PHPUnit equalTo on dates with Delta.
PHPUnit equalTo on dates with Delta.
提问于 2011-08-17 18:35:38
我在PHPUnit中遇到了一个问题，在比较日期时，我想在equalTo方法中使用增量参数。比方说，如果日期相差不超过10秒，我想将它们视为相等。$some_delta的合适值是多少? 10? 10000？或者是完全不同的东西？
$this->_restClient->expects($this->at(0))
->method('getData')
->with(
$this->equalTo(array('1')),
$this->equalTo(array('2')),
$this->equalTo($this->_date, $some_delta),
$this->equalTo(null),
)
->will($this->returnValue($this->_restResponses['generalRestResponse']));回答 3

PHPUnit >= 7.5 (DateTime)
class MyDatesTest extends PHPUnit_Framework_TestCase {
public function testAllDateOk() {
$date1 = new DateTime('2019-01-01 00:00:00');
$date2 = new DateTime('2019-01-01 00:00:03');
// ± 5 seconds are equals
$this->assertEqualsWithDelta($date1->getTimestamp(), $date2->getTimestamp(), 5);
// ± 1 second are distinct
$this->assertNotEqualsWithDelta($date1->getTimestamp(), $date2->getTimestamp(), 1);
}
}PHPUnit >= 7.5 (碳)
class MyDatesTest extends PHPUnit_Framework_TestCase {
public function testAllDateOk() {
$date1 = Carbon::now();
$date2 = Carbon::now()->addSeconds(3);
// ± 5 seconds are equals
$this->assertEqualsWithDelta($date1->timestamp, $date2->timestamp, 5);
// ± 1 second are distinct
$this->assertNotEqualsWithDelta($date1->timestamp, $date2->timestamp, 1);
}
}说明:从PHPUnit 8开始，不推荐使用带有4个参数的assertEquals

增量值只需为秒数
您需要时间戳可以与4th parameter to assert equals或2nd to equalTo不同的秒数。这两个函数( assertEquals / equalTo )都指向PHPUnit_Framework_Constraint_IsEqual，因此增量处理是相同的。
示例：
<?php
class foo extends PHPUnit_Framework_TestCase {
public function testDateDiffsWorks() {
$date1 = new DateTime('2011-01-01 00:00:00');
$date2 = new DateTime('2011-01-01 00:00:03');
$this->assertEquals($date1->getTimestamp(), $date2->getTimestamp(), '', 5);
}
public function testDateDiffsFails() {
$date1 = new DateTime('2011-01-01 00:00:00');
$date2 = new DateTime('2011-01-01 00:00:03');
$this->assertEquals($date1->getTimestamp(), $date2->getTimestamp(), '', 0.5);
}
}和输出
第一个测试有效，第二个测试失败。

对edorian答案的补充-从PhpUnit v7.5开始，您可以使用assertEqualsWithDelta()，自PhpUnit v8以来，就不再推荐使用assertEquals()
