Kent Beck explains his 'Alternative work flow ' called Test, Commit or Revert. It consists of making small changes to the code in order to always have the test on green (passed), so as Kent explained on this podcast, if you know that you have to make two changed in order to make the test pass first you need to make the first change but in a way that doesn’t corrupt the test of make the test fail. It's all about keeping the status of the test green.

TCR has a big impact on the confidence of a programmer because by having a positive output on a test case that has no other intention that to "break" your code boosts your belief in yourself (in your programming skills or your capacity to debug problems).

I was actually surprised when I heard this because I'm used to working the opposite of TCR watching everything turn red and breaking code until you magically fix it. I recently learned TDD (Test Driven Development) in my Software Architecture course, and it was an eye opening learning experience because first I never heard of this term or way of programming. Second of all I believe that I learned it the hard way because the teacher just went over TDD in a light manner and we had homework the next day of solving a problem in Java that he design for us and create our own test cases that we thought could cover all of the issues that might pop up. So I turned in my homework and minutes later the teacher was testing our code with more than 100 test cases he design for the problem. We had no idea he would test our code so thoroughly and I'm glad to say that my code just failed 4 of those test cases.

I can't really form an opinion about whether I prefer TDD or TCR because I have not worked with the last one. But what I can say is that I'm intrigued with Kent's idea because anything that can help build up my confidence on my skills with programming I'm here for it.

Disjoint: blocks should not overlap 2. What is an Input Domain Model (IDM)? Two Approaches to Input Domain Modeling: A. Interface-based approach. 􏰀 Develop characteristics directly from individual input parameters. 􏰀 Just use properties of the domains without considering the actual function under test. B. Functionality-based approach 􏰀 Develop characteristics from a behavioral view of the program under test. 􏰀 Use your understanding of what the system should do. 3. What gives more tests, each choice coverage or pair-wise coverage? Each Choice Coverage (ECC) states that one value from each block for each characteristic must be used in at least one test case. For example, for partitions [A, B] [1, 2] we can get [A, A], [B, B], [1, 1] and [2, 2] which are clearly redundant. Pair-

Final Exam Questions

1. Software fault: static error in the code. Software error: internal, not a normal behavior of the program due to a fault. Software failure: external, visible failure of the program. That it doesn't work basically. 2. Beizer discussed the goals of testing in terms of the “test process maturity levels” of an organization, where the levels are characterized by the testers’ goals. Level 0: Testing and debugging are the same. (Worst level) Level 1: Testing is only to find that your code doesn't work. Level 2: Get defensive or make an issue personal with testers because they broke your code. Level 3: Understand the job of a tester and take feedback as constructive criticism. Level 4: Become an expert software tester and make extreme good quality software. Work in harmony with testers. 3. Static Code Analysis is usually performed as part of a Code Review (also known as white-box testing). is a method of debugging by examining source code before a program is run . It’s done by ana

From flip learning to almost conventional teaching (since you grade your own exam) he's not afraid to make changes and give students the chance to explore self learning and to take responsibility on when and how they learn the content of the course. This is a skill that is very important acquire and that is needed on a daily basis in every job in the tech field. Personally i enjoyed the Software Quality and Testing course. There are many students that might not like this method of teaching applied on this course because it requires them to take responsibilities on their own learning and some students can't handle this type of control over their own learning. No negative feedback for this course, only that maybe some classes should be online.
