我在 CakePHP 中遇到了几个我想提交修复的问题，但我想确保我所做的任何更改都通过了单元测试。问题是单元测试对我来说不太适合开箱即用的代码！我确信单元测试本身很好，并且对其他人来说也很好，所以这可能是我的环境中的某些东西导致了问题。
我在 PHP 版本 5.6.19 上运行 CakePHP 版本 3.2.5。我的 PHP 构建配置（包括在内，因为我必须重建它几次才能让它运行这么多的测试，所以理论上这可能是问题所在）：
'./configure' '--enable-fileinfo' '--enable-phar' '--disable-maintainer-zts' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--enable-gd-native-ttf' '--enable-libxml' '--enable-mbstring' '--enable-pdo=shared' '--enable-sockets' '--with-apxs2=/usr/sbin/apxs' '--with-curl' '--with-freetype-dir=/usr' '--with-gd' '--with-jpeg-dir=/usr' '--with-kerberos' '--with-libdir=lib64' '--with-mssql=/usr' '--with-mysql=/usr' '--with-mysqli=/usr/bin/mysql_config' '--with-pcre-regex' '--with-pdo-mysql=shared' '--without-sqlite' '--with-sqlite3=shared' '--with-pdo-sqlite=shared,/usr' '--with-pic' '--with-png-dir=/usr' '--with-zlib' '--with-zlib-dir=/usr' '--with-openssl' '--enable-intl'
可能还有 php.ini 设置会影响其中的一些？
用于为测试设置 CakePHP 的命令
$ git clone git@github.com:cakephp/cakephp.git
$ cd cakephp
第一次尝试
$ make test

make: *** [test] Error 255
这是因为它试图使用 fr_FR 语言环境解析“13 10, 2015”，但这似乎无效。我通过在第 169 行和第 185 行将字符串更改为“13/10/2015”来修复它。（我还添加了assertNotNull调用。）

我没有完全跟踪这个，只是让它失败并通过添加$this->assertNotNull($result);.
第三次尝试
$ make test
