/**
|
||
* Tests Places query serialization. Associated bug is
|
||
* https://bugzilla.mozilla.org/show_bug.cgi?id=370197
|
||
*
|
||
* The simple idea behind this test is to try out different combinations of
|
||
* query switches and ensure that queries are the same before serialization
|
||
* as they are after de-serialization.
|
||
*
|
||
* In the code below, "switch" refers to a query option -- "option" in a broad
|
||
* sense, not nsINavHistoryQueryOptions specifically (which is why we refer to
|
||
* them as switches, not options). Both nsINavHistoryQuery and
|
||
* nsINavHistoryQueryOptions allow you to specify switches that affect query
|
||
* strings. nsINavHistoryQuery instances have attributes hasBeginTime,
|
||
* hasEndTime, hasSearchTerms, and so on. nsINavHistoryQueryOptions instances
|
||
* have attributes sortingMode, resultType, excludeItems, etc.
|
||
*
|
||
* Ideally we would like to test all 2^N subsets of switches, where N is the
|
||
* total number of switches; switches might interact in erroneous or other ways
|
||
* we do not expect. However, since N is large (21 at this time), that's
|
||
* impractical for a single test in a suite.
|
||
*
|
||
* Instead we choose all possible subsets of a certain, smaller size. In fact
|
||
* we begin by choosing CHOOSE_HOW_MANY_SWITCHES_LO and ramp up to
|
||
* CHOOSE_HOW_MANY_SWITCHES_HI.
|
||
*
|
||
* There are two more wrinkles. First, for some switches we'd like to be able to
|
||
* test multiple values. For example, it seems like a good idea to test both an
|
||
* empty string and a non-empty string for switch nsINavHistoryQuery.searchTerms.
|
||
* When switches have more than one value for a test run, we use the Cartesian
|
||
* product of their values to generate all possible combinations of values.
|
||
*
|
||
* Second, we need to also test serialization of multiple nsINavHistoryQuery
|
||
* objects at once. To do this, we remember the previous NUM_MULTIPLE_QUERIES
|
||
* queries we tested individually and then serialize them together. We do this
|
||
* each time we test an individual query. Thus the set of queries we test
|
||
* together loses one query and gains another each time.
|
||
*
|
||
* To summarize, here's how this test works:
|
||
*
|
||
* - For n = CHOOSE_HOW_MANY_SWITCHES_LO to CHOOSE_HOW_MANY_SWITCHES_HI:
|
||
* - From the total set of switches choose all possible subsets of size n.
|
||
* For each of those subsets s:
|
||
* - Collect the test runs of each switch in subset s and take their
|
||
* Cartesian product. For each sequence in the product:
|
||
* - Create nsINavHistoryQuery and nsINavHistoryQueryOptions objects
|
||
* with the chosen switches and test run values.
|
||
* - Serialize the query.
|
||
* - De-serialize and ensure that the de-serialized query objects equal
|
||
* the originals.
|
||
* - For each of the previous NUM_MULTIPLE_QUERIES
|
||
* nsINavHistoryQueryOptions objects o we created:
|
||
* - Serialize the previous NUM_MULTIPLE_QUERIES nsINavHistoryQuery
|
||
* objects together with o.
|
||
* - De-serialize and ensure that the de-serialized query objects
|
||
* equal the originals.
