 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.  Recompile and run test:
 
-        ./gyp_skia
+        python bin/sync-and-gyp
         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.  Recompile and run test:
 
-        ./gyp_skia
+        python bin/sync-and-gyp
         ninja -C out/Debug dm
         out/Debug/dm --match newgmtest
 
 3.  Run the GM inside SampleApp:
 
-        ./gyp_skia
+        python bin/sync-and-gyp
         ninja -C out/Debug SampleApp
         out/Debug/SampleApp --slide GM:newgmtest
 
     On MacOS, try this:
 
         out/Debug/SampleApp.app/Contents/MacOS/SampleApp --slide GM:newgmtest
