If you are testing the interaction between your PHP code and your MySQL database, you are performing integration testing, rather than unit testing.
Here are some examples of integration testing with Enhance PHP framework, it tests a repository class that saves and retrieves a Tenant object.
Instead of running against a pre-populated database, it runs on an entirely empty database and creates and destroys the tables as it goes using a simple table helper. This removes the dependency on particular data being in the right state in a test database, which is hard to keep in step.
<?php
class TenantRepositoryTestFixture extends EnhanceTestFixture {
private $Target;
public function SetUp() {
$tables = new TableHelper();
$tables->CreateTenantTable();
$this->Target = Enhance::GetCodeCoverageWrapper('TenantRepository');
}
public function TearDown() {
$tables = new TableHelper();
$tables->DropTenantTable();
}
public function SaveWithNewTenantExpectSavedTest() {
$tenant = new Tenant();
$tenant->Name = 'test';
$saved = $this->Target->Save($tenant);
$result = $this->Target->GetById($saved->Id);
Assert::AreNotIdentical(0, $result->Id);
Assert::AreIdentical($tenant->Name, $result->Name);
}
public function SaveWithExistingTenantExpectSavedTest() {
$tenant = new Tenant();
$tenant->Name = 'test';
$saved = $this->Target->Save($tenant);
$saved->Name = 'changed';
$saved = $this->Target->Save($saved);
$result = $this->Target->GetById($saved->Id);
Assert::AreIdentical($saved->Id, $result->Id);
Assert::AreIdentical($saved->Name, $result->Name);
}
}
?>
