-Writing Unit and Rendering Tests
-================================
-
-Writing a Unit Test
--------------------
-
-1.  Add a file `tests/NewUnitTest.cpp`:
-
-    <!--?prettify lang=cc?-->
-
-        /*
-         * Copyright ........
-         *
-         * Use of this source code is governed by a BSD-style license
-         * that can be found in the LICENSE file.
-         */
-        #include "Test.h"
-        DEF_TEST(NewUnitTest, reporter) {
-            if (1 + 1 != 2) {
-                ERRORF(reporter, "%d + %d != %d", 1, 1, 2);
-            }
-            bool lifeIsGood = true;
-            REPORTER_ASSERT(reporter, lifeIsGood);
-        }
-
-2.  Add a line to `gyp/tests.gypi`:
-
-        '../tests/NewUnitTest.cpp',
-
-3.  Recompile and run test:
-
-        ./gyp_skia
-        ninja -C out/Debug dm
-        out/Debug/dm --match NewUnitTest
-
-Writing a Rendering Test
-------------------------
-
-1.  Add a file `gm/newgmtest.cpp`:
-
-    <!--?prettify lang=cc?-->
-
-        /*
-         * Copyright ........
-         *
-         * Use of this source code is governed by a BSD-style license
-         * that can be found in the LICENSE file.
-         */
-        #include "gm.h"
-        DEF_SIMPLE_GM(newgmtest, canvas, 128, 128) {
-            canvas->clear(SK_ColorWHITE);
-            SkPaint p;
-            p.setStrokeWidth(2);
-            canvas->drawLine(16, 16, 112, 112, p);
-        }
-
-2.  Add a line to `gyp/gmslides.gypi`:
-
-        '../gm/newgmtest.cpp',
-
-3.  Recompile and run test:
-
-        ./gyp_skia
-        ninja -C out/Debug dm
-        out/Debug/dm --match newgmtest
