Cache multisite installations like single site installations - #382
Given a WP multisite install restored the cached single site installation and then ran wp core install-network in every scenario. The network installation is now part of the cached installation, keyed by its type, so multisite scenarios restore it the same way single site scenarios do.
Each draft pull request below points wp-cli/wp-cli-tests at this branch. Its Testing workflow ran through workflow_dispatch, together with the same workflow on an unchanged copy of the default branch, three times each where possible. Times are the Run Behat step summed over the matrix jobs that ran in every measured run (median over runs, in job minutes). Retried jobs passed only because behat-rerun repeated their failed scenarios.
Scenarios that failed at least once in a measured run, including runs where behat-rerun then passed them.

Summary by CodeRabbit
Tests
Added coverage for restoring cached multisite installations in both subdirectory and subdomain modes, including validation of the reported network type and site count.
Added a scenario confirming that creating a site on a cached subdomain installation reports subdomain mode and updates the site count to two.
Added checks ensuring cached installations retain the expected network configuration and site totals.

- Line 510: Replace the inline PHP passed to `wp eval` in the `wpmu_create_blog`
step and the related mode checks with PHP files invoked through `wp eval-file`,
so the commands work with Windows command-line quoting.

Walkthrough
The multisite installation helper now accepts a network type and uses it in the installation cache key. The multisite step passes the selected type to the helper. New scenarios check cached subdomain and subdirectory installations.
install_wp() accepts a network type, includes it in the cache key, and runs wp core install-network on cache misses. The multisite step passes the selected network type to the helper.
New scenarios check cached subdomain and subdirectory installations. One subdomain scenario adds a site and verifies that the installation has two sites.
Issue 383 tracks caching recurring setup patterns, including multisite network installations. This change implements caching for that pattern.
Suggested reviewers:swissspidy
Merge Risk: Moderate · previous review 57f58
The new multisite cache scenarios are likely to fail on Windows because of shell quoting, and they may run on WordPress versions that lack get_sites. The network cache could also capture state left over from an earlier step in the same scenario. Fix the Windows-compatible commands and the version gating before merging, and confirm that the cache is built from a clean installation.

Explanation
Issue #377 requires cached multisite installations, with separate cache entries for installation type. FeatureContext::install_wp() now accepts $network, adds the network type to the cache key, and runs wp core install-network only when the cache entry is created. given_a_wp_multisite_installation() now delegates to this method. Added Behat scenarios verify subdirectory and subdomain restoration, site counts, and subdomain behavior. The reported performance variance does not create an additional coding requirement.

Explanation
The changed source code implements issue #377. The cache-key update and conditional network installation create the required cached multisite entries. The step-definition change removes the repeated per-scenario network installation. The added features/behat-steps.feature scenarios test the new cache behavior. The supplied change summary shows no unrelated production changes or tests.

Gate these scenarios by WordPress version.
wp_insert_site() requires WordPress 5.1, and get_sites() requires 4.6. The current tags allow these scenarios to run on older versions, where they fail with undefined-function errors. (developer.wordpress.org)
Add @require-wp-5.1 to the first scenario and @require-wp-4.6 to the other two, or use compatible APIs.

Build the network cache from a clean installation.
If a scenario first creates a single-site installation, changes an option, and then requests the first multisite installation of that type, this new key misses. wp core install leaves the existing installation in place, so the network conversion and cache include that scenario’s changes. Later scenarios restore those changes. (raw.githubusercontent.com)
Restore a clean single-site snapshot before building a network cache entry.

Use Windows-compatible command arguments.
On Windows, cmd.exe does not use single quotes to group the PHP expression. These commands fail instead of passing the expression to wp eval. The mode checks on Lines 504, 520, and 535 have the same problem and fail first. Use PHP files with wp eval-file for these checks and the changed commands. (php.net)
