Ministry of Testing Podcast

The Philosopher and the tester

In this episode of the ministry of testing, Israel Alvarez talks about his transition from a philosopher background to becoming a QA tester. He believes there is a lot of positives from his philosophy background that has helped his career as a software context driven tester. Philosopher raises topics and concepts that forces you to think and so does testing so it was fairly relatable and easy to apply his acquired skills from philosophy. Being able to critically think is key to becoming a great QA tester. Knowing what to test for and how to test for makes this arguably one of the hardest things to do. Often as a tester, you have to analyze your own thinking, many times risking the analysis paralysis syndrome. As a math and philosophy major, Israel was always faced with problems that often didn’t have plan cut simple solution so he always had to try and apply what he had learned to get the job done with thinking outside the box. That’s what makes testing so hard. Its easy to come up with some things to test in a code or program but finding out things that need to be tested requires a thorough understanding of the product or software that is being developed. You often need to understand it even more than the creators of the product. They only way you can adequately test a product is to find its boundaries, applications and purposes and see what you can do to challenge these thing or break them. In a start up for instance, there are deadlines, scope changes and many challenges’ that testers have to endure. Proving your value as a tester is very important in the early stages of testing. Learning to articulate and defend ones view, as a tester is an essential skill that every tester needs to have to grow. This is a major challenge because developers often have to prove their point and findings to the programmers. Programmers often have strong views and passion for their work and in order to properly nit pick and criticize defect or bug that is in their work, you need to be able to establish yourself and emphasize overall product quality in your defending’s. As a tester, developers often have stressed feelings towards your work. It’s just the nature of the job as a QA manager or tester. It’s your job to ensure that the developers have put out the best possible product or software they can produce.




38. How to be a Programmer: Personal and Team Skills


Coding blocks podcast is presented by Joe Zack, Michael outlaw and Allen Underwood. In this podcast episode, the gang talks about what it takes for someone to become a good programmer for his company and his team. One thing that is known to be a problem of the technology world is the lack of people with adequate teamwork and collaboration skills. I picked this particular podcast episode because I felt this would help anyone who reads. They talk about personal skills and practices that just makes one a better programmer in the industry. The main problem that occurs during team tasks is estimating how long a coding task will take. You want to please your boss and he also wants to please his boss so understanding each other and establishing that mutual trust makes it easy to work coherently in the task at hand. One challenge that most programming teams experience with their leaders is scope creeping. Scope creeping is a project management term that refers to changes, continuous or uncontrolled growth in a project’s scope, at any point after the project begins. This can occur when the scope of a project is not properly defined, documented, or controlled. It is generally considered harmful. This is because it causes problems and situations that are often not accounted for. Usually with every programming project, specifications are laid out and a timeline estimate is created for people to adhere to but once the scopes begin to change, unaccounted scenarios begin to happen. As a programmer, great communication between team members and leaders brings success to the project. This is because everyone has different level of expertise and often tasks and timelines are drawn based on the programmer’s expertise. Another thing that needs to be accounted for is vacations and sick absences. It’s the task of the programmer and team members to show commitment during tasks. You cannot take a 2 weeks or 1 week vacation when you know that the team is waiting for you to build the baseline site for people to continue developing on. This strings back to the trust issue. Efficient communications has to be open between members of teams to properly resolve issues such as these. Again communication thrives in teams when everyone is on the same level. Usually in teams, everyone has different background and finding that middle ground to communicate effectively helps the team thrive.





Clean Architecture – Components and Component Cohesion

Episode 71

Coding blocks podcast is presented by Joe Zack, Michael outlaw and Allen Underwood. In this podcast episode, they squad begin by talking about components cohesions in architectural designs. Cohesion in software designing refers to the degree to which the elements inside a module belong together. In one sense, it is a measure of the strength of relationship between the methods and data of a class and some unifying purpose or concept served by that class. In another sense, it is a measure of the strength of relationship between the class’s methods and data themselves. Cohesion is an ordinal type of measurement and is usually classified under two categories, “high cohesion” or “low cohesion”. According to the team, there was a principal known as the fish bowl principal, this was employed in system building and architectural design for so many years. It was believed that the fish would eventually grow to fit the bowl it was placed in. But that has changed over time, with services like AWS and other cloud functionality, developing software of any size is easily manageable. Scalability is often handled by high performance systems that allocate resources to where is it needed most and vise versa when it’s not in demand. A big part of this new trend of software reuse is propelled by the open source project that currently runs the software industry. Building components or software in components also propels this new trend of code reuse. This is because in components, code is built to be self-dependent and sufficient to run on its own. It is viewed as a module that fits a part of the big puzzle. Testing for modules and components do not break the original code as it is tested as a single entity that interacts with the overall project. Another topic that gets discussed by the group is the common closure principal. The common closure principle consists of classes that change for the same reason and at the same time. This is similar to the single responsibility principle. This simply means that if the character of the class is changing, then the component is also gonna change. We need to make sure that the component is only changing for one reason only and if there is more than one reason, then there should be more than one component. Overall, this episode went very in-depth to technical practices and techniques that are used to develop components and architecture in software creation. This level of in-depth was a little too much for what we are studying but I felt it was necessary as it gets us thinking about how to build software in components and parts and start learning how to allocate functionalities to individual components.

Episode 33 —Testing in Data Science

In this week’s testing podcast episode, Brian explores testing in data science with the famous Katharine Jarmul. Katharine is a expert in data science and machine learning. She mainly uses python to write unite tests for her projects. I picked this podcast because after listening to this, I learned more about how to put together testing teams, how to manage and direct traffic in a testing team and how to be the driving force for success in the team. According to her, no matter how much we know as a team, with each testing project, we need to bring together all our resources and ideas. Testing often goes out of the scope of what is considered the norm. This is because in testing, we normally try to find the boundaries and limits if products and software. As a teacher and owner of a consulting company, Katharine often spends her days developing testing strategies that requires the implementation of new and modern testing technologies such as Integrating QA through agility and TCoE , Higher Automation Levels with a focus on security and Context driven testing.


Integrating QA through agility and TCoE

Though agile development teams have been around for a long time, agility in testing is still nascent. With the continuous pressure to quickly deliver software, businesses are investing time and money into setting up a TCoE with the objective of reducing CoQ, increasing test effectiveness and generating more ROI out of testing. From 2011 to 2014, the number of operational TCoEs has increased from 4% to 19% and is expected to increase further in the future.


Higher Automation Levels with a focus on security

System robustness and security has always been a top priority but with growth in social media and mobility and need for software that can be integrated to multiple platforms, systems are becoming more vulnerable. There is a pressing need to ensure enhanced security, particularly in applications handling sensitive data. This is causing QA to focus more on security testing.


Context driven testing

The challenge for businesses to maintain central hubs of hardware, middleware and test environments necessary to comprehensively test them has caused context driven testing to become more popular as it ensures more testing coverage from diverse angles. It is expected that this will impact skill development among testers, as there will be more demand for testers with exposure to different contexts.




Clean Coding- Coding Blocks

Episode 49 – Clean Code – Comments Are Lies



Coding blocks podcast is presented by Joe Zack, Michael outlaw and Allen Underwood. In this podcast episode, the authors discuss about creating good and clean code and eliminating as much comments as possible. Initially, I was very confused with this concept by pro developers because in my first intro to java class, my teacher emphasized on making sure that we adequately commented thoroughly on methods and functions that we wrote. There were even points that was taken for now properly commenting codes then all of a sudden, my CS 443 my professor tells me that commenting is not really a good practice since your code should be written so well that understanding the though process and program should very easy. But the more I thought about this, the more I understood what was being taught by the teacher and now this podcast episode. No one writes comments for print statements because it’s so rudimentary that, everyone basically understands it by looking at it. That’s how our algorithms should be designs. Code Readability and understanding should be the goal of all developers who walk out of school. Again using comments in clean code has its pros and cons. They almost never get updated while the code gets updated and fix. They tend to mislead because they are not often updated. They propagate lies and misinformation’s because as the code gets modified and updated, they are often left untouched. The only exception to this rule of thumb is when one is coding a public API that would be used by other developers. Comments are looked as a way for programmers to make up for their shortcomings in programing. If methods and variables are named and designed properly there would be no need commenting. Time used to create comments can be used to optimize the software program to increase its readability and logic flow. Another bad thing about comments is when they are not obsolete but just misleading. Also inaccurate comments put the developer in the wrong frame of mind and logic. The proper approach is utilizing refactoring and clean code techniques that build program structure and design instead of attempting to explain bad coding with comments. Ultimately, it makes sense that developers wanted to explain their thoughts and processes with comment but its just more effective when the thought process is explained in the logic and functionality of the codes and method.

#6 – Testing Talks

Testing Talks – Episode 169 With JeanAnn Harrison.


In this week’s testing podcast episode, Joe interviews JeanAnn, a Software testing manager who has been in the software quality assurance field for over 2 decades. JeanAnn begins by addressing techniques and best practices that make for a fluid testing process. I chose this particular episode because JeanAnn addressed automation in testing and critical thinking in testing. With the development of modern technology, software automation is the next big thing in the world today.

Another big thing she talked about was critical thinking. Critical thinking often refers to the ability to try different thought processes and develop new methodologies to achieve an already familiar goal. The ability to think outside the box, pushing yourself to look at things in a different way. To evolve ones thinking ability in testing, we can try to look at things outside the software-testing field. By doing this, one is able to develop logical means that are often necessary to find product boundaries and limits. Asking yourself questions like how? , when? , what ? , where ?. These simple questions often answers most of the questions for the software testers and help develop solutions and bugs that need to found. By asking these questions, you are able to see how the software or product could be integrated into computer systems, the kind of problems that can arise by implementing the new product/technology and what can be done to resolve issues should they arrive. Another big thing that she addressed was understanding software’s users and customer base. Developing apps and programs without expected audience leads to many problems in the software world. Imagine developing a mobile application for 70 year olds but its integrated into the latest iphone technology. This would not work out because most of the people in that range no longer have the ability to adapt to new technology or even use a cellular device. Again imagine developing a walker for blind people which has an activation switch installed on the side with an on and off reading. This will be physically challenging and difficult for the blind to optimally use the product. It might be the best product that all blind people needs but its inability to incorporate and account for the blind would instantly make it a bad design or a bad product to acquire. Simply put if you know your user base, you are able to find out what needs to be designed for the product to properly fit the needs of the users and customers.




#5– Episode 67

Episode 67 – Object Oriented Mistakes

Presented by Joe Zack, Michael outlaw and Allen Underwood, the group addressed many object-oriented mistakes that coders often make. I found this to be an interesting podcast because like many of us upcoming coders, we are taught mistakes that cause problems when attempting to develop in an object-oriented environment. From the previous design patterns episode, we were able to understand the best situations and the proper design pattern that should be used. For example when using domain designs, we have learned not to use domain anemic models. Before we continue, anemic model is the use of a software domain model where the domain objects contain little or no business logical validations, calculations, business rules etc. These are typically called bags of properties with getters and setter without any kind of behavioral type method. The domain model objects cannot therefore guarantee their correctness in any moment due to lack of validation and mutation logic which is usually placed somewhere outside the class being addressed. One would ask, why is this considered an anti-pattern in todays programming world, well first of all, it disrupts the concept of object-oriented design. This design contracts what is implemented when on opts to use the object oriented design. Object orientation allows objects to have states and sessions but anemic causes stateless objects. It is great for just a simple application because there is a clear separation between logic and data unlike object oriented programing. Simple applications also do not require a ton of logic to be implement. They do not need methods with behavioral code in them. After this point, Micheal spoke of another anti-pattern. This pattern was known as the base bean anti-pattern. This is when you inherit functionality from a utility class instead of delegating to that utility class. The issue associated with this practice is that defeats the purpose of inheritance. Inheritance is used for the wrong reasons. The main purpose of inheritance is to create a hierarchical order in which code information can be managed and understood. Wrong implementation of inheritance disrupts object properties and class properties. Overall, design patterns are created for incoming developers and even intermediate developers to have a guide that can be used as a reference. Thy provide us with a way to getting things resolved or better yet, the first solution that solved the problem. It is up to every developer to learn beyond that and recognize how they can utilize the already laid out platform to their own coding needs and development.
