PhpUnit和字符串(PhpUnit and string)

PhpUnit和字符串(PhpUnit and string)

我开始学习PhpUnit和测试。 我有一个返回字符串的方法，我怎么能写一个测试来检查这个方法是否返回字符串。 这是我目前的代码：

方法：

/** * @return string */ public function living() { return 'Happy!'; }

测试：

public $real; public $expected; public function testLiving() { $this->expected = 'Happy'; $this->real = 'Speechless'; $this->assertTrue($this->expected == $this->real); }

I started learning PhpUnit and testing. I have a method which returns string, how I can write a test to check if this method returns string. Here is the code I have at this moment:

Method:

/** * @return string */ public function living() { return 'Happy!'; }

Test:

public $real; public $expected; public function testLiving() { $this->expected = 'Happy'; $this->real = 'Speechless'; $this->assertTrue($this->expected == $this->real); }

最满意答案

$this->assertTrue($this->expected == $this->real);

是相同的

$this->assertEquals($this->expected, $this->real);

请参阅https://phpunit.de/manual/current/en/appendixes.assertions.html#appendixes.assertions.assertEquals

两者都检查给定的变量是否相等。

你可以检查变量是否是字符串

$this->assertTrue(is_string($this->real)); $this->assertTrue($this->expected == $this->real);

is the same as

$this->assertEquals($this->expected, $this->real);

See https://phpunit.de/manual/current/en/appendixes.assertions.html#appendixes.assertions.assertEquals

Both check if given variables are equal.

You could check if variable is string

$this->assertTrue(is_string($this->real));
