177 // A class for indicating whether an assertion was successful. When
178 // the assertion wasn't successful, the AssertionResult object
179 // remembers a non-empty message that describes how it failed.
180 //
181 // To create an instance of this class, use one of the factory functions
182 // (AssertionSuccess() and AssertionFailure()).
183 //
184 // This class is useful for two purposes:
185 // 1. Defining predicate functions to be used with Boolean test assertions
186 // EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
187 // 2. Defining predicate-format functions to be
188 // used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
189 //
190 // For example, if you define IsEven predicate:
191 //
192 // testing::AssertionResult IsEven(int n) {
193 // if ((n % 2) == 0)
194 // return testing::AssertionSuccess();
195 // else
196 // return testing::AssertionFailure() << n << " is odd";
197 // }
198 //
199 // Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
200 // will print the message
201 //
202 // Value of: IsEven(Fib(5))
203 // Actual: false (5 is odd)
204 // Expected: true
205 //
206 // instead of a more opaque
207 //
208 // Value of: IsEven(Fib(5))
209 // Actual: false
210 // Expected: true
211 //
212 // in case IsEven is a simple Boolean predicate.
213 //
214 // If you expect your predicate to be reused and want to support informative
215 // messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
216 // about half as often as positive ones in our tests), supply messages for
217 // both success and failure cases:
218 //
219 // testing::AssertionResult IsEven(int n) {
220 // if ((n % 2) == 0)
221 // return testing::AssertionSuccess() << n << " is even";
222 // else
223 // return testing::AssertionFailure() << n << " is odd";
224 // }
225 //
226 // Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
227 //
228 // Value of: IsEven(Fib(6))
229 // Actual: true (8 is even)
230 // Expected: false
231 //
232 // NB: Predicates that support negative Boolean assertions have reduced
233 // performance in positive ones so be careful not to use them in tests
234 // that have lots (tens of thousands) of positive Boolean assertions.
235 //
236 // To use this class with EXPECT_PRED_FORMAT assertions such as:
237 //
238 // // Verifies that Foo() returns an even number.
239 // EXPECT_PRED_FORMAT1(IsEven, Foo());
240 //
241 // you need to define:
242 //
243 // testing::AssertionResult IsEven(const char* expr, int n) {
244 // if ((n % 2) == 0)
245 // return testing::AssertionSuccess();
246 // else
247 // return testing::AssertionFailure()
248 // << "Expected: " << expr << " is even\n Actual: it's " << n;
249 // }
250 //
251 // If Foo() returns 5, you will see the following message:
252 //
253 // Expected: Foo() is even
254 // Actual: it's 5

1890 // Note:
1891 //
1892 // 1. It is possible to make a user-defined type work with

1895 // Usage Guide. Therefore, you are advised to use the
1896 // {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
1897 // equal.
1898 //
1899 // 2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
1900 // pointers (in particular, C strings). Therefore, if you use it
1901 // with two C strings, you are testing how their locations in memory
1902 // are related, not how their content is related. To compare two C
1903 // strings by content, use {ASSERT|EXPECT}_STR*().
1904 //
1905 // 3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to
1906 // {ASSERT|EXPECT}_TRUE(v1 == v2), as the former tells you
1907 // what the actual value is when it fails, and similarly for the
