In previous post PHPUnit Basic Tutorial<\/a> we learned overview of  PHPUnit.<\/p>\n\n\n\n

Now in this post we Write a test class and execute it and read output of test result.
Step 1#<\/strong>: Create a test class named as SampleClass in file named SampleClass.php
this class contain a method for division of two numbers<\/p>\n\n\n\n

<?php\nclass SampleClass\n{\n    public function divideNumber($a=null,$b=null){\n        $c=$a\/$b;\n        return $c;\n    }\n}\n\n?><\/pre>\n\n\n\n
Step 2#:<\/strong>now we write a test named SampleClassTest in file named SampleClassTest.php
for above class<\/p>\n\n\n\n
<?php\n\nrequire_once('SampleClass.php');\/* include file which you want to test*\/\nclass SampleClassTest extends PHPUnit_Framework_TestCase\n{\n    protected $dataarr1=array();\n   \/* PHPUnit supports sharing the setup code. \n      Before a test method is run, a template \n      method called setUp() is invoked. *\/\n    public function setUp(){\n      \/*setUp() is where you create the objects against which you will test. *\/\n       $this->dataarr1=array(5,6,7,8,9);\n    }\n   \/* Once the test method has finished running, \n      whether it succeeded or failed, another template \n      method called tearDown() is invoked. *\/\n    public function tearDown(){ \n    \/* tearDown() is where you clean up the objects against which you tested.  *\/\n       $this->dataarr1="";\n    }\n  \/* in below method we pass all element of $this->dataarr1 and counter $i value *\/\n    public function testMyObject(){\n        \/\/ test to ensure that the object from addNumber  is valid\n        $connObj=new SampleClass();\/* create object of class which you want to test *\/\n        for($i=1;$i<5;$i++){\n            \/*here value of $i is from 1 to 5 so it run successfully*\/\n           $this->assertTrue($connObj->divideNumber($this->dataarr1[$i],$i) !== false);\n\t}   \n   }\n  \n   public function testMyObjectnext(){\n        $connObj=new SampleClass();\n       for($i=0;$i<5;$i++){\n           \/*here value of $i is from 0 to 5 so it return error Division by zero  *\/\n           $this->assertTrue($connObj->divideNumber($this->dataarr1[$i],$i) !== false);\n       }  \n   }\n}\n?><\/pre>\n\n\n\n
For run test class<\/strong>
$ phpunit SampleClassTest.php<\/p>\n\n\n\n
output

test method “testMyObjec()” of class “SampleClassTest” executed successfully so in output we get period (.) that indicate successfully execution of test method.<\/p>\n\n\n\n
and for method “testMyObjectnext()” of class “SampleClassTest” execution we get “E” which indicate error occurs while running the test method. also we get detail about error in output.<\/p>\n","protected":false},"excerpt":{"rendered":"
