To create an integration test that executes different logic in different store views, the Architect needs

to do the following steps:

Create one test class that extends \Magento\TestFramework\TestCase\AbstractController or

\Magento\TestFramework\TestCase\AbstractBackendController, depending on the type of controller

being tested1.

Create one test method that uses the @magentoDataFixture annotation to specify the data fixture

file that creates the product2.

Use the \Magento\TestFramework\Store\ExecuteInStoreContext class to execute the fixture and the

tested logic in different store views. This class has a method called executeInStoreContext, which

takes two parameters: the store ID and a callable function. The callable function will be executed in

the context of the given store ID, and then the original store ID will be restored3. For example:

PHPAI-generated code. Review and use carefully. More info on FAQ.

public function testSomeLogic()

{

// Get the product from the fixture

$product = $this->getProduct();

// Get the ExecuteInStoreContext instance from the object manager

$executeInStoreContext

=

$this->_objectManager-

>get(\Magento\TestFramework\Store\ExecuteInStoreContext::class);

// Execute the fixture in store view 3

$executeInStoreContext->executeInStoreContext(3, function () use ($product) {

// Do some operations on the product in store view 3

});

// Execute the tested logic in store view 4

$result = $executeInStoreContext->executeInStoreContext(4, function () use ($product) {

// Call the tested logic on the product in store view 4

return $this->someLogic->execute($product);

});

// Assert that the result is true

$this->assertTrue($result);

}
