PHPUnit (1) 安裝

Installation

For a system-wide installation via Composer, you can run:

$ composer global require "phpunit/phpunit=5.5.*"

In MacOS Sierra, you might need to use sudo for permission issue.

After installation, you can check PHPUnit version by:

$ phpunit --version
PHPUnit 5.5.7 by Sebastian Bergmann and contributors.

If it shows up command not found, try:

$ ~/.composer/vendor/bin/phpunit --version
PHPUnit 5.5.7 by Sebastian Bergmann and contributors.

# Then you can use alias for short
$ alias phpunit='~/.composer/vendor/bin/phpunit'
$ phpunit --version
PHPUnit 5.5.7 by Sebastian Bergmann and contributors.

Test PHPUnit

After installation of PHPUnit, let's try use it.

Create TestClass.php

1. Make a new class TestSample
2. TestSample inherits from PHPUnit\Framework\TestCase.
3. Call method assertEquals for this test.

<?php
use PHPUnit\Framework\TestCase;

class TestSample extends TestCase{

  function testSample1()  {
  
    // assertEquals($a, $b) checks if $a == $b.
    $this->assertEquals(2, 1+1);
  }
  
  function testSample2()  {
  
    $this->assertEquals(2, 1-1);
  }
}

Running Test

Save php file, in terminal we can run it by command. Option --color can make syntax highlighting.

$ phpunit --color TestSample.php
PHPUnit 4.7.3 by Sebastian Bergmann and contributors.
