The setUp()
and tearDown()
methods are used in PHPUnit to set up and tear down the environment for each test case. Here's how to use them:
- Create a test class that extends the PHPUnitFrameworkTestCase class.

class MyTest extends PHPUnitFrameworkTestCase
{
// ...
}
|
- Declare a setUp() method in the test class. This method will be called before each test case.

class MyTest extends PHPUnitFrameworkTestCase
{
public function setUp(): void
{
// Set up the environment for each test case
}
}
|
- Declare a tearDown() method in the test class. This method will be called after each test case.

class MyTest extends PHPUnitFrameworkTestCase
{
public function tearDown(): void
{
// Clean up the environment after each test case
}
}

- Use the setUp() and tearDown() methods to prepare the environment and clean up any resources needed for each test case.

class MyTest extends PHPUnitFrameworkTestCase
{
public function setUp(): void
{
// Set up the environment for each test case
// e.g. initialize objects, connect to databases
}
public function tearDown(): void
{
// Clean up the environment after each test case
// e.g. close database connections, delete temporary files
}
public function testSomething(): void
{
// Test case code here
}
public function testAnotherThing(): void
{
// Test case code here
}
}

- PHPUnit will automatically call the setUp() method before each test case and the tearDown() method after each test case.
The setUp()
and tearDown()
methods ensure that each test case is executed in a clean environment, without any interference or dependencies from previous test cases.
