Feature: Profile arbitary code execution
|
|
|
|
Scenario: Profile a function that doesn't do anything
|
|
Given a WP install
|

And a wp-content/mu-plugins/lame-function.php file:

|
"""
|

<?php

When I run `wp profile eval 'wp_cli_do_nothing();' --fields=query_time,query_count,cache_ratio,cache_hits,cache_misses,redis_calls,request_time,request_count`
|

Then STDOUT should be a table containing rows:

|
|
| 0s | 0 | | 0 | 0 | 0 | 0s | 0 |

Scenario: Profile a function that makes one HTTP request
|
|
Given a WP install
|
|
|
|
When I run `wp profile eval 'wp_remote_get( "https://www.apple.com/" );' --fields=request_count`

Scenario: Profile calls to the object cache

Given a WP install

Then STDOUT should be a table containing rows:
|
|
| cache_hits | cache_misses |
|
|
| 2 | 0 |
|
|

Scenario: Profile a function calling a hook
|
|
Given a WP install

When I run `wp profile eval "add_filter( 'logout_url', function( $url ) { wp_cache_get( 'foo' ); return $url; }); wp_logout_url();" --hook --fields=hook,cache_hits,cache_misses`

Then STDOUT should be a table containing rows:

Scenario: redis_calls shows 0 when no persistent object cache is active
|
|
Given a WP install
