3132 //
3133 // Typical usage:
3134 //
3135 //   1. You stream a bunch of values to a Message object.
3136 //      It will remember the text in a stringstream.
3137 //   2. Then you stream the Message object to an ostream.
3138 //      This causes the text in the Message to be streamed
3139 //      to the ostream.
3140 //
3141 // For example;
3142 //
3143 //   testing::Message foo;
3144 //   foo << 1 << " != " << 2;
3145 //   std::cout << foo;
3146 //
3147 // will print "1 != 2".
3148 //
3149 // Message is not intended to be inherited from.  In particular, its
3150 // destructor is not virtual.
3151 //
3152 // Note that stringstream behaves differently in gcc and in MSVC.  You
3153 // can stream a NULL char pointer to it in the former, but not in the
3154 // latter (it causes an access violation if you do).  The Message
3155 // class hides this difference by treating a NULL char pointer as
3156 // "(null)".

8505 //   1. It generates a warning if there is more than one active

8514 //
8515 //   4. The parent process checks the exit code and error message of

8535 // On the regular expressions used in death tests:
8536 //
8537 //   On POSIX-compliant systems (*nix), we use the <regex.h> library,
8538 //   which uses the POSIX extended regex syntax.
8539 //
8540 //   On other platforms (e.g. Windows), we only support a simple regex
8541 //   syntax implemented as part of Google Test.  This limited
8542 //   implementation should be enough most of the time when writing
8543 //   death tests; though it lacks many features you can find in PCRE
8544 //   or POSIX extended regex syntax.  For example, we don't support
8545 //   union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
8546 //   repetition count ("x{5,7}"), among others.
8547 //
8548 //   Below is the syntax that we do support.  We chose it to be a
8549 //   subset of both PCRE and POSIX extended regex, so it's easy to
8550 //   learn wherever you come from.  In the following: 'A' denotes a
8551 //   literal character, period (.), or a single \\ escape sequence;
8552 //   'x' and 'y' denote regular expressions; 'm' and 'n' are for
8553 //   natural numbers.
8554 //
8555 //     c     matches any literal character c
8556 //     \\d   matches any decimal digit
8557 //     \\D   matches any character that's not a decimal digit
8558 //     \\f   matches \f
8559 //     \\n   matches \n
8560 //     \\r   matches \r
8561 //     \\s   matches any ASCII whitespace, including \n
8562 //     \\S   matches any character that's not a whitespace
8563 //     \\t   matches \t
8564 //     \\v   matches \v
8565 //     \\w   matches any letter, _, or decimal digit
8566 //     \\W   matches any character that \\w doesn't match
8567 //     \\c   matches any literal character c, which must be a punctuation
8568 //     .     matches any single character except \n
8569 //     A?    matches 0 or 1 occurrences of A
8570 //     A*    matches 0 or many occurrences of A
8571 //     A+    matches 1 or many occurrences of A
8572 //     ^     matches the beginning of a string (not that of each line)
8573 //     $     matches the end of a string (not that of each line)
8574 //     xy    matches x followed by y
8575 //
8576 //   If you accidentally use PCRE or POSIX extended regex features
8577 //   not implemented by us, you will get a run-time failure.  In that
8578 //   case, please try to rewrite your regular expression within the
8579 //   above syntax.
8580 //
8581 //   This implementation is *not* meant to be as highly tuned or robust
8582 //   as a compiled regex library, but should perform well enough for a
8583 //   death test, which already incurs significant overhead by launching
8584 //   a child process.
8585 //
8586 // Known caveats:
8587 //
8588 //   A "threadsafe" style death test obtains the path to the test
8589 //   program from argv[0] and re-executes it in the sub-process.  For
8590 //   simplicity, the current implementation doesn't search the PATH
8591 //   when launching the sub-process.  This means that the user must
8592 //   invoke the test program via a path that contains at least one
8593 //   path separator (e.g. path/to/foo_test and
8594 //   /absolute/path/to/bar_test are fine, but foo_test is not).  This
8595 //   is rarely a problem as people usually don't put the test binary

8779 #if 0
8780 
8781 // To write value-parameterized tests, first you should define a fixture

8783 // another inheritance scheme that's sometimes useful in more complicated
8784 // class hierarchies), where the type of your parameter values.
8785 // TestWithParam<T> is itself derived from testing::Test. T can be any
8786 // copyable type. If it's a raw pointer, you are responsible for managing the
8787 // lifespan of the pointed values.
8788 
8789 class FooTest : public ::testing::TestWithParam<const char*> {
8790   // You can implement all the usual class fixture members here.
8791 };
8792 
8793 // Then, use the TEST_P macro to define as many parameterized tests
8794 // for this fixture as you want. The _P suffix is for "parameterized"
8795 // or "pattern", whichever you prefer to think.
8796 
8797 TEST_P(FooTest, DoesBlah) {
8798   // Inside a test, access the test parameter with the GetParam() method
8799   // of the TestWithParam<T> class:
8800   EXPECT_TRUE(foo.Blah(GetParam()));

8808 // Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
8809 // case with any set of parameters you want. Google Test defines a number
8810 // of functions for generating test parameters. They return what we call
8811 // (surprise!) parameter generators. Here is a  summary of them, which
8812 // are all in the testing namespace:
8813 //
8814 //
8815 //  Range(begin, end [, step]) - Yields values {begin, begin+step,
8816 //                               begin+step+step, ...}. The values do not
8817 //                               include end. step defaults to 1.
8818 //  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
8819 //  ValuesIn(container)        - Yields values from a C-style array, an STL
8820 //  ValuesIn(begin,end)          container, or an iterator range [begin, end).
8821 //  Bool()                     - Yields sequence {false, true}.
8822 //  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
8823 //                               for the math savvy) of the values generated
8824 //                               by the N generators.
8825 //
8826 // For more details, see comments at the definitions of these functions below
8827 // in this file.
8828 //
8829 // The following statement will instantiate tests from the FooTest test case

8836 // To distinguish different instances of the pattern, (yes, you

8866 // in the given test case, whether their definitions come before or
8867 // AFTER the INSTANTIATE_TEST_CASE_P statement.
8868 //
8869 // Please also note that generator expressions (including parameters to the
8870 // generators) are evaluated in InitGoogleTest(), after main() has started.
8871 // This allows the user on one hand, to adjust generator parameters in order
8872 // to dynamically determine a set of tests to run and on the other hand,
8873 // give the user a chance to inspect the generated tests with Google Test
8874 // reflection API before RUN_ALL_TESTS() is executed.
8875 //
8876 // You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
8877 // for more examples.
8878 //
8879 // In the future, we plan to publish the API for defining new parameter
8880 // generators. But for now this interface remains part of the internal
8881 // implementation and is subject to change.

8884 // A parameterized test fixture must be derived from testing::Test and from
8885 // testing::WithParamInterface<T>, where T is the type of the parameter
8886 // values. Inheriting from TestWithParam<T> satisfies that requirement because
8887 // TestWithParam<T> inherits from both Test and WithParamInterface. In more
8888 // complicated hierarchies, however, it is occasionally useful to inherit
8889 // separately from Test and WithParamInterface. For example:
8890 
8891 class BaseTest : public ::testing::Test {
8892   // You can inherit all the usual members for a non-parameterized test
8893   // fixture here.

8993 // A "smart" pointer type with reference tracking.  Every pointer to a
8994 // particular object is kept on a circular linked list.  When the last pointer
8995 // to an object is destroyed or reassigned, the object is deleted.
8996 //
8997 // Used properly, this deletes the object when the last reference goes away.
8998 // There are several caveats:
8999 // - Like all reference counting schemes, cycles lead to leaks.
9000 // - Each smart pointer is actually two pointers (8 bytes instead of 4).
9001 // - Every time a pointer is assigned, the entire list of pointers to that
9002 //   object is traversed.  This class is therefore NOT SUITABLE when there
9003 //   will often be more than two or three pointers to a particular object.
9004 // - References are only tracked as long as linked_ptr<> objects are copied.
9005 //   If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
9006 //   will happen (double deletion).
9007 //
9008 // A good use of this class is storing object references in STL containers.
9009 // You can safely put linked_ptr<> in a vector<>.
9010 // Other uses may not be as good.
9011 //
9012 // Note: If you use an incomplete type with linked_ptr<>, the class
9013 // *containing* linked_ptr<> must have a constructor and destructor (even
9014 // if they do nothing!).
9015 //
9016 // Bill Gibbons suggested we use something like this.
9017 //
9018 // Thread Safety:
9019 //   Unlike other linked_ptr implementations, in this implementation
9020 //   a linked_ptr object is thread-safe in the sense that:
9021 //     - it's safe to copy linked_ptr objects concurrently,
9022 //     - it's safe to copy *from* a linked_ptr and read its underlying
9023 //       raw pointer (e.g. via get()) concurrently, and
9024 //     - it's safe to write to two linked_ptrs that point to the same
9025 //       shared object concurrently.
9026 // TODO(wan@google.com): rename this to safe_linked_ptr to avoid
9027 // confusion with normal linked_ptr.

9227 // This file implements a universal value printer that can print a
9228 // value of any type T:
9229 //
9230 //   void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
9231 //
9232 // A user can teach this function how to print a class type T by
9233 // defining either operator<<() or PrintTo() in the namespace that
9234 // defines T.  More specifically, the FIRST defined function in the
9235 // following list will be used (assuming T is defined in namespace
9236 // foo):
9237 //
9238 //   1. foo::PrintTo(const T&, ostream*)
9239 //   2. operator<<(ostream&, const T&) defined in either foo or the
9240 //      global namespace.
9241 //
9242 // If none of the above is defined, it will print the debug string of
9243 // the value if it is a protocol buffer, or print the raw bytes in the
9244 // value otherwise.
9245 //
9246 // To aid debugging: when T is a reference type, the address of the
9247 // value is also printed; when T is a (const) char pointer, both the
9248 // pointer value and the NUL-terminated string it points to are
9249 // printed.
9250 //
9251 // We also provide some convenient wrappers:
9252 //
9253 //   // Prints a value to a string.  For a (const or not) char
9254 //   // pointer, the NUL-terminated string (but not the pointer) is
9255 //   // printed.
9256 //   std::string ::testing::PrintToString(const T& value);
9257 //
9258 //   // Prints a value tersely: for a reference type, the referenced
9259 //   // value (but not the address) is printed; for a (const or not) char
9260 //   // pointer, the NUL-terminated string (but not the pointer) is
9261 //   // printed.
9262 //   void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
9263 //
9264 //   // Prints value using the type inferred by the compiler.  The difference
9265 //   // from UniversalTersePrint() is that this function prints both the
9266 //   // pointer and the NUL-terminated string for a (const or not) char pointer.
9267 //   void ::testing::internal::UniversalPrint(const T& value, ostream*);
9268 //
9269 //   // Prints the fields of a tuple tersely to a string vector, one
9270 //   // element for each field. Tuple support must be enabled in
9271 //   // gtest-port.h.
9272 //   std::vector<string> UniversalTersePrintTupleFieldsToStrings(
9273 //       const Tuple& value);
9274 //
9275 // Known limitation:
9276 //
9277 // The print primitives print the elements of an STL-style container
9278 // using the compiler-inferred type of *iter where iter is a
9279 // const_iterator of the container.  When const_iterator is an input
9280 // iterator but not a forward iterator, this inferred type may not
9281 // match value_type, and the print output may be incorrect.  In
9282 // practice, this is rarely a problem as for most containers
9283 // const_iterator is a forward iterator.  We'll fix this if there's an
9284 // actual need for it.  Note that this fix cannot rely on value_type
9285 // being defined as many user-defined container types don't have
9286 // value_type.

17600 //   2. Defining predicate-format functions to be
17601 //      used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
17602 //
17603 // For example, if you define IsEven predicate:
17604 //
17605 //   testing::AssertionResult IsEven(int n) {
17606 //     if ((n % 2) == 0)
17607 //       return testing::AssertionSuccess();

17610 //   }
17611 //
17612 // Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
17613 // will print the message
17614 //
17615 //   Value of: IsEven(Fib(5))
17616 //     Actual: false (5 is odd)
17617 //   Expected: true
17618 //
17619 // instead of a more opaque
17620 //
17621 //   Value of: IsEven(Fib(5))
17622 //     Actual: false
17623 //   Expected: true
17624 //
17625 // in case IsEven is a simple Boolean predicate.
17626 //
17627 // If you expect your predicate to be reused and want to support informative
17628 // messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
17629 // about half as often as positive ones in our tests), supply messages for
17630 // both success and failure cases:
17631 //
17632 //   testing::AssertionResult IsEven(int n) {
17633 //     if ((n % 2) == 0)
17634 //       return testing::AssertionSuccess() << n << " is even";
17635 //     else
17636 //       return testing::AssertionFailure() << n << " is odd";
17637 //   }
17638 //
17639 // Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
17640 //
17641 //   Value of: IsEven(Fib(6))
17642 //     Actual: true (8 is even)
17643 //   Expected: false
17644 //
17645 // NB: Predicates that support negative Boolean assertions have reduced
17646 // performance in positive ones so be careful not to use them in tests
17647 // that have lots (tens of thousands) of positive Boolean assertions.
17648 //
17649 // To use this class with EXPECT_PRED_FORMAT assertions such as:
17650 //
17651 //   // Verifies that Foo() returns an even number.
17652 //   EXPECT_PRED_FORMAT1(IsEven, Foo());
17653 //
17654 // you need to define:
17655 //
17656 //   testing::AssertionResult IsEven(const char* expr, int n) {
17657 //     if ((n % 2) == 0)
17658 //       return testing::AssertionSuccess();
17659 //     else
17660 //       return testing::AssertionFailure()
17661 //         << "Expected: " << expr << " is even\n  Actual: it's " << n;
17662 //   }
17663 //
17664 // If Foo() returns 5, you will see the following message:

19717 //   1. It is possible to make a user-defined type work with

19719 //   comparison operators and is thus discouraged by the Google C++
19720 //   Usage Guide.  Therefore, you are advised to use the
19721 //   {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
19722 //   equal.
19723 //
19724 //   2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
19725 //   pointers (in particular, C strings).  Therefore, if you use it
19726 //   with two C strings, you are testing how their locations in memory
19727 //   are related, not how their content is related.  To compare two C
19728 //   strings by content, use {ASSERT|EXPECT}_STR*().
19729 //
19730 //   3. {ASSERT|EXPECT}_EQ(expected, actual) is preferred to
19731 //   {ASSERT|EXPECT}_TRUE(expected == actual), as the former tells you
19732 //   what the actual value is when it fails, and similarly for the
19733 //   other comparisons.
19734 //
19735 //   4. Do not depend on the order in which {ASSERT|EXPECT}_??()
