assertNotContains()函數是PHPUnit中的內置函數,用於斷言沒有值的數組。如果數組不包含所提供的值,則該斷言將返回true;否則返回false;如果為true,則斷言了已通過測試的用例,否則測試用例失敗了。
用法:
assertNotContains(mixed $value, array $array, string $message = ''])
參數:該函數接受三個參數,如以上語法所示。參數說明如下:
- $value:此參數表示數組中不包含的值。
- $array:此參數是一個數組,assert函數將為其檢查其是否包含值。
- $message:此參數采用字符串值。當測試用例失敗時,此字符串消息將顯示為錯誤消息。
以下示例程序旨在說明assertNotContains()函數:
程序1::
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testNegativeTestcaseForAssertNotContains()
{
$testArray = array("a"=>"value ba", "b" =>"value b");
$value = "value ba";
// assert function to test whether 'value' is a value of array
$this->assertNotContains($value, $testArray, "testArray contains value as value") ;
}
}
?>
輸出:
PHPUnit 6.5.5 by Sebastian Bergmann and contributors. F 1 / 1 (100%) Time:21 ms, Memory:4.00MB There was 1 failure: 1) GeeksPhpunitTestCase::testNegativeTestcaseForAssertNotContains testArray contains value as value Failed asserting that an array does not contain 'value ba'. /home/shivam/Documents/geeks/phpunit/abc.php:11 FAILURES! Tests:1, Assertions:1, Failures:1.
程序2::
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testPositiveTestcaseForAssertNotContains()
{
$testArray = array("a"=>"value ba", "b" =>"value b");
$value = "value b";
// assert function to test whether 'value' is a value of array
$this->assertNotContains($value, $testArray, "testArray contains value as value") ;
}
}
?>
輸出:
PHPUnit 6.5.5 by Sebastian Bergmann and contributors. . 1 / 1 (100%) Time:21 ms, Memory:4.00MB OK (1 test, 1 assertion)
注意:要使用phpunit運行測試用例,請遵循此處的步驟。
