How to break dependencies without modifying production code?
From my initial readings on unit testing (I'm a beginner) it is wise to put all of your setups and tests in a separate project from the code being tested. This seems ideal to me, as well. However, I've recently begun reading The Art of Unit Testing, trying to discover how to break dependencies on things such as database calls. The met...
How can I make a generic unit test for all my classes that inherit from a base class?
I am creating a base class (or base entity) since all my database tables will have a companyID field. In my unit tests, I have to make sure the companyID value is correct.

Taking unit testing to the next level
Over the past year or so I have been developing my TDD chops so that I am now fairly good at the essentials - writing tests first, mocking frameworks, testing as small things as possible, DI etc. However I feel like there are still a lot of things that I am not getting out of unit testing. For example, I often find that unit testing in...

File reading and testable code
I have a piece of java code which reads strings from a file and creates a map out of the strings. As this code depends on a file, unit testing is clumsy. How does one design such pieces so that code can be unit tested? One approach that I can think of is, instead of this piece taking a file as an argument it can take an input stream. I...
Access Django testserver from Django test
Hi! I want to write a unit test that performs HTTP requests directly (instead of using django.test.client.Client). If you're curious why - it's because I want to test a Thrift-over-HTTP API that I expose from my Django application - and I want to use the Thrift client in the unit test. The problem is that during tests, the server is n...

Hi, i am using TypeMock Isolator to fake the tables on my DataContext like this: Isolate.Swap.CallsOn(ctx.GetTable<TTable>()).WithCallsTo(content); I now can fill the "database" with arbitrary data on each test. In order to get meaningful data for the test scenario into the DataContext i usually have to create 3-5 objects. Now, the p...

A great deal of the business logic is spread across all of the tiers including in stored procedures.

Continuous unit testing with Pydev (Python and Eclipse)
Is there a way to integrate background unit tests with the Pydev Eclipse environment? My unit tests run well, but I would like to integrate them to run in the background based on source file changes (e.g. with nose) and to integrate the result back to Eclipse (I'm thinking big red X when tests fail with a console and trace log view).
