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:
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:
python bin/sync-and-gyp
ninja -C out/Debug dm
out/Debug/dm --match newgmtest
3. Run the GM inside SampleApp:
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
