@ -22,81 +22,14 @@ those cases you can [whitelist test files](#updating-the-whitelist)
to suppress the errors. In all other cases, follow the instructions
below to fix all errors reported.
* **CONSOLE**: Test-file line has a `console.*(...)` call; **fix**: remove
the `console.*(...)` call (and in some cases, consider adding an
`assert_*` of some kind in place of it).
<!--

code.
-->
* **CR AT EOL**: Test-file line ends with CR (U+000D) character; **fix**:
reformat file so each line just has LF (U+000A) line ending (standard,
cross-platform "Unix" line endings instead of, e.g., DOS line endings).
* **EARLY-TESTHARNESSREPORT**: Test file has an instance of
`<script src='/resources/testharnessreport.js'>` prior to
`<script src='/resources/testharness.js'>`; **fix**: flip the order.
* **GENERATE_TESTS**: Test file line has a generate_tests call; **fix**: remove
the call and call `test()` a number of times instead.
* **INDENT TABS**: Test-file line starts with one or more tab characters;
**fix**: use spaces to replace any tab characters at beginning of lines.
* **INVALID-TIMEOUT**: Test file with `<meta name='timeout'...>` element
that has a `content` attribute whose value is not `long`; **fix**:
replace the value of the `content` attribute with `long`.
* **LATE-TIMEOUT**: Test file with `<meta name="timeout"...>` element after
`<script src='/resources/testharnessreport.js'>` element ; **fix**: move
the `<meta name="timeout"...>` element to precede the `script` element.
* **LAYOUTTESTS APIS**: Test file uses `eventSender`, `testRunner`, or
`internals` which are LayoutTests-specific APIs used in WebKit/Blink.
* **MALFORMED-VARIANT**: Test file with a `<meta name='variant'...>`
element whose `content` attribute has a malformed value; **fix**: ensure
the value of the `content` attribute starts with `?` or `#` or is empty.
* **MISSING-LINK**: CSS test file is missing a link to a spec. **fix**: Ensure that there is a `<link rel="help" href="[url]">` for the spec.
* Note: `MISSING-LINK` is designed to ensure that the CSS build tool can find the tests. Note that the CSS build system is primarily used by [test.csswg.org/](http://test.csswg.org/), which doesn't use `wptserve`, so `*.any.js` and similar tests won't work there; stick with the `.html` equivalent.
* **MISSING-TESTHARNESSREPORT**: Test file is missing an instance of
`<script src='/resources/testharnessreport.js'>`; **fix**: ensure each
test file contains `<script src='/resources/testharnessreport.js'>`.
* **MULTIPLE-TESTHARNESS**: Test file with multiple instances of
`<script src='/resources/testharness.js'>`; **fix**: ensure each test
has only one `<script src='/resources/testharness.js'>` instance.
* **MULTIPLE-TESTHARNESSREPORT**: Test file with multiple instances of
`<script src='/resources/testharnessreport.js'>`; **fix**: ensure each test
has only one `<script src='/resources/testharnessreport.js'>` instance.
* **MULTIPLE-TIMEOUT**: Test file with multiple `<meta name="timeout"...>`
elements; **fix**: ensure each test file has only one instance of a
`<meta name="timeout"...>` element.
* **PARSE-FAILED**: Test file failed parsing by manifest builder; **fix**:
examine the file to find the causes of any parse errors, and fix them.
* **PATH LENGTH**: Test file's pathname has a total length greater than 150
characters; **fix**: use shorter filename to rename the test file.
* **PRINT STATEMENT**: A server-side python support file contains a `print`
statement; **fix**: remove the `print` statement or replace it with
something else that achieves the intended effect (e.g., a logging call).
* **SET TIMEOUT**: Test-file line has `setTimeout(...)` call; **fix**:
replace all `setTimeout(...)` calls with `step_timeout(...)` calls.
* **TRAILING WHITESPACE**: Test-file line has trailing whitespace; **fix**:
remove trailing whitespace from all lines in the file.
* **VARIANT-MISSING**: Test file with a `<meta name='variant'...>` element
that's missing a `content` attribute; **fix**: add a `content` attribute
with an appropriate value to the `<meta name='variant'...>` element.
* **W3C-TEST.ORG**: Test-file line has the string `w3c-test.org`; **fix**:
either replace the `w3c-test.org` string with the expression
`{{host}}:{{ports[http][0]}}` or a generic hostname like `example.org`.
