Typedef Documentation

template<typename Prov , typename... Args>

using testing::setupProvider_t = typedef std::function<std::unique_ptr<Prov>(Args...)>

Generic setup provider function type.

Definition at line 34 of file ProviderTestHelpers.h.

using testing::StandardStopWatch = typedef StopWatch<>

A StopWatch with default template arguments.

Definition at line 166 of file StopWatch.h.

Function Documentation

template<typename CONFIG , typename TESTENV = TesterEnvironment<std::decay_t<CONFIG>>, typename... ARGS>

TESTENV testing::CreateTesterEnvironment	(	CONFIG &&	config,
		ARGS...	other_args
	)

Constructs and returns a TesterEnvironment object.

Template Parameters

CONFIG	type of configuration object (detected from arguments)
TESTENV	type of the tester environment (default: TesterEnvironment)
ARGS	pack of types of the remining constructor arguments (optional)

Parameters

config	the configuration object to be used
other_args	the remaining arguments of the tester constructor

This function creates and returns a tester environment. By default, the tester environment class is TesterEnvironment<CONFIG> and no additional constructor arguments are needed except for special needs. The simplest way to use the function with an already available configuration is:

auto TestEnv = testing::CreateTesterEnvironment(config);

where TestEnv is assigned a specialization of TesterEnvironment.

The template class TESTENV undergoes the following requirement:

it must have a constructor using a CONFIG constant reference as first argument

The CONFIG object is subject to no special requirements besides the ones from TESTENV constructor.

Definition at line 998 of file unit_test_base.h.

   {
     return TESTENV(std::forward<CONFIG>(config), std::forward<ARGS>(other_args)...);
   }

template<typename Prov , typename... Args>

std::unique_ptr<Prov> testing::setupProvider ( Args &&... args )

Function calling ProviderSetupClass<>::setup for the specified provider.

Template Parameters

Prov	type of the provider to be created and set up
Args	types of arguments to the setup function

Parameters

args	arguments to the setup function

Returns: a pointer to the newly created and set up provider

See also: ProviderSetup

This function provides a function-like interface to the ProviderSetup classes. An example of its use to create an instance of MyProvider is:

auto prov = testing::setupProvider<MyProv>
  (pset.get<fhicl::ParameterSet>("services.MyProviderService"));

if MyProvider provider has a constructor taking a fhicl::ParameterSet.

Definition at line 95 of file ProviderTestHelpers.h.

   {
     return ProviderSetupClass<Prov>::setup(std::forward<Args>(args)...);
   }

template<typename Prov , typename TestEnv >

Prov* testing::simpleEnvironmentSetup ( TestEnv & env )

Sets up a provider in a specified test environment.

Template Parameters

Prov	type of the provider to be set up
TestEnv	type of the environment

Parameters

env	the environment to be set up

Returns: a pointer to the newly set up provider

See also: SimpleEnvironmentSetupClass

This function performs the over-simple set up of a provider. The set up is completely delegated to a SimpleEnvironmentSetupClass class. No such class is provided by default, and service implementers must write their own to allow this one to work.

Definition at line 227 of file ProviderTestHelpers.h.

   {
     return SimpleEnvironmentSetupClass<Prov, TestEnv>::setup(env);
   }

template<typename Prov , typename Interface , typename TestEnv >

Prov* testing::SimpleEnvironmentStandardSetupByName	(	TestEnv &	env,
		std::string	service_name
	)

inline

Basic implementation of a environment setup helper.

Template Parameters

Prov	type of provider being set up
TestEnv	type of environment to set up
Interface	(optional) type of interface being implemented

See also: SimpleEnvironmentSetupClass()

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

The setup() function:

finds a suitable configuration for the service from the environment
instantiates and sets up the provider
registers the provider and the interface it implements into the environment

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

template <typename TestEnv>
struct SimpleEnvironmentSetupClass<MyProv, TestEnv>
  : public SimpleEnvironmentStandardSetupClass<MyProv, TestEnv, MyInterface>
{
  SimpleEnvironmentSetupClass():
    SimpleEnvironmentStandardSetupClass<MyProvider, TestEnv, MyInterface>("MyService")
    {}
};

to register a provider of type MyProvider that implements a provider interface MyInterface, reading its configuration from the service configuration of "MyService" (that is, services.MyService).

The environment is then expected to react to both MyProvider and MyInterface types:

env.Provider<MyProvider>();
env.Provider<MyInterface>();

both return a pointer to the same provider. If instead MyInterface is void (default), no interface is registered.

Note: This class itself is not suitable for direct use in the test environment, lacking a default constructor. The setup class can inherit from it, as in the example above.
