the @require-wp-4.9 gates from the embed cache find scenarios, but the PR description doesn’t mention expanding/removing WordPress-version constraints. If the CI matrix still includes WP < 4.9, these scenarios are expected to fail because oembed_cache behavior differs; either keep the gates or document the new minimum supported WP version/testing matrix in the PR.

The PR description lists updates to features/add-oembed-provider.feature, but in this change set the scenarios appear to have been consolidated into features/provider.feature and the separate feature file removed. Please update the PR description (and/or explain the consolidation rationale) so reviewers understand the full scope of the changes.
Six test scenarios were making real HTTP requests to
audio.com, causing intermittent failures when the service was unreachable or slow.Changes
Replaced real HTTP requests with mocked responses using the WP-CLI test framework's HTTP mocking utility:
features/add-oembed-provider.feature: 3 scenariosfeatures/provider.feature: 3 scenarios (same names)Each mock returns an HTML page with valid oEmbed discovery
<link>tags:This eliminates external service dependencies while maintaining test coverage for oEmbed discovery functionality.
