assertStringEndsWith()函数是PHPUnit中的内置函数,用于断言实际字符串是否以预期的后缀字符串结尾。如果预期的后缀字符串以实际字符串结尾,则此断言将返回true,否则返回false。如果为真,则通过断言的测试用例,否则测试用例失败。
用法:
assertStringEndsWith(string $suffix, string $string [, string $message = ''])
参数:该函数接受三个参数,如上面的语法所示。参数说明如下:
- $expectedsuffix:此参数可以是代表期望的后缀字符串的任何类型。
- $actualstring:此参数可以是代表实际字符串的任何类型。
- $message:此参数采用字符串值。当测试用例失败时,此字符串消息将显示为错误消息。
以下示例说明了PHPUnit中的assertStringEndsWith()函数:
范例1:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testNegativeTestcaseForassertStringEndsWith()
{
$expectedsuffix = ('thh');
$actualstring = ('4th');
// Assert function to test whether
// expected suffix string ends with
// actual string content
$this->assertStringEndsWith(
$expectedsuffix,
$actualstring,
"actual string content ends with expected
suffix content"
);
}
}
?>
输出:
PHPUnit 8.5.8 by Sebastian Bergmann and contributors. F 1 / 1 (100%) Time:90 ms, Memory:10.00 MB There was 1 failure: 1) GeeksPhpunitTestCase::testPositiveTestcaseForassertStringNotEqualsFile actual string content ends with expected suffix content Failed asserting that '4th' ends with "thh". /home/lovely/Documents/php/test.php:17 FAILURES! Tests:1, Assertions:1, Failures:1.
范例2:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testPositiveTestcaseForassertStringEndsWith()
{
$expectedsuffix = ('th');
$actualstring = ('4th');
// Assert function to test whether
// expected suffix
// string ends with actual string content
$this->assertStringEndsWith(
$expectedsuffix,
$actualstring,
"actual string content ends with
expected suffix content"
);
}
}
?>
输出:
PHPUnit 8.5.8 by Sebastian Bergmann and contributors. . 1 / 1 (100%) Time:88 ms, Memory:10.00 MB OK (1 test, 1 assertion)
