PHPUnit9.0 斷言-assertEqualsCanonicalizing()

assertEqualsCanonicalizing(mixed $expected, mixed $actual[, string $message = '' ])

PHPUnit9.0 斷言集合

當(dāng)兩個(gè)變量 ?$expected? 和 ?$actual? 不相等時(shí)報(bào)告錯(cuò)誤，錯(cuò)誤訊息由 ?$message? 指定。
先對(duì) ?$expected? 和 ?$actual? 進(jìn)行規(guī)范化，然后再進(jìn)行比較。例如，如果兩個(gè)變量 ?$expected? 和 ?$actual? 是數(shù)組，則會(huì)先對(duì)這些數(shù)組進(jìn)行排序然后再進(jìn)行比較。當(dāng) ?$expected? 和 ?$actual? 是對(duì)象時(shí)，則每個(gè)對(duì)象都會(huì)被轉(zhuǎn)換為一個(gè)包含所有私有、保護(hù)、和公開屬性的數(shù)組。
?assertNotEqualsCanonicalizing()? 是與之相反的斷言，接受相同的參數(shù)。
