Thanks for sharing the knowledge. If its not to much to ask I would love to see at least one more video about how you test a database connection and results from queries.
Nice series, I liked it. even though it is about testing and logic of programming has nothing to do with it. a few points. First when calling `set`, logically a programmer will expect a `set` not a `merge`. for merge I would assume an `append` or `merge` is in order. Next dropping items from array because they are not match and accepting the rest is a bad practice, it should throw exception or if a little more polite, return an error message or code. in a complex program if you drop some items silently it will cause headache during debug to figure out why I'm passing 3 object and I am receiving 2 object down the line in a chain of 20 classes (if ever they figure out there is such a bug). One more thing. when writing test, fixed numbers shouldn't be used. testing upon a fixed value, your method might return your expected result (accidentally or intentionally just to make test pass) and your test will pass even though there is a bug in the application. In such situations an array of fixed values or random values if possible should be used.
Can somebody explain what is going on where he passed $addition (a addition class object) to setOperation method having argument OpeartionInterface $operation on calculator class ?? on 2:11 line number 12 ??
a simpler way for setOperations function would be: foreach ($operations as $operation) { if ($operation instanceof OperationInterface) { $this->operations[] = $operation; } }
SublimeText is even lighter than Atom is. (If you are just wanting to get simple work done without all the bells and whistles) You can/should have many tools to choose from depending on the situation, no one thing is the answer!
It is Sublime, both because he used it in the past and also because an orange S logo appears sometimes while deleting files, which is the logo of Sublime. Atom is fine and freeware, Sublime is paid, but if you want to try Atom try Visual Studio Code instead: freeware as well, but better!
here is the updated method for prevent the error use PHPUnit\Framework\TestCase; use App\Calculator\Addition; use App\Calculator\Division; use App\Calculator\Calculator; class CalculatorTest extends TestCase { /** @test */ public function calculateMethodReturnsMultipleResults() { $addition = new Addition(); $addition->setOperands([5, 10]); $division = new Division(); $division->setOperands([50, 2]); $calculator = new Calculator(); $calculator->setOperations([$addition, $division]); $results = $calculator->calculate(); $this->assertIsArray($results); $this->assertEquals(15, $results[0]); $this->assertEquals(25, $results[1]); } }

This series is by far one of the best things that ever happened in my entire life.
Thank you.
Can you my claps. I am standing up and giving a standing ovation and shouting "Encore'.
assertInternalType("array") is deprecated. Now you can use assertIsArray() or its internal types variations;
Wow! I really appreciate for the invested time you've put on this series. I learned a lot. Thanks much
That series was perfect. thanks for sharing such valuable information for free!
Exactly what i need, thanks for this series!
Had to implement Unit testing for a task given for a job application, this helped a lot !
Thanks for the series!
wow! writing test code seems more difficult than functional code. thanks . this was brilliant.
You are AWESOME, and this playlist is great.
Thanks form Egypt :D
Amazing tutorials! Thank you so much!
Brilliant work. Thanks very much for these!
Thank you for this, this will help many people.
This was super helpful for a PHPUnit crash course, thank you! 👏👏👏
$this->assertIsArray( 'array', $calculator->calculate() ); how to solve this problem?
Excellent series! Thank you
Thanks, nice and easy to follow! :)
How do you know that you covered enough tests for a certain class?
Nice! Very helpful. Thank you.
Thanks for the course, great explanation
Amazing tutorial, thanks a lot🙏🔥
Thanks for the much needed refresher! Back to actually writing tests FIRST! lol
great series... thanks a lot
Thanks for sharing the knowledge. If its not to much to ask I would love to see at least one more video about how you test a database connection and results from queries.
Thank you. I enjoyed this series :)
Its really a good tutorial for learners.. Please keep posting for update.
Thank you for this valuable knowledge
I made it till the last video!

so useful videos
Can't Thank You Enough
thanks a lot fot the tutorial
would you please update your code for php latest version . this will help alot.
Why typehint the Interface and not the abstract class ?
Thanks!
a simpler way for setOperations function would be:
foreach ($operations as $operation) {
if ($operation instanceof OperationInterface) {
$this->operations[] = $operation;
}
}
name of this IDE?
Atom, it is a free IDE. I used it too
Wilbert Vos really? i am using Atom but i think this was a different theme.
Yup this is Sublime with the material theme.

here is the updated method for prevent the error
use PHPUnit\Framework\TestCase;
use App\Calculator\Addition;
use App\Calculator\Division;
use App\Calculator\Calculator;
class CalculatorTest extends TestCase
{
/** @test */
public function calculateMethodReturnsMultipleResults()
{
$addition = new Addition();
$addition->setOperands([5, 10]);
$division = new Division();
$division->setOperands([50, 2]);
$calculator = new Calculator();
$calculator->setOperations([$addition, $division]);
$results = $calculator->calculate();
$this->assertIsArray($results);
$this->assertEquals(15, $results[0]);
$this->assertEquals(25, $results[1]);
}
}
