40 // Value-parameterized tests allow you to test your code with different
41 // parameters without writing multiple copies of the same test.
42 //
43 // Here is how you use value-parameterized tests:
44
45 #if 0
46
47 // To write value-parameterized tests, first you should define a fixture
48 // class. It is usually derived from testing::TestWithParam<T> (see below for
49 // another inheritance scheme that's sometimes useful in more complicated
50 // class hierarchies), where the type of your parameter values.
51 // TestWithParam<T> is itself derived from testing::Test. T can be any
52 // copyable type. If it's a raw pointer, you are responsible for managing the
53 // lifespan of the pointed values.
54
55 class FooTest : public ::testing::TestWithParam<const char*> {
56 // You can implement all the usual class fixture members here.
57 };
58
59 // Then, use the TEST_P macro to define as many parameterized tests
60 // for this fixture as you want. The _P suffix is for "parameterized"
61 // or "pattern", whichever you prefer to think.
62
63 TEST_P(FooTest, DoesBlah) {
64 // Inside a test, access the test parameter with the GetParam() method
65 // of the TestWithParam<T> class:
66 EXPECT_TRUE(foo.Blah(GetParam()));
67 ...
68 }
69
70 TEST_P(FooTest, HasBlahBlah) {
71 ...
72 }
73
74 // Finally, you can use INSTANTIATE_TEST_SUITE_P to instantiate the test
75 // case with any set of parameters you want. Google Test defines a number
76 // of functions for generating test parameters. They return what we call
77 // (surprise!) parameter generators. Here is a summary of them, which
78 // are all in the testing namespace:
79 //
80 //
81 // Range(begin, end [, step]) - Yields values {begin, begin+step,
82 // begin+step+step, ...}. The values do not
83 // include end. step defaults to 1.
84 // Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}.
85 // ValuesIn(container) - Yields values from a C-style array, an STL
86 // ValuesIn(begin,end) container, or an iterator range [begin, end).
87 // Bool() - Yields sequence {false, true}.
88 // Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product
89 // for the math savvy) of the values generated
90 // by the N generators.
91 //
92 // For more details, see comments at the definitions of these functions below
93 // in this file.
94 //
95 // The following statement will instantiate tests from the FooTest test suite
96 // each with parameter values "meeny", "miny", and "moe".
97
98 INSTANTIATE_TEST_SUITE_P(InstantiationName,
99 FooTest,
100 Values("meeny", "miny", "moe"));
101
102 // To distinguish different instances of the pattern, (yes, you
103 // can instantiate it more than once) the first argument to the
104 // INSTANTIATE_TEST_SUITE_P macro is a prefix that will be added to the
105 // actual test suite name. Remember to pick unique prefixes for different
106 // instantiations. The tests from the instantiation above will have
107 // these names:
108 //
109 // * InstantiationName/FooTest.DoesBlah/0 for "meeny"
110 // * InstantiationName/FooTest.DoesBlah/1 for "miny"
111 // * InstantiationName/FooTest.DoesBlah/2 for "moe"
112 // * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
113 // * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
114 // * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
115 //
116 // You can use these names in --gtest_filter.
117 //
118 // This statement will instantiate all tests from FooTest again, each
119 // with parameter values "cat" and "dog":
120
121 const char* pets[] = {"cat", "dog"};
122 INSTANTIATE_TEST_SUITE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));

127 // * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
128 // * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
129 // * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
130 //
131 // Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests
132 // in the given test suite, whether their definitions come before or
133 // AFTER the INSTANTIATE_TEST_SUITE_P statement.
134 //
135 // Please also note that generator expressions (including parameters to the
136 // generators) are evaluated in InitGoogleTest(), after main() has started.
137 // This allows the user on one hand, to adjust generator parameters in order
138 // to dynamically determine a set of tests to run and on the other hand,
139 // give the user a chance to inspect the generated tests with Google Test
140 // reflection API before RUN_ALL_TESTS() is executed.
141 //
142 // You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
143 // for more examples.
144 //
145 // In the future, we plan to publish the API for defining new parameter
146 // generators. But for now this interface remains part of the internal
147 // implementation and is subject to change.
148 //
149 //
150 // A parameterized test fixture must be derived from testing::Test and from
151 // testing::WithParamInterface<T>, where T is the type of the parameter
152 // values. Inheriting from TestWithParam<T> satisfies that requirement because
153 // TestWithParam<T> inherits from both Test and WithParamInterface. In more
154 // complicated hierarchies, however, it is occasionally useful to inherit
155 // separately from Test and WithParamInterface. For example:
156
157 class BaseTest : public ::testing::Test {
158 // You can inherit all the usual members for a non-parameterized test
159 // fixture here.
160 };

168 }
