@requires The @requires annotation can be used to skip tests when common preconditions, like the PHP Version or installed extensions, are not met. A complete list of possibilities and examples can be found at Table 7.3

PHPUnit The attributes of the <phpunit> element can be used to configure PHPUnit's core functionality. <phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/4.5/phpunit.xsd" backupGlobals="true" backupStaticAttributes="false" <!--bootstrap="/path/to/bootstrap.php"--> cacheTokens="false" colors="false" convertErrorsToExceptions="true"

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 5.6.0 by Sebastian Bergmann and contributors. .. 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 th

@beforeClass The @beforeClass annotation can be used to specify static methods that should be called before any test methods in a test class are run to set up shared fixtures. use PHPUnit\Framework\TestCase; class MyTest extends TestCase { /** * @beforeClass */ public static function setUpSomeSharedFixtures() { // ... } /** * @beforeClass */ public static function setUpSomeOtherSharedFixtures() { // ... } }

assertJsonStringEqualsJsonFile() assertJsonStringEqualsJsonFile(mixed $expectedFile, mixed $actualJson[, string $message = '']) Reports an error identified by $message if the value of $actualJson does not match the value of $expectedFile. Example A.34: Usage of assertJsonStringEqualsJsonFile() <?php use PHPUnit\Framework\TestCase; class JsonStringEqualsJsonFileTest extends TestCase { public function testFailure() { $this->assertJsonStringEqualsJsonFile( 'p

assertArrayHasKey() assertArrayHasKey(mixed $key, array $array[, string $message = '']) Reports an error identified by $message if $array does not have the $key. assertArrayNotHasKey() is the inverse of this assertion and takes the same arguments. Example A.1: Usage of assertArrayHasKey() <?php use PHPUnit\Framework\TestCase; class ArrayHasKeyTest extends TestCase { public function testFailure() { $this->assertArrayHasKey('foo', ['bar' => 'baz']); } } ?> phpun

assertNan() assertNan(mixed $variable[, string $message = '']) Reports an error identified by $message if $variable is not NAN. Example A.38: Usage of assertNan() <?php use PHPUnit\Framework\TestCase; class NanTest extends TestCase { public function testFailure() { $this->assertNan(1); } } ?> phpunit NanTest PHPUnit 5.6.0 by Sebastian Bergmann and contributors. F Time: 0 seconds, Memory: 5.00Mb There was 1 failure: 1) NanTest::testFailure Failed asserting tha

In computer science, code coverage is a measure used to describe the degree to which the source code of a program is tested by a particular test suite. A program with high code coverage has been more thoroughly tested and has a lower chance of containing software bugs than a program with low code coverage. --Wikipedia In this chapter you will learn all about PHPUnit's code coverage functionality that provides an insight into what parts of the production code are executed when the t

PHPUnit can be extended in various ways to make the writing of tests easier and customize the feedback you get from running tests. Here are common starting points to extend PHPUnit. Subclass PHPUnit\Framework\TestCase Write custom assertions and utility methods in an abstract subclass of PHPUnit\Framework\TestCase and derive your test case classes from that class. This is one of the easiest ways to extend PHPUnit. Write custom assertions When writing custom assertions it is the best pract

assertFileExists() assertFileExists(string $filename[, string $message = '']) Reports an error identified by $message if the file specified by $filename does not exist. assertFileNotExists() is the inverse of this assertion and takes the same arguments. Example A.23: Usage of assertFileExists() <?php use PHPUnit\Framework\TestCase; class FileExistsTest extends TestCase { public function testFailure() { $this->assertFileExists('/path/to/file'); } } ?> phpunit File
