如何使用phpunit测试字符串

我正在创建这个字符串

'Your maximum heart rate is ' . $int . ' Your body mass index is ' . $float . ' Your body fat percentage is ' . $float '%.'

还它

我的主张是

$stringFormat = 'Your maximum heart rate is %d. Your body mass index is %f.  Your body fat percentage is %f%.';

        $this->assertStringMatchesFormat($stringFormat, $actualResultm, 'message');

当测试运行时，我得到了这个错误

FatControllerTest::testBodyInfo
message
Failed asserting that format description matches text.

-Your maximum heart rate is %d. Your body mass index is %f.  Your body fat percentage is %f%.
+Your maximum heart rate is 193. Your body mass index is 43.181818181818. Your body fat percentage is 6.32302%.

现在我想这一定与我告诉它期望一个无符号int和两个浮点有关，它返回一个长字符串，但如果是这样的话，我该如何测试我列出的字符串，它将有3个区域随情况而变化？如果不是这样，那我做错了什么？

我想你有两倍的空间

$stringFormat = 'Your maximum heart rate is %d. Your body mass index is %f.  Your body fat percentage is %f%.';
                                                                            ^ extra space

我想你有双重空间

$stringFormat = 'Your maximum heart rate is %d. Your body mass index is %f.  Your body fat percentage is %f%.';
                                                                            ^ extra space
