assertEquals
Checks that two variables are equal. If you’re comparing floating-point values, you can specify the optional “delta” parameter which dictates how great of a precision error are you willing to tolerate in order to consider the two values equal.
Regular example:
<?php $I->assertEquals($element->getChildrenCount(), 5);
Floating-point example:
<?php $I->assertEquals($calculator->add(0.1, 0.2), 0.3, 'Calculator should add the two numbers correctly.', 0.01);

expectException
Handles and checks exception called inside callback function. Either exception class name or exception instance should be provided.
<?php $I->expectException(MyException::class, function() { $this->doSomethingBad(); }); $I->expectException(new MyException(), function() { $this->doSomethingBad(); });
If you want to check message or exception code, you can pass them with exception instance:
<?php // will check that exception MyException is thrown with "Don't do bad things" message $I->expectException(new MyException("Don't do bad things"), function() { $this->doSomethingBad(); });
-
