canvas state coherence test case passes with sequences of draw commands that trigger flushes and purges of deferred draw commands. This CL confirms that using SkGPipe fixes the deferred canvas issues that are the root problem of crbug.com/133432 BUG=https://code.google.com/p/chromium/issues/detail?id=133432 Review URL: https://codereview.appspot.com/6416049 git-svn-id: http://skia.googlecode.com/svn/trunk@4687 2bbb7eff-a529-9590-31e7-b0007b416f81

/* 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.
