37 | // Value-parameterized tests allow you to test your code with different | |
38 | // parameters without writing multiple copies of the same test. | |

40 | // Here is how you use value-parameterized tests: | |
41 | ||
42 | #if 0 | |
43 | ||
44 | // To write value-parameterized tests, first you should define a fixture | |
45 | // class. It is usually derived from testing::TestWithParam<T> (see below for | |
46 | // another inheritance scheme that's sometimes useful in more complicated | |
47 | // class hierarchies), where the type of your parameter values. | |
48 | // TestWithParam<T> is itself derived from testing::Test. T can be any | |
49 | // copyable type. If it's a raw pointer, you are responsible for managing the | |
50 | // lifespan of the pointed values. | |
51 | ||
52 | class FooTest : public ::testing::TestWithParam<const char*> { | |
53 | // You can implement all the usual class fixture members here. | |
54 | }; | |
55 | ||
56 | // Then, use the TEST_P macro to define as many parameterized tests | |
57 | // for this fixture as you want. The _P suffix is for "parameterized" | |
58 | // or "pattern", whichever you prefer to think. | |
59 | ||
60 | TEST_P(FooTest, DoesBlah) { | |
61 | // Inside a test, access the test parameter with the GetParam() method | |
62 | // of the TestWithParam<T> class: | |
63 | EXPECT_TRUE(foo.Blah(GetParam())); | |
64 | ... | |
65 | } | |
66 | ||
67 | TEST_P(FooTest, HasBlahBlah) { | |
68 | ... | |
69 | } | |

1e59de90 | 71 | // Finally, you can use INSTANTIATE_TEST_SUITE_P to instantiate the test |
31f18b77 FG |
72 | // case with any set of parameters you want. Google Test defines a number |
73 | // of functions for generating test parameters. They return what we call | |
1e59de90 | 74 | // (surprise!) parameter generators. Here is a summary of them, which |
31f18b77 FG |
75 | // are all in the testing namespace: |
76 | // | |
77 | // | |
78 | // Range(begin, end [, step]) - Yields values {begin, begin+step, | |
79 | // begin+step+step, ...}. The values do not | |
80 | // include end. step defaults to 1. | |
81 | // Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}. | |
82 | // ValuesIn(container) - Yields values from a C-style array, an STL | |
83 | // ValuesIn(begin,end) container, or an iterator range [begin, end). | |
84 | // Bool() - Yields sequence {false, true}. | |
85 | // Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product | |
86 | // for the math savvy) of the values generated | |
87 | // by the N generators. | |
88 | // | |
89 | // For more details, see comments at the definitions of these functions below | |
90 | // in this file. | |
91 | // | |
1e59de90 | 92 | // The following statement will instantiate tests from the FooTest test suite |

132 | // Please also note that generator expressions (including parameters to the | |

138 | // | |
139 | // You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc | |

141 | // | |
142 | // In the future, we plan to publish the API for defining new parameter | |
