simpleEnvironmentSetup()

The setup() static method of this class implements a simple set up of a service provider Prov in an existing testing environment:

static Prov* setup(TestEnv&);

If such a class is available for a given provider, the environment testing::TesterEnvironment offers the one-stop SimpleProviderSetup() method for the complete set up of that provider.

The setup() function will typically:

• find a suitable configuration for the service
• instantiate and set up the provider
• register the provider and possibly the interface it implements into the environment

The environment is expected to expose an interface equivalent to the one of testing::TesterEnvironment.

See SimpleEnvironmentStandardSetupClass for a class suitable as base class for your own implementation.

To implement a setup for MyProvider, the specialisation can follow the pattern:

template <typename TestEnv>
struct SimpleEnvironmentSetupClass<MyProvider, TestEnv> {

  static MyProvider* setup(TestEnv& env)
    {
      // create and set up the provider, e.g.
      auto prov = std::make_unique<MyProvider>(
        // constructor arguments...
        );
      // yield and register the provider to the environment
      MyProvider* prov_ptr = env.AcquireProvider<MyProvider>(prov);
      return prov_ptr;
    } // setup()

}; // SimpleEnvironmentSetupClass<MyProvider>

Note that the class must be fully constructed by the default constructor, in order for it to work with the tester environment.
