| 9 | /* Description: |
| 10 | * This test defines a series of elementatry test steps that perform |
| 11 | * a single or a small group of canvas API calls. Each test step is |
| 12 | * used in several test cases that verify that different types of SkCanvas |
| 13 | * flavors and derivatives pass it and yield consistent behavior. The |
| 14 | * test cases analyse results that are queryable through the API. They do |
| 15 | * not look at rendering results. |
| 16 | * |
| 17 | * Adding test stepss: |
| 18 | * The general pattern for creating a new test step is to write a test |
| 19 | * function of the form: |
| 20 | * |
| 21 | * static void MyTestStepFunction(SkCanvas* canvas, |
| 22 | * skiatest::Reporter* reporter, |
| 23 | * CanvasTestStep* testStep) |
| 24 | * { |
| 25 | * canvas->someCanvasAPImethod(); |
| 26 | * (...) |
| 27 | * REPORTER_ASSERT_MESSAGE(reporter, (...), \ |
| 28 | * testStep->assertMessage()); |
| 29 | * } |
| 30 | * |
| 31 | * The definition of the test step function should be followed by an |
| 32 | * invocation of the TEST_STEP macro, which generates a class and |
| 33 | * instance for the test step: |
| 34 | * |
| 35 | * TEST_STEP(MyTestStep, MyTestStepFunction) |
| 36 | * |
| 37 | * There are also short hand macros for defining simple test steps |
| 38 | * in a single line of code. A simple test step is a one that is made |
| 39 | * of a single canvas API call. |
| 40 | * |
| 41 | * SIMPLE_TEST_STEP(MytestStep, someCanvasAPIMethod()); |
| 42 | * |
| 43 | * There is another macro called SIMPLE_TEST_STEP_WITH_ASSERT that |
| 44 | * works the same way as SIMPLE_TEST_STEP, and additionally verifies |
| 45 | * that the invoked method returns a non-zero value. |
