Search condition ids are now indexed from 0, and always saved
contiguously (no more 'fixGaps' option), since they're just in an array
in the API. (They're still returned as an object from
Zotero.Search.prototype.getConditions() because it's easier for the
advanced search window to not have to deal with shifting ids between
saves.)
Also:
- Return an object from `Zotero.Search.prototype.getConditions()`
instead of an array.
- Add support function `getPromiseError(promise)` to return the error
thrown from a chain of promises, or false if none. (We could make an
`assert.throwsAsync()`, but this allows testing of various properties
such as `.name`, which even the built-in `assert.throws()` can't
test.)
- Clarify some search save errors
Also some support code that was useful here and will probably be
useful for other tests. This is a pretty complicated thing to test, but
it seems to work.
Implements the beginnings of unit testing infrastructure using
mocha/chai. The unit tests can be run locally using test/runtests.sh,
although this will need tweaks to run on Windows. They should also run
on commit using Travis-CI.
The unit tests themselves live in test/tests. The index.js file
specifies separate test sets, which can be run individually by calling
test/runtests.sh <testsets>. Right now there is only a single unit
test, but hopefully we'll have more soon...
