This is not the most common thing to do, but still common enough to have its own name. This technique is called Guard Assertion. You can find a detailed description of it on page 490 in the excellent book xUnit Test Patterns by Gerard Meszaros (highly recommended). Normally, I don’t use this pattern myself, since … Read more
Vectorization (as the term is normally used) refers to SIMD (single instruction, multiple data) operation. That means, in essence, that one instruction carries out the same operation on a number of operands in parallel. For example, to multiply a vector of size N by a scalar, let’s call M the number of operands that size … Read more
Here are some some answers to your questions: Should both test and production environments be built from source control? YES Should both be built using automation – or should production by built by copying objects from a stable, finalized test environment? Automation for both. Do NOT copy data between the environments How do you deal … Read more
Read this line, and do what it says twice.
If a framework is opinionated, it lock or guides you into their way of doing things. For example: some people believe that a template system shouldn’t provide access to user defined methods and functions as it leaves the system open to returning raw HTML. So an opinionated framework developer only allows access to data structures. … Read more
See: RFC 3092: Etymology of “Foo”, D. Eastlake 3rd et al. Quoting only the relevant definitions from that RFC for brevity: Used very generally as a sample name for absolutely anything, esp. programs and files (esp. scratch files). First on the standard list of metasyntactic variables used in syntax examples (bar, baz, qux, quux, corge, … Read more
In Debugging Microsoft .NET 2.0 Applications John Robbins has a big section on assertions. His main points are: Assert liberally. You can never have too many assertions. Assertions don’t replace exceptions. Exceptions cover the things your code demands; assertions cover the things it assumes. A well-written assertion can tell you not just what happened and … Read more
Since I’m the current world record holder for the most digits of pi, I’ll add my two cents: Unless you’re actually setting a new world record, the common practice is just to verify the computed digits against the known values. So that’s simple enough. In fact, I have a webpage that lists snippets of digits … Read more
While vs. Do While
You are correct: if you need to inject 13 dependencies into a class, it’s a pretty sure sign that you are violating the Single Responsibility Principle. Switching to Property Injection will not help, as it will not decrease the number of dependencies – it will only imply that those dependencies are optional instead of mandatory. … Read more
