As discussed in Part 1, by segregating our focus on developing code that behaves as expected from the focus on developing code that will be well structured, we have achieved the ability to eliminate wasteful and error prone manual chores.

Automated testing is a way to ensure you can repeatedly examine your code as you make changes by running a series of tests. Since these are automated, you have the ability to execute all tests with one programmatic call rather than hoping a developer runs all tests. This also allows the effort of writing tests […]

Test-Driven Development (TDD) involves the repetition of a very short development cycle that begins with an initially-failing test that defines the required functionality, and ends with producing the minimum amount of code to pass that test, and finally refactoring the new code. Michael Sorens continues his introduction to TDD by implementing the first tests and introducing the topics of Test doubles; Test Runners, Constraints and Assertions.

Test-Driven Development (TDD) has a misleading name, because the objective is to design and specify that the system you are developing behaves in the ways that the customer expects, and to prove that it does so for the lifetime of the system. Michael Sorens starts an introduction to TDD that is more of a journey in six parts.

Test-driven development is often taught using simple examples, such as calculating the scores for a game of ten-pin bowling. Using the same practice effectively on a real code base isn’t as easy. This article covers some of the questions that arise when dealing with larger code bases and changing requirements.

There is a table tmp_tab:
CREATE TABLE tmp_tab ( id int, val int );
INSERT INTO tmp_tab VALUES (1, 1), (2, NULL), (3, 3), (4, 4), (5, 5);You want to order the rows ids by the following expression:
ISNULL(val, id) + 1Which of the following queries produces the expected ordering and why? (Select all correct) See possible answers
