PMM-4879: defaults-file param by ritbl · Pull Request #171 · percona/pmm-admin

ritbl · 2021-12-23T10:28:35Z

provides extension point to process default params by implementing commands.ApplyDefaults
username and password set via CLI flag have higher priority (e.g. values from defaults file are used only if values are not initialized)

used for tests only

why don't use mock libraries?

@BupycHuk you were asking for it. I use real file in cmd test, but tmp files for commands/management/add_mysql.go
