Now imagine, that you have a system with hundreds of methods, and suddenly a bug appears, and you need to track it and resolve it.<\/p>\n\n\n\n
This might take a very long time. It is in situations like this that Code testing and Unit testing in a particular section can help prevent this type of problem.<\/p>\n\n\n\n
So today we are going to discuss it in detail with the PHP development<\/a><\/strong>\u00a0framework Laravel. The Laravel development<\/a> framework is also a PHP Unit testing framework itself.<\/p>\n\n\n\n PHP Unit is one of the most popular and widely useful testing frameworks. PHP Unit allows us to create both kinds of testing-Unit testing and Functional Testing.<\/p>\n\n\n\n We will learn the introduction of Unit and functional testing. Now, we’ll learn how to develop unit testing and functional testing in Laravel.<\/p>\n\n\n\n If you already know about PHP Unit testing, we can divide testing into two different sections- Unit Testing<\/strong> and Functional Testing<\/strong>.<\/strong><\/p>\n\n\n\n Before we go ahead and create an actual test, we need to set up a couple of things that will be used in software testing<\/a><\/strong>. We will create Posts<\/strong> modal and related migration.<\/p>\n\n\n\n Go ahead and run the below command in the terminal.<\/p>\n\n\n\n In the precedent section, we did the initial setup that’s going to be useful to us in this and upcoming sections. In this section, we are going to create an example that demonstrates the concepts of unit testing in Laravel.<\/p>\n\n\n\n Read More:<\/span> A Complete Guide to Events and Listeners in Laravel<\/a><\/p>\n<\/div>\n i.e. I have changed the in a file at ‘tests\/Unit\/PostsTest.php<\/strong>‘. Just replace the code ‘$db_post = DB::select(‘select * from posts where id = 2′);’ in place of ‘$db_post = DB::select(‘select * from posts where id = 1′);’ and run command ‘phpunit<\/strong>‘. You will get the test results below.<\/p>\n\n\n\n So, this is all about unit testing, here we have to share How Laravel develope<\/a>rs<\/a><\/strong> test their own code and how it can help you to better manage and control projects. As part of IT Staff Augmentation, developers leverage the technique of Unit Testing to ensure that their code works as intended by validating individual components and functionalities in isolation.

2. Functional Test<\/h3>\n\n\n\n

Let’s have a quick look at the below Example that’s an ideal case for Unit Testing.<\/h2>\n\n\n\n
