/* 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.
