Here, we will learn how to write the tests using the PHPUnit. First of all, we have to download the composer installer in our\u00a0root\u00a0folder\u00a0using the command:<\/p>\n

curl -s http:\/\/getcomposer.org\/installer | php<\/pre>\n
Then, we have to create a composer.json file in the root and put the following lines into it:<\/p>\n
{\r\n    \"require\": {\r\n        \"phpunit\/phpunit\": \"4.0.*\"\r\n    }\r\n}<\/pre>\n
Here, I used version 4.0.* instead of 5.0.* because version 5 requires PHP version 5.6 but I could only afford\u00a0version 5.5.9.<\/p>\n
After pasting the above lines, we have to install the dependencies using the command:<\/p>\n
php composer.phar install<\/pre>\n
It will create a vendor folder by default in which the PHPUnit\u00a0packages will be stored.<\/p>\n
Now, create a folder in which all the code files will be placed and a folder named Test need to be created parallel to those files in which all the files containing tests will be placed.<\/p>\n
The file name and the class name of the tests should be same. The class name must end with ‘Test’ and function name must start with ‘test’. So, the class name will look like ‘class_nameTest’ and function name will look like ‘testfunction_name’.<\/p>\n
So, here I have created a file name OneTest.php in the Test folder and the code placed in this file is as follows:<\/p>\n
<?php\r\n\r\nnamespace phpUnitTutorial\\Test;\r\n\r\nclass OneTest extends \\PHPUnit_Framework_TestCase\r\n{\r\n public function testTrue()\r\n {\r\n $foo = true;\r\n $this->assertTrue($foo);\r\n }\r\n \/**\r\n * @test\r\n *\/\r\n public function failure()\r\n {\r\n $foo1 = array(1, 2, 3, 4, 5, 6);\r\n $foo2 = array('1', 2, 33, 4, 5, 6); \/\/ taken from the php unit docs\r\n\r\n $this->assertEquals($foo1,$foo2);\r\n }\r\n}<\/pre>\n
You can also write @test in php docs so that it will recognize it as test function even if it don’t have the prefix ‘test’ like I did in second function.<\/p>\n
After writing tests, you have to create a XML file named phpunit.xml in the root folder which represents the path of the test files. Here, I have created a file named phpunit.xml as:<\/p>\n
<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<phpunit colors=\"true\">\r\n <testsuites>\r\n <testsuite name=\"Application Test Suite\">\r\n <directory>.\/phpUnitTutorial\/Test\/<\/directory>\r\n <\/testsuite>\r\n <\/testsuites>\r\n<\/phpunit><\/pre>\n
Now after doing so, you have to run test in the\u00a0Terminal as:<\/p>\n
vendor\/bin\/phpunit\u00a0\r\n<\/pre>\n
Here are a few outputs of tests performed:<\/p>\n
\"phpunitnotestfound\"<\/p>\n
When no test class was found<\/p>\n
\"phpunitsuccess\"<\/p>\n
While making tests\u00a0over the first function in the test\u00a0file<\/p>\n
\"phpunitfailure\"<\/p>\n
While\u00a0making tests over both the functions in the test file<\/p>\n
