Add FileWriter test utilities.

• Component: DOM
• Status: RESOLVED FIXED

[Eric U.]

We need real tests for FileWriter.  There are a lot of tasks common to each test; this bug is for the basic common utilities and one or two tests using them.  More tests will follow in a separate bug.

Is there a strong reason you don't use shouldBe/shouldBeTrue here?  This script already depend on some functions that are defined in js-test-pre.js (and fs-worker-common.js).

If we really want full-functional, colorized testPassed/testFailed/description functions, I think we should just include js-test-pre.js.  Replicating all the code here doesn't look good to me...

If we want to include js/resources in workers test we'll need some more tricks in chromium code and it'll automatically allow us to include js-test-pre.js here too.  In that case we won't need fs-worker-test-pre.js any more -- let's forget about it and include js-test-pre.js.

Unwrapped a bunch of lines.

I don't trust it.  I've got a boolean value already, which I can just test with assert.  I'm not sure why shouldBe turns everything into strings and then calls eval on them, but it looks really complicated to me.  I'd be happier getting rid of that stuff entirely where it's not absolutely necessary.

That was a note to me to fix up the code before checking it in; there was a bug that prevented that test from being runnable, but it's fixed now.

Removed a lot of replication, shared code where possible.

Thanks for cleaning this up!

> LayoutTests/ChangeLog:8
> +        Cleaning up shared test utility files caused the output of a bunch of existing tests change slightly, so I've rebuilt the expectation files.  While fixing this, I found that some filesystem worker .html files were including javascript only appropriate for the workers themselves, so I removed the extra includes.

Just to clarify... fs-worker-common.js was intentionally included in .html files for shouldBe methods (since we hadn't included js-test-pre.js).

> LayoutTests/fast/filesystem/file-writer-truncate-extend.html:15
> +</html>

Fyi, this does not apply to this test (and others that have .js files under resources/ but not under script-tests/) but might be worth mentioning...

Many .html files that include js-test-pre.js are generated by a script (make-script-test-wrappers) from script-tests/TEMPLATE.html and corresponding .js files under script-tests.  And most of them are not indented (since same/copy-past'ed TEMPLATE.html is often used).

Not sure if it was intentional, but "\n" wouldn't work as a line break in testFailed or in other span's.

Btw do we need try-catch here?  Async methods usually do not throw exceptions and we don't catch exceptions at all in most other places.

> LayoutTests/fast/filesystem/resources/fs-worker-test-post.js:2
> +successfullyParsed = true;

Now that we include js/resources/js-test-pre.js we'd better replace this with js/resources/js-test-post.js as well.  (And we'll be able to remove this entire file.)

Also could you put this "successfullyParsed = true;" line between <script></script> and after startWorker(...) in the .html files, as you did in file-writer-truncate-extend.html?  I think it should be placed at the end of the main script body.

> LayoutTests/fast/filesystem/resources/fs-worker-test-pre.js:9

No need of {} for one line blocks (here and below).

If we want to handle worker messages differently how about using fixed-length prefixes for all messages?

> LayoutTests/fast/filesystem/resources/fs-worker-test-pre.js:14
> +            description(event.data.substring(13));

For this one do we care whether it is printed out by description() or by debug()?
If we have description in the document's js file it gets replaced by the worker's one.

> LayoutTests/fast/filesystem/workers/async-operations-expected.txt:15

This duplicated 'successfullyParsed is true' lines look confusing, how about prefixing all the worker's output with "Worker output:" or something?

> LayoutTests/fast/filesystem/workers/async-operations.html:4

Sorry for putting up requests, but could we rename this to fs-worker-test-util.js or something?  (As fs-worker-test-post will be gone now)

> LayoutTests/fast/filesystem/workers/file-from-file-entry-sync.html:3

I think you'd want to include the css file here since many of your changes are for pretty-printing the results.

I think it's ok not to use shouldBe here, and it's true that shouldBe does some (sometime undesired) stringify and evals, but it's also true that more than 1000 js files rely on this method(s).  It must be 'trustable' and otherwise we'll need to fix it.

(oops my previous comment looks hard to understand)

Adding these lines around line 167 should do. (It makes the necessary resource files copied while setting up the test environment)
+    AddResourceForLayoutTest(worker_test_dir.AppendASCII("js"),
+                             resource_dir);

Since worker tests for filesystem are not enabled yet you can file a bug and assign it to me if you want.  I can fix it when I enable them.

Ah, I see.  I was confused because it also contained functions that called postMessage.  Anyway, I've taken your recommendations for cleanup, and so everything's much nicer now.

True, but if e.g. somebody corrupts fileEntryForCleanup, we could get an exception calling the method, and I'd like to call finishJSTest even if we fail.  But if you still think it's better to remove it, I will.

Removed the descriptions from the .html files, to match the non-worker tests.

True...but I suppose somewhere in those tests there's a test that actually needed the 'eval' behavior and the different scoping, and we really don't.

Hit 'publish' before adding more comments... overall looks good, except that this one seems to lack the ChangeLog and have the duplicated entries of fs-worker-test-util.js.  Thanks for cleaning up them all.

Also most of comments in .js files are wrapped at 80 chars; I would unwrap them to conform with the coding style.

I'm not sure how the ChangeLog got dropped, but it should be in this patch.

The odd duplication of fs-worker-test-util.js is because I both renamed it from its original location and edited it.

It looks like the .html files should be generated like what happens normally for script tests. Is this a future change?

Please consider addressing the successfully parsed issue (and removing alert :) ), and this will be good to go.

We usually wrap lines in ChangeLog before they get this long.

> +finishJSTest();

This looks wrong here and in the other places where this happened.

Typically 
 var successfullyParsed = true;
is last so that it is clear the whole file was parsed correctly (and it would be checked in js-test-post.js).

As mentioned before, I think this should be done elsewhere.

I'm not sure what you mean by this.  I generated the .html files by hand, by running the tests in Chromium.  They don't run in DumpRenderTree yet because we don't have support for these APIs in non-Chromium browsers yet.  The filewriter-worker stuff is in that other changelist you're reviewing, so that's future stuff too.

This is tricky.  This test file is shared by the DOM test [where you can then include js-test-post.js if you want] and the worker test [where it's the main script for the worker, and nothing can follow it].  Given the current setup, I think we have the choice of either not bothering with the successfullyParsed stuff at all, or doing it something like this.

An alternative would be to do something like the SQLDatabase tests, in which there's a common test-runner for all worker tests, and you send it commands.  Then you can tell it to import the test script THEN the post-test script.

I'm not sure that the successfullyParsed thing is really adding much to these worker tests; I'm inclined just to remove it.  What do you think?

Fwiw, the point was most of the filesystem tests under resources run in async mode (jsTestIsAsync == true) and for those tests successfullyParsed is tested in finishJSTest() method but not in js-test-post.js.
That's why we used to have successfullyParsed test in our own finishJSTest() for workers (in fs-worker-common.js).
If you don't think we should test this flag we can just drop it.  (I thought it was useful while debugging test scripts)

They don't run in DumpRenderTree yet because we don't have support for these APIs in non-Chromium browsers yet.  The filewriter-worker stuff is in that other changelist you're reviewing, so that's future stuff too.

I think he means what I wrote in comment #6 ("Many .html files that include js-test-pre.js are generated by a script (make-script-test-wrappers) from...").  David, our .js files are under resources but not under script-tests (where the script assumes) mainly because I wanted to share as many .js files as possible for worker and non-worker tests.  We'll need to modify the script or rearrange the whole test scripts to use the script to generate html files.

OK, now workers no longer bother checking successfullyParsed.  I left the variable in the shared scripts, though, so the non-worker tests that use them still benefit from the check.
