PHP关于assertEquals的解释

Question

Inside of a phpunit test I have a $column variable and $actual fetches a $result from a mysql query. Is it possible to simply explain what the below assertEquals statement is doing with the given info without showing all the code?

$column = 'access_level';

$this->assertEquals($column, $actual['access_level']);

Answer 1

http://phpunit.de/manual/3.7/en/writing-tests-for-phpunit.html#writing-tests-for-phpunit.assertions.assertEquals

assertEquals(mixed $expected, mixed $actual[, string $message = ''])

Reports an error identified ... if the two variables $expected and $actual are not equal.

Which means in your case that reports an error if $column != $actual['access_level']
