			// Value-parameterized tests allow you to test your code with different
			// parameters without writing multiple copies of the same test.
			//
			// Here is how you use value-parameterized tests:

			#if 0

			// To write value-parameterized tests, first you should define a fixture
			// class. It is usually derived from testing::TestWithParam<T> (see below for
			// another inheritance scheme that's sometimes useful in more complicated
			// class hierarchies), where the type of your parameter values.
			// TestWithParam<T> is itself derived from testing::Test. T can be any
			// copyable type. If it's a raw pointer, you are responsible for managing the
			// lifespan of the pointed values.

			class FooTest : public ::testing::TestWithParam<const char*> {
			// You can implement all the usual class fixture members here.
			};

			// Then, use the TEST_P macro to define as many parameterized tests
			// for this fixture as you want. The _P suffix is for "parameterized"
			// or "pattern", whichever you prefer to think. The arguments to the
			// TEST_P macro are the test_suite_name and test_case (both which must be
			// non-empty) that will form the test name.

			TEST_P(FooTest, DoesBlah) {
			// Inside a test, access the test parameter with the GetParam() method
			// of the TestWithParam<T> class:
			EXPECT_TRUE(foo.Blah(GetParam()));
			...
			}

			TEST_P(FooTest, HasBlahBlah) {
			...
			}

			// Finally, you can use INSTANTIATE_TEST_SUITE_P to instantiate the test
			// case with any set of parameters you want. Google Test defines a number
			// of functions for generating test parameters. They return what we call
			// (surprise!) parameter generators. Here is a summary of them, which
			// are all in the testing namespace:
			//
			//
			// Range(begin, end [, step]) - Yields values {begin, begin+step,
			// begin+step+step, ...}. The values do not
			// include end. step defaults to 1.
			// Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}.
			// ValuesIn(container) - Yields values from a C-style array, an STL
			// ValuesIn(begin,end) container, or an iterator range [begin, end).
			// Bool() - Yields sequence {false, true}.
			// Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product
			// for the math savvy) of the values generated
			// by the N generators.
			//
			// For more details, see comments at the definitions of these functions below
			// in this file.
			//
			// The following statement will instantiate tests from the FooTest test suite
			// each with parameter values "meeny", "miny", and "moe".

			INSTANTIATE_TEST_SUITE_P(InstantiationName,
			FooTest,
			Values("meeny", "miny", "moe"));

			// To distinguish different instances of the pattern, (yes, you
			// can instantiate it more than once) the first argument to the
			// INSTANTIATE_TEST_SUITE_P macro is a prefix (which must be non-empty) that
			// will be added to the actual test suite name. Remember to pick unique prefixes
			// for different instantiations. The tests from the instantiation above will
			// have these names:
			//
			// * InstantiationName/FooTest.DoesBlah/0 for "meeny"
			// * InstantiationName/FooTest.DoesBlah/1 for "miny"
			// * InstantiationName/FooTest.DoesBlah/2 for "moe"
			// * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
			// * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
			// * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
			//
			// You can use these names in --gtest_filter.
			//
			// This statement will instantiate all tests from FooTest again, each
			// with parameter values "cat" and "dog":

			const char* pets[] = {"cat", "dog"};
			INSTANTIATE_TEST_SUITE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));

			// The tests from the instantiation above will have these names:
			//
			// * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat"
			// * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
			// * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
			// * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
			//
			// Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests
			// in the given test suite, whether their definitions come before or
			// AFTER the INSTANTIATE_TEST_SUITE_P statement.
			//
			// Please also note that generator expressions (including parameters to the
			// generators) are evaluated in InitGoogleTest(), after main() has started.
			// This allows the user on one hand, to adjust generator parameters in order
			// to dynamically determine a set of tests to run and on the other hand,
			// give the user a chance to inspect the generated tests with Google Test
			// reflection API before RUN_ALL_TESTS() is executed.
			//
			// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
			// for more examples.
			//
			// In the future, we plan to publish the API for defining new parameter
			// generators. But for now this interface remains part of the internal
			// implementation and is subject to change.
			//
			//
			// A parameterized test fixture must be derived from testing::Test and from
			// testing::WithParamInterface<T>, where T is the type of the parameter
			// values. Inheriting from TestWithParam<T> satisfies that requirement because
			// TestWithParam<T> inherits from both Test and WithParamInterface. In more
			// complicated hierarchies, however, it is occasionally useful to inherit
			// separately from Test and WithParamInterface. For example:

			class BaseTest : public ::testing::Test {
			// You can inherit all the usual members for a non-parameterized test
			// fixture here.
			};

			class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
			// The usual test fixture members go here too.
			};

			TEST_F(BaseTest, HasFoo) {
			// This is an ordinary non-parameterized test.
			}

			TEST_P(DerivedTest, DoesBlah) {
			// GetParam works just the same here as if you inherit from TestWithParam.
			EXPECT_TRUE(foo.Blah(GetParam()));
			}

			// * start and end must have the same type. That type may be any integral or
