Implements the .net MongoDb 2.5 drivers interfaces, to allow unit testing
The origina check in was pretty much the results of a 2 day "can this be done" experiment, and the answer to which is "Yes this is absolutely doable"
Project Ethos.
- I'm reluctant to pull in anything that isn't .net standard.
I'm used to working with an IoC container, if one becomes necessary I'd nearly hand roll a simple one,
or include the code for TinyIoC rather than introduce a NuGet dependency
Done, to do and things that aren't difficult
No brainer things
- Serialization of entities between Bson and back
Done & mostly done
- Barebones of an InMemoryClient object & InMemoryDatabase object
They’re functional but may need a small amount of work - Find methods
- InsertOne, InsertMany
- DeleteOne, DeleteMany
- Count
- Filtering list of Objects on any operators I could find / think of ($and, $in, $exists, etc), simple to add more.
- Getting a typed .net value from a field (harder than it sounds).
- Projections - need unit tests
- Updates - only 4 or 5 operators, $set, $unset, $inc, $push, need more operators and unit tests
To-do
- Aggregations Once projections are done, there’s little new here beyond grouping, which is easily achieved with a dictionary or a HashSet It will need Filtering, matching & projections and grouping. It feels like it should be scary but I don’t think Aggregations will be rocket science.
- Sessions, I’ve largely been ignoring sessions as I haven't used them and I’m not sure what they’re used for.
- Views, I’ve completely ignored views as I haven't used them, however once projections are done views might be straightforward to knock off.
Testing
I have some nunit tests put together for some of what I’ve done so far, but what would be good is to expand on those, and have a set of data, a set of operations on that data.
We load the initial data set into MongoDb, run the operations on it, get the expected result.
Then load the initial data set into the InMemoryDb, run the operations on it, and compare that final dataset against the expected result.
Something to do the last part would be a good thing to have.
