+
+// Minitest is a minimalistic unit testing framework designed specifically
+// for the Android support library.
+//
+// - Unit tests must be written in C++, but no C++ runtime implementation
+//   is either required or _supported_. This is by design.
+//
+// _ Inspired by GoogleTest, you can use the TEST macro to define a new
+//   test case easily, and it can contain EXPECT_XX|ASSERT_XX statements.
+//
+//   For example:
+//
+//      TEST(stdio, strlen) {
+//        EXPECT_EQ(3, strlen("foo"));
+//        EXPECT_EQ(1, srlen("a"));
+//      }
+//
+//   However, there are important differences / limitations:
+//
+//   o You cannot stream strings into an except or assert statement.
+//     Minitest provides a TEST_TEXT macro to do that instead.
+//
+//     In other words, replace:
+//
+//       EXPECT_EQ(expected, expression) << "When checking 'foo'";
+//
+//     With:
+//       TEST_TEXT << "When checking 'foo'";
+//       EXPECT_EQ(expected, expression);
+//
+//    The context text is only printed on failure.
+//
+//   o TEST_F() is not supported (for now).
+//
+//   o EXPECT/ASSERT statements only work inside a TESET() function, not
+//     in a function called by it.
+//
+//   o No test death detection.
+//
+// - You can use minitest::Format() to stream formatted output into
+//   a TEST_TEXT context, as in:
+//
+//      for (size_t n = 0; n < kMaxCount; n++) {
+//        TEST_TEXT << "Checking string : "
+//                  << minitest;:Format("%z/%z", n+1, kMaxCount);
+//        EXPECT_EQ(kExpected[n], Foo(kString[n]));
+//      }
+//
