Chapter 3. The Command-Line Test Runner

The PHPUnit command-line test runner can be invoked through the phpunit command. The following code shows how to run tests with the PHPUnit command-line test runner:

phpunit ArrayTest
PHPUnit 4.1.0 by Sebastian Bergmann.

..

Time: 0 seconds


OK (2 tests, 2 assertions)

When invoked as shown above, the PHPUnit command-line test runner will look for a ArrayTest.php sourcefile in the current working directory, load it, and expect to find a ArrayTest test case class. It will then execute the tests of that class.

For each test run, the PHPUnit command-line tool prints one character to indicate progress:

.

Printed when the test succeeds.

F

Printed when an assertion fails while running the test method.

E

Printed when an error occurs while running the test method.

R

Printed when the test has been marked as risky (see Chapter 6).

S

Printed when the test has been skipped (see Chapter 7).

I

Printed when the test is marked as being incomplete or not yet implemented (see Chapter 7).

PHPUnit distinguishes between failures and errors. A failure is a violated PHPUnit assertion such as a failing assertEquals() call. An error is an unexpected exception or a PHP error. Sometimes this distinction proves useful since errors tend to be easier to fix than failures. If you have a big list of problems, it is best to tackle the errors first and see if you have any failures left when they are all fixed.

phpunit UnitTest

Runs the tests that are provided by the class UnitTest. This class is expected to be declared in the UnitTest.php sourcefile.

UnitTest must be either a class that inherits from PHPUnit_Framework_TestCase or a class that provides a public static suite() method which returns an PHPUnit_Framework_Test object, for example an instance of the PHPUnit_Framework_TestSuite class.

phpunit UnitTest UnitTest.php

Runs the tests that are provided by the class UnitTest. This class is expected to be declared in the specified sourcefile.

--coverage-clover

Generates a logfile in XML format with the code coverage information for the tests run. See Chapter 14 for more details.

Please note that this functionality is only available when the tokenizer and Xdebug extensions are installed.

--coverage-crap4j

Generates a code coverage report in Crap4j format. See Chapter 11 for more details.

Please note that this functionality is only available when the tokenizer and Xdebug extensions are installed.

--coverage-html

Generates a code coverage report in HTML format. See Chapter 11 for more details.

Please note that this functionality is only available when the tokenizer and Xdebug extensions are installed.

--coverage-php

Generates a serialized PHP_CodeCoverage object with the code coverage information.

Please note that this functionality is only available when the tokenizer and Xdebug extensions are installed.

--coverage-text

Generates a logfile or command-line output in human readable format with the code coverage information for the tests run. See Chapter 14 for more details.

Please note that this functionality is only available when the tokenizer and Xdebug extensions are installed.

--log-junit

Generates a logfile in JUnit XML format for the tests run. See Chapter 14 for more details.

--log-tap

Generates a logfile using the Test Anything Protocol (TAP) format for the tests run. See Chapter 14 for more details.

--log-json

Generates a logfile using the JSON format. See Chapter 14 for more details.

--testdox-html and --testdox-text

Generates agile documentation in HTML or plain text format for the tests that are run. See Chapter 12 for more details.

--filter

Only runs tests whose name matches the given regular expression pattern. If the pattern is not enclosed in delimiters, PHPUnit will enclose the pattern in / delimiters.

The test names to match will be in one of the following formats:

TestNamespace\TestCaseClass::testMethod

The default test name format is the equivalent of using the __METHOD__ magic constant inside the test method.

TestNamespace\TestCaseClass::testMethod with data set #0

When a test has a data provider, each iteration of the data gets the current index appended to the end of the default test name.

TestNamespace\TestCaseClass::testMethod with data set "my named data"

When a test has a data provider that uses named sets, each iteration of the data gets the current name appended to the end of the default test name. See Example 3.1 for an example of named data sets.

Example 3.1: Named data sets

<?php
namespace TestNamespace;

class TestCaseClass extends \PHPUnit_Framework_TestCase
{
    /**
     * @dataProvider provider
     */
    public function testMethod($data)
    {
        $this->assertTrue($data);
    }

    public function provider()
    {
        return array(
           'my named data' => array(true),
           'my data'       => array(true)
        );
    }
}
?>


/path/to/my/test.phpt

The test name for a PHPT test is the filesystem path.

See Example 3.2 for examples of valid filter patterns.

Example 3.2: Filter pattern examples

  • --filter 'TestNamespace\\TestCaseClass::testMethod'

  • --filter 'TestNamespace\\TestCaseClass'

  • --filter TestNamespace

  • --filter TestCaseClass

  • --filter testMethod

  • --filter '/::testMethod .*"my named data"/'

  • --filter '/::testMethod .*#5$/'

  • --filter '/::testMethod .*#(5|6|7)$/'



See Example 3.3 for some additional shortcuts that are available for matching data providers.

Example 3.3: Filter shortcuts

  • --filter 'testMethod#2'

  • --filter 'testMethod#2-4'

  • --filter '#2'

  • --filter '#2-4'

  • --filter 'testMethod@my named data'

  • --filter 'testMethod@my.*data'

  • --filter '@my named data'

  • --filter '@my.*data'



--testsuite

Only runs the test suite whose name matches the given pattern.

--group

Only runs tests from the specified group(s). A test can be tagged as belonging to a group using the @group annotation.

The @author annotation is an alias for @group allowing to filter tests based on their authors.

--exclude-group

Exclude tests from the specified group(s). A test can be tagged as belonging to a group using the @group annotation.

--list-groups

List available test groups.

--test-suffix

Only search for test files with specified suffix(es).

--report-useless-tests

Be strict about tests that do not test anything. See Chapter 6 for details.

--strict-coverage

Be strict about unintentionally covered code. See Chapter 6 for details.

--disallow-test-output

Be strict about output during tests. See Chapter 6 for details.

--enforce-time-limit

Enforce time limit based on test size. See Chapter 6 for details.

--strict

Run tests in strict mode (same as using --report-useless-tests, --strict-coverage, --disallow-test-output, and --enforce-time-limit). See Chapter 6 for details.

--process-isolation

Run each test in a separate PHP process.

--no-globals-backup

Do not backup and restore $GLOBALS. See the section called “Global State” for more details.

--static-backup

Backup and restore static attributes of user-defined classes. See the section called “Global State” for more details.

--colors

Use colors in output. On Windows, use ANSICON or ConEmu.

--stderr

Optionally print to STDERR instead of STDOUT.

--stop-on-error

Stop execution upon first error.

--stop-on-failure

Stop execution upon first error or failure.

--verbose

Output more verbose information, for instance the names of tests that were incomplete or have been skipped.

--debug

Output debug information such as the name of a test when its execution starts.

--loader

Specifies the PHPUnit_Runner_TestSuiteLoader implementation to use.

The standard test suite loader will look for the sourcefile in the current working directory and in each directory that is specified in PHP's include_path configuration directive. A class name such as Project_Package_Class is mapped to the source filename Project/Package/Class.php.

--repeat

Repeatedly runs the test(s) the specified number of times.

--tap

Reports the test progress using the Test Anything Protocol (TAP). See Chapter 14 for more details.

--testdox

Reports the test progress as agile documentation. See Chapter 12 for more details.

--printer

Specifies the result printer to use. The printer class must extend PHPUnit_Util_Printer and implement the PHPUnit_Framework_TestListener interface.

--bootstrap

A "bootstrap" PHP file that is run before the tests.

--configuration, -c

Read configuration from XML file. See Appendix C for more details.

If phpunit.xml or phpunit.xml.dist (in that order) exist in the current working directory and --configuration is not used, the configuration will be automatically read from that file.

--no-configuration

Ignore phpunit.xml and phpunit.xml.dist from the current working directory.

--include-path

Prepend PHP's include_path with given path(s).

-d

Sets the value of the given PHP configuration option.

Note

Please note that options must not be put after the argument(s).
