默认情况下在PHPUnit中运行单个测试套件

Question

My PHPUnit configuration file has two test suites, unit and system. When I run the test runner vendor/bin/phpunit, it runs all tests in both suites. I can target a single suite with the testsuite flag: vendor/bin/phpunit --testsuite unit, but I need to configure the test runner to run only the unit suite by default, and to run integration only when specifically called with the testsuite flag.

My configuration:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit colors="true">
  <testsuites>
    <testsuite name="unit">
      <directory>tests/Unit</directory>
    </testsuite>
    <testsuite name="integration">
      <directory>tests/Integration</directory>
    </testsuite>
  </testsuites>
  <filter>
    <whitelist>
      <directory suffix=".php">src</directory>
    </whitelist>
  </filter>
  <logging>
    <log type="coverage-clover" target="build/clover.xml"/>
  </logging>
</phpunit>

There doesn't appear to be a way to list multiple testsuites from a phpunit.xml file, but then only run one. However, if you do have some control over a fuller integration and testing environment where you can configure things more exactly, you can have more than one phpunit configuration files, and set one (or more) with more involved environments to set the command-line parameter --configuration <file> option with a configuration that will do more. This at least makes sure that the simplest config will run in the easiest fashion.

The two files can be called whatever you like if you run them specifically, but it may be worth thinking about having the quick-to-run file called the default phpunit.xml, and the specifically named and extended filem as phpunit.xml.dist. The .dist file will be automatically run by default if the original plain .xml does not exist. Another option is to have the phpunit.xml.dist file in a code repository, but then copy it to a phpunit.xml file, with less testsuite's, which is not in itself checked into version control, and is only kept locally (it would probably also be marked as ignored in a .gitignore file, or similar).
