assertIsBool()函数是PHPUnit中的内置函数,用于断言实际获得的值是否为Bool。如果实际值为Bool,则此断言将返回true,否则Bool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:
assertIsBool($actual[, $message = ''])
参数:此函数接受上述和以下描述的两个参数:
- $actualvalue:此参数可以是代表实际数据的任何类型。
- $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assertIsBool()函数:
范例1:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testNegativeForassertIsNotBooltrue()
{ $actual = 420;
// Assert function to test whether actual
// value is (true or false) or not
$this->assertIsBool(
$actual,
"actual value is Bool or not"
);
}
public function testNegativeForassertIsNotBoolFalse()
{
$actual = 220;
// Assert function to test whether actual
// value is (true or false) or not
$this->assertIsBool(
$actual,
"actual value is Bool or not"
);
}
}
?>

范例2:
PHP
<?php
use PHPUnit\Framework\TestCase;
class GeeksPhpunitTestCase extends TestCase
{
public function testPositiveForassertIsNotBooltrue()
{ $actual = true;
// Assert function to test whether actual
// value is (true or false) or not
$this->assertIsBool(
$actual,
"actual value is Bool or not"
);
}
public function testPositiveForassertIsNotBoolFalse()
{
$actual = false;
// Assert function to test whether actual
// value is (true or false) or not
$this->assertIsBool(
$actual,
"actual value is Bool or not"
);
}
}
?>
输出:
