UnitTest

Unit test library on top of PHP Unit.

Installation

Note: PHP 7.1 or higher is required.

1. Install composer.
2. Run composer require fabstract/unit-test.

Usage

MethodTestBase

This class is used for separating unit tests by which methods they were written for. Suppose you have the following class:

    
    namespace MyPackage;
    
    class Calculator
    {
        public function add($a, $b) {
            return $a + $b;
        }
        
        public function multiply($a, $b) {
            return $a * $b;
        }
    }

Now in order to write tests for these two methods:

• Create a directory, preferably the same name with the class name.
• Inside that directory, create a class for each method you want to test.
• Name the class as methodName + MethodTest. For example AddMethodTest.
• Extend the class from MethodTestBase.

Note: Your method should be camelcase.

Here is what it looks like:

    namespace MyPackage\Calculator;

    class AddMethodTest extends \Fabstract\Component\UnitTest\MethodTestBase
    {
        public function testOneAndOneEqualsTwo() {
            $arguments = [1, 1];
            
            $result = $this->call(new Calculator(), $arguments);
            
            $this->assertEquals(2, $result);
        }
        
        public function testOneAndZeroEqualsOne() {
            $arguments = [1, 0];
            
            $result = $this->call(new Calculator(), $arguments);
            
            $this->assertEquals(1, $result);
        }
    }

and

    namespace MyPackage\Calculator;

    class MultiplyMethodTest extends \Fabstract\Component\UnitTest\MethodTestBase
    {
        public function testOneAndOneEqualsOne() {
            $arguments = [1, 1];
            
            $result = $this->call(new Calculator(), $arguments);
            
            $this->assertEquals(1, $result);
        }
        
        public function testOneAndZeroEqualsZero() {
            $arguments = [1, 0];
            
            $result = $this->call(new Calculator(), $arguments);
            
            $this->assertEquals(0, $result);
        }
    }

You can add as many unit tests as you want, without worrying about a method's tests getting mixed up with other method's tests.
