Question

当尝试使用phpdbg运行感染测试时，我不断收到内存耗尽错误。我尝试设置-d memory_limit，但似乎被忽略了。

下面是一些示例输出：

$ phpdbg -qrr -d memory_limit=1G vendor/bin/infection
You are running Infection with phpdbg enabled.
     ____      ____          __  _
    /  _/___  / __/__  _____/ /_(_)___  ____
    / // __ \/ /_/ _ \/ ___/ __/ / __ \/ __ \
  _/ // / / / __/  __/ /__/ /_/ / /_/ / / / /
 /___/_/ /_/_/  \___/\___/\__/_/\____/_/ /_/

Running initial test suite...

PHPUnit version: 7.5.11

    4 [============================]  1 sec

 [ERROR] Project tests must be in a passing state before running Infection.

         Infection runs the test suite in a RANDOM order. Make sure your tests do not have hidden dependencies.

         You can add these attributes to `phpunit.xml` to check it: <phpunit executionOrder="random"
         resolveDependencies="true" ...

         If you don't want to let Infection run tests in a random order, set the `executionOrder` to some value, for
         example <phpunit executionOrder="default"

         Check the executed command to identify the problem: '/usr/local/Cellar/php@7.2/7.2.18/bin/phpdbg' '-qrr'
         '~/Project/vendor/phpunit/phpunit/phpunit' '--configuration'
         '/var/folders/05/qbcbz9cn08jdty7r35dwkgdm0000gn/T/infection/phpunitConfiguration.initial.infection.xml'

         PHPUnit reported an exit code of 255.

         Refer to the PHPUnit's output below:

         STDOUT:

带有我的fection.json.dist文件：

{
    "timeout": 10,
    "source": {
        "directories": [
            "src"
        ]
    },
    "logs": {
        "text": "infection.log"
    },
    "mutators": {
        "@default": true
    }
}

Answer 1

您要在开发环境的memory_limit=-1配置文件中使用php.ini。

Answer 2

您可以事先收集承保范围，然后将其提供给感染。

vendor/bin/phpunit --coverage-xml=build/logs/coverage-xml \
                   --log-junit=build/logs/phpunit.junit.xml \
                   --coverage-clover=build/logs/clover.xml
vendor/bin/infection --coverage=build/logs --show-mutations

由于您不会同时运行Infection和PHPUnit，因此可以完全避免内存限制问题。如果没有，那么运行具有更高内存限制的任何程序都应该像以下操作一样简单：

php -d memory_limit=-1 vendor/bin/...

这样，您还可以在修复测试后重新运行感染，以查看是否杀死了一个突变而无需重新收集覆盖率数据。
