// 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.

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_CASE_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 case

// each with parameter values "meeny", "miny", and "moe".

INSTANTIATE_TEST_CASE_P(InstantiationName,

                        FooTest,

                        Values("meeny", "miny", "moe"));

// To distinguish different instances of the pattern, (yes, you

// can instantiate it more then once) the first argument to the

// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the

// actual test case 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_CASE_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_CASE_P will instantiate all tests

// in the given test case, whether their definitions come before or

// AFTER the INSTANTIATE_TEST_CASE_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()));

// Google Test uses these generators to produce parameters for value-

// with a particular generator, Google Test creates and runs tests

// for each element in the sequence produced by the generator.

//

// In the following sample, tests from test case FooTest are instantiated

// class FooTest : public TestWithParam<int> { ... };

// Range() returns generators providing sequences of values in a range.

//

// Synopsis:

// Range(start, end)

//   - returns a generator producing a sequence of values {start, start+1,

//     start+2, ..., }.

// Range(start, end, step)

//   - returns a generator producing a sequence of values {start, start+step,

//     start+step+step, ..., }.

// Notes:

//   * The generated sequences never include end. For example, Range(1, 5)

//     returns a generator producing a sequence {1, 2, 3, 4}. Range(1, 9, 2)

//     returns a generator producing {1, 3, 5, 7}.

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

//     floating-point type or a user defined type satisfying these conditions:

//     * It must be assignable (have operator=() defined).

//     * It must have operator+() (operator+(int-compatible type) for

//       two-operand version).

//     * It must have operator<() defined.

//     Elements in the resulting sequences will also have that type.

//   * Condition start < end must be satisfied in order for resulting sequences

//     to contain any elements.

// ValuesIn() function allows generation of tests with parameters coming from

// Synopsis:

// ValuesIn(const Container& container)

//   - returns a generator producing sequences with elements from

// ValuesIn(Iterator begin, Iterator end)

//   - returns a generator producing sequences with elements from

//     a range [begin, end) defined by a pair of STL-style iterators. These

//     iterators can also be plain C pointers.

//

// Please note that ValuesIn copies the values from the containers

// passed in and keeps them to generate tests in RUN_ALL_TESTS().

//

// Examples:

//

// This instantiates tests from test case StringTest

// each with C-string values of "foo", "bar", and "baz":

//

// const char* strings[] = {"foo", "bar", "baz"};

// INSTANTIATE_TEST_CASE_P(StringSequence, SrtingTest, ValuesIn(strings));

//

// This instantiates tests from test case StlStringTest

// each with STL strings with values "a" and "b":

//

// ::std::vector< ::std::string> GetParameterStrings() {

//   ::std::vector< ::std::string> v;

// each with parameter values 'a' and 'b':

//

// ::std::list<char> GetParameterChars() {

//   ::std::list<char> list;

//   list.push_back('a');

//   list.push_back('b');

// Combine() allows the user to combine two or more sequences to produce

// Synopsis:

// Combine(gen1, gen2, ..., genN)

//   - returns a generator producing sequences with elements coming from

//     the Cartesian product of elements from the sequences generated by

//     gen1, gen2, ..., genN. The sequence elements will have a type of

//     tuple<T1, T2, ..., TN> where T1, T2, ..., TN are the types

//     of elements from sequences produces by gen1, gen2, ..., genN.

//

// Combine can have up to $maxtuple arguments. This number is currently limited

// by the maximum number of elements in the tuple implementation used by Google

// Test.

//

// Example:

//

// This will instantiate tests in test case AnimalTest each one with

// the parameter values tuple("cat", BLACK), tuple("cat", WHITE),

// tuple("dog", BLACK), and tuple("dog", WHITE):

//

// enum Color { BLACK, GRAY, WHITE };

// class AnimalTest

//     : public testing::TestWithParam<tuple<const char*, Color> > {...};

//

// TEST_P(AnimalTest, AnimalLooksNice) {...}

//                                 Values(BLACK, WHITE)));

// Boolean flags:

//

// class FlagDependentTest

//     : public testing::TestWithParam<tuple<bool, bool> > {

//   virtual void SetUp() {

//     // Assigns external_flag_1 and external_flag_2 values from the tuple.

//     tie(external_flag_1, external_flag_2) = GetParam();
