10 Reasons Why You Need DevOps

1. Dynamic Resourcing

I need a name for both models and, in fact, the name wise to split development and operations into two teams would be DevOps, but unfortunately it is the catchy phrase not to split them, and on this article we call this model Ops / Dev and we use DevOps for the model where they are combined? Suggestions about a postcard for a better way to do it. Under Ops / Dev, we have people X Ops and people Y Dev. In DevOps, we have people X + Y and can work on all priorities. Sometimes it will be development (which leads to a large version, or if there is a priority commercial requirement), and sometimes it will be an operation (if there are assembly problems or we just made a large version). Either way, the feature is easy because people have transferable skills so they can do one or the other. Under the Ops / Dev template, you cannot easily deploy a developer to fill in for the Ops team or a Ops person to complete for a developer.

This is important because the loads between the teams vary significantly and you really need to use features for full load on both teams. It is not only inefficient but dangerous. Developers or off-duty killers can do incredibly stupid things without proper control, so you have the double problem (what’s a Whammy exclusive? What’s a Whammy?), A frantically busy team, and a team with nothing to do with violence with things you’d rather not touch.

2. Less Overhead

You can call Lean Six Sigma, or not BS, but the answer is the same. With an Ops / Dev template, you have introduced many things that you do not necessarily need. Not only do you have two teams, but you do have a transfer process and a lot of hangers that facilitate a process that you probably did not need in the first place (the same as above, only if you have a mission-critical business application, is a cost to do business for you. I’m talking about applications that do not need it.

Viewing. Do you have a version manager, maybe a change manager? What do you think of a meeting every fifteen years covering the next transitions to production? What about a process of increasing problems between Ops and Dev? A warranty period? Even if it’s just a phone call or an email or two, it’s a process you simply do not need. What makes the US health system the most expensive in the world? It is not the doctors and the nurses, it is the administrators who cling to all the treatments. Get rid of it and you’re halfway to a good solution.

DevOps

 3. Ownership

This is probably the biggest problem of all. Who owns the application in an Ops / Dev model? Oops? Dev? You’ve probably created a new role to own it (see above). But how do your developers feel about it? (And for that, Ops folks as well?) I bet they feel like compromised weapons, working on the task in front of them and probably measured about the only outcome they were asked to achieve. It is not property; it is work-oriented work. But see what happens if you hold them responsible for all this?

If they find something that needs to be repaired while they are working on something different, they will repair it. This is what you do when you own something. You resolve or report a problem you encounter. When you’re a hired gun, you just do what you’ve been asked to do, no questions asked.

4. Agile

If Agile is the right methodology for what you are doing (and it might not be), then Ops/Dev probably isn’t. Agile is about small teams, high-touch communication, and frequent reassessment of the top priorities coupled with regular delivery. Sounds like DevOps to me, not Ops/Dev with the formal handovers and gates and whatever another sticky tape you have put in to make it not fail.

5. Increased Stability

Associated with the above resourcing problem and ownership, DevOps’ ability to do things more conveniently. With Ops / Dev, your operations team could go crazy trying to solve problems while your Dev team is happy and unconsciously preparing to release more chaos in the environment with the next release.

In DevOps, this is self-regulating. You simply do not have the people available to make the next version if everyone is flat repairing the problems of the last one. And anyway, if the property is sitting with a team that would be crazy enough to do it, even if you could?

Software Testing Interview Questions for Beginners 2017

1. What is the MAIN benefit of designing tests early in the life cycle? 

It helps prevent defects from being introduced into the code.

2. When is used Decision table testing?

Decision table testing is used for testing systems for which the specification takes the form of rules or cause-effect combinations. In a decision table the inputs are listed in a column, with the outputs in the same column but below the inputs. The remainder of the table explores combinations of inputs to define the outputs produced. Software Testing Training in Chennai

3. What is the difference between Testing Techniques and Testing Tools?

Testing technique: – Is a process for ensuring that some aspects of the application system or unit functions properly there may be few techniques but many tools.

Testing Tools: – Is a vehicle for performing a test process. The tool is a resource to the tester, but itself is insufficient to conduct testing.

4. What is component testing?

Component testing, also known as unit, module and program testing, searches for defects in, and verifies the functioning of software (e.g. modules, programs, objects, classes, etc.) that are separately testable. Component testing may be done in isolation from the rest of the system depending on the context of the development life cycle and the system. Most often stubs and drivers are used to replace the missing software and simulate the interface between the software components in a simple manner. A stub is called from the software component to be tested; a driver calls a component to be tested.

5. What are the Structure-based (white-box) testing techniques?

Structure-based testing techniques (which are also dynamic rather than static) use the internal structure of the software to derive test cases. They are commonly called 'white-box' or 'glass-box' techniques (implying you can see into the system) since they require knowledge of how the software is implemented, that is, how it works. For example, a structural technique may be concerned with exercising loops in the software. Different test cases may be derived to exercise the loop once, twice, and many times. This may be done regardless of the functionality of the software.

6. What is the difference between re-testing and regression testing?

Re-testing ensures the original fault has been removed; regression testing looks for unexpected side effects.

7.What are semi-random test cases?

Semi-random test cases are nothing but when we perform random test cases and do equivalence partitioning to those test cases, it removes redundant test cases, thus giving us semi-random test cases.

8. What are Test comparators?

Is it really a test if you put some inputs into some software, but never look to see whether the software produces the correct result? The essence of testing is to check whether the software produces the correct result, and to do that, we must compare what the software produces to what it should produce. A test comparator helps to automate aspects of that comparison.

9. What is Boundary value testing?

Test boundary conditions on, below and above the edges of input and output equivalence classes. For instance, let say a bank application where you can withdraw maximum Rs.20,000 and a minimum of Rs.100, so in boundary value testing we test only the exact boundaries, rather than hitting in the middle.  That means we test above the maximum limit and below the minimum limit.

10. What is "use case testing"?

In order to identify and execute the functional requirement of an application from start to finish "use case" is used and the techniques used to do this is known as "Use Case Testing".
