What are the elements of the first argument passed to assertValidationErrors?

[thedamnedrhino]

assertValidationErrors() is supposed to get an array of fields as it's first argument, However it is not clear how those field are supposed to be identified. In the docs there is data.email, now email is the field name but what is data? The Form Name?

I get very strange behaviour related to this, in a form containing both a threshold field and name field. threshold is a number field, and name is a text field. And both of them have only the NotBlank Constraint. Now providing the following values:

$form['material[threshold]'] = '';
$form['material[name]'] = '';

The only way to get assertValidationErrors() to pass is the following:

$this->assertValidationErrors(['children[threshold]', 'children[name].data'], $this->client->getContainer());

notice the .data after children[name]

I don't remember why but the .data has to been used during tests too: https://github.com/liip/LiipFunctionalTestBundle/blob/97cedfc1edd51e142044f2db3759bd96ef7a9d5a/Tests/Test/WebTestCaseTest.php#L541

If we look at the code called by the assertValidationErrors() function, we can see that it mostly reuse Symfony components: https://github.com/liip/LiipFunctionalTestBundle/blob/97cedfc1edd51e142044f2db3759bd96ef7a9d5a/Test/ValidationErrorsConstraint.php https://github.com/liip/LiipFunctionalTestBundle/blob/e3ee7666c2a3fba5e4f1fd0c6887362d91bed889/Validator/DataCollectingValidator.php

And .data is not explicitely defined in this Bundle.

So it looks like the .data comes from Symfony's own code.
