codeception-debug-log

Modules:

CheckDebugLog

Checks if debug.log of WordPress has been created between tests. If yes, it copies the file to codeception/_output

WPCliDb:

Uses wp-cli commands to reset, import, replace URLs and handle transients for database dumps after those are imported to a WordPress test site.
Also, exports a db dump in case tests fail.

Example usage in codeception.yml:

CheckDebugLog:   
    WPpath: ''
WPCliDb:   
    dump: codeception/_data/dump.sql
    cleandump: codeception/_data/cleandb.sql
    dump1: codeception/_data/germandefault.sql
    dump2: codeception/_data/german-default-no-english.sql
    oldUrl: 'http://old.dev'
    newUrl: 'http://new.dev'

Those dumps can be loaded at the beginning of a test as:

start_with_a_clean_site() //loads "cleandump"
start_with_dump1() //loads "dump1"
start_with_dump2() //loads "dump2"
