+Web Animations Test Suite
+=========================
+
+Specification: https://w3c.github.io/web-animations/
+
+
+Guidelines for writing tests
+----------------------------
+
+* Try to follow the spec outline where possible.
+
+ For example, if you want to test setting the start time, you might be
+ tempted to put all the tests in:
+
+ > `/web-animations/interfaces/Animation/startTime.html`
+
+ However, in the spec most of the logic is in the “Set the animation
+ start time“ procedure in the “Timing model” section.
+
+ Instead, try something like:
+
+ > * `/web-animations/timing-model/animations/set-the-animation-start-time.html`<br>
+ > Tests all the branches and inputs to the procedure as defined in the
+ > spec (using the `Animation.startTime` API).
+ > * `/web-animations/interfaces/Animation/startTime.html`<br>
+ > Tests API-layer specific issues like mapping unresolved values to
+ > null, etc.
+
+ On that note, two levels of subdirectories is enough even if the spec has
+ deeper nesting.
+
+ Note that most of the existing tests in the suite _don't_ do this well yet.
+ That's the direction we're heading, however.
+
+* Test the spec.
+
+ * If the spec defines a timing calculation that is directly
+ reflected in the iteration progress
+ (i.e. `anim.effect.getComputedTiming().progress`), test that instead
+ of calling `getComputedStyle(elem).marginLeft`.
+
+ * Likewise, don't add needless tests for `anim.playbackState`.
+ The playback state is a calculated value based on other values.
+ It's rarely necessary to test directly unless you need, for example,
+ to check that a pending task is scheduled (which isn't observable
+ elsewhere other than waiting for the corresponding promise to
+ complete).
+
+* Try to keep tests as simple and focused as possible.
+
+ e.g.
+
+ ```javascript
+ test(function(t) {
+ var anim = createDiv(t).animate(null);
+ assert_class_string(anim, 'Animation', 'Returned object is an Animation');
+ }, 'Element.animate() creates an Animation object');
+ ```
+
+ ```javascript
+ test(function(t) {
+ assert_throws({ name: 'TypeError' }, function() {
+ createDiv(t).animate(null, -1);
+ });
+ }, 'Setting a negative duration throws a TypeError');
+ ```
+
+ ```javascript
+ promise_test(function(t) {
+ var animation = createDiv(t).animate(null, 100 * MS_PER_SEC);
+ return animation.ready.then(function() {
+ assert_greater_than(animation.startTime, 0, 'startTime when running');
+ });
+ }, 'startTime is resolved when running');
+ ```
+
+ If you're generating complex test loops and factoring out utility functions
+ that affect the logic of the test (other than, say, simple assertion utility
+ functions), you're probably doing it wrong.
+
+ It should be possible to understand exactly what the test is doing at a
+ glance without having to scroll up and down the test file and refer to
+ other files.
+
+ See Justin Searls' presentation, [&ldquo;How to stop hating your
+ tests&rdquo;](http://blog.testdouble.com/posts/2015-11-16-how-to-stop-hating-your-tests.html)
+ for some tips on making your tests simpler.
+
+* Assume tests will run on under-performing hardware where the time between
+ animation frames might run into 10s of seconds.
+ As a result, animations that are expected to still be running during
+ the test should be at least 100s in length.
+
+* Avoid using `GLOBAL_CONSTS` that make the test harder to read.
+ It's fine to repeat the the same parameter values like `100 * MS_PER_SEC`
+ over and over again since it makes it easy to read and debug a test in
+ isolation.
+ Remember, even if we do need to make all tests take, say 200s each, text
+ editors are very good at search and replace.
+
+* Use the `assert_times_equal` assertion for comparing calculated times.
+ It tests times are equal using the precision recommended in the spec whilst
+ allowing implementations to override the function to meet their own
+ precision requirements.
+
+* There are quite a few bad tests in the repository. We're learning as
+ we go. Don't just copy them blindly&mdash;please fix them!

+// NOTE TO THE POOR PERSON WHO HAS TO MERGE THIS WITH THE TEST OF THE SAME
+// NAME FROM BLINK
+//
+// There is a pull request from Blink at:
+//
+// https://github.com/w3c/web-platform-tests/pull/3328
+//
+// which this file will surely conflict with.
+//
+// However, those tests cover a different part of the same algorithm. They
+// are mostly concerned with testing events and promises rather than the
+// timing part of the algorithm.
+//
+// The tests below cover the first part of the algorithm. So, please keep both
+// sets of tests and delete this comment. Preferably put the tests in this
+// file first.
+//
+// Thank you!
