Rob Wu 7ff6e8a1dc chore: Stop swallowing errors in .sh tests
The Bash shell scripts ignored errors in all but the last line.
This commit adds `set -eo pipefail` to fix the issue:

`set -e` causes the script to exit as soon as any command exits with a
non-zero exit code. When pipes are used, this flag only applies to the
last command in a pipe. The `set -o pipefail` option ensures that the
script is also exited with a non-zero exit code when any command in the
pipe fails.

ExE Boss 80f4caf453 chore: Use `delete window.browser` in `setupTestDOMWindow` (#128)
This patch remove a workaround introduced in #2, because it has been fixed upstream and the workaround is not needed anymore (when using a nodejs version >= 8).

Luca Greco 5d186bae84 test(browsers-smoketests): Run a set of smoke tests on both Chrome and Firefox
This commit introduces tape as the test framework used to define the tests in the
test extension contexts and send them to the nodejs script that orchestrate the
test run.

The nodejs script has also been migrated from mocha to tape, it uses the custom test
helpers provided to setup the test environment (e.g. create a temporary dir
for the test extension, copy the last polyfill build, bundle tape to be used
in the test extension, start the browser which run the test extension
and finally collect the results of the test extension) and then it merges all the
tap logs collected from every test extension into a single "per browser" test suite.

- updated travis nodejs environment to nodejs 8
- uses tape to collect test results from inside the test extension
- added test case to check polyfill 'existing browser API object' detection
- added test for expected rejection on tabs.sendMessage with an invalid tabId
- added test with multiple listeners which resolves to undefined and null
- optionally run chrome smoketests with --enable-features=NativeCrxBindings

Rob Wu 67b3780d38 fix: Lazily initialize API via the original target (#71)
Originally, the polyfill created a Proxy with the original API object as
the target. This was changed to `Object.create(chrome)` because not
doing so would prevent the `browser.devtools` API from working because
the devtools API object is assigned as a read-only & non-configurable
property (#57).

However, that action itself caused a new bug: Whenever an API object
is dereferenced via the `browser` namespace, the original API is no
longer available in the `chrome` namespace, and trying to access the
API through `chrome` returns `undefined` plus the "Previous API
instantiation failed" warning (#58).
This is because Chrome lazily initializes fields in the `chrome`
API, but on the object from which the property is accessed, while
the polyfill accessed the property through an object with the
prototype set to `chrome` instead of directly via chrome.

To fix that, `Object.create(chrome)` was replaced with
`Object.assign({}, chrome)`. This fixes both of the previous issues
because
1) It is still a new object.
2) All lazily initialized fields are explicitly initialized.

This fix created a new issue: In Chrome some APIs cannot be used even
though they are visible in the API (e.g. `chrome.clipboard`), so
calling `Object.assign({}, chrome)` causes an error to be printed to
the console (#70).

To solve this, I use `Object.create(chrome)` again as a proxy target,
but dereference the API via the original target (`chrome`) to not
regress on #58.
Besides fixing the bug, this also reduces the performance impact
of the API because all API fields are lazily initialized again,
instead of upon start-up.

This fixes #70.

Luca Greco 61d92ea79b feat: Added devtools.inspectedWindow.eval and devtools.panels.create to wrapped APIs.
To be able to wrap the devtools API namespaces, this patch applies the
following changes:

- fix: Prevent Proxy violation exception on the read-only/non-configurable devtools property
  by using an empty object with the `chrome` API object as its prototype
  as the root Proxy target (the Proxy instances returned for the
  `chrome` API object) and add a related test case.

- fix: Added support for a new `singleCallbackArg` metadata property,
  which prevents devtools.panels.create to resolve an array of
  parameters (See the related Chromium issue at
  https://bugs.chromium.org/p/chromium/issues/detail?id=768159)
  and add the related test cases.

- test: Changes to the test case related to proxy getter/setter behavior
  on non wrapped properties:

  in the "deletes proxy getter/setter that are not wrapped" test case from
  the "test-proxied-properties.js" test file, we ensure that when a
  getter/setter is called for a "non-wrapped" property, the getter/setter
  is going to affect the original target object, unfortunately this in
  not true anymore for the root object (the `chrome` API object) because
  we are using an empty object (which has the `chrome` API object as its
  prototype and it is not exposed outside of the polyfill sources)
  as the target of the Proxy instance related to it,
  this change to the target of the Proxy has been needed to prevent the
  TypeError exception raised by the Proxy instance when we try to access
  the "devtools" property (which is non-configurable and read-only on the
  `chrome` API object).

Joseph Frazier f9248e62e7 feat: library wrapped as an UMD module
This addresses [issue 7] by making it possible for users to run:

```sh
npm install webextension-polyfill
```

and download a module that they can use with a bundler as follows:

```js
import browser from 'webextension-polyfill';
```

Also, add a [prepublish script] so that users who clone the repo don't
need to run `grunt` manually. In addition, specify [files] in
package.json so that this module can be published to npm without
including miscellanea. This can be verified by running:

```sh
npm pack && tar -tvf webextension-polyfill-0.1.0.tgz
```

Luca Greco 6cca044a5c test: add more test cases to reach a full code coverage.
- if the a browser global already exists, it should not be overridden
- use Object.defineProperty on the wrapped browser global
  (and test "has" for cached properties)
- delete a property defined with Object.defineProperty
- methods that are not wrapped are proxied correctly
- the special onMessage wrapper should not wrap a listener that is not
  a function
- test that a returned rejected Promise on the onMessage listener
  is turned in the parameter of the sendResponse callback
