PHPUnit provides various types of annotations that can be used to enhance and customize your test cases. Here are some common annotations and how to use them:
- @dataProvider: This annotation is used to provide data for parameterized tests. It can be used to run the same test method with different inputs and expected outputs.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
/**
* @dataProvider dataProviderFunction
*/
public function testMyFunction($input, $expectedOutput) {
// Test logic using input and assert against expected output
}
public function dataProviderFunction() {
return [
[1, 2],
[3, 6],
// Add more test cases with input and expected output
];
}
|
- @depends: This annotation is used to specify test dependencies. It allows you to specify that a test case depends on the successful completion of another test case.
1 2 3 4 5 6 7 8 9 10 11 12 13 |
public function testFirst() {
// Test logic
$this->assertTrue(true);
return 'some value';
}
/**
* @depends testFirst
*/
public function testSecond($valueFromFirstTest) {
// Test logic using the value returned from the first test
$this->assertEquals('some value', $valueFromFirstTest);
}
|
- @group: This annotation is used to group test cases. It allows you to specify a group name, and then you can run tests based on these groups.
1 2 3 4 5 6 7 8 9 10 11 12 13 |
/**
* @group mygroup
*/
public function testMyFunction() {
// Test logic
}
/**
* @group mygroup
*/
public function testAnotherFunction() {
// Test logic
}
|
To run tests based on groups, use the --group flag with the PHPUnit command. For example, vendor/bin/phpunit --group mygroup.
These are just a few examples of annotations in PHPUnit. For more information and other available annotations, refer to the PHPUnit documentation.
