| /* Description: |
| * This test defines a series of elementatry test steps that perform |
| * a single or a small group of canvas API calls. Each test step is |
| * used in several test cases that verify that different types of SkCanvas |
| * flavors and derivatives pass it and yield consistent behavior. The |
| * test cases analyse results that are queryable through the API. They do |
| * not look at rendering results. |
| * |
| * Adding test stepss: |
| * The general pattern for creating a new test step is to write a test |
| * function of the form: |
| * |
| * static void MyTestStepFunction(SkCanvas* canvas, |
| * skiatest::Reporter* reporter, |
| * CanvasTestStep* testStep) |
| * { |
| * canvas->someCanvasAPImethod(); |
| * (...) |
| * REPORTER_ASSERT_MESSAGE(reporter, (...), \ |
| * testStep->assertMessage()); |
| * } |
| * |
| * The definition of the test step function should be followed by an |
| * invocation of the TEST_STEP macro, which generates a class and |
| * instance for the test step: |
| * |
| * TEST_STEP(MyTestStep, MyTestStepFunction) |
| * |
| * There are also short hand macros for defining simple test steps |
| * in a single line of code. A simple test step is a one that is made |
| * of a single canvas API call. |
| * |
| * SIMPLE_TEST_STEP(MytestStep, someCanvasAPIMethod()); |
| * |
| * There is another macro called SIMPLE_TEST_STEP_WITH_ASSERT that |
| * works the same way as SIMPLE_TEST_STEP, and additionally verifies |
| * that the invoked method returns a non-zero value. |
