+* Help us understand which parts of the spec are tested or not
+Lots of the following rules are arbitrary but the value is realized in
+consistency instead of adhering to the 'perfect' style.
+
+We want the test suite to be navigable. Developers should be able to easily
+find the file or test that is relevant to their work.
+* Tests should be arranged in files according to which piece of the spec they
+ test
+* Files should be named using a consistent pattern
+* HTML files should include useful meta tags
+ * `<title>` for controlling labels in results pages
+ * `<link rel="help">` to point at the relevant piece of the spec
+
+We want the test suite to run consistently. Flaky tests are counterproductive.
+* Prefer `promise_test` to `async_test`
+ * Note that there’s [still potential for some concurrency][2]; use
+ `add_cleanup()` if needed
+
+We want the tests to be readable. Tests should be written in a modern style
+with recurring patterns.
+* 80 character line limits where we can
+* Consistent use of anonymous functions
+ * prefer
+ ```
+ const func1 = param1 => {
+ body();
+ }
+ const func2 = (param1, param2) => {
+ body();
+ }
+ fn(param => {
+ body();
+ });
+ ```
+
+ over
+
+ ```
+ function func1(param1) {
+ body();
+ }
+ function func2(param1, param2) {
+ body();
+ }
+ fn(function(param) {
+ body();
+ });
+ ```
+
+* Prefer `const` (or, if needed, `let`) to `var`
+* Contain use of ‘.sub’ in filenames to known helper utilities where possible
+ * E.g. prefer use of get-host-info.sub.js to `{{host}}` or `{{ports[0]}}`
+ expressions
+* Avoid use of webperftestharness[extension].js as it’s a layer of cognitive
+ overhead between test content and test intent
+ * Helper .js files are still encouraged where it makes sense but we want
+ to avoid a testing framework that is specific to Resource Timing (or
+ web performance APIs, in general).
+* Prefer [`fetch_tests_from_window`][3] to collect test results from embedded
+ iframes instead of hand-rolled `postMessage` approaches
+* Use the [`assert_*`][4] family of functions to check conformance to the spec
+ but throw exceptions explicitly when the test itself is broken.
+ * A failed assert indicates "the implementation doesn't conform to the
+ spec"
+ * Other uncaught exceptions indicate "the test case itself has a bug"
+* Where possible, we want tests to be scalable - adding another test case
+ should be as simple as calling the tests with new parameters, rather than
+ copying an existing test and modifying it.
