assertThat()

可以用 PHPUnit_Framework_Constraint 类来订立更加复杂的断言。这些断言可以用 assertThat() 方法对其进行评定。例 A.43展示了如何用 logicalNot()equalTo() 约束条件来表达与 assertNotEquals() 等价的断言。

assertThat(mixed $value, PHPUnit_Framework_Constraint $constraint[, $message = ''])

$value$constraint 不匹配时,报告一个错误,错误讯息的内容由 $message 指定。

assertTrue()

assertTrue(bool $condition[, string $message = ''])

$conditionFALSE时,报告一个错误,错误讯息的内容由 $message 指定。

assertNotTrue() 是此断言的逆断言,接受相同的参数。

例 A.44: assertTrue() 的用法

<?php
class TrueTest extends PHPUnit_Framework_TestCase
{
    public function testFailure()
    {
        $this->assertTrue(FALSE);
    }
}
?>

assertXmlFileEqualsXmlFile()

assertXmlFileEqualsXmlFile(string $expectedFile, string $actualFile[, string $message = ''])

$actualFile 中的 XML 文档与 $expectedFile 中的 XML 文档不相等时,报告一个错误,错误讯息的内容由 $message 指定。

assertXmlFileNotEqualsXmlFile() 是与之相反的断言,并接受相同的参数。

例 A.45: assertXmlFileEqualsXmlFile() 的用法

<?php
class XmlFileEqualsXmlFileTest extends PHPUnit_Framework_TestCase

    public function testFailure()
