1840// * {ASSERT|EXPECT}_EQ(v1, v2): Tests that v1 == v2
1841// * {ASSERT|EXPECT}_NE(v1, v2): Tests that v1 != v2
1842// * {ASSERT|EXPECT}_LT(v1, v2): Tests that v1 < v2
1843// * {ASSERT|EXPECT}_LE(v1, v2): Tests that v1 <= v2

1846//
1847// When they are not, Google Test prints both the tested expressions and
1848// their actual values. The values must be compatible built-in types,
1849// or you will get a compiler error. By "compatible" we mean that the
1850// values can be compared by the respective operator.
1851//
1852// Note:
1853//
1854// 1. It is possible to make a user-defined type work with
1855// {ASSERT|EXPECT}_??(), but that requires overloading the
1856// comparison operators and is thus discouraged by the Google C++
1857// Usage Guide. Therefore, you are advised to use the
1858// {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
1859// equal.
1860//
1861// 2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
1862// pointers (in particular, C strings). Therefore, if you use it
1863// with two C strings, you are testing how their locations in memory
1864// are related, not how their content is related. To compare two C
1865// strings by content, use {ASSERT|EXPECT}_STR*().
1866//
1867// 3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to
1868// {ASSERT|EXPECT}_TRUE(v1 == v2), as the former tells you
1869// what the actual value is when it fails, and similarly for the
1870// other comparisons.
1871//
1872// 4. Do not depend on the order in which {ASSERT|EXPECT}_??()
1873// evaluate their arguments, which is undefined.
1874//
1875// 5. These macros evaluate their arguments exactly once.
1876//
1877// Examples:
1878//
1879// EXPECT_NE(Foo(), 5);
1880// EXPECT_EQ(a_pointer, NULL);
1881// ASSERT_LT(i, array_size);
1882// ASSERT_GT(records.size(), 0) << "There is no record left.";
