Browser chrome tests – mozilla mdn anoxic brain injury prognosis

Note: Be careful when naming your functions and variables. Since the test files are executed in the same scope as the browser window, conflicting variable names could cause trouble while running the tests. anxiety disorder You should attempt to reduce the side effects of the testing code and "clean up" after yourself, to avoid influencing other tests.

The comparison functions are identical to those supported by Mochitests, see how the comparison functions work in the Mochitest documentation for more details. The EventUtils helper functions are available on the EventUtils object defined in the global scope.

The test file name must be prefixed with "browser_", and must have a file extension of ".js".


Files that don’t match this pattern will be ignored by the test harness. Using a descriptive file name is strongly encouraged instead of just using a bug number.

You can collect common utils and helpers in a file called head.js, that must live in the same folder as the browser-chrome tests. This file will be injected into the test scope for each test living in the same folder. Notice that any function call in head.js main scope will run before the main test() method. separation anxiety disorder icd 10 Asynchronous tests

The test suite also supports asynchronous tests, using the same function names as Mochitest. Call waitForExplicitFinish() from test() if you want to delay reporting a result until after test() has returned. Call finish() once the test is complete. Be aware that the test harness will mark tests that take too long to complete as FAILED (the current timeout is 30 seconds). function test() {

If your test is randomly timing out and you think that’s just due to it taking too long, you can extend the timeout. Be aware that this is not a solution; you should investigate why your test is taking so long, since it’s most likely due to a bad test design or a performance problem. If you can rewrite the test to make is shorter, split it into smaller tests, or find why it’s taking so long, you should really do that instead! function test() {

Any exceptions thrown under test() will be caught and reported in the test output as a failure. reflex anoxic seizures in adults symptoms Exceptions thrown outside of test() (e.g. in a timeout, event handler, etc) will not be caught, but will result in a timed out test if they prevent finish() from being called. Cleaning up after yourself

If you need to do special clean up after running your test, you can register a cleanup function that is guaranteed to be run after your test finishes. You can call registerCleanupFunction() at any point in your test, even in head.js if you need to register a clean up function for all tests in that folder. Notice that you can register as many clean up functions as you will. Clean up functions are also guaranteed to be called if your test timeouts, so you can ensure that in case of timeouts you won’t pollute next running tests and causing them to fail. registerCleanupFunction(function() {

When writing tests, design for failure. It is much better to call registerCleanupFunction() than doing the cleanup after you have successfully run your tests because the cleanup functions are always called, no matter what. For instance, if you change a preference you want to make sure that the preference is always reset so that it doesn’t impact other tests after yours. hypoxia and anoxia difference Adding a new browser chrome test to the tree

To add a new browser chrome test to the tree, add it to the browser.ini file in the same folder as the test. Also remember that the test file’s name must begin with "browser_" for the test to be recognized as a browser chrome test. If you are adding the first tests in a directory, make sure to also include any head.js you added to support-files, and additionally, ensure that your browser.ini is referenced by a moz.build file somewhere, such as: BROWSER_CHROME_MANIFESTS += [
