8/* Description:
9 * This test defines a series of elementatry test steps that perform
10 * a single or a small group of canvas API calls. Each test step is
11 * used in several test cases that verify that different types of SkCanvas
12 * flavors and derivatives pass it and yield consistent behavior. The
13 * test cases analyse results that are queryable through the API. They do
14 * not look at rendering results.
15 *
16 * Adding test stepss:
17 * The general pattern for creating a new test step is to write a test
18 * function of the form:
19 *
rmistry@google.comd6176b02012-08-23 18:14:13 +000020 * static void MyTestStepFunction(SkCanvas* canvas,
junov@chromium.org1cc8f6f2012-02-22 21:00:42 +000021 * skiatest::Reporter* reporter,
22 * CanvasTestStep* testStep)
23 * {
24 * canvas->someCanvasAPImethod();
25 * (...)
26 * REPORTER_ASSERT_MESSAGE(reporter, (...), \
27 * testStep->assertMessage());
28 * }
29 *
30 * The definition of the test step function should be followed by an
31 * invocation of the TEST_STEP macro, which generates a class and
32 * instance for the test step:
33 *
34 * TEST_STEP(MyTestStep, MyTestStepFunction)
35 *
36 * There are also short hand macros for defining simple test steps
37 * in a single line of code. A simple test step is a one that is made
38 * of a single canvas API call.
39 *
40 * SIMPLE_TEST_STEP(MytestStep, someCanvasAPIMethod());
41 *
42 * There is another macro called SIMPLE_TEST_STEP_WITH_ASSERT that
43 * works the same way as SIMPLE_TEST_STEP, and additionally verifies
44 * that the invoked method returns a non-zero value.
