How do I Moq a method that has an optional argument in its signature without explicitly specifying i
...venience for calling code, but I think that you should be explicit in your tests. Say you could leave out specifying the bool parameter. What happens if, in future, someone changes the default value of b to true? This will lead to failing tests (and rightfully so), but they will be more difficult to...

CruiseControl [.Net] vs TeamCity for continuous integration?
...reat deal of power. The build statistics page that shows build times, unit test count, pass rate etc. is very nice. TeamCity's project home page is also very valuable.

What is so bad about singletons? [closed]
...erently cause code to be tightly coupled. This makes faking them out under test rather difficult in many cases.
They carry state around for the lifetime of the application. Another hit to testing since you can end up with a situation where tests need to be ordered which is a big no no for unit tests...
How to validate an email address in JavaScript
...Using regular expressions is probably the best way. You can see a bunch of tests here (taken from chromium)
function validateEmail(email) {

Test if number is odd or even
