# var_dump in Codeception

I’ve learnt making my test failures as ablative as possible trying to stick to the philosophy of “writing a test any time I’m tempted to var_dump”.
Sometimes, in a “who watches the watchers” way, what’t under test is the testing component itself.
I was trying to iterate over my WPDb module to suit my latest needs and found myself unable to dump some values to the console for light debugging.
While unit-testing running the test case with PHPUnit will allow me to commit any kind of coding crime and see the results in the terminal but Codeception is way more educated and will hide all that mess for the sake of manners.

## Make Codeception talk

To make Codeception modules “talk” and make debug possible Codeception can be run in debug mode like

codeception run --debug

and anywhere in a module the debug or debugSection methods can be used like

public function haveOrUpdateInDatabase($table, array$data)
{
$query =$this->driver->insertOrUpdate($table,$data);
$this->debugSection('Query',$query);

...

to have clean and proper output on the terminal
